Abstract
BACKGROUND Pediatric refractory status epilepticus (RSE) often requires management with anesthetic infusions, but few data compare first-line anesthetics. This study aimed to compare the efficacy and adverse effects of midazolam and ketamine infusions as first-line anesthetics for pediatric RSE. METHODS Retrospective single-center study of consecutive study participants treated with ketamine or midazolam as the first-line anesthetic infusions for RSE at a quaternary care children's hospital from December 1, 2017, until September 15, 2021. RESULTS We identified 117 study participants (28 neonates), including 79 (68%) who received midazolam and 38 (32%) who received ketamine as the first-line anesthetic infusions. Seizures terminated more often in study participants administered ketamine (61%, 23/38) than midazolam (28%, 22/79; odds ratio [OR] 3.97, 95% confidence interval [CI] 1.76-8.98; P < 0.01). Adverse effects occurred more often in study participants administered midazolam (24%, 20/79) than ketamine (3%, 1/38; OR 12.54, 95% CI 1.61-97.43; P = 0.016). Study participants administered ketamine were younger, ketamine was used more often for children with acute symptomatic seizures, and midazolam was used more often for children with epilepsy. Multivariable logistic regression of seizure termination by first-line anesthetic infusion (ketamine or midazolam) including age at SE onset, SE etiology category, and individual seizure duration at anesthetic infusion initiation indicated seizures were more likely to terminate following ketamine than midazolam (OR 4.00, 95% CI 1.69-9.49; P = 0.002) and adverse effects were more likely following midazolam than ketamine (OR 13.41, 95% CI 1.61-111.04; P = 0.016). Survival to discharge was higher among study participants who received midazolam (82%, 65/79) than ketamine (55%, 21/38; P = 0.002), although treating clinicians did not attribute any deaths to ketamine or midazolam. CONCLUSIONS Among children and neonates with RSE, ketamine was more often followed by seizure termination and less often associated with adverse effects than midazolam when administered as the first-line anesthetic infusion. Further prospective data are needed to compare first-line anesthetics for RSE.

Abstract
Status epilepticus is one of the most common life-threatening neurological emergencies in childhood with the highest incidence in the first 5 years of life and high mortality and morbidity rates. Although it is known that a delayed treatment and a prolonged seizure can cause permanent brain damage, there is evidence that current treatments may be delayed and the medication doses administered are insufficient. Here, we summarize current knowledge on treatment of convulsive status epilepticus in childhood and propose a treatment algorithm. We performed a structured literature search via PubMed and ClinicalTrails.org and identified 35 prospective and retrospective studies on children <18 years comparing two and more treatment options for status epilepticus. The studies were divided into the commonly used treatment phases. As a first-line treatment, benzodiazepines buccal/rectal/intramuscular/intravenous are recommended. For status epilepticus treated with benzodiazepine refractory, no superiority of fosphenytoin, levetirazetam, or phenobarbital was identified. There is limited data on third-line treatments for refractory status epilepticus lasting >30 min. Our proposed treatment algorithm, especially for children with SE, is for in and out-of-hospital onset aids to promote the establishment and distribution of guidelines to address the treatment delay aggressively and to reduce putative permanent neuronal damage. Further studies are needed to evaluate if these algorithms decrease long-term damage and how to treat refractory status epilepticus lasting >30 min.

Abstract
OBJECTIVES To model bolus dosing, infusion rate, and weaning rate on theoretical serum concentration of midazolam and pentobarbital used in the treatment of refractory status epilepticus (RSE). DESIGN One- and two-compartment in silico pharmacokinetic models of midazolam and pentobarbital. SETTING Not applicable. SUBJECTS Not applicable. INTERVENTIONS We compared the model variables used in midazolam and pentobarbital protocols for standard RSE. MEASUREMENTS AND MAIN RESULTS Standard RSE treatment protocols result in steady-state serum concentrations that are 6.2-9.0-fold higher for the one-compartment model and 2.3-4.7-fold higher for the two-compartment model. In the model, not including bolus doses delays the achievement of serum steady-state concentration by 0.5 and 2.7 hours for midazolam and pentobarbital, respectively. Abrupt discontinuation of these medications reduces modeled medication exposure by 1.1 and 6.4 hours, respectively. CONCLUSIONS Our in silico pharmacokinetic modeling of standard midazolam and pentobarbital dosing protocols for RSE suggests potential variables to optimize in future clinical studies.

Abstract
Continuous ketamine infusions have been studied as an adjunctive agent for refractory status epilepticus (RSE) and super refractory status epilepticus (SRSE) in older children and adults. However, minimal information exists on the efficacy, safety, and dosing for continuous ketamine in young infants. We present the clinical course of 3 young infants with RSE and SRSE who received continuous ketamine in conjunction with other antiseizure medications. The condition of these patients was refractory to an average of 6 antiseizure medications before initiation of continuous ketamine infusion. For each patient, a continuous ketamine infusion was initiated at a rate of 1 mg/kg/hr with 1 patient requiring titration to a maximum of 6 mg/kg/hr. In 1 case, the concomitant use of continuous ketamine allowed for a reduction in the benzodiazepine continuous infusion rate. In all cases, ketamine was well tolerated especially in the setting of hemodynamic instability. Ketamine may provide a safe adjunct in the acute setting in severe RSE and SRSE. This is the first case series to document the use of continuous ketamine as a treatment modality in young infants with RSE or SRSE secondary to various underlying etiologies, without adverse events. Further studies are needed to evaluate the long-term safety and efficacy of continuous ketamine in this patient population.

Abstract
Abstract
Background
Pediatric status epilepticus is a neurological emergency with the potential for severe developmental and neurological consequences. Prompt diagnosis and management are necessary.
Objectives
To outline the existing best available evidence for managing pediatric and neonatal status epilepticus, in the light of emerging randomized controlled studies. We also focus on short and long-term prognoses.
Materials and methods
This is a systematic overview of the existing literature.
Results
Status epilepticus, its treatment, and prognosis are usually based on the continuation of seizure activity at 5 and 30 min. Refractory and super-refractory status epilepticus further complicates management and requires continuous EEG monitoring with regular reassessment and adjustment of therapy. Benzodiazepines have been accepted as the first line of treatment on the basis of reasonable evidence. Emerging randomized controlled trials demonstrate equal efficacy for parenterally administered phenytoin, levetiracetam, and valproic acid as second-line agents. Beyond this, the evidence for third-line options is sparse. However, encouraging evidence for midazolam and ketamine exists with further data required for immunological, dietary, and surgical interventions.
Conclusion
Our overview of the management of pediatric and neonatal status epilepticus based on available evidence emphasizes the need for evidence-based guidelines to manage status epilepticus that fails to respond to second-line treatment.

