4 Policy for the Insertion and Management of Central Venous Catheters (CVC's) AIM To promote the appropriate and, safe use of CVCs throughout the Trust. OBJECTIVES 1. To identify the need for CVC and selection of catheter type. 2. To undertake appropriate preparation prior to and during placement of CVC. 3. To document the procedure. 4. To choose a relevant dressing and renew when appropriate. 5. To safely access line when required. 6. To identify a line replacement strategy when required. This policy should be read in conjunction with the following policies, particularly: Hand Hygiene (PAT/IC 5) Safe use and disposal of sharps (PAT/IC 8) Management of inoculation injuries (PAT/IC 14) Policy for the consent to examination or treatment ( PAT/PA 2) Aseptic Non Touch technique (PAT/T 32) INTRODUCTION Bloodstream infections associated with the insertion and maintenance of CVCs are among the most dangerous complications that can occur, prolonging the period of hospitalisation, increasing the cost of care and worsening the severity of the patient s underlying ill health (Epic ). Approximately 3 in every 1000 patients in UK hospitals acquire a bloodstream infection. A third of these infections will be related to central venous catheters (EPIC ). IDENTIFY NEED FOR CVC FIGURE 1 INDICATIONS FOR CVC INSERTION (from Curtis et al 1997) THERAPEUTIC INDICATIONS Administration of Intravenous therapy Performance of Plasmapheresis Performance of Haemodialysis Measurement of CVP DIAGNOSTIC INDICATIONS To establish or confirm a diagnosis and monitor the response to treatment Page 4 of 22

5 FIGURE 2 POINTS TO CONSIDER PRIOR TO CVC INSERTION (from Dougherty 2000) 1. Will the CVC be required long or short term? 2. Is the therapy continuous or intermittent? 3. What types of drugs/therapies are being used? (e.g. blood transfusions) 4. How many lumens are required? 5. Has the patient had: - Previous surgery such as mastectomy? - Previous problems with CVC insertion? - Surgery or radiotherapy to chest or neck? - Fractures such as clavicle? 6. Does the patient have a clotting disorder? 7. Does the patient have suitable venous access? 8. What is the patient s cardio- respiratory function and are they able to lie flat? 9. Is the patient at increased risk of infection? (e.g. immunocompromised) 10. Is the patient known to be allergic to: - Local anaesthetic? - Sedation? - Dressing? - Cleaning solution? 11. Is the patient cardiovascularly stable? (e.g. pacemaker cardiac arrhythmias) A single lumen catheter should be used unless multiple ports are essential for the management of the patient. If TPN is being administered, use a single lumen (or a dedicated lumen) exclusively for that purpose. Use a tunnelled catheter or implantable vascular access device for patients in whom long-term vascular access is anticipated (>30 days). It is recommended that silver impregnated catheters are used in adults whose CVC is expected to remain in place for more than 5 days. (EPIC ). In selecting an appropriate insertion site, assess the risk for infection against the risk of mechanical complications. Latest evidence based practice is to use the subclavian as this is suggested to reduce the risk of infection of site (EPIC 2, 2007). Ultrasound guided placement is preferred but is usually only of benefit with internal jugular CVC's. Subclavian CVC may be preferable for longer- term use (easier to fix in place, more comfortable) and when tunnelled lines are being used but has a higher complication rate. Femoral veins should only be used when other routes are impossible. Consider the use of peripherally inserted catheters (PICC) as an alternative to subclavian or jugular vein catheterisation. Evidence suggests they are associated with a reduction in catheter sepsis, patient discomfort and provide reliable access (Marsden Manual 2008). Page 5 of 22

