Effect of Different Frequencies of Electrical Acupoint Stimulation on Blood Pressure During Anesthesia for TAVR Surgery A Study on Hemodynamic Changes in Patients Aged 60 and Older

What this Trial Is About

Researchers are investigating how electrical stimulation at different frequencies on specific acupoints affects blood pressure changes during anesthesia induction in patients undergoing Transcatheter Aortic Valve Replacement TAVR surgery. The study compares the effects of high-frequency and low-frequency electrical acupoint stimulation to understand their influence on hemodynamic stability. Participants receive electrical stimulation at the Neiguan, Jian Shi, and Baihui acupoints starting 15 minutes before anesthesia induction and continuing until 15 minutes after. Two groups receive different frequencies one group at 100Hz high-frequency and the other at 2Hz low-frequency. This randomized, quadruple-blind study carefully monitors the effects during the anesthesia induction period. During the study, researchers measure the change in mean arterial pressure from induction start to 15 minutes after and record the area under the curve for this change. They also track occurrences of hypotension, dosage of vasoactive drugs used, complications such as cardiovascular events or acute kidney injury, length of hospital stay, ICU admission rates, quality of recovery, and discharge assessment scores. Participants are followed from surgery through discharge and up to 30 days post-surgery to assess overall outcomes.