Abstract
BACKGROUND AND OBJECTIVES Few data are available regarding the use of anesthetic infusions for refractory status epilepticus (RSE) in children and neonates, and ketamine use is increasing despite limited data. We aimed to describe the impact of ketamine for RSE in children and neonates. METHODS Retrospective single-center cohort study of consecutive patients admitted to the intensive care units of a quaternary care children's hospital treated with ketamine infusion for RSE. RESULTS Sixty-nine patients were treated with a ketamine infusion for RSE. The median age at onset of RSE was 0.7 years (interquartile range 0.15-7.2), and the cohort included 13 (19%) neonates. Three patients (4%) had adverse events requiring intervention during or within 12 hours of ketamine administration, including hypertension in 2 patients and delirium in 1 patient. Ketamine infusion was followed by seizure termination in 32 patients (46%), seizure reduction in 19 patients (28%), and no change in 18 patients (26%). DISCUSSION Ketamine administration was associated with few adverse events, and seizures often terminated or improved after ketamine administration. Further data are needed comparing first-line and subsequent anesthetic medications for treatment of pediatric and neonatal RSE. CLASSIFICATION OF EVIDENCE This study provides Class IV evidence on the therapeutic utility of ketamine for treatment of RSE in children and neonates.

Abstract
Objective To discuss the results of the KETASER01 trial and the reasons for its failure, particularly in view of future studies. Methods KETASER01 is a multicenter, randomized, controlled, open‐label, sequentially designed, non‐profit Italian study that aimed to assess the efficacy of ketamine compared with conventional anesthetics in the treatment of refractory convulsive status epilepticus (RCSE) in children. Results During the 5‐year recruitment phase, a total of 76 RCSEs treated with third‐line therapy were observed in five of the 10 participating Centers; only 10 individuals (five for each study arm; five females, mean age 6.5 ± 6.3 years) were enrolled in the KETASER01 study. Two of the five patients (40%) in the experimental arm were successfully treated with ketamine and two of the five (40%) children in the control arm, where successfully treated with thiopental. In the remaining six (60%) enrolled patients, RCSE was not controlled by the randomized anesthetic(s). Significance The KETASER01 study was prematurely halted due to low eligibility of patients and no successful recruitment. No conclusions can be drawn regarding the objectives of the study. Here, we discuss the KETASER01 results and critically analyze the reasons for its failure in view of future trials.

Abstract
Status epilepticus (SE) is a frequent neurological emergency associated with high morbidity and mortality. According to the new ILAE 2015 definition, SE results either from the failure of the mechanisms responsible for seizure termination or initiation, leading to abnormally prolonged seizures. The definition has different time points for convulsive, focal and absence SE. Time is brain. There are changes in synaptic receptors leading to a more proconvulsant state and increased risk of brain lesion and sequelae with long duration. Management of SE must include three pillars: stop seizures, stabilize patients to avoid secondary lesions and treat underlying causes. Convulsive SE is defined after 5 minutes and is a major emergency. Benzodiazepines are the initial treatment, and should be given fast and an adequate dose. Phenytoin/fosphenytoin, levetiracetam and valproic acid are evidence choices for second line treatment. If SE persists, anesthetic drugs are probably the best option for third line treatment, despite lack of evidence. Midazolam is usually the best initial choice and barbiturates should be considered for refractory cases. Nonconvulsive status epilepticus has a similar initial approach, with benzodiazepines and second line intravenous (IV) agents, but after that, aggressiveness should be balanced considering risk of lesion due to seizures and medical complications caused by aggressive treatment. Usually, the best approach is the use of sequential IV antiepileptic drugs (oral/tube are options if IV options are not available). EEG monitoring is crucial for diagnosis of nonconvulsive SE, after initial control of convulsive SE and treatment control. Institutional protocols are advised to improve care.

Good seizure outcome after focal resection surgery for super-refractory status epilepticus: Report of two cases. Surg Neurol Int 2022; 13:164.

Abstract
Background: There is scarce evidence regarding focal resection surgery for super-refractory status epilepticus (SRSE), which is resistant to general anesthetic treatment over 24 h. We report two patients with SRSE, in whom good seizure outcomes were obtained following focal resection surgery. Case Description: Patient 1: A 58-year-old man who underwent left anterior temporal lobectomy with hippocampectomy at the age of 38 years after being diagnosed left medial temporal lobe epilepsy. After 19 years of surgery with no epileptic attacks, the patient developed SRSE. Electroencephalogram (EEG) demonstrated persistence of lateralized periodic discharges in the left frontotemporal region. On the 20th day after SRSE onset, resection of the frontal lobe and temporal lobe posterior to the resection cavity was performed. Patient 2: A 62-year-old man underwent craniotomy for anaplastic astrocytoma in the left frontal lobe at the age of 34 years. Since the age of 60 years, he developed SRSE 3 times over 1 and 1/12 years. On EEG, repeated ictal discharges were observed at the medial part of the left frontal region during the three SRSEs. Corresponding to the ictal EEG findings, high signals on diffusion-weighted magnetic resonance images and focal hypermetabolism on fluorodeoxyglucose-positron emission tomography were observed around the supplementary motor area, medial to the resection cavity. Resection surgery of the area was performed during the interictal period. Conclusion: Good seizure outcome was obtained in the two cases which provide additional support for the recent concept of focal resection surgery as an indication for SRSE.

Abstract
Super-refractory status epilepticus (SRSE) is a life-threatening neurological emergency with high morbidity and mortality. It is defined as “status epilepticus (SE) that continues or recurs 24 hours or more after the onset of anesthesia, including those cases in which SE recurs on the reduction or withdrawal of anesthesia.” This condition is resistant to normal protocols used in the treatment of status epilepticus and exposes patients to increased risks of neuronal death, neuronal injury, and disruption of neuronal networks if not treated in a timely manner. It is mainly seen in patients with severe acute onset brain injury or presentation of new-onset refractory status epilepticus (NORSE). The mortality, neurological deficits, and functional impairments are significant depending on the duration of status epilepticus and the resultant brain damage. Research is underway to find the cure for this devastating neurological condition. In this review, we will discuss the wide range of therapies used in the management of SRSE, provide suggestions regarding its treatment, and comment on future directions. The therapies evaluated include traditional and alternative anesthetic agents with antiepileptic agents. The other emerging therapies include hypothermia, steroids, immunosuppressive agents, electrical and magnetic stimulation therapies, emergent respective epilepsy surgery, the ketogenic diet, pyridoxine infusion, cerebrospinal fluid drainage, and magnesium infusion. To date, there is a lack of robust published data regarding the safety and effectiveness of various therapies, and there continues to be a need for large randomized multicenter trials comparing newer therapies to treat this refractory condition.

