OBJECTIVE This trial aimed to determine whether hypotensive anaesthesia reduces blood loss during orthognathic surgery. DESIGN Randomised trial. INTERVENTION Subjects were allocated to hypotensive (24 patients) or normotensive (29 patients) groups, assigned by sealed envelope, before undergoing standard orthognathic procedure. OUTCOME MEASURE Median blood loss was measured. RESULTS A significant reduction in blood loss was seen with hypotensive anaesthesia. CONCLUSIONS There was pronounced reduction in blood loss during orthognathic procedures carried out under hypotensive anaesthesia.

正颌外科手术中的低血压麻醉和失血。

目的该试验旨在确定降压麻醉是否能减少正颌外科手术期间的失血量。设计随机试验。干预在进行标准正颌手术之前,将受试者分为低血压组(24例患者)或血压正常组(29例患者),并用密封封套进行分配。观察指标测量中位失血量。结果降压麻醉使失血量明显减少。结论在降压麻醉下进行正颌手术时,失血量明显减少。
