2 Collaborative Working This Multi-Professional Clinical Skills Pack aims to establish a standardised training for the insertion of and care of chest drains skills for medical, nursing and relevant allied health care professions. NHS Lothian, University of Edinburgh, NHS Education for Scotland and the Scottish Clinical Skills Managed Educational Network have developed it in collaboration. The pack has been designed to be adaptable to the local context, with agreement between the collaborators to alter only sections 1, 3 and 4. All other sections are standardised and cannot be altered out-with the agreed review process. Copyright Version Number: 6 University of Edinburgh & First review date: January 2009

5 Section 1 Rationale for the Chest Drain Programme This clinical skills programme has been developed to enable practitioners to develop their knowledge and skills in the insertion of and the care of chest drains. Adopting a multi-professional approach to clinical skills training will promote standardised practice in the delivery of health care procedures, will encourage effective working relationships and will provide patients with access to multi-skilled, flexible health care practitioners. The programme is suitable for any health care practitioner currently working or training to work in the NHS, in the UK, who is involved as part of their work in the insertion of, removal of or the care of patients with chest drains in place. How to Use this Programme This clinical skills programme will support practitioners in their studying, enabling them to work at their own pace, and learning about chest drains in the context of their own practice. Each participant should negotiate a suitable time frame for completion of the suggested activities contained within the programme with their assessor. Participants should aim to complete the programme within a 12 weeks time frame. Although, for students it may be possible to extend this time, to say, an academic year, to allow the student to have enough exposure to chest drains. It will be appropriate for some healthcare practitioners to undergo training in both the insertion and care of chest drains and some only the on-going management and removal of chest drains, depending on their scope of professional practice. However, all healthcare practitioners that may assist with the insertion of chest drains or care for patients with chest drains in place require some familiarity with the procedure and the under-pinning theory behind the skill. Practitioners should begin working through the pack prior to attending a simulated practice session. Practitioners should arrange supervised practice with an assessor in their own clinical area or within an undergraduate clinical placement. There are circumstances when practitioners will require supervised practice out-with their own clinical area and this should be negotiated with supervisors/managers. Supervised practice should only occur following attendance at a simulated practice session. Unsupervised practice should only occur when the assessor deems the practitioner competent (successful completion of both theoretical and practical assessments). An assessor will be a practitioner who is competent in the skill of chest drain insertion or management and familiar with this programme. A flow diagram explaining the process of clinical skills training can be found at Appendix A. Throughout the text, activities are provided which will encourage the use of reflective, decision-making, observational and cognitive skills. N.B The Professional Issues good practice study guide is a core pack designed to prevent repetition of content in subsequent packs. All practitioners must complete the Copyright 2008 Version Number: 6 University of Edinburgh & First review date: January 2009

6 Professional Issues pack prior to commencing any other skills pack. Some activities in subsequent packs will require you to refer back to the Professional Issues good practice study guide. The study guide is available in hard copy on the mobile unit or from the CS MEN office ( Assessment includes: Answers to theoretical assessments must be checked by the assessor using the marking guide and the procedural checklists provided. Assessors should guide practitioners to reference material in the resource pack if the practitioner does not provide similar answers to the marking guide. Practitioners will be assessed using procedural checklists during simulated practice sessions. Practitioners successfully completing this assessment are deemed safe to undergo supervised practice in their clinical areas. Assessors must use the Assessment of Skill Acquisition tool provided to assess the practitioners practical application of the skill during supervised practice. The Assessment of Skill Acquisition form should be completed a minimum of 3 times. The number of assessments required will depend on individual competency. Completed assessment forms should be retained by the practitioner and not the assessor. The practitioners who are deemed not yet competent must undergo a further period of supervised practice. For some, such as undergraduate students, completion of simulated practice and theoretical assessment will be all that is required to complete the pack. However, the student, either Nursing, AHP or Medical will still require to undergo supervised practice and Assessment of Skill Acquisition at the post-graduate level if Chest Drain competencies are required. Evaluation: This is a new clinical skills training pack, therefore we would like to know what you thought of the pack by taking a few minutes to fill in the evaluation form on completion. To ensure accurate recording and update of the clinical skills database, please ensure you return the completion certificate enclosed when you have finished the pack. Copyright Version Number: 6