Abstract
Background One of the main challenges for paediatric palliative care (PPC) is the management of concomitant, different and severe symptoms that frequently affect the quality of life of PPC patients and are often refractory to commonly used pharmacological treatments. Consequently, many efforts are still needed to find the best therapeutic options to handle these refractory conditions. Since the first synthesis of ketamine in the 1960s, its pharmacokinetic and pharmacodynamic properties have been largely investigated and its potential wide range of clinical applications has become clear. However, this molecule still receives poor attention in some areas, including in children and PPC. This narrative review analyses the use of ketamine in children and the potential extension of its applications in PPC in order to provide new options for treatment in the PPC setting. Methods Scientific papers published before October 2020 on MEDLINE, EMBASE and the Cochrane Library were considered. The cited references of the selected papers and the authors’ personal collections of literature were reviewed. The terms “palliative care”, “ketamine”, “neuropathic pain”, “procedural pain”, “status epilepticus”, “refractory pain” and “child”, adding “age: birth–18 years” on a further filter were used for the search. Discussion The use of ketamine in PPC should be more widely considered due to its overall favourable safety profile and its efficacy, which are supported by an increasing number of studies, although in settings different from PPC and of mixed quality. Ketamine should be proposed according to a case-by-case evaluation and the specific diagnosis and the dosage and route of administration should be tailored to the specific needs of patients. Furthermore, there is evidence to suggest that ketamine is safe and efficacious in acute pain. These findings can prompt further research on the use of ketamine for the treatment of acute pain in PPC. Conclusion Ketamine could be a suitable option after the failure of conventional drugs in the treatment of different refractory conditions in PPC.

Abstract
Context Refractory status epilepticus (RSE) and super-refractory status epilepticus (SRSE) are neurological emergencies with considerable mortality and morbidity. In this paper, we provide an overview of causes, evaluation, treatment, and consequences of RSE and SRSE, reflecting the lack of high-quality evidence to inform therapeutic approach. Sources This is a narrative review based on personal practice and experience. Nevertheless, we searched MEDLINE (using PubMed and OvidSP vendors) and Cochrane central register of controlled trials, using appropriate keywords to incorporate recent evidence. Results Refractory status epilepticus is commonly defined as an acute convulsive seizure that fails to respond to two or more anti-seizure medications including at least one nonbenzodiazepine drug. Super-refractory status epilepticus is a status epilepticus that continues for ≥24 hours despite anesthetic treatment, or recurs on an attempted wean of the anesthetic regimen. Both can occur in patients known to have epilepsy or de novo, with increasing recognition of autoimmune and genetic causes. Electroencephalography monitoring is essential to monitor treatment response in refractory/super-refractory status epilepticus, and to diagnose non-convulsive status epilepticus. The mainstay of treatment for these disorders includes anesthetic infusions, primarily midazolam, ketamine, and pentobarbital. Dietary, immunological, and surgical treatments are viable in selected patients. Management is challenging due to multiple acute complications and long-term adverse consequences. Conclusions We have provided a synopsis of best practices for diagnosis and management of refractory/superrefractory status epilepticus and highlighted the lack of sufficient high-quality evidence to drive decision making, ending with a brief foray into avenues for future research.

Abstract
Background Midazolam delivered by continuous rate infusion (CRI) might be effective in dogs with cluster seizures (CS) or status epilepticus (SE). Objective To describe the use and safety of midazolam CRI in dogs with CS or SE. Animals One‐hundred six client‐owned dogs presenting to a veterinary teaching hospital with CS or SE. Methods Retrospective review of medical records for dogs with CS or SE treated with a midazolam CRI. Results Seventy‐nine dogs presented with CS and 27 dogs had SE. Seizure control was achieved in 82/106 dogs (77.4%) receiving a midazolam CRI. The median dose associated with seizure control was 0.3 mg/kg/h (range, 0.1‐2.5 mg/kg/h). The median duration of CRI was 25 hours (range, 2‐96 hours). Seizures were controlled in 34/40 dogs (85%) with idiopathic epilepsy, 32/43 dogs (74%) with structural epilepsy, 12/16 dogs (75%) with unknown epilepsy, and 4/7 dogs (57%) with reactive seizures (P = .20). Seizure control was achieved in 81% of dogs with CS and 67% in dogs with SE (P = .18). Dogs with idiopathic/unknown epilepsy were more likely to survive than those with structural epilepsy (87% vs 63%, P = .009). Adverse effects were reported in 24 dogs (22.6%) and were mild in all cases. Conclusions and Clinical Importance Midazolam CRI is apparently safe and might be an effective treatment in dogs with CS or SE.

Abstract
OBJECTIVE The objective of the study was to perform a systematic review and meta-analysis to evaluate the efficacy and safety of levetiracetam (LEV) or phenytoin (PHT) as second-line treatment for status epilepticus (SE). METHODS PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Latin American and Caribbean Health Sciences Literature (LILACS), Scopus, the Cochrane Database of Systematic Reviews, the Cochrane Central Register of Controlled Trials, and Google Scholar were assessed for prospective randomized trials comparing LEV with PHT as second-line treatment of SE published from inception until December 18th, 2019. The primary outcome was seizure cessation. Data were analyzed using a random-effects model. Quality analysis was performed using version 2 of the Cochrane risk-of-bias tool (RoB 2). The study protocol was registered on PROSPERO (CRD42020136417). RESULTS Nine studies with a total of 1732 patients were included. Overall, seizure cessation occurred in 657 of 887 (74%) of patients in the LEV group and 600 of 845 (71%) in the PHT group. Treatment success did not differ significantly between groups, and the relative risk (RR) was 1.05 (95% confidence interval (CI): 0.98-1.12; I2 = 53%). Six of the studies were at low risk of bias, one study had some risk, and two studies had high risk. CONCLUSIONS The use of LEV or PHT as second-line agents after benzodiazepine (BZD) for the treatment of SE was not associated with a difference in seizure cessation. Because there are minimal differences in efficacy at this time, clinicians should consider alternative factors when deciding on an antiepileptic drug (AED).

