[PMID: 38769254 DOI: 10.1007/s12028-024-02003-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2023] [Accepted: 04/24/2024] [Indexed: 05/22/2024]
Abstract
BACKGROUND Electroconvulsive therapy (ECT) has been suggested as a treatment option for refractory status epilepticus (RSE) and super-refractory status epilepticus (SRSE). OBJECTIVE The objective of this scoping review was to conduct an extensive literature review on the role of ECT as a treatment option for RSE and SRSE. METHODS We searched Ovid MEDLINE and Scopus for journal articles from database inception until February 2024. Articles were then selected based on predetermined inclusion and exclusion criteria. RESULTS We identified five retrospective case series with 28 adult patients receiving ECT for RSE or SRSE. ECT was administered within 3-70 days (mean 20 days) after the development of SE, and the mean number of ECT courses ranged from 1 to 12 sessions for each patient. ECT was administered in fixed or titrated doses. A total of 20 out of 28 patients (71%) showed clinical improvement, with two (7%) having complete cessation of seizures. It is essential to note that given the lack of control, there could be overreporting of clinical improvement in these studies. 11 patients (39%) were reported as deceased due to causes that were not directly related to ECT treatment. Four patients (14%) reported adverse effects of ECT, including memory, concentration, and/or cognitive impairment. CONCLUSIONS There are level-4 Oxford Centre for Evidence-Based Medicine evidence and low-level Grading of Recommendations Assessment Development and Education evidence that suggest ECT as a treatment option for RSE and SRSE. In light of the limitations of the existing evidence, clinicians should carefully consider individual patients' clinical contexts when deciding on the appropriateness of ECT as a treatment option. Further research, including prospective studies with controlled designs, is needed to elucidate the efficacy, safety, and optimal regime of ECT in the management of RSE and SRSE.

Daniels SD, Boison D. Bipolar mania and epilepsy pathophysiology and treatment may converge in purine metabolism: A new perspective on available evidence. Neuropharmacology 2023; 241:109756. [PMID: 37820933 PMCID: PMC10841508 DOI: 10.1016/j.neuropharm.2023.109756] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2023] [Revised: 09/25/2023] [Accepted: 10/07/2023] [Indexed: 10/13/2023]
Abstract
Decreased ATPergic signaling is an increasingly recognized pathophysiology in bipolar mania disease models. In parallel, adenosine deficit is increasingly recognized in epilepsy pathophysiology. Under-recognized ATP and/or adenosine-increasing mechanisms of several antimanic and antiseizure therapies including lithium, valproate, carbamazepine, and ECT suggest a fundamental pathogenic role of adenosine deficit in bipolar mania to match the established role of adenosine deficit in epilepsy. The depletion of adenosine-derivatives within the purine cycle is expected to result in a compensatory increase in oxopurines (uric acid precursors) and secondarily increased uric acid, observed in both bipolar mania and epilepsy. Cortisol-based inhibition of purine conversion to adenosine-derivatives may be reflected in observed uric acid increases and the well-established contribution of cortisol to both bipolar mania and epilepsy pathology. Cortisol-inhibited conversion from IMP to AMP as precursor of both ATP and adenosine may represent a mechanism for treatment resistance common in both bipolar mania and epilepsy. Anti-cortisol therapies may therefore augment other treatments both in bipolar mania and epilepsy. Evidence linking (i) adenosine deficit with a decreased need for sleep, (ii) IMP/cGMP excess with compulsive hypersexuality, and (iii) guanosine excess with grandiose delusions may converge to suggest a novel theory of bipolar mania as a condition characterized by disrupted purine metabolism. The potential for disease-modification and prevention related to adenosine-mediated epigenetic changes in epilepsy may be mirrored in mania. Evaluating the purinergic effects of existing agents and validating purine dysregulation may improve diagnosis and treatment in bipolar mania and epilepsy and provide specific targets for drug development.

