Postoperative Outcome of Coronary Artery Bypass Graft Surgery in Patients with and without Renal Dysfunction at Tertiary Care Hospital, Karachi

Abstract

Objectives: Renal dysfunction is a significant complication in patients undergoing coronary artery bypass graft (CABG) surgery. Understanding the frequency and risk factors associated with renal dysfunction in the context of CABG is crucial, as it has profound implications for patient outcomes, including increased morbidity, prolonged hospital stays, and higher mortality rates. Methodology: Quantitative and qualitative data was collected, presented and analyzed. Effect modifiers were controlled through stratification to see the effect of these on the outcome variable. Post stratification chi square test was applied taking p-value of ≤0.05 as significant. Results: A total of 135 patients who met the inclusion and exclusion criteria were included in this study. Mean age and duration of CABG in our study was 62.39±10.49 years and 3.72±2.24 hours. 68 (50.4%) and 67 (49.6%) were male and female. Out of 135 patients, 79 (58.5%) and 56 (41.5%) had and did not have renal dysfunctional. Patients who had renal dysfunction had higher mortality, prolonged ventilation and prolonged postoperative stay Conclusion: In conclusion, renal dysfunction remains a common and serious complication in patients undergoing coronary artery bypass graft (CABG) surgery. Its occurrence significantly impacts patient outcomes, contributing to increased morbidity, prolonged hospitalization, and elevated mortality rates. By implementing targeted interventions and monitoring protocols, healthcare providers can mitigate the risk of renal impairment, ultimately enhancing the overall success and safety of CABG procedures.