Abstract
BACKGROUND Early myoclonic encephalopathy (EME) is an epileptic syndrome that develops in neonates, commonly within 1 month of birth. The condition is characterized by irregular, partial, and asynchronous myoclonus. The seizures in EME are generally refractory to antiepileptic drugs and no effective treatment for EME has been established. We encountered a case of EME in which oral high-dose phenobarbital therapy effectively alleviated seizures. CASE REPORT A male infant developed erratic myoclonus in the face and limbs, exhibited upward gaze and facial flushing 20-30 times a day since 1 week of age. Electroencephalogram (EEG) showed a burst-suppression pattern, and considering the clinical features, EME was diagnosed. Valproate and vitamin B6 treatments were initiated; however, they were not effective. At day 58 after birth, oral high-dose phenobarbital therapy was introduced which resulted in the suppression of seizures to one or two per week and disappearance of the burst-suppression pattern on EEG. CONCLUSION Oral high-dose phenobarbital treatment may be suitable for controlling seizures in EME.

Abstract
AIM Aetiologies of first-ever convulsive seizures may be diverse, not all leading to recurrence or epilepsy diagnosis. We aimed to describe the epidemiology of first-ever convulsive seizures in children, investigating risk factors for recurrence and epilepsy diagnosis. METHOD This was a retrospective study of children presenting with a first-ever convulsive seizure to a tertiary-care paediatric emergency department (PED) in Italy, in a 12-month period (2011-2012). RESULTS One hundred and eight children (57 males, 51 females) presented to the PED for a first-ever convulsive seizure; 90.7% were 6 months to 6 years old (median age 1y 10mo, mean 2y 7mo, range 0mo-14y 4mo). Seizure duration was less than 5 minutes in 76.8%. Seizures were 'unprovoked' in 19.4% and 'provoked' in 80.6%. At 4-year follow-up, 37.9% of patients experienced recurrence and 13.6% received a diagnosis of epilepsy. Factors significantly associated with recurrence were the 'unprovoked' nature of the first seizure, multiple seizures in the first 24 hours, positive family history of febrile seizures or epilepsy, and pre-existing neurological conditions/problems. Factors significantly associated with a diagnosis of epilepsy were the 'unprovoked' nature of the first seizure, age older than 6 years, pre-existing neurological conditions/problems, and focal onset of first seizure. INTERPRETATION Children presenting to the PED with first-ever convulsive seizures represent a heterogeneous group. The identification of prognostic factors for recurrence and epilepsy diagnosis may help provide tailored counselling and follow-up. WHAT THIS PAPER ADDS Seizures were 'unprovoked' in 19.4% and 'provoked' in 80.6% of children presenting to the emergency department. At 4-year follow-up, 37.9% relapsed, and 13.6% received a diagnosis of epilepsy. 'Unprovoked' first seizure, family history of febrile seizures, and pre-existing neurological conditions were associated with recurrence. 'Unprovoked' first seizure, age younger than 6 years, and pre-existing neurological conditions were associated with epilepsy diagnosis.

Abstract
Background and Purpose There is sparsity of quality evidence for the use of drugs after first-line benzodiazepines in convulsive status epilepticus in children. The aim of the study was to compare the clinical efficacy and safety of intravenous levetiracetam versus intravenous phenytoin as second-line drugs in the management of generalized convulsive status epilepticus in children. Methods This open-label randomized controlled trial was conducted in the Emergency Department of The Children's Hospital and The Institute of Child Health, Multan, Pakistan over a period of 4 years and 6 months from January 2014 to June 2018. This study included 600 children with generalized convulsive status epilepticus: 300 in the 40 mg/kg levetiracetam group, and 300 in the 20 mg/kg phenytoin group. Cessation of a clinical seizure (seizure cessation rate) within 30 minutes after the end of drug administration was the primary outcome in this study, and the presence or absence of adverse effects was noted as the secondary outcome. Data were analyzed using SPSS (version 20.0). Results The children in the levetiracetam and phenytoin were aged 3.5±0.2 and 3.4±0.2 years (mean±SD), respectively, their seizure durations before the start of treatment were 25.1±0.6 and 23.8±0.4 minutes, and their treatment efficacies were 278/300 (92.7%) and 259/300 (83.3%). Levetiracetam was significantly more effective than phenytoin (p=0.012), with no significant difference in safety. Adverse events were observed in eight children in the phenytoin group. Conclusions Levetiracetam is significantly more effective than phenytoin for the treatment of convulsive status epilepticus in children who have failed to respond to benzodiazepines.

Abstract
Our goal was to provide comprehensive data on the effectiveness of ketamine in refractory status epilepticus (RSE) and to describe the potential consequences of long-term ketamine infusion. Ketamine, an N-methyl D-aspartate (NMDA) receptor antagonist, blocks excitatory pathways contributing to ongoing seizure. While ketamine use is standard in anaesthetic induction, no definitive protocol exists for its use in RSE, and little is known about its adverse effects in long-term, high-dose administration. We present two cases of RSE that responded rapidly to ketamine infusion, both with fatal outcomes secondary to metabolic acidosis and cardiovascular collapse. We performed a systematic review of the application and consequences of ketamine use in RSE. PubMed, Ovid, MEDLINE and PMC were searched for articles describing ketamine treatment for RSE according to a predetermined search strategy and inclusion criteria. The systematic review revealed wide discrepancies in ketamine dosing (infusion maintenance dose range 0.0075-10.5 mg/kg/hour), but good outcomes in medically managed RSE (75% of studies reported moderate or complete seizure control in adults, 62.5% in paediatrics). Additionally, literature review elucidated a potentially causal relationship between prolonged ketamine infusion and both cardiovascular and metabolic dysregulation. Ketamine is effective in RSE by antagonising excitotoxic NMDA receptors. However, there is high variability in ketamine dosing and scarce data on its safety in long-term infusion. Metabolic acidosis and haemodynamic instability associated with the use of long-term, high-dose ketamine infusions must be of concern to clinicians administering ketamine to critically ill patients.

