Background / introduction
Cardiopulmonary bypass (CPB) flow rate required for optimal perfusion during cardiac surgery is calculated using body surface area (BSA). However, obese patients with higher BSA may require an altered flow rate. In obese patients BSA reflects partly body fat that is hypothesized to require less perfusion than internal (organ)tissue. Current CPB flow rate calculations are inconsiderate of excessive body fat. It is likely that this leads to excessive CPB flow rate. It is yet unknown how obese patients are affected by current CPB flow calculations. Albeit that the current obesity epidemic demands to investigate the optimal cardiopulmonary bypass flow rate in obese patients.
Research question / problem definition
We aim to investigate cardiopulmonary bypass flow and postoperative morbidity and mortality in obese patients undergoing cardiac surgery.