9 Section 2 Introduction Chest drains are inserted into the pleural cavity to remove air or fluid. They are used in many different clinical areas such as In a trauma patient in the Emergency Department a chest drain may be used to remove blood or air from the pleural cavity or decompress a Tension Pneumothorax In a patient with lung cancer in the Respiratory ward a chest drain may be used to drain a malignant pleural effusion Therefore doctors, nurses and allied health professionals throughout many settings need to be able to either insert or care for chest drains safely and competently. This multi-professional chest drain pack is designed for different levels of competencies as required within your clinical environment and scope of professional practice. The competencies that can be selected from this pack are that of Large bore chest drain insertion including pre-hospital insertion Small bore chest drain insertion using Seldinger technique Management, including removal of a chest drain This pack does not cover the insertion of or on-going management of chest drains in children as this is a highly specialised area of practice. Tip of drain in axilla Large bore chest drain Figure 1 Large bore chest drains on x-ray in patient with multiple rib fractures and surgical emphysema Chest drain insertion has been shown to be associated with 3% early and 8% late complications. Also a recent report (May 2008) from the National Patient Safety Agency (NPSA) has highlighted some of the risks associated with chest drain insertion. They report 12 deaths directly related to chest drain insertion between 2005 and 2008 in England. Some of these deaths were due to damage caused to major structures such as the heart and liver during chest drain insertion. Other adverse events related to poor chest drain management, such as inappropriate clamping of the drain. Best Practice Statement Chest drains should only be inserted and cared for by competent staff who are properly trained in this procedure with appropriate supervision Rationale: There are significant risks associated with the insertion and management of chest drains. Source of Evidence: BTS guidelines and NPSA Copyright Version Number: 6

10 Indications for Chest Drain Insertion There are many reasons why chest drains are inserted in the clinical area. Chest drains are considered to be either large (24-32 F gauge) or small bore (10-14 F gauge). Small bore chest drains are normally inserted by the Seldinger or needle over wire technique. Forceps for blunt dissection Holes in side of drain Flexible introducer Connector for underwater drainage system tubing Figure 2 Large bore chest drain (32 F gauge) Holes in side of drain Figure 3 Small bore Seldinger chest drain (12 gauge) Connector for underwater drainage system tubing The following lists potential indications, but is not exhaustive: - Large-bore chest drains Traumatic haemothorax (blunt or penetrating) Tension pneumothorax (only after needle decompression is performed) Traumatic simple pneumothorax Post cardiac and thoracic surgery Drainage of pus from an empyema Smaller-bore chest drains Simple pneumothorax with lung that does not re-expand with aspiration or recurs Secondary pneumothorax in patient with lung disease Pneumothorax in any ventilated patient Removal of fluid from a malignant pleural effusion Copyright Version Number: 6

11 Anatomy and Physiology In order to insert, remove and manage chest drains safely and competently practitioners need an understanding of the anatomy and physiology of the chest wall and pleural cavities. A Study has shown that while nurses tend to have a good knowledge of the management of chest drains, they are less clear about the underpinning theory, including the indications for chest drain insertion. The anatomy of the thoracic wall is important to think about when preparing for chest drain insertion. Between each of the ribs lie the intercostal spaces, which are breached over by the intercostal muscles. Each intercostal space has a nerve, artery and vein running through it. These vessels lie and run just under the rib. This means that a chest drain should be inserted just above the upper border of the rib to avoid damage to the neuro-vascular bundle. The long thoracic nerve runs down the lateral border of the thorax and so chest drains should be inserted anterior to the mid-axillary line to avoid damage to this structure. Figure 4 The neuro-vascular bundle inferior to the rib Remember that the normal lungs are covered with a thin layer of pleural fluid that acts a bit like two wet pieces of glass i.e. they can move sideways but it is difficult to separate them. The intra-pleural pressure in this fluid is below atmospheric pressure, thereby stopping the lungs collapsing away from the thoracic cavity. If air enters the pleural space (pneumothorax) then the lungs will collapse. For a chest drain to work it must be connected to an airtight seal with an underwater collecting chamber (1,2 or 3 chambers) or a one way (Heimlich) valve with collecting bag. Underwater seal drainage systems are not used in pre-hospital situations. In a patient with a chest drain in place, on expiration, positive intra-pleural pressure is generated. This causes fluid or air in the pleural cavity to be expelled which with an underwater unit will then drain or bubbles one-way through the water. Air passes to the outside air and fluid or blood collects in the bottle. The drain tubing should always be 3 cm below the water level (often pre-marked on bottles). Gravity and differences in pleural pressures between the thoracic cavity and the atmosphere allow this to happen although gravity will work in reverse if the drainage system is lifted above the chest drain when fluid or air will be sucked back into the chest.

