Retrospective cohort study analyzes the link between blood pressure and lactate clearance post-cardiac surgery, suggesting blood pressure may not significantly affect outcomes.
Key Points
Lactate clearance occurs largely independently of postoperative blood pressures in the first 16 hours.
Average cleared lactate fraction at 16 hours post-surgery was 85.9%, indicating effective clearance.
Lower early systolic blood pressures showed a slight trend toward delayed lactate clearance, with p=0.14.
Inotropic support on postoperative day 1 was statistically significant for lactate clearance, p=0.03.
