Prolonged recovery after intravenous diazepam

Prolonged recovery from intravenous diazepam after the day of administration has been examined in 2,468 consecutive patients who underwent oral surgery and general dentistry. Patients ranged in age from 2 to 94 years and received a mean diazepam dose of 19 mg, either by itself or with small amounts of methohexital sodium. Recovery was assessed by use of a questionnaire, and the answers were related to sexual gender, age, weight, dosage, procedure, duration, level of apprehension, and results of the sedation.
