Abstract

Aim: In our study, we aimed to comparatively examine the effect of HbA1c levels and diabetes disease on patients undergoing isolated coronary bypass surgery. Material and Methods: 200 consecutive patients (152 male, 48 female, mean age 61.1) who underwent coronary artery bypass surgery (CABG) in our hospital were included in the study. The patients were divided into two groups. Group 1 consisted of patients with HbA1c ≥6.5 % (n=100) and group 2 consisted of patients with HbA1c 7.65% was the threshold value for occurrence of mediastinitis with a sensitivity of 80% and specificity of 65.6%. Conclusion: As a result, poor control of blood glucose levels following CABG is a risk factor for infection and HbA1c is a significant marker for identification of preoperative infection risk.

Özet

Amaç: Çalışmamızda izole koroner bypass ameliyatı uygulanan hastalarda HbA1c düzeyi ve diyabet hastalığının etkisini karşılaştırmalı olarak incelemeyi amaçladık. Gereç ve Yöntemler: Çalışmaya hastanemizde koroner baypas cerrahisi geçiren ardışık 200 hasta (152 erkek, 48 kadın, yaş ortalaması 61,1) dahil edildi. Hastalar iki gruba ayrıldı. Grup 1, HbA1c seviyesi ≥ %6,5 olan hastalardan (n = 100) ve grup 2, HbA1c seviyesi %7.65 değerinin, %80 duyarlılık ve %65 özgüllük ile mediastinit için eşik değer olduğunu gösterdi. Sonuçlar: Sonuç olarak, koroner baypas cerrahisi sonrası kan şekeri düzeylerinin yetersiz kontrolü enfeksiyon için bir risk faktörüdür ve HbA1c preoperatif enfeksiyon riskinin belirlenmesinde önemli bir belirteçtir.