Abstract
BACKGROUND Ketamine is an emerging third-line medication for refractory status epilepticus, a medical and neurological emergency requiring prompt and appropriate treatment. Owing to its pharmacological properties, ketamine represents a practical alternative to conventional anaesthetics. OBJECTIVE The objective of this study was to assess the efficacy and safety of ketamine to treat refractory status epilepticus in paediatric and adult populations. METHODS We conducted a literature search using the PubMed database, Cochrane Database of Systematic Reviews and ClinicalTrials.gov website. RESULTS We found no results from randomised controlled trials. The literature included 27 case reports accounting for 30 individuals and 14 case series, six of which included children. Overall, 248 individuals (29 children) with a median age of 43.5 years (range 2 months to 67 years) were treated in 12 case series whose sample size ranged from 5 to 67 patients (median 11). Regardless of the status epilepticus type, ketamine was twice as effective if administered early, with an efficacy rate as high as 64% in refractory status epilepticus lasting 3 days and dropping to 32% when the mean refractory status epilepticus duration was 26.5 days. Ketamine doses were extremely heterogeneous and did not appear to be an independent prognostic factor. Endotracheal intubation, a negative prognostic factor for status epilepticus, was unnecessary in 12 individuals (10 children), seven of whom were treated with oral ketamine for non-convulsive status epilepticus. CONCLUSIONS Although ketamine has proven to be effective in treating refractory status epilepticus, available studies are hampered by methodological limitations that prevent any firm conclusion. Results from two ongoing studies (ClinicalTrials.gov identification number: NCT02431663 and NCT03115489) and further clinical trials will hopefully confirm the better efficacy and safety profile of ketamine compared with conventional anaesthetics as third-line therapy in refractory status epilepticus, both in paediatric and adult populations.

Abstract
BACKGROUND Ongoing refractory status epilepticus is associated with significant morbidity and mortality. Therapeutic coma induction with midazolam, thiopentone, phenobarbitone or propofol is indicated when conventional antiepileptics fail to abort seizure. Of these, the most extensively studied is midazolam. Amongst the remaining three, phenobarbitone has the most favourable pharmacological profile, but has not been studied adequately, more so in the pediatric age group. The current retrospective case records analysis is an attempt to describe use of phenobarbitone coma in pediatric refractory status epilepticus. METHODS Case records of patients, admitted with status epilepticus to the pediatric inpatient services of a tertiary care teaching hospital of North India between January 2014 and December 2016 were reviewed. Those with refractory status epilepticus who failed to respond to midaolam infusion and phenobarbitone coma was used were included for analysis. RESULTS Overall, 108 children presented in status, of which 34 developed refractory status epilepticus. Of these 34, 21 responded to midazolam infusion and in 13 high dose phenobarbitone coma following a standardised protocol was used. Amongst these 13 (8 males and 5 females, median age 6 years, IQR: 2.5-9.5), 12 responded and 1 succumbed. The median time to clinical seizure resolution and desired electroencephalographic changes post phenobarbitone initiation were 16 (IQR: 12-25) and 72 h (IQR: 48-120) respectively. CONCLUSION High dose phenobarbitone appears to be an effective therapeutic modality in pediatric refractory status epilepticus. The current study provides a protocol for its use which can be validated in future studies with larger sample size.

Abstract
Refractory Status Epilepticus (RSE) not responding to any therapy and not associated with any aetiology has been termed as New Onset Refractory Status Epilepticus (NORSE). Guidelines for optimal management of cryptogenic NORSE are not clearly defined so far in the literature. Other than common medication, use of high-dose steroids, IV immune globulins and plasma exchanges in NORSE of unknown aetiology have been scarcely described. Immunomodulatory therapy like plasmapheresis is based on the fact that a pathological substance exists in the plasma that contributes to the disease process and its symptoms, which gets removed. We report a case of young female patient diagnosed as NORSE who responded to treatment with plasma exchange after becoming refractory to antiepileptic therapy and treatment with anaesthetic agents for recurrent seizers.

Abstract
Ketamine is an emerging therapy for pediatric refractory status epilepticus. The circumstances of its use, however, are understudied. The authors described pediatric refractory status epilepticus treated with ketamine from 2010 to 2014 at 45 centers using the Pediatric Hospital Inpatient System database. For comparison, they described children treated with pentobarbital. The authors estimated that 48 children received ketamine and pentobarbital for refractory status epilepticus, and 630 pentobarbital without ketamine. Those receiving only pentobarbital were median age 3 [interquartile range 0-10], and spent 30 [18-52] days in-hospital, including 17 [9-28] intensive care unit (ICU) days; 17% died. Median cost was $148 000 [81 000-241 000]. The pentobarbital-ketamine group was older (7 [2-11]) with longer hospital stays (51 [30-93]) and more ICU days (29 [20-56]); 29% died. Median cost was $298 000 [176 000-607 000]. For 71%, ketamine was given ≥1 day after pentobarbital. Ketamine cases per half-year increased from 2 to 9 ( P < .05). Ketamine is increasingly used for severe pediatric refractory status epilepticus, typically after pentobarbital. Research on its effectiveness is indicated.

Abstract
Status epilepticus and refractory status epilepticus represent some of the most complex conditions encountered in the neurological intensive care unit. Challenges in management are common as treatment options become limited and prolonged hospital courses are accompanied by complications and worsening patient outcomes. Antiepileptic drug treatments have become increasingly complex. Rational polytherapy should consider the pharmacodynamics and kinetics of medications. When seizures cannot be controlled with medical therapy, alternative treatments, including early surgical evaluation can be considered; however, evidence is limited. This review provides a brief overview of status epilepticus, and a recent update on the management of refractory status epilepticus based on evidence from the literature, evidence-based guidelines, and experiences at our institution.

Abstract
PURPOSE OF REVIEW There have been a considerable number of research articles published in the last 10 years outlining possible advances in the provision of electro-convulsive therapy (ECT) anaesthesia. This has resulted in a range of new drugs having been proposed as useful in the ECT setting. In particular, the use of adjuvant drugs that might improve outcomes to treatment has been investigated. RECENT FINDINGS There is a high level of interest in ketamine and remifentanil as agents that may alter response in ECT anaesthesia, by reducing cognitive effects, and minimizing the dose of induction agent. The numbers of patients involved in current trials have been small, and it is not possible to give a definitive answer as to the usefulness of these drugs at this stage. SUMMARY This review covers the major recent trials involving new and emerging treatments in ECT, and brings the reader up to date with state of knowledge of ECT anaesthesia and pharmacology.

Abstract
Because of the lack of studies comparing the efficacy and safety of levetiracetam and valproate before the induction of general anesthesia in the treatment of convulsive refractory status epilepticus in children, we aimed to compare the effectiveness of these antiepileptic drugs in patients with convulsive status epilepticus admitted to the Pediatric Intensive Care Unit between 2011 and 2014. Forty-six (59%) of the 78 patients received levetiracetam, and 32 (41%) received valproate for the treatment of refractory status epilepticus. The response rate was not significantly different between the 2 groups. Although no adverse event was noted in patients who received levetiracetam, 4 (12.5%) patients in the valproate group experienced liver dysfunction (P = .025). According to our results, levetiracetam and valproate may be used in the treatment of refractory status epilepticus before the induction of general anesthesia. Levetiracetam appears as effective as valproate, and also safer.

