AIM To observe the effects of Lanwei acupiont blockade with drug to prevent pull re,ponse duringappendectomy.METHODS Sixty patients with appendix (37 male and 23 female, ASA Ⅰ - Ⅱ) aged from 16 to 58 yearsold, were divided into two groups at random, and they underwent persistent epidural nerve ,lock and McBurney opening. Group A for experiment (nA = 30) received persistent epidural nerve blck plus druginjection of Lanwei acupoint. And the control group, group B (nB=30), received simple epidural nerveblock. No remarkable difference was found in the general data of both groups (P>0.05).RESULTS None of the experimental group had marked nausea and vomiting. Twenty-six cases belonged tograde 0 (account for 86.67%). Three cases were of grade Ⅰ. One case was of grade Ⅱ. None belonged tograde Ⅲ. There were fewer changes in HR, BP and SPO2 during the operation. Compared with the experimental group. The results in the control group showed obvious changes in HR,BP and SPO2, especially at the time of 5 minute post-pull appendix (P<0.01). Eleven cases belonged tograde Ⅲ (36.67%), seven cases to grade Ⅱ and Four cases to grade Ⅰ, only 2 cases to grade 0.CONCLUSION Adjusting the function of Zang and Fu, maintaining the coordination and the balanceamong Zang and Fu, drug injection of Lanwei acupoint may prevent vagus-vagus reflex. The method issimple, easy, inexpensive and effective. It is advantageous to anesthetic care during the operation.
