Objectives: Chronic renal failure patients who undergo open heart surgery have high morbidity and mortality rates in the postoperative period because of volume loading and electrolyte imbalance. In this study, we performed perioperative hemodiafiltration in our patients with chronic renal failure during open heart surgery and aimed to present our clinical results.

Materials and Method: This is a retrospective study including 15 open heart surgery patients who were on the regular dialysis schedule before the operation. Mean age was 59. F/M = 3/12. Distributions of the operations were 13 CABG, 1 MVR and 1 AVR. Ultrafilter was tied on arterial line of pump and was used along with CPB. Mean withdrawed ultrafiltrate fluid was 3800 ml.

Results: Mean cross clamp time was 83 min. Postoperative mean drainage was 725 ml/day. Cardiac tamponade occured in 1 patient, 2 had süperficial wound infection and 1 patient had postop pnomonia. Mean extubation time was 12h. Intensive care staying time was 4 days. Hospital staying time was 12.0 days. Mean number of blood transfusion was 4U. Hemodialysis was achieved in 1 of the patients (6.66%) postoperative 1st day, in 4 of them (26.66%) postoperative 2nd day, in 7 of the patients (46.66%) postoperative 3rd day, in 2 patients (13.33%) postoperative 4th day. Mortality was seen on 2 patients (13.33%) who were performed CABG in the early post operative period and 1(6.66%) patient who was performed CABG dead on postoperative 10th day.

Conclusion: Surgery mortality rates, postoperative wound healing and systemic infection rates are acceptable belonging to administration of ultrafiltration during open heart surgery. Extubation time, intensive care staying time and hospitalization times are almost standart rates. ©2008, Firat University, Medical Faculty
