The surgeries based on the outpatient department have increased recently. One of the indications of outpatient surgery is chemical peeling of the face that usually requires only deep sedation of short duration.
The purpose of this study was to evaluate the effects of ketamine and midazolam for outpatient facial chemical peeling.
Fifty-nine unpremedicated patients undergoing chemical peeling of the face were anesthetized with bolus intravenous injection of 1mg/kg of ketamine and 0.1 mg/kg of midazolam. Additional dose of ketamine(10-20mg) was given as needed. During
operation,
we observed systolic and diastolic blood pressure with noninvasive blood pressure monitor and peripheral oxygen saturation(SpO2) with pulse oximeter. All patients were allowed to breathe spontaneously without ventilatory support during the
operation.
There was no case of airway obstruction and SpO2 value was over 97% in most cases. The systolic and diastolic blood pressure and pulse rate were increased after the injection of ketamine and midazolam. And we observed the untoward effect of
anesthetics
such as the purposeless movement(6.8%), involuntary phonation(3.4%), skin rash(3.4%) and headache(1.7%). In postoperative analysis about the recall, bad dream, mood, and the degree of satisfaction of this type of anesthesia, the rate of patient's
positive acceptance was high(86.4%) and the recovery time was 58min.
We conclude that combination of intravenous ketamine and midazolam can produce satisfactory anesthesia with few complications for outpatient chemical peeling surgery of the face.
