Effect of thiopentone on emergence reactions to ketamine anaesthesia

Abstract

One hundred female patients were studied, who were premedicated with atropine alone and anaesthetized with ketamine 2.0 mg/Kg as the sole agent for minor gynaecological procedures. Fifty of these patients received thiopentone sodium 150 mg intravenously at the end of the operation. The incidence and severity of emergence reactions was significantly less in this group of patients than in the group that had no thiopentone. The dose of thiopentone employed did not produce respiratory depression. © 1974 Canadian Anesthesiologists.
