Management of Renal Insufficiency in Patients Undergoing Cardiac Surgery

Aim:To review the experience of perioperative management of renal insufficiency in patients undergoing open heart surgery.Clinical material and method:Fortythree patients with renal insufficiency underwent open heart surgery from 1990 to 1994.There were 30 men and 13 women with a mean age of 45 years.Preoperative heart function(NYHA) was class II in 7 patients,class III in 18 and class IV in 18.According to creatine and BUN level,renal failure was classified as mild in 34 cases,moderate in 5 and severe in 4.Surgical procedures performed included correction of congenital heart diseases in 5,valve replacement in 36 and coronary artery bypass grafting in 2.Before operation,2 patients received hemodialysis for severe renal failure.After surgery,14 patients received peritoneal dialysis and 5 had hemodialysis.Results:The operative mortality was 18.6%(8/43).The main causes of deaths were multiple organ failure(87.5%) and arrhythmia(12.5%).The morbidity rate was 53.5%.Normal renal function was found in 18 patients postoperatively.4 cases had mild renal insufficiency,7 moderate and 14 severe.The incidence of complications in those patients was 27.8%,50%,85.7% and 71.4%,respectively.Conclusion:Operative mortality and morbidity are closely related to the degree of postoperative renal insufficiency.Proper management during perioperative period would improve surgical outcome.
