Albumin in the pump prime: its effect on postoperative weight gain

Area of Science:

• Cardiovascular Surgery
• Anesthesiology
• Nephrology

Background:

• Cardiopulmonary bypass (CPB) is a critical procedure in cardiac surgery.
• Fluid management during CPB can influence patient outcomes, including postoperative weight gain.
• Albumin is a plasma expander that may affect fluid shifts.

Purpose of the Study:

• To investigate the effect of adding albumin to the CPB prime on postoperative weight gain.
• To evaluate the impact of albumin administration on fluid balance and urine output.

Main Methods:

• A prospective study involving patients undergoing non-emergency myocardial revascularization.
• Patients were divided into two groups: one receiving 250 ml of 5% human albumin in the CPB prime, and a control group.
• Standardized surgical, anesthetic, and postoperative management protocols were applied to all patients.

Main Results:

• No statistically significant differences were observed between the albumin and control groups.
• Key variables including intraoperative and postoperative fluid intake, urine output, fluid balance, and postoperative weight gain showed no significant variation.
• The addition of 250 ml of 5% human albumin to the pump prime did not alter postoperative weight gain.

Conclusions:

• The administration of 250 ml of 5% human albumin in the CPB prime does not impact postoperative weight gain in patients undergoing myocardial revascularization.
• Further research is warranted to explore the effects of larger volumes of albumin or other plasma expanders in the CPB prime.
