Effect of electroacupuncture on hemodynamics at peri-intratracheal intubation period under general anesthesia / 中国针灸

ABSTRACT

<p><b>OBJECTIVE</b>To observe effect of electroacupuncture on hemodynamics at peri-intratracheal intubation period under general anesthesia.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSION</b>Electroacupuncture at Neiguan (PC 6) and other points can stabilize changes of hemodynamics at the intratracheal intubation and increase safety of operation under anesthesia.</p>
