Comparative Study
Clonidine premedication decreases propofol consumption during bispectral index (BIS) monitored propofol-ketamine technique for office-based surgery.
Propofol-ketamine anesthesia is a room air, spontaneous ventilation (RASV), dissociative intravenous (IV) sedation technique reported to have a near-zero postoperative nausea and vomiting (PONV) rate. Clonidine premedication has been reported to control blood pressure intra- and postoperatively, as well as to reduce the requirements for hypnotic agents. The bispectral index (BIS) monitor is a reproducible, objective, observer independent, quantitative measurement of the hypnotic state. ⋯ A statistically significant reduction in propofol consumption was observed in the clonidine premedicated female elective rhytidectomy patients compared with those not receiving the clonidine. Other than modestly increased requirements for IV fluids, there were no adverse effects observed with clonidine premedication.
