Abstract

Aim: Postoperative bleeding is one of the most frequently encountered complications following coronary artery bypass grafting (CABG). This study aims to investigate preoperative and intraoperative risk factors affecting postoperative bleeding in CABG surgery. Methods: A total of 242 patients who underwent CABG between March 2019 and January 2023 were retrospectively analyzed. Based on postoperative bleeding volume, patients were classified into two groups: normal bleeding (Group N) and excessive bleeding (Group B). The groups were compared in terms of demographic, clinical, and perioperative variables. Results: Patients in Group B demonstrated significantly lower preoperative platelet counts (p=0.005), a lower prevalence of COPD (p=0.01), and longer anesthesia durations (p=0.033). Logistic regression analysis identified the absence of COPD (OR: 0.202; 95% CI: 0.054–0.759) and low platelet levels (OR: 0.995; 95% CI: 0.991–0.999) as independent predictors of excessive bleeding after CABG surgery. Conclusion: The findings indicate that reduced preoperative platelet count and the absence of COPD are significant risk factors for excessive bleeding following CABG. Moreover, these patients exhibited higher rates of postoperative complications and mortality.

Özet

Amaç: Koroner arter bypass greftleme (CABG) cerrahisi sonrasında karşılaşılan en önemli komplikasyonlardan biri postoperatif kanamadır. Bu çalışmanın amacı, CABG cerrahisi geçiren hastalarda postoperatif kanamayı etkileyen preoperatif ve intraoperatif risk faktörlerini araştırmaktır. Yöntem: Bu çalışmada Mart 2019 ile Ocak 2023 tarihleri arasında CABG cerrahisi uygulanan 242 hasta retrospektif olarak değerlendirildi. Postoperatif dönemde kanama miktarına göre hastalar normal kanama (Grup N) ve aşırı kanama olanlar (Grup B) şeklinde iki gruba ayrıldı. Gruplar demografik, klinik ve perioperatif değişkenler açısından karşılaştırıldı. Bulgular: Grup B'deki hastalarda anlamlı bir şekilde daha düşük preoperatif trombosit sayısı (p=0,005), daha düşük KOAH prevalansı (p=0,01) ve daha uzun anestezi süreleri (p=0,033) olduğu saptandı. Lojistik regresyon analizi, KOAH öyküsü olmayışını (OR: 0,202; %95 GA: 0,054–0,759) ve düşük trombosit seviyelerini (OR: 0,995; %95 GA: 0,991–0,999) KABG ameliyatından sonra aşırı kanama için bağımsız risk faktörleri olarak tanımladı. Sonuç: Bu sonuçlar, düşük preoperatif trombosit düzeyi ve KOAH öyküsünün olmamasının, CABG cerrahisi sonrası aşırı kanama için bağımsız risk faktörleri olduğunu ortaya koymuştur. Ayrıca, aşırı kanaması olan hastalarda postoperatif komplikasyonların ve mortalitenin daha sık görüldüğü bulunmuştur.
