Açık Kalp Cerrahisinde Diyabetik Hastalarda Preoperatif Albümin Değerinin Renal Fonksiyon Üzerine Etkisi.

Objective: In cardiac surgery, low serum albumin level is an important risk factor that increases mortality and morbidity in the postoperative period. Diabetes mellitus may affect this clinical condition by causing albumin loss with proetinuria. In this study, the effects of preoperative albumin values and the presence of diabetes mellitus (DM) on postoperative renal failure were investigated. Method: Patients who underwent coronary artery bypass grafting between 01.01.2015-31.12.2019 in our clinic were retrospectively analyzed. Patients who received dialysis treatment in the preoperative period, whose ejection fraction was below 50%, and who underwent emergency surgery were excluded from the study. The patients were divided into 3 groups according to the serum albumin levels before surgery. Patients with serum albumin level ≥3.5 mgr/dL Group 1; those between 2.5-3.5 mg/dL Group 2; patients with ≤ 2.5 were named as Group 3. Later, these 3 groups were divided into 2 subgroups according to the presence of DM. Results: 308 patients who underwent coronary artery bypass surgery were included in the study. The demographic characteristics, peroperative data and operative data of the patients were similar. The need for renal replacement therapy was higher in Group 2 and Group 3 than in Group 1 in the postoperative period. Conclusion: Preoperative low serum albumin is a risk factor for the development of acute renal failure in the postoperative period, and the presence of DM adversely affects this condition. Close follow-up of these patients positively contributes to reducing mortality and morbidity. [ABSTRACT FROM AUTHOR]
