Treatment of Refractory and Super-refractory Status Epilepticus. The mortality of SRSE ranges from 23-85% [2-4], and current therapies demonstrate 2015 . Full PDF Package Download Full PDF Package. The patient with status epilepticus has continuous or rapidly repeating seizures. In the setting of refractory generalized convulsive SE (GCSE), there is ample justification to use continuous infusions of highly sedating medications—usually midazolam, pentobarbital, or propofol. Super-refractory status epilepticus is a status epilepticus that continues for ³24 hours despite anesthetic treatment, or recurs on an attempted wean of the anesthetic regimen. The treatment protocol is intensive and includes benzodiazepines, anticonvulsants, and eventually anesthetics to medically induce coma when polypharmacy is exhausted 2). Most super-refractory status epilepticus patients (30/31, 96.8%) received midazolam as first choice. Super-refractory status epilepticus (SRSE) is defined as status epilepticus (SE) that continues for at least 24 hours after initiation of general anesthetic medications, including cases in which the SE recurs with reduction or withdrawal of anesthesia.1 SRSE holds a high risk of morbidity and New-Onset Super-Refractory Status Epilepticus Following Fever: More than a Case of NORSE Abstract We present the case of a healthy 32-year-old woman who came to our hospital due to fever and left otalgia. It is an uncommon but important clinical problem with high mortality and morbidity rates. The word, super-refectory is coined recently in status epilepticus (SE) when the seizures continue unabated for a day or more, despite rigorous management, leading to subsequent neuronal injury most of the times and even death. refractory and super‐refractory status epilepticus in a neurological intensive care unit: A single‐center audit of 30 patients. Refractory status epilepticus is defined as status epilepticus that continues despite treatment with benzodiazepines and one antiepileptic drug. Vagus nerve stimulation (VNS) is an FDA-approved therapy for refractory epilepsy that has been shown to decrease the frequency and severity of seizures. × . 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. Both can occur in patients known to have epilepsy or de novo, with increasing recognition of autoimmune and genetic causes. Case Presentation A 41-year-old previously healthy Korean man presented with fever and headache for four days, and altered mental status for one day. Shorvon S, Ferlisi M. The treatment of super-refractory status epilepticus: a critical review of available therapies and a clinical treatment protocol. In the phase III clinical trial in super-refractory status epilepticus (SRSE), patients aged 2 years or older are randomized to receive SAGE-547 versus placebo for a 6-day continuous infusion and non-responders are eligible for a 6 six day continuous infusion of open label high dose SAGE-547 infusion. In the setting of refractory generalized convulsive SE (GCSE), there is ample justification to use continuous infusions of highly sedating medications-usually midazolam, pentobarbital, or propofol. It is an uncommon but important clinical problem with high mortality and morbidity rates. She subsequently developed dizziness and gait instability, opsoclonus-myoclonus syndrome, and altered level of consciousness. Both can occur in patients known to have epilepsy or de novo, with increasing recognition of autoimmune and genetic causes. Refractory and super-refractory status epilepticus (SE) are serious illnesses with a high risk of morbidity and even fatality. 4. Refractory status epilepticus (RSE) is defined as SE that continues despite administration of both benzodiazepines and an appropriately dosed second-line antiseizure drug. Many of the recommended doses or targeted therapeutic levels are higher than referenced in the literature and based upon expert opinions at NYPH. the term "super-refractory status epilepticus" (srse) was first introduced during the london-innsbruck colloquium on se held in oxford in april 2011, and was defined [5]as continuous or recurrent seizures lasting 24 h or more follow- ing initiation of anesthetic medications, including cases in which seizure control is attained after induction of … Treatment of Refractory and Super-refractory Status Epilepticus . 6.

Objective: To provide an estimate of the annual number of super-refractory status epilepticus (SRSE) cases in the US and to evaluate utilization of hospital resources by these patients. Treatment at should be monitored this stage should be guided by specialists using an MDT approach. Approximately 23% to 48% of established patients with SE progress to RSE, and 22% of patients with RSE transition to SRSE.5In some cases, SRSE may develop Disease Overview: Super-Refractory Status Epilepticus • Status epilepticus (SE) is defined as continuous seizure activity for ≥ 5 min • One-third of patients with refractory and super-refractory SE will die, and another one-third will suffer chronic neurologic or other deficits • No approved treatments for super-refractory SE at this time and super-refractory status epilepticus: a retrospective study. A short summary of . Ketamine use in the . Generally, its causes are di-vided into genetic and symptomatic status ep-ilepticus (SE); the latter, in turn, is divided into Super-refractory status epilepticus occurs when therapeu-tic coma fails to control seizures in status epilepticus.1,2 The efficacy of therapeutic coma has not been well estab-lished and it may be associated with increased hospitaliza-tion length, cost of care, and in some cases even mortality.3-5 When prolonged therapeutic coma is used, Super-refractory status epilepticus is named for those continuous un-abated ,prolonged seizure activity, despite aggressive treatment including general anesthesia, lasting more than 24 hours. Super-refractory status epilepticus (SRSE) is defined as an epileptic status that continues or recurs 24h or more after the initiation of anaesthetic therapy, including reduction or withdrawal of anaesthetic agents [1].

Treatment of Refractory and Super-refractory Status Epilepticus. Less than 50 cases, those use ketamine, have been reported in the management of pediatric SE, but its effectiveness is unknown in patients with AHC. |. Super-refractory status epilepticus is a neurological emer- gency with high potential for morbidity and mortality if not recognized early. If status epilepticus (SE) is, as is said in nearly every review article and text, Ba life-threatening neurologic emergency, ^ then refractory SE must be much more threatening - but this is not necessarily true for all types of SE. Refractory/super-refractory nonconvulsive status epilepticus (r/srNCSE) is an acute life-threatening neurocritical entity with significant morbidity. Fung E, Yau M, Yam KM.

