Abstract

Background: The aim of this study is to compare heparin doseregimen calculated based on the lean body weight with traditionalheparin regimen in terms of ensuring adequate anticoagulation andcomplications associated with perioperative bleeding.Methods: This prospective, single-blind, randomized studyincluded a total of 100 adult patients (42 males, 58 females; meanage 52.7 years; range, 22 to 84 years) undergoing elective valvesurgery with cardiopulmonary bypass between June 2016 andJanuary 2017. Prior to cardiopulmonary bypass, heparin dose wasadjusted as 4 mg/kg, according to the actual body weight (n=50)and lean body weight (n=50). The minimal activated clotting timetarget value was accepted as 480 sec for cardiopulmonary bypassinitiation. Demographic and hemodynamic data, post-heparinactivated clotting time, additional heparin and perioperativetransfusion, postoperative drainage volumes, reoperations, andmortality were recorded.Results: Demographic data, cross-clamp and cardiopulmonarybypass times, and intraoperative transfusion requirement were notsignificantly different between the groups. The initial and total dosesof heparin, as well as the total dose of protamine, were significantlyhigher in the actual body weight group. Postoperative transfusionrates were also higher in this group. None of the patients in the leanbody weight group required reoperation, while three patients in theactual body weight group underwent reoperation.Conclusion: Our study results showed that adequate anticoagulationwas achieved with the titration of heparin dose calculated accordingto the lean body weight during cardiopulmonary bypass and reducedtotal heparin and protamine doses decreased postoperative bleedingand blood product transfusion requirement.

Özet

Amaç: Bu çalışmada geleneksel heparin rejimi ile yağsız vücut ağırlığına göre hesaplanan heparin doz rejimi yeterli antikoagülasyonun sağlanması ve perioperatif kanama ile ilişkili komplikasyonlar açısından karşılaştırıldı. Çalışma planı: Bu prospektif, tek kör, randomize çalışmaya Haziran 2016 - Ocak 2017 tarihleri arasında kardiyopulmoner baypas ile elektif kapak ameliyatı yapılan toplam 100 erişkin hasta (42 erkek, 58 kadın; ort. yaş 52.7 yıl; dağılım, 22-84 yıl) alındı. Kardiyopulmoner baypas öncesinde heparin dozu, aktüel vücut ağırlığına göre (n=50) ve yağsız vücut ağırlığına göre (n=50) olmak üzere 4 mg/kg olarak ayarlandı. Kardiyopulmoner baypasa başlanması için minimum aktive pıhtılaşma zamanı hedef değeri 480 sn. olarak kabul edildi. Demografik ve hemodinamik veriler, heparin sonrası aktive pıhtılaşma zamanı, ek heparin ve perioperatif transfüzyon, ameliyat sonrası drenaj miktarları, yeniden ameliyatlar ve mortalite kaydedildi. Bulgular: Demografik veriler, kros klemp ve kardiyopulmoner baypas süreleri ve ameliyat sırası transfüzyon ihtiyacı gruplar arasında anlamlı düzeyde farklı değildi. Heparinin başlangıç ve toplam dozlarının yanı sıra toplam protamin dozu, aktüel vücut ağırlığı grubunda anlamlı düzeyde daha yüksekti. Ameliyat sonrası transfüzyon oranları da, bu grupta daha yüksekti. Yağsız vücut ağırlığı grubunda hiçbir hastada yeniden ameliyat gerekli olmaz iken, aktüel vücut ağırlığı grubunda üç hasta yeniden ameliyat edildi. Sonuç: Çalışma sonuçlarımız kardiyopulmoner baypas sırasında yağsız vücut ağırlığına göre hesaplanan heparin doz titrasyonu ile yeterli antikoagülasyon sağlanabileceğini ve toplam heparin ve protamin dozlarının düşürülmesi ile ameliyat sonrası kanama ve kan ürünü transfüzyonu gereksinimin azaltılabileceğini göstermiştir
