[Application of conscious sedation with midazolam, propofol and sufentanil for patients in plastic surgery].

Abstract

OBJECTIVE:

To observe the effectiveness of conscious sedation with midazolam, propofol and sufentanil for patients in plastic surgery.

METHODS:

81 patients, scheduled for plastic surgery, were randomly selected to receive conscious sedation with midazolam 0.05 mg x kg(-1) and sufentanil 0.1 microg x kg(-1) intravenously, following by a continuous infusion of midazolam-propofol-sufentanil combination (midazolam 5 mg + propofol 200 mg + sufentanil 10 microg, a total of 23 ml). The initial infusion rate was 0.2 ml x kg(-1) x h(-1), and was adjusted (in 20% of initial infusion rate increment) to maintain OAA/S score as 11 during the operation. The patients' vital signs, discomfort and level of sedation were evaluated at 5 to 10 min intervals until the end of the surgery. The complications (i. e. anoxemia, apnea, restlessness, nausea and vomiting), anesthesia duration and drug consumption were recorded. The drug infusion was discontinued at 5 - 10 min before the end of the surgical procedure. On the first postoperative day, patients were asked to rate their satisfaction with the anesthetic management and whether they would choose to receive the same anesthetic technique if necessary in the future.

RESULTS:

The OAA/S score decreased from 20.0 +/- 0 to 11.9 +/- 2.6 after midazolam and sufentanil IV (P < 0.05), and was maintained as 10.5-11.1 during the procedure. At the end of the procedure, the OAA/S score returned to 16.0 +/- 2.2, which was also lower significantly compared with baseline value (P < 0.05). The induction of sedation produced a significant decrease in SBP and DBP (P < 0.05) and no significant changes in heart rate (P > 0.05). At the end of the procedure, SBP, DBP and HR returned to the baseline value. The anoxemia happened in 11 cases, apnea in 5 cases and restlessness in 2. No nausea and vomiting occurred. The anesthesia duration and consumption of midazolam, propofol and sufentanil were (101.1 +/- 42.5) min, (8.4 +/- 3.7) mg, (189.1 +/- 88.7) mg and (18.2 +/- 5.6) microg respectively. In an interview on the first postoperative day, 96% (78/ 81) of the patients were satisfied with their anesthesia and were willing to receive the same anesthetic technique if necessary in the future.

CONCLUSION:

Conscious sedation with midazolam, propofol and sufentanil is an effective anesthetic technique for patients in plastic surgery.
