Abstract

Objective: There are conflicting results about renoprotectiveeffects of remote ischemic preconditioning(RIPC) reported in previous studies. This study is designedto investigate the effects of this application on renalfunction by means of certain deliberate biomarkersduring the early postoperative period in patients undergoingcoronary artery bypass graft (CABG) surgery.Material and Methods: This prospective, randomized,and blinded study was performed in patients who underwentisolated CABG surgery together with cardiopulmonarybypass (CPB) after eliminating factors thatmay confound biomarkers that indicate renal ischemiareperfusioninjury. The authors randomly assignedpatients to RIPC to the left lower extremity using aninflated (study group) or deflated (control group). bloodpressure cuff. Renal functions were analyzed by measuringcystatin C, neutrophil gelatinase-associated lipocalin(NGAL) and creatinine levels at 3 different timepoints namely 1 hour (T1) after CPB and 6 hours (T2)after skin closure, and 24 hours postoperatively (T3).Results: There were no differences between the two groupsin terms of demographic values and the hemodynamicparameters. Plasma cystatin C and creatinin levelswere significantly higher in the control group than thoseof the study group at all time points. Plasma NGALlevels were higher in the control group than in the studygroup at two time points, p=0,001 for time; p=0,243 forgroup respectively.Conclusion: In low risk patients with on- pump CABGsurgery, RIPC seems to protect renal functions. Furtherstudies with different risk groups should also be plannedto determine whether this procedure is useful incardiac surgery patients.

Özet

Amaç: Uzak-iskemik ön koşullanmanın böbrek üzerine olan koruyucu etkileri hakkında birbiriyle çelişen pek çok çalışma bulunduğu için bu uygulamanın koroner arter baypas (CABG) cerrahisi geçiren hastalarda erken postoperatif dönemde böbrek koruyucu etkisi olup olmadığını belirli biyobelirteçler aracılığıyla araştırmak amacıyla bu çalışma planlandı. Gereç ve Yöntem: Prospektif, randomize, kör çalışma; kardiyopulmoner baypas kullanılarak koroner arter baypas cerrahisi yapılan hastalarda (iskemireperfüzyona bağlı böbrek hasarını gösteren biyobelirteçlerde karışıklığa neden olabilecek faktörler elimine edildikten sonra) yapıldı. Hastalar randomize olarak pressure-cuff şişirilerek uzak-iskemik ön koşullanma yapılan (çalışma grubu) ve yapılmayan (kontrol grubu) 2 gruba ayrılmıştır. Böbrek fonksiyonları için 2 farklı zamanda; (T1: kardiyopulmoner baypastan 1 saat sonra, T2: cilt kapandıktan 6 saat sonra ve T3: postoperatif 24. saatte); sistatin C, nötrofil gelatinaz ilişkili lipokalin (NGAL) ve kreatinin düzeyleri incelenmiştir. Bulgular: Her 2 grup arasında demografik veriler ile hemodinamik parametreler arasında istatistiksel olarak anlamlı bir fark bulunamadı. Plazma sistatin C ve kreatinin değerleri bütün örnekleme zamanlarında kontrol grubunda çalışma grubuna göre anlamlı olarak farklı bulundu. Plazma NGAL düzeyleri kontrol grubunda çalışma grubuna göre iki örneklemede p=0.001 zaman, p=0.243 grup değerleri bulundu. Sonuç: Düşük riskli hastalarda kardiyopulmoner baypaslı CABG cerrahisi öncesi uygulanan uzak-iskemik ön koşullanma yönteminin böbrek fonksiyonlarını koruduğu görülmektedir. Bu yöntemin kalp cerrahisi hastalarında yararını gösterebilmek için farklı risk gruplarındaki hastalar için ileri çalışmalar planlanmalıdır.