13 Risk Assessment NPSA - Questions to ask yourself before inserting a chest drain 1. Does it need to be done? 2. Does it need to be done now? 3. Am I competent to do this? 4. Is supervision available? 5. Am I familiar with the equipment? 6. Does patient require a large trauma drain with open technique or a smaller drain with Seldinger technique? 7. Is USS available, especially if inserting a drain for fluid? Contraindications Lung adhered to the chest wall on x-ray Bullous lung disease (caution as what looks like a pneumothorax may in fact be a bulla) Bleeding disorder (relative contraindication if INR raised or platelets low, balanced with degree of urgency of drain insertion) Best Practice Statement Unless in an emergency the patient should have a chest x-ray performed before drain insertion Rationale: Confirm that drain insertion is indicated and confirm side of placement Source of Evidence: BTS guidelines Precautions Patients currently receiving anti-coagulant therapy increased bleeding time post procedure Patients with chronic respiratory problems who may not be able to tolerate lying flat Patients with chronic obstructive pulmonary disease- confirm that an apparent pneumothorax is not a bulla before inserting a drain Patients with a tension pneumothorax should have needle decompression performed prior to insertion of a chest drain Best Practice Statement In non-urgent chest drain placement consideration should be given to the use of USS to guide insertion Rationale: Make sure drain inserted into right area and minimise risk of damage to other structures Source of Evidence: NPSA Copyright Version Number: 6

14 Psychological considerations Previous personal experience the patient may have had an unpleasant experience of having a chest drain inserted previously. 50% reported significant pain on chest drain insertion (BTS) Needle phobia consider cautious administration of a low dose of IV benzodiazepenes. Fear - reassure the patient Understanding having too much/too little information Best Practice Statement Always give analgesia and consider anxiolytics unless contra-indications Rationale: Minimise pain and anxiety. Source of Evidence: BTS guidelines Patient Education Communicating and informing the patient of exactly what the procedure involves can reduce anxiety and fears. The patient should be made aware of why he/she is having the procedure, the benefits and the potential complications before obtaining informed consent. Establish if the patient has any known allergies prior to the procedure the patient may have an allergic reaction to local anaesthetic. It is important that the patient should know about care of their chest drain, including important safety aspects, however this can normally wait until after the drain has been inserted and will be dealt with after the procedure. Patient Positioning and site of insertion Lie patient down if they are able to with the hand of the arm on the side that the drain is going to be inserted into behind the patient s head or held abducted and externally rotated by an assistant. Chest drains should be inserted through the safe triangle as this minimises risk to surrounding structures (long thoracic nerve, muscle, breast, axillary structures). Insertion through the safe triangle (4 th or 5 th intercostal spaces in anterior axillary line) also helps to prevent the drain being placed too low with the potentially fatal risks of damage to the liver and spleen. Boundaries of safe triangle are Lateral border of pectoralis major anterior, mid-axillary line posterior, level of nipple inferior. Griffiths in 2005 noted that 45% of junior doctors chose a point of insertion out with the safe triangle, with 25% choosing a point too low (risks damage to liver and spleen). Occasionally drains are placed in an anterior or posterior position to access a loculated collection of fluid. This is a specialised procedure and should be performed under ultrasound guidance wherever possible and only by those who are competent in this procedure. Copyright Version Number: 6

The patient should be monitored, receive oxygen and have an intravenous cannula inserted before the procedure. As well as the competent practitioner who will insert the drain there should be an assistant present who is trained in the care of chest drains AT ALL TIMES. This assistant is required to open packs and equipment so that asepsis is maintained. They are also responsible for monitoring the patient and doublechecking safety aspects such as side of insertion. Activity List the boundaries of the safe triangle and explain why drains should only be inserted through this area Copyright Version Number: 6

