Brief Summary:
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
Detailed Description:
Question of proposed study is whether a subject's comatose state is secondary to delayed clearance of a previously administered CNS depressant. By using pharmacologic reversal agents of commonly used benzodiazepines and opioids, the investigators aim to identify participants that may likely improve after complete clearance of the drugs from their system.
Prospective trial with enrollment of 30 subjects in 2 intensive care units at Palmetto Health Richland from January 1st 2019 to June 30th 2020. Research procedures will be performed in the intensive care setting. If participants had undergone targeted temperature management (33-36 degrees Celsius for 24 hours via intravascular or surface control methods, with or without sedation or neuromuscular blockade, followed by rewarming actively or passively at 0.25-0.5 degrees per hour over 8-12 hours to 37 degrees) investigators will wait 24 hours after rewarming prior to testing. End point is to evaluate if pharmacological reversal agents would result in improved GCS scores or return of cerebral or brainstem functions in some comatose subjects, which will be considered a positive test result.
