【摘要】：目的探讨右美托咪定静脉泵注结合七氟烷吸入诱导在宫腔镜手术麻醉中的应用价值。方法 76例手术患者随机分为两组,观察组37例于麻醉诱导前15 min按照0.5μg/kg剂量静脉泵注右美托咪定,对照组39例静脉泵注生理盐水10 ml;两组均采用七氟烷吸入诱导麻醉,比较两组患者麻醉前、意识消失时的心率(HR)、平均动脉压(MAP)情况;比较两组诱导时脑电双频谱指数(BIS)60的时间及成功插入喉罩时七氟烷浓度以及并发症情况。结果两组患者麻醉过程顺利。观察组患者意识消失时MAP无明显变化,HR低于麻醉前;对照组患者意识消失时MAP低于麻醉前,HR无明显变化。观察组诱导时BIS60的时间短于对照组(P0.01),成功插入喉罩时七氟烷浓度低于对照组(P0.01)。观察组插入喉罩时体动发生率低于对照组(P0.05)。结论右美托咪定对于宫腔镜手术麻醉效果显著,可降低插管时七氟烷吸入浓度和体动发生率,值得推广。
[Abstract]:Objective to investigate the effects of dexmedetomidine combined with intravenous infusion of seven isoflurane inhalation induced anesthesia in hysteroscopic surgery in the application value of. Methods 76 patients were randomly divided into two groups, 37 cases in observation group at 15 min before induction of anesthesia with 0.5 g/kg dose of intravenous infusion of dexmedetomidine, the control group of 39 cases of intravenous infusion 10 ml normal saline; two groups were treated with seven isoflurane inhalation anesthesia, compared two groups of patients before anesthesia, at loss of consciousness (HR) heart rate, mean arterial pressure (MAP); two group induced by bispectral index (BIS) time and success 60 insert the LMA seven halothane concentrations and complications. Results of the two groups of patients during anesthesia successfully. MAP had no obvious change in the observation group when the patients lost consciousness, HR lower than the control disappeared before anesthesia; MAP in group HR was lower than before anesthesia, the observation group had no obvious change. By the time of BIS60 is shorter than the control group (P 0.01), successfully insert the LMA seven isoflurane concentration lower than the control group (P0.01). The observation group insert the LMA body movement was lower than the control group (P0.05). Conclusion dexmedetomidine anesthesia for hysteroscopic surgery has significant effect, can reduce the intubation of seven isoflurane inhalation concentration and the incidence of body movement, and is worthy of promotion.

【正文快照】： 随着微创技术的不断更新发展,宫腔镜已逐渐代替传统开腹手术成为妇科手术的首选方案。麻醉方案的顺利实施是手术有序进行的保证,目前国内外多采用喉罩全身麻醉术,七氟烷作为常用麻醉诱导药物,较同类药物具有苏醒快的优势[1]。但研究表明,虽然七氟烷的吸入诱导可给临床医师完成