16 Risk Factors of Chest Drain Insertion As with any invasive procedure, there are risks to the patient and practitioner. Practitioners need to be able to assess the risk and decide if the benefits outweigh the risks, to reduce risks where possible and to be able to troubleshoot when things do not go to plan. The table below is not exhaustive, but highlights some of the risks and problems associated with the procedure. Risks Associated with Chest Drain Insertion Risk Cause Practitioner s Action Trauma to underlying structures Pain Local Anaesthetic toxicity Re-expansion pulmonary oedema Use of metal trochar Poor anatomical placement (liver, spleen) or poor patient positioning Dilator damage in Seldinger technique Needle damage in Seldinger technique Damage to neurovascular bundle Damage to long thoracic nerve Inadequate analgesia Inadequate local anaesthetic Failure to consider benzodiazepenes Failure to consider safe local anaesthetic dosages of up to 3mg / kg Rapid evacuation of air or fluid from the thoracic cavity Metal trochars should NEVER be used Make sure the drain is inserted in the safe triangle, or use USS if available Do not insert dilator deeper than needed to dilate chest wall Aspirate as you gently insert the Seldinger needle Insert drain along top of a rib Chose site just anterior to mid-axillary line Explore pleural space before inserting drain Consider morphine and midazolam, IV titrated to effect, make sure local anaesthetic inserted down to level of rib and pleura In an average adult 10ml 1.0% Plain lignocaine is sufficient, (20ml maximum). Procedure should be carried out where full resuscitation equipment available No more than 1.5 L should be actively aspirated from a pnuemothorax, empyema or effusion in one go Haemorrhage Coagulopathy or thrombocytopaenia Damage to underlying organs In routine drain insertion correct coagulation problems if possible Avoid trochar use Careful use of needle and dilator in Seldinger technique Copyright Version Number: 6

17 Procedural Guidelines: Chest Drain Insertion Generic Aspects An equipment list is available at Appendices G&H and a Procedural Checklist can be found at Appendices B&C. These will be of use to you during the simulated practice session. Introduce yourself to the patient. Ensure that you have the correct patient by checking name, date of birth and CHI against arm band and notes Examine the patient s chest and confirm clinical findings. CONFIRM SIDE ON WHICH DRAIN IS TO BE INSERTED ON BOTH PATIENT AND X-RAY Explain the procedure to the patient and obtain informed consent. Check for allergies (NPSA recommends that written consent should be obtained where possible) Gather appropriate equipment and select chest drain size (12F small bore 32F large bore). DO NOT SELECT A DRAIN THAT HAS A METAL TROCHAR Ensure patient is lying comfortably with the arm on the side on which the drain is to be inserted behind the head (alternatively if the drain is to remove fluid or pus the patient may sit upright leaning over a pillow or table) Identify the SAFE TRIANGLE and choose point of insertion above a rib to avoid the neurovascular bundle Infiltrate local anaesthetic (maximum 3mg/kg, 10ml 1% Plain lignocaine in 70kg adult is usually sufficient), initially by drawing up a skin bleb with an orange needle and then using a green needle to infiltrate through the soft tissues onto the rib and pleura aspirating as the needle is advanced Administer analgesia (Intravenous Morphine titrated to effect) unless contra-indicated and consider use of an anxiolytic (Midazolam 1-2mg titrated to effect with caution as can cause respiratory depression) Best Practice Statement In the case of a drain being inserted because of chest trauma give intravenous broad-spectrum antibiotics Rationale: Reduces risk of empyema by 5% Source of Evidence Descriptor: BTS guidelines Copyright Version Number: 6

18 TECHNIQUE 1 insertion of a large-bore chest drain Ensure full aseptic conditions are followed at all times Perform surgical hand wash, don surgical gown, mask and sterile gloves Open chest drain pack keeping contents sterile, take suture, antiseptic skin preparation, underwater seal system and chest drain from assistant Clean the skin using an antiseptic skin preparation such as chlorhexidine and swabs in a circular motion from the point of insertion out in a circular motion Apply sterile drapes to maintain sterile field Make an incision parallel to the rib where the drain is to be inserted. Ensure that this is big enough for the drain (approximately 2-3cm) and goes through all the layers of the skin only Figure 8 Skin Incision Many practitioners insert stay and close sutures at this point and clip them to the towels. This avoids the later risk of puncturing the drain with the suture needle Using large forceps (Kelly s or similar) blunt dissect through the subcutaneous tissues (open and close forceps to separate rather than cut tissues. Make sure that you dissect down onto the upper border of the rib and open the pleura (you should feel a sudden give and sometimes a hiss of air or flow of blood) Figure 9 Blunt dissection with Kelly s forceps Copyright Version Number: 6