6 CATHETER INSERTION Prior to insertion of CVCs, please ensure the appropriate consent is obtained in accordance with trust policy on consent (PAT/PA 2). Ultrasound Guidance Central venous access has traditionally been achieved using the landmark methods. However, failure rates up to 35% for initial CVC insertion have been reported (NICE 2002 p2). Two-dimensional (2-D) imaging ultrasound guidance allows visualisation of the desired vein and surrounding structures before and during insertion and is the method of choice. Audioguided Doppler is not recommended as a method of vein identification. In emergency situations when ultrasound equipment and/or expertise is not immediately available, use anatomical landmark methods. Therefore, it is important that this method is taught alongside the 2-D ultrasound-guided technique (NICE 2002). Operators must be trained to use ultrasound-guided techniques. This involves acquiring the necessary manual skills, together with understanding ultrasound principles and the ability to interpret ultrasound images. Training must be carried out in accordance with the Medical Equipment Training Strategy (i.e. it is recorded on database following completion and return of the appropriate training documentation, to the Medical Equipment Department). 2-D imaging ultrasound guidance is recommended as the preferred method for insertion of CVCs into the internal jugular vein, in adults and children in elective situations. 2-D imaging ultrasound guidance should be considered in most clinical circumstances where CVC insertion is necessary either electively or in an emergency situation. It is recommended that all those involved in placing CVCs using 2-D imaging ultrasound guidance undertake appropriate training to achieve competence. Audio-guided Doppler is NOT recommended for CVC insertion. General Preparations The hands of staff are the most common vehicle by which micro-organisms are transmitted between patients and are frequently implicated as the route of transmission in outbreaks of infection (Wilson 2006 p157). The clinician/practitioner must be competent (or working under the supervision of a competent person) at CVC insertion. They should adhere to the manufacturers guidelines for the device used. Insertion should take place in a clean environment, which can be easily decontaminated. Page 6 of 22

7 Use optimum aseptic technique including a sterile gown, gloves and a large sterile drape, for the insertion of CVCs (EPIC pps39). Prior to insertion, hands must be decontaminated in accordance with the Trust s Hand Hygiene Policy (PAT/IC 5) Clean the insertion site with a 2% chlorhexidine gluconate in 70% Isopropyl alcohol solution prior to CVC insertion. Use an alcoholic povidone-iodine solution for patients with a history of chlorhexidine sensitivity. Allow the antiseptic to dry before inserting the catheter (at least 30 seconds).n.b. Aqueous Chlorhexidine Gluconate products and not alcohol or iodine based products to be used on neo-natal patients (Irving 2001). Do not apply organic solvents, e.g. acetone, ether to the skin before catheter insertion. Do not apply antimicrobial ointment to the catheter placement site prior to insertion. Ensure that all sharps are used in accordance to the Trust Policy Safe use and disposal of sharps (PAT/IC 8). Adhere to the Trust policy Management of inoculation injuries (PAT/IC 14) regarding any needlestick injuries. DOCUMENTATION The CVC insertion must be documented in the patients records, including date, time, site and clinician. To enable identification of any defective or contaminated central venous catheter, the batch number of the catheter used must be recorded. (Medicines & Healthcare products Regulatory Agency 2004). Nursing care must also be recorded and evaluated each shift. This must include exit site and condition of dressing. DRESSING AND CVC SITE CARE The aim of an intravenous dressing is to minimise the contamination of the insertion site and provide stability of the device. If a gauze dressing has been applied due to bleeding, it should be replaced by a transparent dressing as soon as possible (NICE 2003 p14). Use a sterile transparent semi-permeable polyurethane dressing to cover the catheter site. Strict hand washing must be observed at all times, i.e. before and after touching line. Replace dressing if it becomes damp, loose or soiled. Page 7 of 22

8 Skin must be cleaned using 2% Chlorhexidine in 70% Isopropyl alcohol and allowed to dry prior to new dressing being applied. OR other appropriate solution if patient has sensitivity to Chlorhexidine. Do not apply antimicrobial ointment to the CVC insertion site during routine catheter site care. Needle free access devices to be connected to lumens. These must be cleaned with 2% Chlorhexidine in 70% Isopropyl alcohol before and after accessing lines for administering infusions or injections. Replace needle free access devices after 7days. The site and connections should be inspected at least once a shift and whenever there is clinical cause for concern and findings documented (Woodrow 2002). Please see appendix 2 for CVC Line care sheet. To access the central venous device for blood sampling, flushing of line etc. follow procedural guidance in the relevant chapter of Dougherty & Lister (2008) [Marsden Book of Nursing Procedures]. Lumens in continuous or daily use do not usually require flushing to maintain patency, but a Saline-Additive-Saline method should be employed during any administration of an additive. Long-term catheters used for intermittent drug administration (such as Hickman lines) should be locked weekly with heparin, determined by local policy, such as critical care and renal areas. Contact the Trust pharmacist for advice. The use of heparin for locking lines must either be prescribed prior to administration or alternatively may be administered by a healthcare professional named on a Patient Group Direction. Prior to accessing any part of the CVC system, hands must be decontaminated in accordance with the hand hygiene policy (PAT/IC 5). Catheter hubs or needle free device should be decontaminated using 2% Chlorhexidine in 70% Isopropyl Alcohol, unless contraindicated by manufacturer s recommendation (EPIC2, 2007). Replace all tubing when the vascular access device is replaced. Replace intravenous tubing and stopcocks (for non-lipid and non-blood products) no more frequently than at 72 hour intervals, unless clinically indicated. Replace intravenous tubing used to administer lipid emulsions at the end of the infusion or within 24 hours of initiating the infusion. Page 8 of 22