Abstract
OBJECTIVE We aim to describe use of electroconvulsive therapy (ECT) to treat super refractory status epilepticus (SRSE) in pregnancy and review the literature regarding utility and safety of ECT in refractory status epilepticus. BACKGROUND Status epilepticus (SE) is a commonly encountered emergency in neuro-critical care world. Pharmacotherapy of status epilepticus in pregnancy is very challenging given the effect of the majority of antiepileptic drugs (AEDs) on fetal development. Although there has been growing evidence for use of ECT in status epilepticus, data about its utility in pregnancy is lacking. DESIGN/METHOD A twenty-one year old Caucasian female with history of epilepsy presented at 8 weeks of gestation as status epilepticus (SE) after abrupt discontinuation of her AEDs. Treatment was initiated with standard regimen of benzodiazepine and levetiracetam, which was progressively expanded to include approximately 10 anti-epileptic drugs over the course of 30 days. The status epilepticus was super refractory to sedation. She underwent ECT on day 31 with remarkable improvement in electroencephalogram (EEG) pattern and resolution of status epilepticus following a single ECT session. We reviewed PubMed and collated case reports involving the use of ECT in status epilepticus with emphasis on differences in various confounding factors esp. etiology of status and age group. CONCLUSION Our case is the first reported case of ECT for successful treatment of SRSE in pregnancy. While majority AEDs pose a significant maternal and fetal risk during pregnancy, ECT could be a potential frontline therapy for SE in pregnancy.

Abstract
Background New-onset refractory status epilepticus (NORSE) and its subset of febrile infection-related epilepsy syndrome (FIRES) are devastating clinical presentations with high rates of mortality and morbidity. The recently published consensus on the treatment of these conditions includes anesthetics, antiseizure drugs, antivirals, antibiotics, and immune therapies. Despite the internationally accepted treatment, the outcome remains poor for a significant percentage of patients. Methods We conducted a systematic review of the use of neuromodulation techniques in the treatment of the acute phase of NORSE/FIRES using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Results Our search strategy brought up 74 articles of which 15 met our inclusion criteria. A total of 20 patients were treated with neuromodulation. Thirteen cases represented FIRES and in 17 cases the NORSE remained cryptogenic. Ten had electroconvulsive therapy (ECT), seven had vagal nerve stimulation (VNS), and four had deep brain stimulation (DBS); one patient had initially VNS and later DBS. Eight patients were female and nine were children. In 17 out of 20 patients, the status epilepticus was resolved after neuromodulation, while three patients died. Conclusion NORSE can have a catastrophic course and the first treatment goal should be the fastest possible termination of status epilepticus. The data presented are limited by the small number of published cases and the variability of neuromodulation protocols used. However, they show some potential clinical benefits of early neuromodulation therapy, suggesting that these techniques could be considered within the course of FIRES/NORSE.

Abstract
INTRODUCTION Status epilepticus (SE) has a mortality rate of 20 to 50%, with acute symptomatic SE having a higher risk compared to chronic SE. Electroconvulsive therapy (ECT) has been utilized for the treatment of refractory SE with a success rate estimate of 57.9%. There are no known reported cases of concomitant use of vagus nerve stimulation (VNS) and ECT for the treatment of super refractory SE (SRSE) available in the literature. CASE DESCRIPTION We present a 44-year-old female with a history of developmental delay, epilepsy, an implantable VNS for 6 years, and traumatic brain injury with subsequent hygroma who presented with progressive aphasia, declining mental status, and daily generalized seizures lasting up to 20 min. Seizures had increased from her baseline of one seizure per day controlled with topiramate 200 mg three times daily and lamotrigine 400 mg twice daily. She was diagnosed with SRSE after being intubated and placed on eight anti-epileptic drugs (AEDs) that failed to abort SE. ECT was attempted to terminate SE. Due to a prior right craniotomy with subsequent right hygroma, eight treatments of ECT were performed over three sessions using a right anterior, left temporal (RALT) and subsequently a bitemporal electrode placement. The VNS remained active throughout treatment. Various ECT dosing parameters were attempted, varying pulse width and frequency. Although ECT induced mild transient encephalographic (EEG) changes following ECT stimulations, it was unable to terminate SE. DISCUSSION This case describes various treatment strategies, constraints, and device limitations when using ECT for the treatment of SE. With wide variability in efficacy rates of ECT in the treatment of SE in the literature, successful and unsuccessful cases offer information on optimizing ECT total charge dose and parameters that yielded success. This case demonstrates an instance of ECT inefficacy in the treatment of SRSE. Here, we discuss the rationale behind the various ECT settings that were selected, and constraints arising from the antiepileptic burden, VNS, and intrinsic limitations of the ECT device itself.