19 Best Practice Statement Blunt dissection should always be used rather than a metal trochar to gain access to the pleural cavity Rationale: Minimise risk of damage to underlying structures Source of Evidence Descriptor: BTS guidelines Carefully insert a finger into the pleural cavity and sweep round to make sure that the lung is not adhered to the chest wall, avoid damage to the lung with your finger (CAUTION if the patient has rib fractures as these may puncture your glove) Estimate depth of insertion by looking at the markings on the drain and distance from apex of the lung to your incision. All the holes along the length of the drain need to be within the pleural space. Note: holes that are invisible due to being deeper than the skin but superificial enough to lie within the subcutaneous tissue will still cause surgical emphysema Insert the drain through the hole in the pleura and into the cavity; aim the drain towards the apex (some drains come with a plastic introducer which helps to facilitate this). Remove the introducer and place a thumb over the end of the drain Figure 10 Drain insertion DO NOT LET GO OF THE DRAIN until it is safely sutured in place Attach the end of the drain onto the underwater drainage system (making sure that the drain is 3cm below the water level) and place the chest drain bottle below the patient Figure 11 Connect to tubing Copyright Version Number: 6

20 Check that the water in the chest drain is bubbling or swinging, if in doubt ask the patient to cough gently Tie (if inserted previously) or insert a stay suture and a close (mattress) suture that can be used to close the wound when the drain is removed. Make sure you use a strong suture like 1.0 silk or it may snap. Ensure that your stay suture is tight and slightly indents the drain CLOSE horizontal mattress suture STAY Normal Suture Figure 12 Stay and close sutures Figure 13 Stay and close sutures STAY Normal Suture tied at level of the skin and not as a purse string around the CLOSE horizontal mattress suture-leave ends long and curl round drain so it can be readily accessed to close the wound once the drain is removed Figure 14 Sutures tied to maintain air-tight seal Best Practice Statement All large bore chest drains should be sutured in place, purse-string sutures should not be used Rationale: To prevent dislodgement of drain and unsightly scarring Source of Evidence Descriptor: BTS guidelines Remove the drapes Secure the drain to the skin using some cut swabs and a dry adhesive dressing, such as cut MEPORE. There is no role for vast watertight dressings Like SLEEK as these can increase the risk of wound infection Copyright Version Number: 6

21 Figure 15 Cut dry adhesive dressing. Dispose of all waste and sharps appropriately Obtain an urgent chest-x-ray to confirm position and document findings yourself Check routine observations post drain insertion, and record, start a chart for recording chest drain activity Record procedure details, including any complications and results of chest x-ray in the patient s notes. Best Practice Statement Large bore chest drains should be used to drain blood or pus as small-bore chest drains may block. Small bore chest drains are as effective as large bore in draining pneumothoraces and cause less pain and scarring Rationale: selection of appropriate drain size Source of Evidence Descriptor: BTS guidelines After the procedure it is important that the patient should be given important chest drain advice. This predominantly concerns safety, what they can and cannot do, information about how to mobilise, changing position and breathing. They should be advised that they should make sure that the chest drainage system should be kept below the level of the chest at all times. They must seek help immediately if the drain becomes disconnected or they develop respiratory symptoms.

22 TECHNIQUE 2 Insertion of small-bore Seldinger chest drain Ensure full aseptic conditions are maintained at all times Perform surgical hand wash, don apron and sterile gloves Open pack keeping contents sterile, take additional equipment from assistant in a sterile fashion Clean the skin using Antiseptic skin preparation such as Chlorhexidine Apply sterile drape Make a small incision (3-5 mm) in the skin where the drain is to be inserted Using the needle and syringe in the pack gently insert (avoiding excess force) towards the upper border of the chosen rib aspirating continuously until air in the syringe confirms the position of the needle in the pleural cavity Figure 16 Insert needle while aspirating Best Practice Statement Air or fluid must be aspirated before wire is inserted (stop and get help or arrange USS guidance if you cannot achieve this). Both the needle and dilator should be inserted without force Rationale: Confirm correct position and minimise risk of damage to underlying structures Source of Evidence: BTS guidelines and NPSA Hold the needle steady and remove the syringe. Feed the wire gently through the needle into the pleural cavity (AT ANY STAGE IN THE PROCEDURE ONE HAND SHOULD ALWAYS BE HOLDING THE WIRE) Copyright Version Number: 6

