NCT05724095

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • incidence of hypotension by 30 minutes after spinal anesthesia

    Hypotension episodes, defined as reductions in systolic blood pressure exceeding 30% of baseline or \<90 mm Hg

    from injection of anesthetics to 30 minutes after injection, in a total of 30 minutes

Secondary Outcomes (8)

  • lowest systolic blood pressure during 30 minutes after spinal anesthesia

    from injection of anesthetics to 30 minutes after injection, in a total of 30 minutes

  • dose of ephedrine

    from injection of anesthetics to 30 minutes after injection, in a total of 30 minutes

  • nausea and vomiting score

    from injection of anesthetics to 30 minutes after injection, in a total of 30 minutes

  • incidence of dizzy

    from injection of anesthetics to 30 minutes after injection, in a total of 30 minutes

  • incidence of apnea

    from injection of anesthetics to 30 minutes after injection, in a total of 30 minutes

  • +3 more secondary outcomes
