objective To evaluate the application of monitored anesthesia care(MAC) for patients undergoing compositive rhinoplasty. Methods 42 ASA I or II patients undergoing comprehensive rhinoplasty were performd monitored anesthesia care(MAC) with midazolam, fentanyl and propofol . The sedation maintain modified OAA/S score (Observer's Assessment of Alertness / Sedation score) of 3 or 4 . Monitor MAP, HR, RR, SpO2 and record the incidence of RR<8bpm over 60s or SpO2<90% over 30s. Record movement in response to surgery, postoperative nausea and vomiting, to assess patients' satisfaction after surgery. Results MAP, HR remained stable in the MAC management process. RR less than 8bpm over 60s in the incidence rate of 12%(5/42), SpO2 less than 90% over 30s in the incidence rate of 4.8%(2/42) . 6 patients had movement in response, to surgery, 3 female patients had postoperative nausea and vomiting. Postoperative satisfaction score was 2.4±0.6. Conclusions MAC can be used safety and effectively in comprehensive rhinoplasty and has high patient's satisfaction.
