The effect of renal dose dopamine use on renal tubular function in diabetic patients undergoing coronary artery bypass graft surgery

Amaç: Bu çalışmada koroner arter baypas greftleme (KABG) yapılan diyabet hastalarında renal doz dopamin infüzyonunun profilaktik kullanımının klinik sonuçları değerlendirildi.Çalışmaplanı:Bu prospektif randomize çalışmada elektif KABG yapılması planlanan 40 ardışık diyabet hastası iki eşit gruba randomize edildi: grup 1'e anestezi indüksiyonundan itibaren 48 saat süreyle renal dozda (2.5-4.0 mg/kg/dk.) dopamin infüzyonu verildi; grup 2 ise tedavi edilmemiş kontrollerden oluşuyordu. Kardiyopulmoner baypas için aortik ve sağ atriyal kanülasyonu ile standart sternotomi tekniği uygulandı.Bul gu lar: Günlük idrar çıkışı, sıvı dengesi, serum kreatinin, kan üre düzeyleri ve kreatinin klirensi üç ve beşinci günlerde ölçüldü. Kontrol grubunda ameliyat sonrası üçüncü ve beşinci günlerde kreatinin klirens düzeyleri sırasıyla 24.8±12.3 mL/dk ve 18.1±10.1 mL/dk azaldı. Dopamin grubunda ameliyat sonrası üçüncü ve beşinci günlerde kreatinin klirens düzeyleri sırasıyla, 7.7±10.8 mL/dk. (p=0.005) ve 10.7±11.7 mL/dk. (p=0.001) arttı. Kontrol grubuna kıyasla, grup 1'deki hastaların serum kreatinin düzeyinde üçüncü ve beşinci günlerde daha az artış görüldü (p

Koroner arter baypas greft cerrahisi yapılan diyabet hastalarında renal doz dopaminin renal tübüler fonksiyon üzerine etkisi

Background: This study aims to evaluate clinical results of the prophylactic use of renal dose dopamine infusion in diabetic patients undergoing coronary artery bypass grafting (CABG). Methods: In this prospective randomized study, 40 consecutive diabetic patients who were scheduled for elective CABG were randomized into two equal groups: group 1 received dopamine infusion at renal dose (2.5-4.0 mg/kg/min) starting from induction of anesthesia for 48 hours; group 2 consisted of untreated controls. Standard sternotomy technique using aortic and right atrial cannulation was performed for cardiopulmonary bypass. Results: Daily urine output, fluid balance, serum creatinine, blood urea levels and creatinine clearance were measured at three and five days. In the control group, third and fifth postoperative day, creatinine clearance levels decreased about 24.8±12.3 mL/min and 18.1±10.1 mL/min, respectively. In the dopamine group, creatinine clearance levels in the third and fifth postoperative days increased by 7.7±10.8 mL/min (p=0.005) and 10.7±11.7 mL/min (p=0.001), respectively. Group 1 patients demonstrated less increase in serum creatinine level at three and five days than the controls (p
