Rapid Reversal of CNS-Depressant Drug Effect Prior to Brain Death Determination

Withdrawn before enrolling · Early Phase 1

Conditions studied: Brain Death, Anoxic Brain Injury, Cardiac Arrest, Sedative Intoxication, Narcotic Intoxication

In brief

Current standard of care prior to determination of brain death in subjects with suspected anoxic brain injury is to exclude complicating medical conditions that may confound clinical assessment (such as severe electrolyte, acid base, endocrine or circulatory disturbance), achieve normothermia and normal systolic blood pressure over 100 mmHg (with or without vasopressor use), exclude the presence of neuromuscular blocking agents (with the presence of a train of 4 twitches with maximal ulnar nerve stimulation) as well as to exclude the presence of CNS depressant drug effects. At the present time the latter is done by history, drug screen and allowing enough time for paralytic and sedative drugs to be metabolized and cleared from the body. Clearance is calculated by using 5 times the drug's half-life assuming normal hepatic and renal functions. Half-life can also be prolonged in subjects who have been treated with induced hypothermia. Literature search revealed articles with general guidelines and approaches to brain death, but none addressed pharmacological reversal of sedative drugs

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• Adults with cardiac arrest who may have completed targeted temperature management (hypothermia protocol) and have had no neurological recovery after 24 hours of rewarming will be enrolled. Subjects will have a suspected diagnosis of anoxic brain injury secondary to cardiac arrest, and seizures ruled out with an EEG. All subjects are expected to be unable to consent and consent will be obtained from their legal authorized representative.

You may not qualify if…

• Spontaneous recovery of neurological functions, presence of seizures on EEG, individuals who are not yet adults, pregnant women and prisoners.
