4 Definition of Prolonged Seizure A proposed Classification of Status Epilepticus according to length of seizure: 5-30 Minutes: (OR 2 or more seizures without returning to baseline): Prolonged Seizure/Early Status Epilepticus Minutes: Established Status Epilepticus. Greater than 60 Minutes: Refractory Status Epilepticus. [Expert Opinion (E)] (Glauser,2007; Ma, 2010; NICE, 2012) Definitions Prolonged Seizure/Status Epilepticus: seizure longer than 5 minute or two or more seizures without a return of consciousness between seizures.

5 Actively Seizing For the child that is actively seizing, obtain history of all antiseizure medications given around this seizure episode to: Prevent medication overdosing Prevent medication interactions Decide where the patient belongs on the pathway e.g., the patient that is still seizing at presentation to the ED after receiving 2 doses of benzodiazepines in the field, should proceed to second-line agents after the appropriate time interval. ED: Inpatient:

6 When should treatment begin? Give immediate emergency care and treatment to children, young people and adults who have prolonged (lasting 5 minutes or more) or repeated (3 or more in an hour) convulsive seizures in the community. Serious risk of immediate and long-term morbidity and mortality if convulsive seizure is not terminated by 30 minutes and therefore treatment is required urgently. [ Low quality] (NICE, 2012) Patients arriving at the hospital with a seizure can be considered as having a prolonged seizure. A pre-hospital trial showed that time from seizure onset to initiation of treatment was inversely correlated with the percentage of patients who responded to firstline therapy. Patients receiving first-line therapy within 30 minutes had >80% response rate compared to 75% within 60 minutes and 63% within 90 minutes. [ High quality] (Ma, 2010) Drug therapy for prolonged seizure Drug therapy for prolonged seizures consists of : A first-line agent PLUS A second-line agent To Pg 2

7 Drug therapy for prolonged seizure 1 st line Benzodiazepines are first-line agents. First dose should be given at 5 minutes after start of seizure. Dose may be repeated after 10 minutes if patient still seizing. Administer intravenous lorazepam as first-line treatment in hospital in children, young people, and adults with ongoing generalized tonicclonic seizures. Administer intranasal OR buccal midazolam if unable to secure immediate IV access. [ Low quality] (NICE, 2012) Drug therapy for prolonged seizure 1 st line Administer a maximum of two doses of the first-line treatment (including pre-hospital treatment). [ Low quality] (NICE, 2012) The first dose of the patient s second-line treatment should be requisitioned from the pharmacy immediately after giving a second dose of benzodiazepine. This gives the pharmacy adequate time to prepare the medication so that it can be given on-time if the patient continues to seize.

8 Drug therapy for prolonged seizure 2 nd line Second-line therapy after benzodiazepines is fosphenytoin or phenobarbital. Fosphenytoin is preferred for patients age greater than or equal to 2 months. Cardiorespiratory and blood pressure monitoring must accompany the IV administration of Fosphenytoin. [ Very low quality] (Ma, 2010) First dose of these agents should be given at 10 minutes after the second benzodiazepine dose. Dose may be repeated after an additional 15 minutes if patient still seizing.

9 Drug therapy for prolonged seizure 2 nd line Cautions: Fosphenytoin has direct cardiac effects which can lead to arrhythmias. Hypotension, though rare, does occur with fosphenytoin. Phenobarbital can cause hypotension from its vasodilatatory and cardiodepressant effects Phenobarbital can cause profound respiratory depression.! Watch for B/P changes in patients with cardiac anomalies

10 Drug therapy for prolonged seizure At Admission Order benzodiazepine from Seizure Acute Management Firstline Orderset Order either Seizure Acute Management Second-line Orderset OR patient s customized second-line meds based on Neurology recommendations All inpatients with a significant history of seizures should have as needed doses of first-line AND second line seizure rescue agents ordered as part of their admitting orders, so that they are readily available. Some patients with a history of frequent, prolonged and /or intractable seizures may use other agents other than fosphenytoin or phenobarbital for their second-line treatment. Neurology should be consulted for these patients.

