The purpose of this retrospective study is to investigate the effects of conscious sedation in an outpatient setting. Data from 292 patients (154 males, 138 females), sedated for minor oral surgery, were studied using various parameters including age and sex distribution, as well as according to procedures and each drug group. Results show that this intravenous conscious sedation technique is a safe and effective method of controlling behaviour, but one has to be prepared to deal with any emergencies or complications. The specific results are as follows: 1. Most procedures (265/292) were used to Valium mixed with Demerol and Midazolam mixed with Demerol. 2. Valium revealed a high incidence of pain upon injection and symptoms limited to daily activity and thrombophlebitis. 3. Nausea and vomiting manifested in the procedure using Demerol. 4. The patient manifested comfort similar in response to the same drugs used in another treatment.
