Résumé
Objective:To observe the sedation effects of midazolam on maxillofacial postoperative patients with nasotracheal intubation. Methods:40 cases were equally and randomly divided into two groups: sufentanil group (group S) and sufentanil-midazolam group(group S-M).The continuous dose was 2 ml/h. If the patients feel uncomfortable, patient controlled intravenous analgesia (PCIA) was used. To observe the changes of circulation and respiration,the changes of visual analogue scale(VAS) and Ramsay score, the patients' bucking times within 24 h and the PCIA times, patients' total satisfactory degree and the complications during postoperative analgesia were recorded. Results:There were significant decreases in VAS of two groups after postoperative analgesia 1, 4, 12, 24, 48 hours(P
