Comparison of propofol with methohexital for outpatient anesthesia
Abstract:
Propofol is an intravenous anesthetic currently available for clinical investigative use. The intraoperative and postoperative effects of propofol were compared to methohexital when used as an adjuvant to nitrous oxide for outpatient anesthesia. Sixty healthy young women were randomly assigned to receive either methohexital, 1.5 mg/kg intravenously (IV), or propofol, 2.5 mg/kg IV, for induction of anesthesia. Both drugs produced transient cardiovascular and respiratory depression after induction. Maintenance of anesthesia consisted of either methohexital, 6 +/- 2 mg/min, or propofol, 7 +/- 2 mg/min (mean +/- SD) by continuous infusion in combination with nitrous oxide, 70% in oxygen. Use of a propofol infusion was associated with lower blood pressures and heart rates during maintenance. Propofol was associated with fewer side effects (e.g., hiccoughing, nausea, and vomiting) intra- and postoperatively. Recovery times for awakening, orientation, and ambulation were consistently shorter with propofol. We conclude that propofol is a useful alternative to methohexital for induction and maintenance of outpatient anesthesia.

Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...
