Introduction: Coronary artery bypass graft (CABG) patients are subjected to controlled hypoperfusion during surgery, particularly during cardiopulmonary bypass. In search of parameters to monitor the effects on tissue perfusion and circulation and predict outcomes of these patients, the researcher aimed to determine the relationship of AVC02 gap with post-operative complications post-CABG.

Methods: This is a cohort study of seventy (70) CABG patients. They were grouped according to the arterial venous C02 (AVC02) gap: 5mmHg, and analyzed as to their postoperative outcomes. The homogeneity of patient characteristics between groups was tested using independent T-Test. The association between AVC02 gap and outcomes were determined and tested using logistic regression analysis.

Results: Baseline characteristics of subjects were comparable. Thirty-two patients (45.7%) were observed to have post-operative complications. 71.9% (23/32) were noted to have AVC02 gap of >5mmHg with odds ratio of 1.49 (P = 0.44). However, the length of ICD stay and hospital stay had no association (P = 0.13 and P= 0.10 respectively)

Conclusion: There is no relationship between arterial-venous C02 gap and postoperative complications of patients who underwent coronary artery bypass grafting.