Abstract
Electroconvulsive therapy (ECT) was applied for the first time in humans in 1938: after 80 years, it remains conceptually similar today except for modifications of the original protocol aimed to reduce adverse effects (as persistent memory deficits) without losing clinical efficacy. We illustrate the stages of development as well as ups and downs of ECT use in the last eighty years, and the impact that it still maintains for treatment of certain psychiatric conditions. Targeted, individualized and safe noninvasive neuromodulatory interventions are now possible for many neuropsychiatric disorders thanks to repetitive transcranial magnetic stimulation (rTMS) that injects currents in the brain through electromagnetic induction, powerful enough to depolarize cortical neurons and related networks. Although ECT and rTMS differ in basic concepts, mechanisms, tolerability, side effects and acceptability, and beyond their conceptual remoteness (ECT) or proximity (rTMS) to "precision medicine" approaches, the two brain stimulation techniques may be considered as complementary rather than competing in the current treatment of certain neuropsychiatric disorders.

Abstract
AbstractThe treatment of super-refractory status epilepticus (SRSE) and prolonged SRSE rests on urgent seizure control to minimize excitotoxic cerebral damage, other forms of neurologic damage, and multiple medical complications. To date no randomized controlled trials or clear-cut guidelines are available for the management of SRSE. We reported the case of a 10-year-old previously healthy male child patient who presented with a febrile illness and new onset prolonged SRSE that became refractory to multiple antiseizure medications (ASMs). Coma induction with anesthetic agents, 14 ASMs, ketogenic diet, immunotherapy failed to completely control the SRSE in our patient. On day 22, clinical and electroencephalographic seizure control was achieved with isoflurane inhalation anesthesia, which was continued for 3 weeks but was unable to be weaned. From day 57 onwards, electroconvulsive therapy was administered (total 14 sessions that resulted in complete control of seizures). He was discharged on the 80th day.

Abstract
OBJECTIVE Standardized investigation of epileptic seizures and the postictal state may contribute to a better understanding of ictal and postictal phenomena. This comparative case study aims to assess whether electrically induced seizures in electroconvulsive therapy (ECT) show sufficient similarities with spontaneous seizures to serve as a human epilepsy model. METHODS We compared six EEG recordings, three ECT-induced seizures and three generalized tonic-clonic seizures, using quantitative electroencephalography (EEG) analyses. EEG recordings during and after ECT sessions (under general anesthesia and muscle paralysis) were collected prospectively, whereas epilepsy data were selected retrospectively. Time-frequency representations, dominant ictal frequencies, and postictal alpha-delta ratios were calculated. RESULTS In all EEG recordings, a decrease in dominant ictal frequency was observed, as well as postictal suppression. Postictal alpha-delta ratio indicated the same trend for all: a gradual increase from predominantly delta to alpha frequencies on timescales of hours after the seizure. Postictal spectral representation was similar. Muscle artifacts were absent in ECT-induced seizures and present in spontaneous seizures. Ictal amplitude was higher in epileptic than in ECT-induced seizures. Temporospectral ictal dynamics varied slightly between groups. SIGNIFICANCE We show that ictal and postictal characteristics in ECT and patients with generalized tonic-clonic seizures are essentially similar. ECT-induced seizures may be used to investigate aspects of ictal and postictal states in a highly predictable manner and well-controlled environment. This suggests that clinical and electrophysiological observations during ECT may be extrapolated to epilepsy with generalized tonic-clonic seizures.

Abstract
Super-refractory status epilepticus (SRSE) represents a neurological emergency that is characterized by a lack of response to the third line of antiepileptic treatment, including intravenous general anesthetics. It is a medical challenge with high morbidity and mortality. Electroconvulsive therapy (ECT) has been recommended as a nonpharmacologic option of treatment after other alternatives are unsuccessful. Its effect on the cessation of SRSE has been minimally investigated. The objective of this article is to analyze the effect of ECT on SRSE. For this purpose, a multidisciplinary team created a protocol based on clinical guidelines similar to those described previously by Ray et al. (2017). ECT was applied to six patients with SRSE after the failure of antiepileptic treatment and pharmacologic coma.The objective of each ECT session was to elicit a motor seizure for at least 20 s. SRSE was resolved in all patients after several days of treatment, including ECT as a therapy, without relevant adverse effects. Thus, ECT is an effective and feasible option in the treatment of SRSE, and its place in the algorithm in treatment should be studied due to the uncommon adverse effects and the noninvasive character of the therapy.