Status epilepticus that does not respond to first-line benzodiazepines (lorazepam or diazepam) or to second-line antiepileptic drugs (phenytoin . SUPER-REFRACTORY STATUS EPILEPTICUS. 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. Laboratory studies, CSF, and brain scanning return normal. Super-refractory status epilepticus (SRSE) is a pathology, with significant morbidity and mor-tality rates (1), that affects the neuronal envi-ronment depending on the types of seizure and their duration (2). She is intubated, transferred to the neurocritical care unit (NICU), deeply sedated, and put on continuous long-term video-EEG monitoring. 5. [] Refractory and super-refractory status epilepticus (RSE and SRSE) are life-threatening conditions requiring prompt initiation of appropriate treatment to avoid permanent neurological damage and reduce morbidity and mortality. However, the classical 4:1 ketogenic ratio may not meet the nutritional needs, specifically protein for critically-ill adults. Refractory status epilepticus (RSE) is defined as status epilep- ticus (SE) persisting over 60min and resistant to treatment with benzodiazepines and non-sedating antiepileptic drugs. 7. RECENT FINDINGS Status epilepticus was previously defined as lasting for 30 minutes or longer but now is more often defined as lasting 5 minutes or . In 2015, the International Status epilepticus is a life-threatening emergency, especially if refractory.1 While immediate treatment of seizures is paramount, it is also important to estab-lish the cause. The resulting condition is known as super-refractory status epilepticus (SRSE) . Although the risk of death is low in the pediatric population, the risk of subsequent neurologic morbidity and cognitive problems is high. RSE is defined as status epilepticus that persists despite administering at least two appropriately dosed parenteral medications, including a benzodiazepine. SAGE-547 is currently also in phase III . Failure to control SE in its earlier stages leads to multiple molecular alterations in the brain such as downregulation of GABA-A and upregulation of NMDA receptors. Evaluate therapeutic strategies for super-refractory status epilepticus. Similar to RSE, no guidelines exist for the treatment of SRSE. The overall approach to SRSE should be similar to that of typical SE and RSE, with the addition of therapy not previously used up to that point. Preliminary results of the global audit of treatment of refractory status epilepticus. Evaluate factors that may affect treatment success in patients with status epilepticus. The term super-refractory status epilepticus (SRSE) refers to a re - fractory episode continuing under general anesthesia for more than 24 h.

Imagine that your 23-year-old healthy child unexpectedly has a seizure and that seizure will not stop. Ferlisi M, Hocker S, Grade M, et al. Maybe it is time to overcome our reticence to use ketamine for SRSE. Introduction Status epilepticus (SE) is a critical condition that requires prompt treatment to mini-mize long-term consequences from continuous seizure activity. Within the super-refractory status epilepticus group, status epilepticus resolution was attained with a single continuous infusion in 15 of 31 patients (48.4%), two in 10 of 31 (32.3%), and three or more in six of 31 (19.4%). There is no high 16 Pages. Neurology 2020 Sep 1. Distinguish gaps in the literature related to optimal status epilepticus treatment. INTRODUCTION: Super-refractory status epilepticus (SRSE) is defined as status epilepticus that continues or recurs 24 hours or more after the onset of anesthetic therapy, including those cases where status epilepticus recurs on the reduction or withdrawal of Super-refractory status epilepticus is defined as 'status epilepticus that continues 24 h or more after the onset of anaesthesia, including those cases in which the status epilepticus recurs on the reduction or withdrawal of anaesthesia'. Synaptic GABA A receptor (GABA A R) internalization contributes to the intractable nature of SRSE. Rosati A, De Masi S, Guerrini R. Ketamine for refractory status epilepticus: a systematic review. Robert C. Knowlton, MD, MSPH, reviewing Alkhachroum A et al. Nevertheless, continuous or intermittent seizures may persist for 24 h or more following the administration of general anesthesia or recur after its withdrawal. With sustained seizure activity, excitatory N-methyl-d-aspartate (NMDA) receptors are increasingly expressed post-synaptically. 1. Overall, 15% of status epilepticus cases admitted to the hospital become super-refractory. When status epilepticus continues despite 24 h of anaesthetic use, or when status epilepticus recurs during anaesthetic weaning, patients are considered to have super-refractory status epilepticus. 3. Choose from the following (may be used in combination): 1) Repeat burst suppression for 24-48hrs 2) Add other AEDs (consider CBZ, TOP, not listed above) 3) IV magnesium (bolus 4g, then infuse 2-6g/hr) 4) Ketamine Load w/ 1.5mg/kg IV Many of the recommended doses or targeted therapeutic levels are higher than referenced in the literature and based upon expert opinions at NYPH. Identifying the underlying etiology of RSE and SRSE can be challenging. This condition is associated with a high mortality rate of 32-50% [ 45 , 46 ]; in those patients who survive, studies have reported rates of poor . Rationale: Super-refractory status epilepticus (SRSE) is status epilepticus (SE) that continues or recurs after 24 hours or more of anesthetic therapy, including instances in which SE recurs during the reduction or withdrawal of anesthesia.SRSE is associated with high morbidity and mortality. Informed consent statement was obtained for this study. This review concentrates on the treatment of refractory generalized convulsive SE (GCSE), Between 20-30% of people with cryptogenic NORSE, including those with FIRES, do not survive the prolonged, super-refractory status epilepticus (SE), also called the acute phase, most often due to complications of being in an extended medically-induced coma, having prolonged, uncontrollable seizure activity, and/or being on a "breathing machine" . Guidelines exist for the treatment protocol is intensive and includes benzodiazepines, anticonvulsants, and super-refractory status epilepticus, Midazolam.
