体外循环术后急性肾功能衰竭的高危因素分析

Analysis of Risk Factors for Acute Renal Failure After Open Heart Surgery

工目的：探讨急性肾功能衰竭的高危因素及防治方法。方法：对21例体外循环心脏术后急性肾功能衰竭患者及对照组进行研究。结果：高龄，术前心、肾功能情况及体外循环时间的长短等均为易发因素。经过治疗，肾功能均有所改善，其中6例腹膜透析，1例血液透析。15例康复出院，6例死亡，死亡率28.6％。结论：分析表明，降低急性肾衰的发生率及死亡率主要在于对术前高危因素的重视及术中术后积极的防治措施。

objective: To study the risk factors acute renal failure after open heart surgery with methods of the prevention and treatment. Methods: 21 patlents with acute renal failure after open heart surgery under cardiopulmonary bypass (CPB) were compared with controls. Results: Many risk factors can cause acute renal failure after open heart surgery including age, heart and renal functions be fore operation and CPB time. The renal function was greatly improved after proper treatment (6 patients with peritoneal dialysis, 1 patient with hemodialysis). 15 patients were discharged uneventfulIy from hospital except 6deaths with a hospital mortality rate of 28. 6 %. Conclusions: To reduce the morbidity and mortality rate of acute renal failure after open heart surgery, great attention needs to be paid bOth to the risk factors preoperatively and to proper treatment.