23 Figure 17 Insertion of guide wire Remove the needle leaving the guide-wire in place, make sure that the wire does not shear. Feed the first dilator down over the wire and into the pleural cavity. It may be necessary to make the incision a few mm bigger. Repeat the process for the second dilator if present. Note: the dilator only needs to be inserted to a depth that is sufficient for the chest wall to be dilated. Over insertion of the dilator risks damage to thoracic structures and has been identified by NPSA as a significant cause of morbidity with the Seldinger technique. Figure 18 Insert dilator without force Remove the dilator leaving the wire in place. Estimate the depth of insertion on the scale on the drain from the apex to the skin. Feed the 12F chest drain over the wire until it is in the pleural cavity to desired depth Figure 19 Feed drain over wire Remove the wire making sure that the chest drain stays in position DO NOT LET GO OF THE DRAIN NOW Attach the end of the drain onto the underwater seal system and make sure that the chest drain bottle is placed below the patient Copyright Version Number: 6

Modifications 1: The use of USS in chest drain insertion Ultrasound (USS) is used to localise fluid to guide the insertion of a chest drain, which is particularly useful if fluid is locualted. Bedside USS such as the FAST scans used in initial trauma care can also localise a haemothorax. USS localisation and marking of insertion site by Radiologists does not obviate the risks of Copyright Version Number: 6

25 misplacement and the safest practice is to insert the drain while USS guidance is present rather than at a later stage. USS is recommended if blind aspiration of an effusion fails on the first attempt. As the use of bedside USS grows rapidly within specialities such as Emergency Medicine and Surgery, it may become standard practice that all chest drains are inserted under USS guidance. Best Practice Statement Ultrasound guidance is strongly recommended when inserting a drain for fluid Rationale: Minimise risk of damage to underlying structures Source of Evidence Descriptor: NPSA Modifications 2: The Use of Flutter valves In some specialised respiratory environments a flutter valve can be inserted onto the drain rather than the traditional underwater seal drainage system. This one-way valve allows air to leave the pleural space but not re-enter. This system has some advantages in the on-going management of conditions such as a complicated pneumothorax, as it allows the patient to be more mobile and potentially be able to be discharged home with a drain in place. These valves should only be used in specialised clinical settings and have no role in the initial generic management of a patient who needs a chest drain. Note: there are case reports of patients accidentally reversing their own Heimlich valves leading to Tension Pneumothorax. Figure 21 Heimlich Flutter Valve Copyright Version Number: 6

26 Pre-hospital considerations It is vitally important in the pre-hospital setting to ensure that chest drains are only inserted by practitioners who are competent in this procedure. In making the decision as to whether or not to insert a chest drain you must balance the risks and benefits of inserting a drain in what is a difficult environment, with limited asepsis and adding delay to transfer for definitive hospital care. In most environments drain insertion should not be performed, rather the patient should be taken to hospital as quickly as possible for chest drain insertion there. e.g. Suspected simple pneumothorax with no respiratory embarrassment is not an indication for chest drain insertion in pre-hospital care. However, in some rural areas where there are significant distances to definitive care then it may be necessary to insert a drain. Indications: The only absolute indication for a pre-hospital chest drain is chest pathology causing significant respiratory embarrassment, with hypoxia that will be relieved by drain insertion. Examples include: Tension pneumothorax - Not responding to needle decompression Tension Pneumothorax - Re-accumulating after needle decompression Needle decompression of Tension Pneumothorax Identify 2 nd intercostal space in mid-clavicular line on affected side of chest Clean skin Insert large-bore cannula just above rib in 2 nd IC space Remove needle and make sure that air either hisses from or can be aspirated from the cannula Do not occlude the cannula Watch cannula carefully to male sure it does not get occluded or kinked Note: Tension pneumothorax may be relieved sufficiently well with needle decompression alone, obviating the need for chest drain. In this circumstance the patient should be rapidly transferred to hospital under close observation.

