【Abstract】 Objective To analyze the factors leading to renal function damage after cardiac surgery with cardiopulmonary bypass(CPB) and to discuss the approaches of prevention and treatment. Methods 31 patients with renal functional lesion after open heart surgery under cardiopulmonary bypass were divided into two groups basing on prognosis : I,dead 24 cases and Ⅱ,cured 7 cases. Results Renal dysfunction occurred after operation with different degree in the two groups, the duration and severity of low cardiac output in the dead group was significantly higher than that of the cured group (P<0.05). Conclusion Low cardiac output may be the most important factor leading to acute renal failure (ARF) and affecting the prognosis. To reduce the morbidity and mortality of ARF after CPB, great attention needs to be paid on controlling the risk factors and preventing the development of mild or moderate renal dysfunction. Dialysis should be performed in the early stage of ARF.更多还原