Abstract
Status epilepticus (SE) is a severe neurological condition in which epileptic activity is prolonged or recurring, and the likelihood of spontaneous seizure cessation decreases over time. Evidence on the appropriate treatment regimen in therapy-refractory cases is still sparse. Electroconvulsive therapy (ECT) is known as a last resort treatment for SE due its anticonvulsant properties mediated by an increase in seizure threshold during the course of a treatment series. We examined the effects of ECT in a 61-year-old male patient with new-onset super-refractory SE (SRSE), for whom previous extensive efforts to achieve seizure control had failed. To achieve reliable seizure inductions in ECT concomitantly with an extended anticonvulsant treatment, we established a high-intensity ECT protocol: bitemporal ECT was conducted at a double-dosage setting (200% stimulation energy; equivalent to a mean charge of 1,031 mC) including three seizure stimulations during each treatment session on consecutive days until SRSE termination. After the first course of ECT, temporary seizure cessation was reached but lasted for only several days. A second course of ECT was then initiated, using the identical regimen but followed by tapering sessions every other day. Again, the SRSE terminated and after regaining consciousness the patient could be transferred to an acute rehabilitation facility. SRSE cessation can successfully be achieved by means of high-intensity ECT even after six weeks of prolonged SE and exhausted anticonvulsant pharmacotherapeutic strategies. As controlled clinical trials in the area of SRSE are still lacking, the relative significance of a high-intensity ECT protocol in this clinical setting has yet to be determined.

Abstract
RATIONALE Refractory status epilepticus (RSE) is the persistence of status epilepticus despite second-line treatment. Super-refractory SE (SRSE) is characterized by ongoing status despite 48 h of anaesthetic treatment. Due to the high case fatality in RSE of 16-39%, off label treatments without strong evidence of efficacy in RSE are often administered. In single case-reports and small case series totalling 28 patients, acute implantation of VNS in RSE was associated with 76% and 26% success rate in generalized and focal RSE respectively. We performed an updated systematic review of the literature on efficacy of VNS in RSE/SRSE by including all reported patients. METHODS We systematically searched EMBASE, CENTRAL, Opengre.eu, and ClinicalTrials.gov, and PubMed databases to identify studies reporting the use of VNS for RSE and/or SRSE. We also searched conference abstracts from AES and ILAE meetings. RESULTS 45 patients were identified in total of which 38 were acute implantations of VNS in RSE/SRSE. Five cases had VNS implantation for epilepsia partialis continua, one for refractory electrical status epilepticus in sleep and one for acute encephalitis with refractory repetitive focal seizures. Acute VNS implantation was associated with cessation of RSE/SRSE in 74% (28/38) of acute cases. Cessation did not occur in 18% (7/38) of cases and four deaths were reported (11%); all of them due to the underlying disease and unlikely related to VNS implantation. Median duration of the RSE/SRSE episode pre and post VNS implantation was 18 days (range: 3-1680 days) and 8 days (range: 3-84 days) respectively. Positive outcomes occurred in 82% (31/38) of cases. CONCLUSION VNS can interrupt RSE and SRSE in 74% of patients; data originate from reported studies classified as level IV and the risk for reporting bias is high. Further prospective studies are warranted to investigate acute VNS in RSE and SRSE.

Abstract
BACKGROUND Electroconvulsive therapy (ECT), Vagal Nerve Stimulation (VNS), Transcranial Magnetic Stimulation (TMS) and Deep Brain Stimulation (DBS) are neuromodulation therapies that have been used to treat Status Epilepticus (SE). OBJECTIVE Review the literature about the efficacy and safety of neuromodulation therapies in SE in humans. METHODS We searched studies in PubMed, Scopus, Google Scholar and Science Direct (inception to June 2018). Four review authors independently selected the studies, extracted data and assessed the methodological quality of the studies using the recommendations of the Cochrane Handbook for Systematic Reviews of Interventions, PRISMA guidelines, Oxford and GRADE scales, and Murad et al., 2018 methodological quality and synthesis of case series and case reports. RESULTS We analyzed 27 articles (45 patients) with 4 different neuromodulation therapies. In ECT we found 80% rate of disruption of SE and 5% of adverse events was reported. Using iVNS 15/16 (93.7%) patients resolved the SE. All patients who underwent TMS and DBS aborted SE, however, 50% of patients with DBS had severe adverse events. CONCLUSIONS Case series and case reports suggest that neuromodulation therapies can abort SE in 80-100% of patients (Oxford scale and GRADE were level 4 and D) with a wide range of adverse effects, which claims for prospective studies on the relationship be-tween efficacy and safety.

