CARDIOVASCULAR EFFECTS OF DROPERIDOL DURING ENFLURANE AND E N F L U R A N E-NITROUS OXIDE ANAESTHESIA IN MAN

DROPERIDOL is not infrequently used as an amnesic supplement and an "afterload" reducer during anaesthesia in critically ill patients because of its reported benignity on myocardial dynamics. I.z Although the cardiovascular effects of droperidol have been studied in combination with fentanyl and morphine, '-4 they have not been investigated when the drug is used during anaesthesia with potent inhalation agents. In this study we measured the cardiovascular effects of droperidol 5 mg during light steady state enflurane-oxygen and enflurane-nitrous oxideoxygen anaesthesia in 20 patients undergoing cardiac or major vascular surgery.
