Blood conservation for myocardial revascularization. Is it cost effective?

Area of Science:

• Cardiovascular Surgery
• Transfusion Medicine
• Health Economics

Background:

• Myocardial revascularization often necessitates blood transfusions, increasing risks and costs.
• Blood conservation strategies aim to minimize allogeneic blood exposure and its associated complications.

Purpose of the Study:

• To evaluate the efficacy of intraoperative autotransfusion and postoperative reinfusion in reducing transfusion requirements.
• To determine the cost-effectiveness of these blood conservation techniques in cardiac surgery patients.

Main Methods:

• Prospective study of 284 patients undergoing myocardial revascularization.
• Phase 1: Intraoperative Cell Saver System vs. control. Phase 2: Cell Saver System plus autotransfusion system vs. control.
• Analysis of packed red cell units transfused and total blood-related costs.

Main Results:

• Both phases showed significant reductions in bank blood use compared to control groups.
• Phase 1: 2.8 units (Cell Saver) vs. 4.7 units (control). Phase 2: 1 unit (both systems) vs. 3 units (control).
• Blood conservation techniques were cost-effective, with costs of equipment offset by savings in blood products.

Conclusions:

• Intraoperative autotransfusion alone and combined with postoperative reinfusion substantially decrease bank blood requirements.
• Implementing these blood conservation methods is economically beneficial in myocardial revascularization procedures.