Abstract
INTRODUCTION Status epilepticus (SE) is a life-threatening neurological emergency. SE lasting longer than 120 min and not responding to first-line and second-line antiepileptic drugs is defined as 'refractory' (RCSE) and requires intensive care unit treatment. There is currently neither evidence nor consensus to guide either the optimal choice of therapy or treatment goals for RCSE, which is generally treated with coma induction using conventional anaesthetics (high dose midazolam, thiopental and/or propofol). Increasing evidence indicates that ketamine (KE), a strong N-methyl-d-aspartate glutamate receptor antagonist, may be effective in treating RCSE. We hypothesised that intravenous KE is more efficacious and safer than conventional anaesthetics in treating RCSE. METHODS AND ANALYSIS A multicentre, randomised, controlled, open-label, non-profit, sequentially designed study will be conducted to assess the efficacy of KE compared with conventional anaesthetics in the treatment of RCSE in children. 10 Italian centres/hospitals are involved in enrolling 57 patients aged 1 month to 18 years with RCSE. Primary outcome is the resolution of SE up to 24 hours after withdrawal of therapy and is updated for each patient treated according to the sequential method. ETHICS AND DISSEMINATION The study received ethical approval from the Tuscan Paediatric Ethics Committee (12/2015). The results of this study will be published in peer-reviewed journals and presented at international conferences. TRIAL REGISTRATION NUMBER NCT02431663; Pre-results.

Abstract
Seizures are a common presentation to emergency departments. Early intervention improves treatment response. Use of consensus guidelines is highly recommended to decrease drug side effects and reduce intensive care requirements. Benzodiazepines remain the mainstay of first-line treatment. Choice of drugs for second-line treatment is expanding and some important studies are currently underway to determine which of these agents has the best safety and effectiveness profile in children.

Abstract
BACKGROUND Pentobarbital is used for management of intractable seizures and for reducing elevated intracranial pressure. Dosing of pentobarbital can be aided by therapeutic drug monitoring (TDM). There is no commercially available automated assay for measurement of pentobarbital serum/plasma concentrations; consequently, chromatography-based assays are often used. METHODS Pentobarbital TDM was studied over a 14-year period at an academic medical center. 154 patients (94 adult, 60 pediatric) were identified who had pentobarbital levels ordered at least once during a hospital encounter. Chart review included patient diagnosis, indication for pentobarbital therapy, recent or concomitant medication with other barbiturates, patient disposition, organ donation, pentobarbital dosing changes, and neurosurgical procedures. Pentobarbital serum/plasma concentrations were determined on an automated clinical chemistry platform with a laboratory-developed test adapted from a urine barbiturates immunoassay. RESULTS Chart review showed therapeutic use of pentobarbital generally consistent with previously published literature. The most common errors observed involved confusion in barbiturate names (eg, mix-up of pentobarbital and phenobarbital in test ordering or in provider notes) that seemed to have minimal impact on TDM effectiveness, with pentobarbital serum/plasma concentrations generally within target ranges. The laboratory-developed pentobarbital immunoassay showed cross-reactivity with phenobarbital and butalbital that was eliminated by alkaline and heat pretreatment. The immunoassay was linear to 20 mcg/mL and correlated closely with gas chromatography-mass spectrometry measurements at a reference laboratory. CONCLUSIONS Pentobarbital TDM can be performed by immunoassay on an automated clinical chemistry platform, providing an alternative to chromatography-based methods. Confusion in barbiturate names is common, especially pentobarbital and phenobarbital.

Abstract
Non-convulsive seizures (NCS) are common among critically ill children with acute encephalopathy. Continuous electroencephalogram (CEEG) monitoring is an indispensable tool to detect NCS, which is essential to guiding management and assessing prognosis. Risk factors for NCS are highest in pediatric intensive care unit (PICU) patients with altered mental status (AMS) and a recently witnessed clinical seizure, acute changes on neuroimaging, and/or interictal abnormalities on CEEG. Screening for at least 24 hours in at risk pediatric populations is ideal, but around half of NCS may be detected within the first hour. Rapid treatment of prolonged seizures or status epilepticus is critical, as higher seizure burdens have been associated with poorer outcomes in critically ill children. This review integrates current information on critically ill children with AMS and the use of CEEGs, risk factors for NCS, duration of CEEG monitoring, and how the detection of NCS impacts management and outcomes.

Abstract
BACKGROUND AMPA receptors play an important role in the neurobiology of neonatal epilepsy. The present study evaluated the effect of talampanel, a potent and selective non-competitive antagonist of AMPA receptors, against kainic acid-induced continuous seizures (status epilepticus) and other behavioral abnormalities in neonatal rats. METHODS Kainic acid was administered at doses of 2 or 4mg/kg, ip to induce seizures and status epilepticus in postnatal 7 days old rat neonates in pre- and post-exposure studies, respectively. RESULTS Intraperitoneal administration of kainic acid (2 or 4mg/kg) resulted in forelimb/hind-limb scratching defined as automatism, continuous generalized tonic-clonic seizures with loss of righting reflex suggesting status epilepticus and tonic extension. Pre-exposure of talampanel (2.5-10mg/kg, ip) 30min before kainic acid did not affect the onset of kainic acid convulsions. Talampanel at 20mg/kg, ip delayed the commencement of tonic extension, but not status-induced by kainic acid. In contrast, talampanel (5 and 10mg/kg, ip) when administered 5min after kainic acid (4mg/kg, ip) postponed the onset of status epilepticus and tonic extension compared to vehicle treated group. Furthermore, talampanel (10mg/kg, ip) but not GYKI 52466 (20 or 50mg/kg, ip; a non-competitive AMPA/kainate receptor antagonist) stopped the ongoing status epilepticus when administered 10min after the administration of kainic acid. However, seizures re-occurred after 35.98±2.36min. CONCLUSION The present results suggested that talampanel is protective in kainic acid-induced neonatal status epilepticus model; however, the time of administration is a crucial factor in determining its effectiveness.

