Key result
Prolonged cardiopulmonary bypass time of 90 minutes or more during CABG was associated with a higher incidence of acute renal injury compared to shorter bypass times (6.59% vs 1.10%, p=0.050).
Why the study?
To compare post-operative in-hospital outcomes of on-pump CABG in patients with shorter CPB duration versus patients with longer CPB duration.
Does short duration of cardiopulmonary bypass (<90 minutes) reduce post-operative complications compared to long duration (≥90 minutes) in patients undergoing on-pump CABG?
Population
182 patients undergoing on-pump CABG
Comparison
CPB duration < 90 minutes vs CPB duration >= 90 minutes
Design
Cross-sectional study

Longer CPB time was associated with higher acute kidney injury after CABG; leaves open whether minimizing duration improves renal outcomes.

Prolonged cardiopulmonary bypass time (≥90 minutes) during CABG is associated with an increased risk of postoperative acute renal injury.
Arif et al. (2022) conducted a cross-sectional in Coronary artery disease (n=182). Prolonged cardiopulmonary bypass (≥ 90 minutes) vs. Short cardiopulmonary bypass (< 90 minutes) was evaluated on Acute Renal Injury (p=0.050). Prolonged cardiopulmonary bypass time of 90 minutes or more during CABG was associated with a higher incidence of acute renal injury compared to shorter bypass times (6.59% vs 1.10%, p=0.050).
