Drug treatment of status epilepticus is reviewed. Tonic-clonic, focal motor, complex partial and absence status epilepticus are discussed. In managing tonic-clonic status epilepticus one should: (1) maintain vital functions at all times, (2) identify and treat precipitating factors and (3) administer an intravenous loading dose of phenytoin sodium or phenobarbital sodium. Careful use of i.v. diazepam sometimes helps to achieve these objectives. Intravenous phenytoin sodium and phenobarbital sodium provide definitive, long-term control of tonic-clonic seizures but must be administered slowly and require time to reach peak brain concentrations. Intravenous diazepam appears to enter and exit from the brain rapidly and may control seizures while therapeutic brain concentrations of long-acting drugs are being achieved. Phenytoin, phenobarbital and diazepam should not be administered intramuscularly in treating status epilepticus. Treatment of focal motor and complex partial status epilepticus is similar to that of tonic-clonic status epilepticus, but i.v. diazepam is required less frequently and loading doses of phenytoin and phenobarbital sometimes can be given more slowly. Status epilepticus of the absence type is managed with i.v. acetazolamide sodium or diazepam. Paraldehyde, muscle relaxants, general anesthesia and lidocaine may be tried when conventional therapies fail.

Status epilepticus is a common pediatric emergency that may result in significant morbidity and mortality. This article provides a clinical update on generalized tonic-clonic status epilepticus in children and a practical approach to their initial stabilization and pharmacologic management. Only an organized approach to the initial stabilization and management of the child in status epilepticus will help prevent unnecessary complications and death.

Transient elevation of serum prolactin frequently follows generalised tonic-clonic and complex partial seizures. However, the levels of prolactin during status epilepticus are not increased above the normal range. Exhaustion of central prolactin supplies has been proposed as a possible mechanism for the absence of prolactin increase during status epilepticus. To test this hypothesis we injected intravenous metoclopramide (10 mg) in eight consecutive patients with status epilepticus. One patient had generalised tonic-clonic status epilepticus. Seven patients had EEG-verified non-convulsive status epilepticus, consisting of one typical absence status, one atypical absence status and five complex partial status epilepticus. Metoclopramide raised the mean (SD) prolactin levels at least five-fold in all patients, from 5.8 (8.0) micrograms/l to 87.0 (39.0) micrograms/l, within 60 minutes after the injection. Thus the mechanism for low prolactin values in status epilepticus is not cellular depletion of stored prolactin, but more likely an altered regulation, presumably induced by prolonged seizure activity.

During the past two decades, substantial progress has been made in the understanding of the clinical features, classification, pathophysiology, central nervous system consequences, and treatment of status epilepticus. The most commonly used drug regimens have advantages and disadvantages, and, in this review, I recommend a protocol for the treatment of status epilepticus. An important concept in the approach to patients in generalized tonic-clonic status epilepticus is that treatment should be administered within a predetermined time frame. Clinical and experimental research indicates that continuous seizure activity for longer than 60 to 90 minutes may result in irreversible brain damage. As our understanding of the basic mechanisms of neuronal function and seizure generation advances, it is expected that more specific and novel approaches to the treatment of status epilepticus will emerge.

Flunitrazepam (FZP) was administered intravenously, with success, to two patients with status epilepticus. Case 1 was a patient with a tonic-clonic status epilepticus. Intravenous phenytoin had no effect. Case 2 had minor status epilepticus. With the intravenous administration of FZP, diluted 1:10 with distilled water at a dose of 0.03 mg/kg at a slow rate, both patients were relieved of the status epilepticus. Unlike diazepam, FZP neither looks cloudy when diluted with distilled water nor causes angialgia. No disturbances in circulation or respiration occurred. Considering that FZP has a strong anticonvulsant action on status epilepticus, it can be expected to be a useful therapeutic agent for status epilepticus in infants and children.

The serum concentration of prolactin is frequently increased after single epileptic seizures and has therefore been used as a method to differentiate between hysterical attacks and epileptic seizures. We determined plasma prolactin concentrations in fifteen patients with status epilepticus. Seven patients had absence status, five complex partial and three generalised tonic-clonic status epilepticus. Prolactin levels were normal in all patients which indicates that, in contrast to single seizures, status epilepticus is not associated with an increase in serum prolactin.

We report the results of treatment of refractory generalized tonic-clonic status epilepticus in 17 adults. Of 13 patients who received high-dose phenytoin (PHT, mean dose 23.8 mg/kg), seizure control was sustained in five patients. In 12 cases, anesthetic doses of pentobarbital rapidly suppressed convulsions, but sustained control required prolonged treatment. Break-through seizures were, in most cases, explained by inadequate serum pentobarbital concentrations, although we could not establish a therapeutic range of serum concentrations. EEG monitoring is necessary to assess the therapeutic response but is not a reliable index of depth of anesthesia. Some cases developed pharmacodynamic tolerance to pentobarbital. The most serious treatment complications were cardiorespiratory, but the most common and disabling side effects, although reversible, were neurologic. Fifteen patients were discharged from the hospital in stable condition; two patients died, but not as a direct consequence of treatment. Our results suggest a very good outcome of pentobarbital anesthesia for patients in refractory status epilepticus who are a reasonable medical risk and who receive optimal medical management.

Tonic-clinic status epilepticus, which is refractory to phenobarbital, phenytoin, and diazepam, may respond readily to a continuous infusion of pentobarbital. The efficacy of pentobarbital can be monitored at the bedside by electroencephalography. We report the clinical and electroencephalographic findings of two children who developed refractory tonic-clonic status epilepticus and responded to pentobarbital.

Three pediatric patients with generalized status epilepticus unresponsive to therapy with conventional anticonvulsants were successfully treated with moderate hypothermia (30 degrees to 31 degrees C) and barbiturate coma with thiopental. All 3 patients were treated with thiopental at doses producing burst suppression or an isoelectric tracing on the EEG and thiopental and barbiturate levels were followed sequentially in the plasma. Continuous thiopental infusion rates of 5 to 55 mg/kg X h maintained burst suppression and correlated with plasma thiopental levels of 25 to 40 mg/dl. Total doses of thiopental used to obtain and maintain burst suppression ranged from 15 to 50 g over 48 to 120 h. In all 3 patients, control of the status epilepticus was obtained. Moderate hypothermia and thiopental barbiturate coma are indicated in patients with generalized tonic-clonic status epilepticus which cannot be controlled with standard anticonvulsant drug therapy. This regimen has the advantage that the patient can be managed in an ICU without the need for general anesthesia with volatile anesthetic agents.

Generalized tonic-clonic status epilepticus is a relatively common neurologic emergency. The differential diagnosis of this condition includes decerebrate spasms and hysterical seizures. Initial therapy includes establishing an airway and securing an intravenous line. Blood should be obtained for chemistries and anticonvulsant levels. Administration of anticonvulsants should not be delayed until laboratory results are obtained. Intravenous diazepam will usually stop continuous tonic-clonic seizure activity, but because of a rapid redistribution phase, it necessitates administration of a longer acting anticonvulsant such as phenytoin or phenobarbital. Intravenous phenytoin should be administered slowly at a dose of 15 mg/kg while carefully monitoring vital signs. Intravenous phenobarbital produces sedation and may cause respiratory depression. Occasionally, other anticonvulsants such as paraldehyde, lidocaine, and general anesthesia will be needed to break status epilepticus. Careful follow-up of the patient and monitoring of the anticonvulsant levels may prevent future bouts of status epilepticus.