Abstract
OBJECTIVE The purpose of this study was to report on the efficacy and safety of intravenous ketamine (KE) in refractory convulsive status epilepticus (RCSE) in children and highlight its advantages with particular reference to avoiding endotracheal intubation. METHODS Since November 2009, we have used a protocol to treat RCSE including intravenous KE in all patients referred to the Neurology Unit of the Meyer Children's Hospital. RESULTS From November 2009 to February 2015, 13 children (7 females; age: 2 months-11 years and 5 months) received KE. Eight patients were treated once, two were treated twice, and the remaining three were treated 3 times during different RCSE episodes, for a total of 19 treatments. Most of the RCSE episodes were generalized (14/19). A malformation of cortical development was the most frequent etiology (4/13 children). Ketamine was administered from a minimum of 22 h to a maximum of 17 days, at doses ranging from 7 to 60 mcg/kg/min, obtaining a resolution of the RCSE in 14/19 episodes. Five patients received KE in lieu of conventional anesthetics, thus, avoiding endotracheal intubation. Ketamine was effective in 4 of them. Suppression-burst pattern was observed after the initial bolus of 3mg/kg in the majority of the responder RCSE episodes (10/14). CONCLUSIONS Ketamine is effective in treating RCSE and represents a practical alternative to conventional anesthetics for the treatment of RCSE. Its use avoids the pitfalls and dangers of endotracheal intubation, which is known to worsen RCSE prognosis. This article is part of a Special Issue entitled "Status Epilepticus".

Abstract
BACKGROUND A ketogenic diet has been used successfully to treat intractable epilepsy. However, the role of early intravenous initiation of ketogenic diet in the acute phase of super-refractory status epilepticus is not well-described. METHODS An intravenous ketogenic diet was administered to a boy with super-refractory status epilepticus. At 24 hours after intravenous ketogenic diet, moderate ketosis appeared, and thiamylal was successfully weaned at 70 hours after admission. RESULTS An intravenous ketogenic regimen led to subsequent ketosis and seizure control in a child with super-refractory status epilepticus. CONCLUSION Early induction of ketosis may be a novel strategy to effectively treat super-refractory status epilepticus. Although there are few data regarding the early use of intravenous ketogenic diet in the treatment of super-refractory status epilepticus, it may be considered an alternative option.

Abstract
Convulsive epileptic seizures in children represent a common cause of admission to pediatric emergency department. Data about incidence, etiology, and outcome are still lacking in literature. We retrospectively reviewed medical records of children presenting to our pediatric emergency department with convulsive seizures during a 12-month period and collected their diagnoses over the following year. In all, 182 children met the inclusion criteria, for a total of 214 visits (1.2% of all attendances, n = 24 864). Seizures lasted less than 5 minutes in 76%, 5 to 30 minutes in 20%, 30 to 60 minutes in 2%, and over 60 minutes in 2% visits ("early," "established," "refractory," convulsive status epilepticus, respectively). Incidence of "early" (seizure lasting 5-30 minutes) and "established" (seizure lasting 30-60 minutes) status epilepticus was 52/100 000/year and 7/100 000/year respectively. Most common causes were febrile seizures (56%) and remote symptomatic seizures (19%). Knowing the epidemiology of convulsive seizures in children is important to guide appropriate management and individualized follow-up.

Abstract
Acute central nervous system conditions due to hypoxic-ischemic encephalopathy, traumatic brain injury (TBI), status epilepticus, and central nervous system infection/inflammation, are a leading cause of death and disability in childhood. There is a critical need for effective neuroprotective therapies to improve outcome targeting distinct disease pathology. Fever, defined as patient temperature > 38°C, has been clearly shown to exacerbate brain injury. Therapeutic hypothermia (HT) is an intervention using targeted temperature management that has multiple mechanisms of action and robust evidence of efficacy in multiple experimental models of brain injury. Prospective clinical evidence for its neuroprotective efficacy exists in narrowly-defined populations with hypoxic-ischemic injury outside of the pediatric age range while trials comparing hypothermia to normothermia after TBI have failed to demonstrate a benefit on outcome but consistently demonstrate potential use in decreasing refractory intracranial pressure. Data in children from prospective, randomized controlled trials using different strategies of targeted temperature management for various outcomes are few but a large study examining HT versus controlled normothermia to improve neurological outcome in cardiac arrest is underway.

Abstract
Status epilepticus (SE) describes persistent or recurring seizures without a return to baseline mental status and is a common neurologic emergency. SE can occur in the context of epilepsy or may be symptomatic of a wide range of underlying etiologies. The clinician's aim is to rapidly institute care that simultaneously stabilizes the patient medically, identifies and manages any precipitant conditions, and terminates seizures. Seizure management involves "emergent" treatment with benzodiazepines followed by "urgent" therapy with other antiseizure medications. If seizures persist, then refractory SE is diagnosed and management options include additional antiseizure medications or infusions of midazolam or pentobarbital. This article reviews the management of pediatric SE and refractory SE.

Abstract
PURPOSE OF REVIEW This review discusses the management of status epilepticus in children, including both anticonvulsant medications and overall management approaches. RECENT FINDINGS Rapid management of status epilepticus is associated with a greater likelihood of seizure termination and better outcomes, yet data indicate that there are often management delays. This review discusses an overall management approach aiming to simultaneously identify and manage underlying precipitant causes, administer anticonvulsants in rapid succession until seizures have terminated, and identify and manage systemic complications. An example management pathway is provided. SUMMARY Status epilepticus is a common neurologic emergency in children and requires rapid intervention. Having a predetermined status epilepticus management pathway can expedite management.

Abstract
OBJECTIVE A systematic literature search and review of the best evidence for intensive care treatment of refractory status epilepticus in children using continuous infusion of midazolam or anesthetic agents. DESIGN MEDLINE and EMBASE search before December 2013 using key words and/or Medical Subject Headings identified English-language citations that were screened for eligibility and used if 1) the study was about high-dose benzodiazepine or anesthetic agent for children; 2) the treatment protocol was described and used for refractory status epilepticus; 3) the outcomes included seizure control; and 4) the series included at least five children. MAIN RESULTS Sixteen studies (645 patients) were identified, including midazolam (nine studies), barbiturate (four studies), and other anesthetic approaches (three studies). When midazolam was used as the initial agent for refractory status epilepticus, the rate of clinical seizure control was 76%, which was achieved on average 41 minutes after starting the infusion. When midazolam was used in conjunction with continuous electroencephalography, the time to seizure control was much longer and the mean dose required for seizure control was 10.7 μg/kg/min compared with a lower dose (2.8 μg/kg/min) in the studies not using this form of monitoring, suggesting that continuous electroencephalography provided additional targets for treatment. Barbiturates were usually used after midazolam failed and treatment was started, on average, 66 hours after refractory status epilepticus onset with the goal of electroencephalography burst suppression, which was achieved, on average, 22.6 hours later. Among patients failing midazolam, barbiturate infusion was effective in 65%. Inhaled anesthetics, ketamine, and hypothermia were generally used after prior therapy with midazolam and barbiturates had failed, usually several days after seizure onset. CONCLUSIONS The data on intensive care treatment of pediatric refractory status epilepticus are of poor quality, yet they show a hierarchy in strategies: early midazolam, then barbiturates, and then trial of other anesthetic strategies. In addition, using a solely clinical endpoint for seizure control may be missing significant seizure burden in pediatric refractory status epilepticus.