9 Replace intravenous tubing used to administer blood and blood components after every second unit, after transfusion episode OR at 12 hours, whichever is sooner. (EPIC , Marsden Manual 2008). Intravenous tubing used for TPN should be changed every 24 hours. If the solution contains only glucose and amino acids, administration sets in continuous use do not need to be replaced more frequently than every 72 hours. N.B. TPN should not be administered via a peripheral cannula. CENTRAL VENOUS CATHETER REPLACEMENT When and how CVC's are replaced can influence the risk of infection (Epic ). Routine replacement of CVC's was seen as a method of preventing phlebitis and catheter-related infections (Richet et al 1990 cited by Pearson 1996). However, evidence suggests that routine replacement of CVC's without a clinical need does not reduce the rate of catheter colonisation or the rate of catheter related-bloodstream infection (Pearson 1996). Cook et al (1997) suggested that catheter replacement on an as needed basis was more beneficial in reducing infections. Methods: The CVC should be removed if the patient develops a catheter- associated infection and a new catheter inserted at another site. If infection is suspected, the catheter tip should be cultured (Wilson 2006, EPIC 2007). Guide wire-assisted catheter exchange should not be used ( EPIC ). Do not routinely replace non-tunnelled CVC's as a method to prevent catheterrelated infection. If catheter related infection is suspected, obtain blood cultures from each lumen of the CVC, together with a peripheral sample. Ensure that the origin of each set of culture samples are clearly marked (e.g. CVC sample distal lumen; peripheral sample etc). A clinical assessment for signs of infection at exit site and continue need of CVC line must be carried out daily and documented. Remove any CVC that is no longer required. N.B. Catheters should be removed according to the procedures found in Appendix 1 Page 9 of 22

11 FIGURE 4 DEFINITION OF TERMS Audio-guided Doppler This generates an audible sound from flowing venous blood when placed over the vessel. Bacteraemia Bacteria in the circulating blood. CVC Central Venous Catheter (generic includes all types of central venous catheter devices). Implantable Vascular Access Devices The catheter is totally implanted under the skin and accessed by inserting a needle through the skin into a sub-cutaneous selfsealing port (e.g. Port-a-Cath). Landmark methods This involves passing the needle along the anticipated vein using surface anatomical landmarks and knowledge of the anatomy as a guide. TPN Total parenteral nutrition. Tunnelled Catheter Once inserted into the vein, the catheter is tunnelled under the skin to exit on the chest wall, to minimise migration of ascending microorganisms (e.g. Hickman catheters) Two Dimensional (2-D) imaging ultrasound This provides a real time grey scale image of the anatomy. Page 11 of 22

12 Appendix 1a Procedure summary for removal of non-tunnelled central venous catheter: (based on Department of Critical Care Procedure and Dougherty & Lister (2008). 1. Explain the procedure to the patient. 2. Place patient in a supine position (to potentially prevent embolism). 3. Cleanse hands with alcohol rub. 4. Prepare sterile field and open supplies. 5. Using clean gloves remove old dressing and dispose in biohazard container. 6. Cleanse hands with alcohol rub 7. Discontinue and disconnect infusions 8. Inspect the area for signs of infection. If indicated swab insertion site for culture. Wash hands and put on sterile gloves. 9. Prep the catheter site with Chlorhexidine. Commence cleansing at the catheter Insertion site, moving outward, in a circular motion. Allow solution to dry. 10. Clip and remove the sutures, holding the catheter (to make sure it is completely free). 11. Instruct patient on Valsalva maneuver. N.B. Valsalva maneuver, forcible exhalation effort against a closed glottis; the resultant increase in intrathroacic pressure interferes with venous return to the heart (Taylor 1988). 12. Place sterile gauze dressing over the insertion site 13. Employing the Valsalva maneuver, using gentle traction, withdraw the catheter. If Any resistance is encountered do not force the catheter and seek senior advice. 14. Apply pressure to gauze over site, using free hand. 15. Avoid any contamination of the catheter tip during removal, if culture is to be obtained. 16. f the catheter tip is to be cultured: Have a colleague assist by cutting off 1 to 2 inches of the catheter at tip into a sterile container, using a pair of sterile scissors NOT the ones used to cut sutures. N.B. Routine line removals do not require the line tip to be sent for culture. Only send tip of line if line related sepsis is suspected. 17. As soon as the catheter is free, apply firm steady pressure to the exit site and place patient in a 45 degree sitting position. 18. Hold pressure for a minimum of 5 minutes. 19. When bleeding stops, dress the site with a sterile transparent bio-occlusive dressing (Tegaderm etc) 20. Inspect the catheter to make sure the tip was removed intact. If not inform senior staff. 21. If the site bleeds, maintain pressure for a further 15 minutes. 22. If bleeding is still present after 15 minutes of undisturbed pressure, contact senior staff. Page 12 of 22

