[Effect of transcutaneous acupoint electrical stimulation on blood bioactive compounds involving cerebral injury during craniotomy].

Objective: To observe the effect of transcutaneous acupoint electrical stimulation (TAES) on plasma ET, CGRP and serum IL-6, S100beta during craniotomy.

Methods: Fifty patients scheduled for neurosurgery were randomly divided into TAES group (n=25) and control group (n=25). TAES (2/100 Hz, 8-12 mA) of bilateral Hegu (LI 4)-Quchi (LI 11), Zusanli (ST 36)-Sanyinjiao (SP 6) was administrated for patients of TAES group starting 30 min before anesthesia till the end of the operation.
