Electrical Acupoint Stimulation Reduces Intrathecal Anesthesia Induced Hypotension

Zhihong LU90 enrolled

Overview

The parturients may suffer from hypotension after spinal anesthesia and the incidence could be as high as 70-80% when pharmacological prophylaxis is not used. Acupuncture was reported to treat hypotension both in human and animal studies. Possible mechanisms include modulating cardiovascular and sympathetic system. In this prospective, double-blinded, randomized clinical trial, we tend to investigate the effect of transcutaneous electric acupoint stimulation (TEAS) on hypotension in parturients undergoing cesarean section.