Abstract
OBJECTIVE Status epilepticus (SE) is considered a life-threatening medical emergency. First-line treatment with antiepileptic drugs (AEDs) consists of intravenous benzodiazepines followed by phenytoin. SE is considered refractory (RSE) when unresponsive to standard doses of the first two AEDs. Scarce evidence is available to support specific guidelines for the management of RSE in either adults or children. This study aimed to assess the efficacy and tolerability of intravenous (iv) lacosamide (LCM) in children affected by RSE. METHOD Children with RSE who were treated with ivLCM were included in the study. Efficacy was defined as the cessation of seizures after administration of ivLCM, with no need for any further antiepileptic drug. All patients had been unsuccessfully treated following standard protocols before ivLCM was administered. RESULTS Eleven children entered the study (mean age: 9.4 years). Etiology was symptomatic in 7 patients (63%). RSE was convulsive (focal or generalized) in 6 patients and nonconvulsive in 5. The mean initial bolus dose of LCM was 8.6 mg/kg. The drug, which was used as a fourth or later option, was effective in stopping RSE in 45% of patients, with seizures terminating within 12 h in three children. No serious adverse events attributable to LCM were reported. CONCLUSIONS LCM might be an effective and well-tolerated AED in children with RSE.

Abstract
OBJECTIVES Intravenous levetiracetam (LEV) has been shown to be effective and safe in treating adults with refractory status epilepticus (SE). We sought to investigate the efficacy and safety of intravenous LEV for pediatric patients with refractory SE. METHODS We performed a retrospective medical-record review of pediatric patients who were treated with intravenous LEV for refractory SE. Clinical information regarding age, sex, seizure type, and underlying neurological status was collected. We evaluated other anticonvulsants that were used prior to administration of intravenous LEV and assessed loading dose, response to treatment, and any adverse events from intravenous LEV administration. RESULTS Fourteen patients (8 boys and 6 girls) received intravenous LEV for the treatment of refractory SE. The mean age of the patients was 4.4 ± 5.5 years (range, 4 days to 14.6 years). Ten of the patients were neurologically healthy prior to the refractory SE, and the other 4 had been previously diagnosed with epilepsy. The mean loading dose of intravenous LEV was 26 ± 4.6 mg/kg (range, 20-30 mg/kg). Seizure termination occurred in 6 (43%) of the 14 patients. In particular, 4 (57%) of the 7 patients younger than 2 years showed seizure termination. No immediate adverse events occurred during or after infusions. CONCLUSIONS The current study demonstrated that the adjunctive use of intravenous LEV was effective and well tolerated in pediatric patients with refractory SE, even in patients younger than 2 years. Intravenous LEV should be considered as an effective and safe treatment option for refractory SE in pediatric patients.

Abstract
Status epilepticus (SE) is a common indication for neurocritical care and can be refractory to standard measures. Refractory SE (RSE) is associated with high morbidity and mortality. Unconventional therapies may be utilized in certain cases, including therapeutic hypothermia (TH), bumetanide, and the ketogenic diet. However, the literature describing the use of such therapies in RSE is limited. Details of a case of TH for RSE in an infant with malignant migrating partial seizures of infancy were obtained from the medical record. A 4-month-old child developed SE that was refractory to treatment with concurrent midazolam, phenobarbital, fosphenytoin, topiramate, levetiracetam, folinic acid, and pyridoxal-5-phosphate. This led to progressive implementation of three unconventional therapies: TH, bumetanide, and the ketogentic diet. Electrographic seizures ceased for the entirety of a 43-hour period of TH with a target rectal temperature of 33.0°C–34.0°C. No adverse effects of hypothermia were noted other than a single episode of asymptomatic hypokalemia. Seizures recurred 10 hours after rewarming was begun and did not abate with reinstitution of hypothermia. No effect was seen with administration of bumetanide. Seizures were controlled long-term within 48 hours of institution of the ketogenic diet. TH and the ketogenic diet may be effective for treating RSE in children.

[PMID: 24938144 DOI: 10.1016/j.pediatrneurol.2014.03.006] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/18/2014] [Revised: 03/05/2014] [Accepted: 03/10/2014] [Indexed: 10/25/2022]
Abstract
BACKGROUND Brain malformations represent a major cause of refractory seizures. Standardized protocols to treat status epilepticus of newborn are not available in the literature. PATIENT We present a case report of use of ketamine administered to a late preterm with Pierre Robin sequence, lissencephaly, polymicrogyria, and severe epilepsy. RESULTS The infusion of ketamine permitted resolution of status epilepticus, cardiorespiratory stabilization, and improved parental care for 15 days. No significant side effects were noted. CONCLUSION In the literature there are few studies regarding the use of ketamine for refractory status epilepticus, and only in nine of these described the use of, ketamine in children (2 months-18 years). This is the first report to document the effective use of ketamine in the newborn with status epilepticus.

Abstract
BACKGROUND Refractory status epilepticus is a prolongation of status epilepticus despite anticonvulsant therapy with two or three medications in proper doses; it is defined as malignant status epilepticus if it takes weeks or months. Intravenous immunoglobulin, high-dose steroids, magnesium infusion, pyridoxine, hypothermia, ketogenic diet, electroconvulsive therapy, and surgical therapy are the other treatment options for status epilepticus. PATIENT Our 5-year-old male patient was hospitalized at our pediatric intensive care unit because of status epilepticus secondary to meningoencephalitis. No response could be obtained with many medical and nonmedical therapies in our patient, who developed malignant status epilepticus with unknown etiology. Therapeutic plasma exchange was applied as convulsions continued. RESULT Ours is the first child for whom therapeutic plasma exchange was successfully applied because of malignant refractory status epilepticus secondary to meningoencephalitis. CONCLUSION Therapeutic plasma exchange may be a treatment option for children with refractory status epilepticus following presumed meningoencephalitis.
