NCT05716399

Brief Summary

This study is intended to include elderly patients who are selected to undergo lower limb and pelvic orthopedic surgery under spinal anesthesia. Through prospective, randomized and controlled clinical trials, the investigators will observe the effect of this treatment on the incidence of hypotension in elderly patients after spinal anesthesia through TEAS points Neiguan and Quchi before or during surgery, and further explore its related mechanisms.

Conditions

Outcome Measures

Primary Outcomes (1)

  • Incidence of hypotension

    30 mins after anesthesia, hypotension was defined as MAP\<25% of the baseline value

    30 mins after anesthesia

Study Arms (3)

Transcutaneous electric stimulation pretreatment group

EXPERIMENTAL

30 minutes before the implementation of spinal anesthesia, TEAS (density wave 10/50Hz, one side of Neiguan and Quchi points connected to two electrodes on the same wire on the electroacupuncture instrument) was continuously performed on both sides of Neiguan and Quchi points.

Device: Transcutaneous electric stimulation pretreatment

Transcutaneous acupoint electrical stimulation treatment group

ACTIVE COMPARATOR

Within 30 minutes after the occurrence of hypotension, TEAS (density wave 10/50Hz, one side of Neiguan point and Quchi point connected to two electrodes on the same wire on the electroacupuncture instrument) was continuously performed on both sides of Neiguan and Quchi points.

Device: Transcutaneous acupoint electrical stimulation treatment

Transcutaneous acupoint pseudo electric stimulation group

SHAM COMPARATOR

Paste the electrode, turn on the power, but no current output.

Device: Transcutaneous acupoint pseudo electric stimulation

Interventions

Within 30 minutes before spinal anesthesia or 30 minutes after hypotension, TEAS (density wave 10/50Hz, one side of Neiguan and Quchi points connected to two electrodes on the same wire on the electroacupuncture instrument) was continuously performed on both sides of Neiguan and Quchi points, and the current intensity was only as high as the patient could comfortably tolerate (the electrical stimulation intensity was 2-3 times of the sensory threshold, for example, if the electrical stimulation intensity was 5 mA, 10-15 mA was used for stimulation), Record the specific value of current. FTEAS group pastes electrode piece, turns on the power, but there is no current output.
