ABSTRACT
Objective To evaluate the efficacy of puerarin for prevention of brain injury in the patients undergoing open heart surgery under cardiopulmonary bypass (CPB).Methods Thirty ASA physical status Ⅲ patients of both sexes,aged 50-64 yr,weighing 50-75 kg,scheduled for elective cardiac valve replacement under general anesthesia,were randomly divided into 2 groups (n =15 each) using a random number tablecontrol group(group C) and puerarin group (group P).Puerarin 400 mg was infused intravenously over 30 min immediately at skin incision in group P and the equal volume of 5% glucose-sodium chloride injection was given in group C.Before induction of anesthesia (T0),at 30 min of CPB (T1),immediately after aortic unclamping (T2),and at 6,12 and 24 h after termination of CPB (T3.5),blood samples were collected from the jugular venous bulb for determination of the plasma concentration of neuron-specific enolase (NSE) and S-100 β protein.P300 eventrelated potential latency and amplitude were determined and cognitive function was assessed by Mini-Mental State Examination (MMSE) score at 1 day before surgery and 7 days after surgery.The patients were diagnosed as having post-operative cognitive dysfunction when MMSE score before surgery-MMSE score after surgery ≥ 2,or when M MSE score≤ 24.Results Compared with group C,the concentrations of plasma NSE and S-100 β protein were significantly decreased at T15,and P300 event-related potential latency was shortened,P300 event-related potential amplitude was increased,and the incidence of postoperative cognitive dysfunction was decreased at 7 days after operation in group P.Conclusion Puerarin can prevent the brain injury in the patients undergoing open heart surgery under CPB.