13 Ongoing care/observation: 1. Instruct patient to: a. Avoid lifting, stooping, squatting, or any strenuous activity for hours b. Avoid getting dressing wet or soiled c. Leave dressing in place for 24 hours 2. Signs and symptoms to report: a. Bleeding. b. Shortness of breath. c. Fever. d. Swelling of the site, (face, neck, arm or groin depending on site of catheter). e. Drainage from the site. Page 13 of 22

14 Appendix 1b Procedure summary for removal of tunnelled central venous catheter: (based on Dougherty & Lister 2008) N.B. The clinician/practitioner must be competent (or working under the supervision of a competent person) in removal of tunnelled catheters. 1 Check patient s FBC and clotting profile for that day. 2 Discuss procedure with patient (explaining each step as you go). 3 Screen bed area and remove clothing down to the waist. 4 Ask patient to lie as flat as possible with their arms by their sides. 5 Identify the position of the cuff in the patient by palpation. N.B. If cuff can not be easily felt, measure 22cm up from bifurcation at the end of the catheter then palpate again. If it still cannot be felt, seek assistance from a more experienced colleague. 6 Open outer bag (of minor operation pack). Put on plastic apron. Wash hands thoroughly and dry on sterile towel (provided in the pack). 7 Accept and put on sterile gloves from assistant and assemble all necessary equipment. 8 Clean the area directly over the cuff with swabs soaked in chlorhexidine in 70% alcohol. Use a circular motion, working out from the centre directly over cuff and allow to dry. 9 Position 2 sterile towels one horizontally across the waist, the other longitudinally down the side of the patient (between yourself and the patient). 10 Inform patient when you are about to administer the local anaesthetic and with a 25G needle inject 1ml of local intradermally *directly over cuff causing a raised bleb). 11 Administer a further 1 2 ml of local subcutaneously (around the cuff site area). 12 Attach a 21G needle and inject approx 4 ml of local using 2 deeper injections (one either side of the cuff area). 13 When the local anaesthetic has taken effect, make an incision over the cuff site. This should be longitudinal and about 2cm in length ensuring it has incised both the epidermis and dermis. 14 Using small artery forceps, commence blunt dissection of tissue from around and under the cuff, placing your finger into the site, at intervals, until the cuff feels mobile. 15 Clamp a pair of artery forceps onto the cuff and lift it up and out of the incision. 16 Once the catheter is clearly visible, maintaining your grip on the cuff with the forceps, cut through the full thickness with the blade. Then pull the portion of the catheter distal to the cuff, out through the exit site. 17 Still maintaining your grip on the cuff, gently dissect away fibrous tissue from around the cuff and the first 5cm of the catheter, immediately above the catheter. 18 Once the cuff is free (still maintaining your grip on the cuff) gently and carefully peel away the thin straw-coloured tissue from the catheter with the blade, ensuring the blade is pulled away from the catheter. 19 As the last strands of fibre are separated the catheter should feel freer and the white material of the catheter should become visible. Page 14 of 22

15 20 While holding a low-lint swab to the incision site, gently pull out the catheter and apply pressure. 21 Close the incision with three sutures. Commence the first suture in the middle of the incision and insert the remaining sutures evenly on either side. 22 If there continues to be any bleeding, steri-strips can be applied across the incision over the sutures. 23 Apply a small pressure dressing and advise the patient that there may be some oozing. Renew dry dressing daily observing the site until the sutures are removed (normally after 7 days). 24 Ask the patient to rest on the bed for minutes following removal (longer may be required if the patient is prone to bleeding). 25 Document procedure in the patient s notes.