Abstract
OBJECTIVES Super refractory status epilepticus (SRSE) is a stage beyond refractory status that requires general anesthesia as management. Electroconvulsive therapy (ECT) is recommended only as a potential treatment option beyond general anesthesia and after all other options have been exhausted. Its effect on aborting status has been minimally researched. We present the largest case series to our knowledge exploring the effect of ECT on SRSE. METHODS Eight adults hospitalized for SRSE received ECT in an attempt to abort status after other treatment modalities were exhausted. Electroconvulsive therapy consisted of a 504-mC (≈99.4 J) stimulus delivered bifrontotemporally with a constant 0.5-millisecond pulse width. Seizure activity during ECT was monitored visually and correlated to the single-channel recording provided by the apparatus. RESULTS There was neurotelemetry or clinical evidence of improvement within 24 hours after the full course of ECT treatment in 5 (63%) of the 8 cases. Cases that improved were given an average of 7.8 total ECT stimulations, eliciting an average of 4.2 total seizures. CONCLUSIONS Although it is difficult to determine the exact role of ECT in the improvement of 63% of our cases, we present a series of patients for whom pharmacotherapy, ketogenic diet, and general anesthesia otherwise did not produce an appreciable effect on status prior to implementation of ECT. These findings suggest that cases of SRSE may benefit from ECT administration.

Abstract
INTRODUCTION Non-convulsive status epilepticus (NCSE) is a complex and diverse condition which is often an under-recognised entity in the intensive care unit. When NCSE is identified the optimal treatment strategy is not always clear. Areas covered: This review is based on a literature review of the key literature in the field over the last 5-10 years. The articles were selected based on their importance to the field by the authors. Expert commentary: This review discusses the complex situations when a neurological consultation may occur in a critical care setting and provides an update on the latest evidence regarding the recognition of NCSE and the decision making around determining the aggressiveness of treatment. It also considers the ictal-interictal continuum of conditions which may be met with, particularly in the era of continuous EEG, and provides an approach for dealing with these. Suggestions for how the field will develop are discussed.

Abstract
In spite of the extensive application of electroconvulsive therapy (ECT), how it works remains unclear. So far, researchers have made great efforts in figuring out the mechanisms underlying the effect of ECT treatment via determining the levels of neurotransmitters and cytokines and using genetic and epigenetic tools, as well as structural and functional neuroimaging. To help address this question and provide implications for future research, relevant clinical trials and animal experiments are reviewed.

Abstract
Maintenance electroconvulsive therapy (ECT) is sometimes prescribed for refractory psychiatric conditions. We describe five patients who received maintenance ECT and developed florid temporal epileptiform abnormalities on electroencephalography (EEG) despite no history of epilepsy and normal neuroimaging. All patients had received regular ECT for at least 8 months. Three patients had clinical events consistent with epileptic seizures, and video-EEG monitoring captured electrographic seizures in two patients. After cessation of ECT the EEGs normalized in all patients, and no further clinical seizures occurred. Maintenance ECT may predispose to epilepsy with a seizure focus in the temporal lobe.

Abstract
Super-refractory status epilepticus (SRSE) is a devastating neurological condition with limited treatment options. We conducted an extensive literature search to identify and summarize the therapeutic options for SRSE. The search mainly resulted in case reports of various pharmacologic and non-pharmacologic treatments. The success rate of each of the following agents, ketamine, inhaled anesthetics, intravenous immunoglobulin G (IVIG), IV steroids, ketogenic diet, hypothermia, electroconvulsive therapy (ECT), transcranial magnetic stimulation (TMS), and vagal nerve stimulation (VNS), are discussed in greater detail. The choice of appropriate treatment options for a given patient is based on clinical presentation. This review focuses on evidence-based, pharmacotherapeutic strategies for patients in SRSE.