27 Clinical Signs of Tension Pneumothorax Trachea deviated away from affected side Absent air entry on affected side Hyper-resonance on affected side Distended neck veins Signs of pneumothorax and patient severely compromised i.e. haemodynamic and respiratory failure Obviously a chest x-ray prior to drain insertion will not be available so good clinical examination and judgement is vital. Inserting a drain pre-hospital is high risk as the procedure will be carried out in a less than adequate environment. It is important to think about the anatomy of the chest wall and its landmarks whilst exposing and positioning the patient optimally. Ensure that the site for insertion is in the safe triangle and not too low with the risks of damage to the liver and spleen. Remember that the anatomy can be even more difficult to identify in obese patients. Activity Identify the 4 th or 5 th intercostal space in the anterior axillary line on yourself or a colleague and reflect on your findings Note: the 4 th and 5 th intercostal spaces are higher than you think they will be and normally lie just below axillary fold Try to maintain asepsis as much as possible, although the compromise may be an antiseptic skin spray such as BETADINE, sterile gloves and a dressing pack. Ensure that a trained paramedic or similar practitioner is able to assist with the procedure. Always make sure that the drain is firmly sutured in place so it does not dislodge during transfer to hospital. The biggest pre-hospital modification is that an underwater seal drainage system will not be available. The compromise is to attach a drainage bag, similar to a urine bag, with a one-way valve that will allow blood or fluid to escape from the pleural space. Copyright Version Number: 6

28 Questions to ask yourself before inserting a prehospital chest drain? Does this need to be done and has needle decompression relieved symptoms sufficiently? Does it need to be done now or can it wait until the patient gets to hospital? Am I competent to perform this procedure? Can I identify the anatomy well enough to safely insert the drain? Is an appropriate drainage system available? Copyright Version Number: 6

29 Procedural guidelines: pre-hospital chest drain insertion An equipment list is available at Appendix I and a Procedural Checklist can be found at Appendix D. These will be of use to you during the simulated practice session. The procedure should be carried out in a well-lit environment with full resuscitation equipment. The patient should be monitored, receive oxygen and have an intravenous cannula inserted before the procedure. As well as the competent practitioner who will insert the drain there should be an assistant present who is trained in the care of chest drains. In a patient with a suspected Tension Pneumothorax needle decompression should ALWAYS be performed prior to chest drain insertion. Examine the patient and confirm clinical findings. Position patient adequately with the arm on the side on which the drain is to be inserted behind the head. Gather appropriate equipment Best Practice Statement Discard metal trochar Rationale: Risk of internal damage Source of Evidence Descriptor: BTS guidelines Identify the SAFE TRIANGLE and choose point of insertion above a rib to avoid the neurovascular bundle Infiltrate local anaesthetic (maximum 3mg/kg 20ml 1% Plain lignocaine in 70kg adult), initially by drawing up a skin bleb with an orange needle and then using a green needle to infiltrate through the soft tissues onto the rib and pleura aspirating as the needle is advanced Maintain asepsis as much as possible Clean hands with alcohol gel and don sterile gloves Open chest drain pack keeping contents sterile Clean the skin using antiseptic skin spray Make a horizontal incision where the drain is to be inserted. Ensure that this is big enough for the drain (approximately 2-3cm) and goes through all the layers of the skin only Using forceps (come with Portex frontline kit) blunt dissect through the subcutaneous tissues (open and close forceps to separate rather than cut tissues. Make sure that you dissect down onto the upper border of the rib and open the pleura (you should feel a sudden give and sometimes a hiss of air or flow of blood) Insert a finger into the pleural cavity and sweep round to make sure that the lung is not adhered to the chest wall (CAUTION if the patient has rib fractures as these may puncture your glove) Copyright Version Number: 6

30 Estimate depth of insertion by looking at the markings on the drain and distance from apex of the lung to your incision. All the holes along the length of the drain need to be within the pleural space. Insert the drain through the hole in the pleura and into the cavity; aim the drain towards the apex DO NOT LET GO OF THE DRAIN until it is safely sutured in place Attach the end of the drain onto the closed drainage bag and tubing, make sure air is draining freely Insert a stay suture and a close (mattress) suture that can be used to close the wound when the drain is removed. Make sure you use a strong suture like 1.0 silk or it may snap. Ensure that your stay suture is tight and slightly indents the drain Secure the drain to the skin using some cut swabs and SLEEK to ensure additional drain security in pre-hospital environment Dispose of all waste and sharps appropriately Record procedure details, including any complications Copyright Version Number: 6

