评估右美托咪定对喉罩腹腔镜手术患者麻醉深度及苏醒质量

Evaluate of anesthesia depth and quality of awakening of dexmedetomidine on patients underwent laryngeal mask laparoscopic surgery

目的：探讨右美托咪定对喉罩腹腔镜手术患者麻醉深度及苏醒质量的影响。方法将2015年2月至2016年2月入院的80例喉罩腹腔镜手术患者随机分为两组，对照组静脉输注氯化钠注射液，实验组输注右美托咪定，比较两组患者各时段血压、心率水平、苏醒时各项恢复时间、镇痛效果与麻醉不良反应。结果实验组 T1、T3时收缩压、舒张压显著高于对照组，T4时显著低于对照组；T1～ T4心率水平低于对照组。恢复自主呼吸、睁眼、握拳时间与 VAS 评分显著低于对照组，Ramsay 评分显著高于对照组，差异均有统计学意义（P ＜0.01）；总体麻醉不良反应发生率明显低于对照组，差异有统计学意义（P ＜0.05）。结论右美托咪定对喉罩腹腔镜手术患者麻醉深度及苏醒质量影响显著，具有借鉴性。

Objective To discuss the effect of dexmedetomidine on anesthesia depth and awak-ening surgery in patients with laryngeal mask laparoscopic. Methods From February 2015 to February 2016,80 cases of laryngeal mask laparoscopic surgery were randomly divided into two groups,the control group was given intravenous infusion of sodium chloride infusion,the experiment group was given dexme-detomidine,the blood pressure at different time periods,heart rate,recovery time of recovery,analgesia effect and anesthesia adverse reactions were compared. Results SBP,DBP at T1 ,T3 in the experiment group were significantly higher than those of the control group,the SBP,DBP were significantly lower than those of the control group at T4;the recovery time of spontaneous breathing,eyes open,make fist and VAS scores in the experiment qroup were significantly lower than those in the control group,Ramsay score was significantly higher than that in the control group,the differences were significant（P 〈 0. 01）, the overall incidence of adverse reactions anesthesia in the experiment group was significantly lower than that in the control group,there were significant differences（P 〈 0. 05）. Conclusions Dexmedetomi-dine has effect on the anesthesia depth and quality of awakening of laryngeal mask laparoscopic surgery patients,and has reference.
