Official Title: Effect of Transcutaneous Electrical Acupoint Stimulation(TEAS) on the Incidence of Hypotension After Spinal Anesthesia in Patients Undergoing Cesarean Section: a Prospecti

Brief Summary: The purpose of this study is to compare the effect of TEAS on hypotension after spinal anesthesia in patients undergoing cesarean section

Detailed Summary: Patients were randomly assigned to 3 groups, receiving TEAS , non-acupoint stimulation or no-stimulation after spinal anesthesia respectively. 1.4 ml of bupivacaine mixed with 0.2ml of 50% glucose was given for spinal anesthesia under lateral position. Then the patient was switched to supine position and the OR table was tilted to the left for 15 degree. The sensory loss level was assessed. The blood pressure and heart rate every 2min were recorded for 30min after spinal anesthesia. The adverse events and use of ephedrine adverse events were recorded as well.

Current Primary Outcome: Incidence of hypotension [ Time Frame: During 30min after spinal anesthesia ]

Original Primary Outcome: Same as current

Current Secondary Outcome:

  • Average systemic blood pressure(SBP) and diastolic blood pressure(DBP) [ Time Frame: During 30min after spinal anesthesia ]
  • Lowest SBP and DBP [ Time Frame: During 30min after spinal anesthesia ]
  • Dosage of ephedrine [ Time Frame: During 30min after spinal anesthesia ]
  • postoperative nausea and vomiting(PONV) score [ Time Frame: During 30min after spinal anesthesia ]
  • Incidence of dizzy and dyspnea [ Time Frame: During 30min after spinal anesthesia ]
  • Change of concentration of serum adrenaline and noradrenaline [ Time Frame: Immediately after TEAS ]


Original Secondary Outcome: Same as current
