Title: Cardioprotection of electroacupuncture in patients undergoing heart surgery with cardiopulmonary bypass
Abstract: Objective
To evaluate the cardioprotection of electroacupuncture (EA) in the patients undergoing heart surgery with cardiopulmonary bypass(CPB).
Methods
Forty American Society of Anesthesiologists physical status Ⅲ patients, aged 18-55 yr, of New York Heart Association Ⅱ- Ⅲ, scheduled for elective cardiac valve replacement with CPB, were divided into 2 groups(n=20 each)using a random number table: control group (group C) and group EA.In group EA, bilateral Neiguan, Ximen, Shenmen and Baihui acupoints were stimulated with an electric stimulator with the frequency of 2 Hz from 20 min before anesthesia induction until the end of operation, and the optimal intensity was selected according to the patient′s tolerance when awake.Before EA and at 30 min of CPB, 30 min, 1 h and 2 h after termination of CPB and 6 and 24 h after operation, blood samples were taken from the central vein for determination of concentrations of heart-type fatty acid binding protein and cardiac troponin I in plasma (by enzyme-linked immunosorbent assay) and concentrations of malondialdehyde (using hydroxylamine method). Cardiac contractility was scored at 1, 6 and 24 h after operation, and arrhythmia was scored at 24 h after operation.
Results
Compared with group C, the plasma concentrations of malondialdehyde at 30 min and 1 and 2 h after termination of CPB and 6 h after operation, plasma concentrations of cardiac troponin I at 24 h after operation, and plasma concentrations of heart-type fatty acid binding protein at 30 min of CPB and 24 h after operation were significantly decreased, and the arrhythmia score and cardiac contractility score at 6 and 24 h after operation were decreased in group EA (P<0.05).
Conclusion
EA can inhibit lipid peroxidation and exerts cardioprotection in the patients undergoing heart surgery with CPB.