11 General measures for acute seizure Immediately: Give high-concentration oxygen Assess cardiac and respiratory function Check blood glucose levels Secure IV access in a large vein Secure airway [Expert Opinion (E)] (NICE, 2012) If patient receives a dose of benzodiazepine, continuously monitor and manage cardio respiratory function. [Expert Opinion (E)] Check blood pressure every 5 minutes during seizure, then every 10 minutes during postictal period until stable. [Expert Opinion (E)] General Measures Position child to avoid injury Cardiorespiratory support as needed SpO2; support respiration including provision of high concentration oxygen Make NPO/hold feeds while seizing Document seizure start time (consider using Code Blue Sheet) Check Care Plan / Care Coordination for individualized seizure care plan Prepare/obtain next medication Consider IV placement Seizure Continues General Measures Above plus Cardiorespiratory monitoring, blood pressure q 5 minutes Correct hypoglycemia Prepare/obtain next medication

12 Laboratory evaluation for acute seizure Anti-epileptic drug (AED) levels should be considered when a child with epilepsy on AED prophylaxis develops prolonged seizure/se. [ Low quality] (Riviello, 2006) Laboratory tests (complete blood count (CBC), serum electrolytes, blood urea nitrogen (BUN), creatinine, glucose, calcium, magnesium, or stool studies) should be considered based on individual clinical circumstances that include suggestive historic or clinical findings such as vomiting, diarrhea, dehydration, or failure to return to baseline alertness. [ Very low quality] (Riviello, 2006) Investigations Confirm clinically that it is an epileptic seizure Assess risk for infection (if fever, see also Febrile Seizure Pathway) Investigate prior medications given Investigations Physical examination and history If on antiepileptic medication: consider drug level Consider laboratory tests based on individual clinical circumstances Laboratory evaluation for acute seizure Toxicology testing may be considered in children with prolonged seizure/se, when no apparent etiology is immediately identified, as the frequency of ingestion as a diagnosis was at least 3.6%. To detect a specific ingestion, suspected because of the clinical history, it should be noted that a specific serum toxicology level is required, rather than simply urine toxicology screening. [ Very low quality] (Riviello, 2006) To Pg 2

13 Bacterial cultures for acute seizure There is insufficient data to support or refute whether blood cultures should be done on a routine basis in children in whom there is no clinical suspicion of infection. [ Very low quality] (Riviello, 2006) There is insufficient data to support or refute whether lumbar puncture should be done on a routine basis in children in whom there is no clinical suspicion of a CNS infection. [ Very low quality] (Riviello, 2006) A lumbar puncture should be performed in any child who presents with a seizure and a fever and has meningeal signs and symptoms (e.g., neck stiffness, Kernig and/or Brudzinski signs). [ Moderate quality] (AAP, 2011)

14 Assess Risk of Meningitis or Intracranial Infection A lumbar puncture should be performed in any child with seizure and a fever who is felt to be at SIGNIFICANT RISK for meningitis/intracranial infection. Specific aspects of the history or exam that might suggest meningitis or intracranial infection are outlined in the table below: [ Low quality] (Baumer, 2004; Selz, 2009; Kimia, 2010; Batra, 2011; AAP, 2011; Fetveit, 2008), [Expert Opinion (E)] (AAP, 2011; BC Guideline, 2011) More detail on this subject can be found in the Febrile Seizure Learning Module. Assess Risk of Meningitis or Intracranial Infection Children with the following HISTORICAL features have an increased risk of meningitis and lumbar puncture should be CONSIDERED: A child with at least three days of illness, seen by GP in previous 24 hours, with drowsiness at home, or vomiting at home. [ Low quality] (Baumer, 2004) An infant between 6 and 12 months of age who is considered deficient in Haemophilus influenzae type b (Hib) or Streptococcus pneumoniae immunizations (i.e., has not received scheduled immunizations as recommended) or when immunization status cannot be determined because of an increased risk of bacterial meningitis. [Expert Opinion (E)] (AAP, 2011) A child who is pretreated with antibiotics, because antibiotic treatment can mask the signs and symptoms of meningitis. [Expert Opinion (E)] (AAP, 2011) History >3 days duration of illness Seen by primary MD in previous 24 hours Drowsiness or vomiting at home Infant 6-12 months old deficient in Hib or pneumococcal vaccines or immunization status cannot be determined Pretreated with antibiotics To Pg 2

