电针对全麻围气管插管期血流动力学的影响

目的:观察电针内关等穴位对全麻围气管插管期血流动力学的影响.方法:选择全麻气管插管病人60例随机分成电针组(麻醉诱导前电针刺激内关、合谷、曲池、神门)和对照组各30例,两组病人均用咪唑安定、芬太尼、异丙酚、琥珀酰胆碱等全身麻醉药物诱导,光导喉镜明视下行气管插管;于麻醉诱导、插管期不同时点监测血流动力学各项指标的变化.结果:麻醉诱导期电针组血流动力学各项指标相对平稳,对照组则表现为显著下降(P＜0.01).气管插管过程中,电针组各项指标较麻醉诱导前有一定升高(P＜0.05),而对照组则呈现显著上升(P＜0.01).插管后5分钟两组各项指标恢复正常.结论:电针刺激内关等穴位可以稳定围插管期血流动力学变化,提高麻醉手术的安全性.

Effect of electroacupuncture on hemodynamics at peri-intratracheal intubation period under general anesthesia

Objective To observe effect of electroacupuncture on hemodynamics at peri-intratracheal intubation period under general anesthesia. Methods Sixty cases at peri-intratracheal intubation period under general anesthesia were randomly divided into electroacupuncture group Before anesthesia induction, electroacupuncture stimulation was given at Neiguan (PC 6), Hegu (LI 4), Quchi (LI 11), Shenmen (HT 7), and control group, 30 cases in each group. All the patients in the two groups received intratracheal intubation with light-guide laryngoscopy under general anesthesia with midazolam, fentanyl, isopropyl, succinylcholine, etc.; changes of various indexes of hemodynamics were detected at anesthesia induction and different time points of the intubation. Results At the anesthesia induction, various indexes of hemodynamics in the electroacupuncture group were relatively stable, and decreased significantly in the control group (P<0.01); during intratracheal intubation, the various indexes in the electroacupuncture group (P<0.05) and in the control group (P<0.01) increased significantly as compared with those before anesthesia induction; 5 min after intubation, the various indexes in both the two groups restored normal. Conclusion Electroacupuncture at Neiguan (PC 6) and other points can stabilize changes of hemodynamics at the intratracheal intubation and increase safety of operation under anesthesia.
