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

Secondary Outcome Measures:
  • 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 ]

Enrollment: 150
Study Start Date: September 2013
Study Completion Date: August 2014
Primary Completion Date: August 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: TEAS Treatment
Patients were given 30min of TEAS at PC6 after spinal anesthesia
Other: TEAS
Electric stimulation was given through electrode attached to specific acupoints
Other Name: Transcutaneous electrical acupoint stimulation
Sham Comparator: Non-acupoint stimulation
Patients were given 30min of electrical stimulation at shoulder after spinal anesthesia
Other: Non-acupoint stimulation
Electric stimulation was given through electrode attached to the shoulder
No Intervention: Control
No stimulation was given

Detailed Description:
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.
