[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.


CONCLUSIONS
Electroacupuncture at Neiguan (PC 6) and other points can stabilize changes of hemodynamics at the intratracheal intubation and increase safety of operation under anesthesia.