Abstract
We describe the case of a 17-year-old male who presented with acute onset of seizures and malignant catatonia with psychosis, agitation, and hypermetabolism, who responded to electroconvulsive therapy (ECT). Soon after he began to respond, he was diagnosed with anti-N-methyl-D-aspartate (NMDA) receptor encephalitis and then given immunosuppressive therapy. Anti-NMDA receptor encephalitis is an increasingly recognized autoimmune disorder that often presents with neuropsychiatric symptoms. The mainstays for treatment have been early diagnosis, tumor work-up and removal if found, and initiation of immunosuppressive therapy. Treatment response is often slow and residual symptoms common. In this case, ECT produced clinical stabilization before the underlying diagnosis of anti-NMDA receptor encephalitis was made and standard treatment initiated. We suggest that ECT may be highly beneficial for stabilizing life-threatening neuropsychiatric symptoms in this syndrome and should be considered as a potentially additive treatment to immunotherapy when rapid relief is sought.

Abstract
INTRODUCTION Our goal was to perform a systematic review of the literature on the use of intravenous lidocaine in adults for status epilepticus (SE) and refractory status epilepticus (RSE) to determine its impact on seizure control. METHODS All articles from MEDLINE, BIOSIS, EMBASE, Global Health, HealthStar, Scopus, Cochrane Library, the International Clinical Trials Registry Platform (inception to November 2014), and gray literature were searched. The strength of evidence was adjudicated using both the Oxford and GRADE methodology by two independent reviewers. RESULTS Overall, 13 studies were identified, with 11 manuscripts and 2 meeting abstracts. Seventy-six adult patients were treated for 82 episodes of SE/RSE. Patients had varying numbers of anti-epileptic drugs (AEDs), 1-12, on board prior to lidocaine therapy. During 69 of the 82 (84.1%) episodes of SE/RSE, phenytoin was on board. The dose regimen of lidocaine varied, with some utilizing bolus dosing alone; others utilizing a combination of bolus and infusion therapy. Overall, 70.7% of seizures responded to lidocaine, with complete cessation and greater than 50% reduction seen in 64.1% and 6.1% respectively. Patient outcomes were sparingly reported. CONCLUSIONS There currently exists level 4, GRADE C evidence to support the consideration of lidocaine for SE and RSE in the adult population. Thus there is currently weak evidence to support the use of lidocaine in this context. Further prospective studies of lidocaine administration in this setting are warranted.

Abstract
Generalized convulsive status epilepticus (GCSE) is one of the most common neurologic emergencies and can be associated with significant morbidity and mortality if not treated promptly and aggressively. Management of GCSE is staged and generally involves the use of life support measures, identification and management of underlying causes, and rapid initiation of anticonvulsants. The purpose of this article is to review and evaluate published reports regarding the treatment of impending, established, refractory, and super-refractory GCSE in pediatric patients.

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
OPINION STATEMENT Status epilepticus (SE) is a medical emergency consisting of persistent or recurring seizures without a return to baseline mental status. SE can be divided into subtypes based on seizure types and underlying etiologies. Management should be implemented rapidly and based on pre-determined care pathways. The aim is to terminate seizures while simultaneously identifying and managing precipitant conditions. Seizure management involves "emergent" treatment with benzodiazepines (lorazepam intravenously, midazolam intramuscularly, or diazepam rectally) followed by "urgent" therapy (phenytoin/fosphenytoin, phenobarbital, levetiracetam or valproate sodium). If seizures persist, "refractory" treatments include infusions of midazolam or pentobarbital. Prognosis is dependent on the underlying etiology and seizure persistence. This article reviews the current management strategies for pediatric convulsive SE.

Abstract
Status epilepticus (SE) still results in significant mortality and morbidity. Whereas mortality depends mainly on the age of the patient as well as the cause, morbidity is often due to the myriad of complications that occur during prolonged admission to an intensive care environment. Although SE is a clinical diagnosis in most cases (convulsant), its treatment requires support by continuous electroencephalographic recording to ensure cessation of potential nonconvulsive elements of SE. Treatment has recently changed to incorporate four stages and must be initiated at the earliest possible time.