15 Assess Risk of Meningitis or Intracranial Infection Children with the following PHYSICAL EXAM features have an increased risk of meningitis and lumbar puncture should be CONSIDERED: Children with petechiae, questionable nuchal rigidity, drowsiness, convulsing on examination, weakness on examination, bulging fontanel. [ Low quality] Baumer, 2004) Some studies have suggested that abnormal neurological or mental status examinations are most predictive of meningitis/ intracranial infection: patients are described as obtunded, comatose, unresponsive, lethargic, drowsy, prolonged postictal state, agitated, combative, irritable, cranky, clingy, moaning, toxic. [ Low quality](selz, 2009; Kimia, 2010; Batra, 2011; AAP 2011) Signs of infection of the head or neck with potential for intracranial extension (such as mastoiditis, sinusitis, etc.) [Expert Opinion (E)] No evidence was found to support the suggestion that children below a certain age do not exhibit the signs of meningitis. (Baumer, 2004) Physical Signs Petechiae Questionable nuchal rigidity Drowsiness Convulsing on examination Weakness or neurological deficit on examination Signs of infection of head or neck with potential for intracranial extension (such as mastoiditis, sinusitis, etc.) Bulging fontanelle Assess Risk of Meningitis or Intracranial Infection Children with COMPLEX FEBRILE SEIZURES may have an increased risk of meningitis and lumbar puncture should be CONSIDERED There is some inconsistency in the literature regarding the approach to patients with complex febrile seizures (CFS). Two guidelines state that LP should be CONSIDERED in children with CFS. [ Low quality] (Baumer, 2004; Fetveit, 2008) One guideline RECOMMENDS lumbar puncture for all patients with CFS. [Expert Opinion (E)] (Boyle, 2011) And one guideline makes no distinction between children with CFS and children with simple febrile seizures (SFS) when assessing their risk of meningitis/intracranial infection. [Expert Opinion (E)] (BC Guideline, 2011) The PAERG systematic review looked a 4 studies from , and found that the historic pooled rate for meningitis following febrile seizure was 2.9% overall, with a rate of 2% in SFS and 9.1% in CFS. [ Low quality] (PAERG, 2002) However, recent studies in the age of Hib and Pneumococcal vaccines have shown the rate of meningitis CFS to be very low at <1%, [ Low quality] (Selz, 2009; Kimia, 2010) and similar to the rate for SFS. [ Low quality] (Trainor, 2001) Complex Features Focal Seizures Seizure duration > 15 minutes Multiple seizures in 24 hours To Pg 3

16 Assess Risk of Meningitis or Intracranial Infection Children with a previous history of febrile seizures or history of pre-existing neurological abnormality may be less likely to have meningitis or intracranial infection associated with subsequent febrile seizures. [Expert Opinion (E)] Meningitis Less Likely Prior febrile seizure Pre-existing neurological findings

17 Urgent EEG in evaluation of acute prolonged seizure Consult neurology to discuss need for emergent EEG. In adults, nonconvulsive SE (NCSE) is present in 14% of patients in whom convulsive SE is controlled but in whom consciousness remains impaired. Although nonconvulsive SE occurs in children who present with prolonged seizure/se, there is insufficient data to support or refute recommendations regarding whether an EEG should be obtained to establish this diagnosis. [ Very low quality] (Riviello, 2006) Investigations As above Consider EEG Consider CT An EEG may be considered in a child presenting with prolonged seizure/se if the diagnosis of pseudostatus epilepticus is suspected. [ Low quality] (Riviello, 2006) Urgent CT in evaluation of acute prolonged seizure Emergent neuroimaging (CT) may be considered for the evaluation of the child with prolonged seizure/se if any of the following are present: o o o o o o Unknown etiology of seizure Acute change in neurologic exam from baseline Suspicion for non-accidental trauma Focal seizure onset Pre-disposing history (age <6 months, trauma, CSF shunt, malignancy, or neurocutaneous disorder). First seizure lasting > 30 minutes If neuroimaging is done, it should only be done after the child is appropriately stabilized. There is insufficient evidence to support or refute recommending routine neuroimaging. [ Low quality] (Riviello, 2006; Harden, 2007)

18 Refractory Seizure Patients are Off-Pathway Patients who continue to seize after Step 5 are OFF THE PATHWAY Further evaluation and treatment should be directed by Neurology and the Intensive Care Unit.

