title: [Effect of transcutaneous electrical acupoint stimulation on BIS and VAS in artificial abortion operation].
abstract: OBJECTIVE
  To observe the sedative and analgesic effects of transcutaneous electrical acupoint stimulation (TEAS) in patients with artificial abortion operation.
  
  
  METHODS
  Ninety patients, with American Society of Anesthesiologists (ASA) physical status I - II, and scheduled for artificial abortion operation, were randomly divided into three groups, 30 cases in each group. The patients in group A were treated with TEAS on Neiguan (PC 6) and Taichong (LR 3), in group B with paracervical block anesthesia (BA), and in group c with both TEAS and BA. Continuous monitoring of the mean arterial blood pressure (MAP), heart rate (HR), oxygen saturation and bispectral index (BIS) of the patients lasted to 30 min after the operation. The BIS, Visual Analogue Scale (VAS) during the operation and the adverse reactions after the operation were analyzed.
  
  
  RESULTS
  After 15 minutes TEAS, the BIS in group A and C were decreased significantly, with no significant difference between the two groups (P > 0.05) and being both better than that in group B (both P < 0.05), which had no significant change. There were no significant differences in the VAS among the three groups (all P > 0.05), while the adverse reactions in both group A and C were lower than that in group B (both P < 0.05).
  
  
  CONCLUSIONS
  TEAS has sedative and analgesic effect during artificial abortion operation and can decrease the adverse reactions.
