Key result
Postoperative hypoxia significantly prolonged intensive care unit length of stay compared to no hypoxia (4.1 vs 3.2 days), while body mass index demonstrated a U-shaped relationship with ICU stay.
Why the study?
Does body mass index affect postoperative hypoxia and intensive care unit length of stay in adult patients undergoing cardiac surgery with cardiopulmonary bypass?

Absolute Event Rate: 4.1% vs 3.2%
p-value: p=0.001
Obesity increases the risk of postoperative hypoxia after cardiac surgery, but ICU length of stay follows a U-shaped curve with prolonged stays observed in both underweight and moderate-to-morbidly obese patients.

Postoperative hypoxia was associated with longer ICU stay after cardiac surgery; hypothesis-generating for BMI's U-shaped effect on outcomes.
Ranucci et al. (2014) conducted a cohort in Cardiac surgery with cardiopulmonary bypass (n=5,023). Postoperative hypoxia vs. No postoperative hypoxia was evaluated on Intensive care unit length of stay (days) (p=0.001). Postoperative hypoxia significantly prolonged intensive care unit length of stay compared to no hypoxia (4.1 vs 3.2 days), while body mass index demonstrated a U-shaped relationship with ICU stay.