19 Criteria for Inpatient Admission Once seizures have resolved, the patient should continue to be monitored and observed until patient is returning to baseline. Addressing parental anxiety and providing parental education are often the key tasks of the medical team following a seizure. Criteria for Inpatient Admission ED Patients Admit Criteria Unstable cardiorespiratory or neurologic status (not returing to baseline, very somnolent) Underlying infection requiring inpatient stay Disabling parental anxiety Lack of safe home or safe transportation to home Children who are clinically unstable neurologically (e.g., not returning to baseline, very somnolent following doses of anti-seizure medications) should be admitted for observation and support. [Expert Opinion (E)] (Fetveit, 2008; Baumer, 2004) Children who present with an underlying infection requiring inpatient stay (e.g., severe pneumonia, infection requiring intravenous antibiotics) should be admitted. [Expert Opinion (E)] (BC, 2010) Children whose parents have "disabling" anxiety following the seizure episode may require admission for observation and further parental education and reassurance. [Expert Opinion (E)](BC, 2010; Fetveit, 2008) Children that lack a safe home or safe transportation home require admission and may require social work consultation. [Expert Opinion (E)] (Fetveit, 2008)

24 Answer Key 1) The correct answer is (a), non-epileptic seizures should not be treated with benzodiazepines, or other antiepileptic medications. 2) The correct answer is (e), all of the above statements are true. 3) The correct answer is (a). Ordering the Neuro Seizure Acute Management First Line Orders for all patients with a history of epileptic seizures is appropriate because one should anticipate the need for a possible seizure episode while hospitalized 4) The correct answer is (f), all of the above are true statements 5) The correct answer is (c). Cardiorespiratory monitoring is recommended when using 2nd line agents. Fosphenytoin has direct cardiac effects which can lead to arrhythmias and phenobarbital can cause hypotension from its vasodilatatory and cardiodepressant effects. 6) The correct answer is (h). All of the above are correct. 7) The correct answer is (b). A lumbar puncture should be performed in any child who presents with a seizure and a fever and has meningeal signs and symptoms (e.g., neck stiffness, Kernig and/or Brudzinski signs). 8) The correct answer is (e). All of the above statements are true. 9) The correct answer is (d). All of the above statements are true 10) The correct answer is (b). If a specific ingestion is being considered as a possible etiology of the seizure, serum toxicology testing should be ordered. Urine toxicology screening may not be sufficient.

25 Evidence Ratings We used the GRADE method of rating evidence quality. Evidence is first assessed as to whether it is from randomized trial, or observational studies. The rating is then adjusted in the following manner: Quality ratings are downgraded if studies: Have serious limitations Have inconsistent results If evidence does not directly address clinical questions If estimates are imprecise OR If it is felt that there is substantial publication bias Quality ratings can be upgraded if it is felt that: The effect size is large If studies are designed in a way that confounding would likely underreport the magnitude of the effect OR If a dose-response gradient is evident Quality of Evidence: High quality Moderate quality Low quality Very low quality Expert Opinion (E) Reference: Guyatt G et al.

28 Bibliography Search Methods, Seizures - Acute Management Studies were identified by searching electronic databases using search strategies developed and executed by a medical librarian, Jamie Graham. Searches were performed in February The following databases were searched - on the Ovid platform: Medline (2002 to date), Cochrane Database of Systematic Reviews (2005 to date; elsewhere - Embase (2002 to date), Clinical Evidence, National Guideline Clearinghouse, and TRIP. Retrieval was limited to children older than neonates and English language. In Medline and Embase, appropriate Medical Subject Headings (MeSH) and Emtree headings were used respectively, the search strategy was adapted for other databases using their controlled vocabularies, where available, along with text words. Concepts searched were status epilepticus. All retrieval was further limited to certain evidence categories, such as relevant publication types, guidelines, and index terms for study types and other similar limits.
