Abstract:
Objective To explore the effect of transcutaneous electrical acupoint stimulation on limb ischemia - reperfusion injury (IRI) induced by tourniquet in the very elderly patients. Methods Forty patients of both sexes, aged> 75 year, with body mass index of 20~30 kg/m2, of American Society of Anesthesiologists physical status II or Ⅲ , undergoing knee arthroplasty under combined spinal-epidural anesthesia were randomly divided into 2 groups (n=20 each): TEAS group (group T) and control group (group C). After anesthesia, patients in group T received continuous TEAS at the bilateral points of Neiguan and Hegu until the tourniquet de.ates.