31 On-going Care and Management of Patients With chest drains Ideally patients with chest drains in place should be managed in appropriate clinical areas (assessment units, emergency departments, critical care areas, respiratory or thoracic surgery wards) although this may not always be feasible. Nevertheless, all healthcare professionals who are going to insert, remove or care for patients with chest drains must be competent in the management of chest drains. It is important to take an evidence-based approach to chest drain care. Best Practice Statement Areas in which patients with chest drains are to be cared for should have standard chest drain observation proformas Rationale: Risk Reduction Source of Evidence: NPSA Procedural Guidelines: Chest Drain Management In the initial hours after a chest drain has been inserted checks should be performed and documented every 30 minutes. When checking a chest drain it is important to always complete the following, which should be recorded on a standard chest drain proforma. A Procedural Checklist can be found at Appendix E. This will be of use to you during the simulated practice session Wash hands, wear apron and non-sterile gloves Check Patient o Observations (ideally record on early warning observation chart to highlight changes in physiology and potential deterioration early) Temperature Pulse Blood Pressure Respiratory rate Oxygen Saturations o Check patient positioning for comfort and any analgesia requirements Check drain o Record volume and amount of any drainage. Record whether drain bubbling or swinging o Check all connections to make sure they are intact o Check underwater seal system and make sure either 3cm of water or to the marked level as per manufacturers recommendations o Check wound to ensure drain still secure and no signs of infection o Check underwater seal system is below level of chest o Check tubing to ensure it is not looped or kinked Trouble shooting and Pitfalls The following are some hints and tips to avoid the common problems associated with chest drains and to know what actions to take when problems do occur; Drain not bubbling or swinging- could be either blocked, clamped or have inadvertently fallen outcheck patient, drain, connections, tubing, GET SENIOR HELP Tubing becomes disconnected clamp drain and replace tubing Copyright Version Number: 6

32 Leakage from drain site check wound, send swab Drain bubbling ++- could be either leak from chest drain connections or persistent air leak within the lung, check patient, drain, connections, tubing, GET SENIOR HELP Sudden increased blood or fluid losses in drain GET SENIOR HELP as patient may need surgery(>1500ml stat of blood or 200ml/hour indicates need for thoracotomy) Best Practice Statement Never milk or strip chest drains Rationale: This can lead to underlying damage to the lung Source of Evidence: Marsden Never clamp a chest drain unless changing the bottle or the tubing has become disconnected (using thumb and forefinger rather than clamp avoids inadvertently leaving it on), or unless under direct supervision of a senior respiratory physician in an appropriate specialised clinical environment. An exception is that when draining a large effusion, the drain may be clamped for one hour after 1.5 L has drained to minimise risks of flash re-expansion pulmonary oedema. Drainage bottles and tubing should be replaced every hours or when volume of drainage in the bottle exceeds mls. In some specialised environments such as respiratory wards it may be necessary to apply suction to a drain, if for example a pneumothorax is failing to respond. Again this should be ordered and supervised by a respiratory physician. High volume, low pressure suction must be used, not standard wall suction as they are high pressure.

33 Procedural Guidelines: Removing a Chest Drain Chest drains should only be removed by a practitioner who is trained in the procedure. An assistant must be present to help with wound closure. The decision to remove a chest drain should only be made by a senior doctor. A Procedural Checklist can be found at Appendix F.This will be of use to you during the simulated practice session Introduce yourself to the patient. Ensure that you have the correct patient by checking name, date of birth and CHI against name band and notes Explain the procedure to the patient and obtain informed consent. Get patient to practise Valsalva manoeuvre (3 deep breaths in and out and then hold the breath at the end of the 4 th inspiration) Gather appropriate equipment and open dressing pack Ensure patient is lying comfortably with the arm on the side of the drain behind the head Administration of oral or intravenous analgesia if not contraindicated (ideally 15 minutes before the procedure) Wash hands and put on gloves and apron Remove dressing and identify stay and close sutures Isolate close suture ready to tie once drain removed Clean wound with antiseptic skin preparation such as chlorhexidine Cut the stay suture Ask the patient to perform the Valsalva manoeuvre and firmly pull out the chest drain and get your assistant to apply pressure over the wound to prevent an air leak Clean wound with antiseptic skin preparation such as chlorhexidine Tie suture to close wound, not too tightly, apply a few steristrips if necessary Apply occlusive dressing Perform repeat chest x-ray to make sure that original pathology has not recurred (normally after 1 hour) Record procedure, including any complications in the patient s notes Regularly check patient s observations and drain site in the hours after chest drain removal Best Practice Statement Copyright Version Number: 6
