Frequency of Electrical Acupoint Stimulation on Hypotension in TAVR Patients

The Influence of Electrical Acupoint Stimulation at Different Frequencies on Hemodynamics During Anesthesia Induction in Patients Undergoing TAVR Surgery

Within 30 minutes before anesthesia, acupoint electrical stimulation at different frequencies were applied at Neiguan, Jian Shi, and Baihui. The changes in blood pressure during the anesthesia induction period were compared between the high-frequency group and the low-frequency group.

Inclusion Criteria:

• The age of the patients is 60 years or older;
• Patients who are scheduled to undergo TAVR surgery under general anesthesia;

Exclusion Criteria:

• Body mass index less than 18 kg/m2 or greater than 30 kg/m2;
• Hemodynamic instability (severe arrhythmia, decompensated heart failure);
• Hypotension after admission requiring intervention with vasoactive drugs;
• Severe liver or kidney dysfunction;
• Those who are contraindicated for electrical stimulation, including those with local skin damage, infection, or having implanted electrophysiological devices in the body.
