Abstract:
Objective:To evaluate the efficacy of left heart attracting pressure monitoring technology applied in cardiopulmonary bypass (CPB) in cardiac surgery.Methods:Eighty patients of both sexes, aged 40-64 yr, weighing 50-80 kg, of American Society of Anesthesiologists physical status Ⅱ-Ⅳ, with New York Heart Association grade Ⅱ or Ⅲ, with left ventricular ejection fraction≥40%, undergoing elective cardiac valve replacement, were divided into 2 groups using a random number table method: traditional left heart aspiration group (T group) and modified left heart aspiration group (M group), with 40 patients in each group.The rotation speed of left ventricular suction pump was adjusted according to left ventricular suction volume and surgical field clarity in group T and by monitoring the pressure in the left suction tube in real time in group M. After aspiration returned to normal aspiration, blood of the left heart returned after aspiration was collected to determine the concentration of free hemoglobin.The number of adjustments after left ventricular aspiration, intraoperative hemoglobinuria, and occurrence of tissue sediment in the aspiration tube after operation were recorded.Results:Compared with T group, the concentration of free hemoglobin, incidence of intraoperative hemoglobinuria and incidence of tissue sediment in the aspiration tube after operation were significantly decreased, and the number of adjustments after left ventricular aspiration was decreased in M group ( P<0.05). Conclusion:Left heart attracting pressure monitoring technology can be safely and effectively applied in CPB in cardiac surgery.
