Blood utilisation in open heart surgery at Green Lane Hospital
Insights
This study surveyed blood use in open heart surgery patients. Regular autologous transfusion significantly reduced homologous blood needs, with many patients receiving none.
Area of Science:
- Cardiovascular Surgery
- Transfusion Medicine
Background:
- Open heart surgery, particularly for coronary artery disease, has historically high blood transfusion requirements.
- Optimizing blood management is crucial for patient outcomes and resource allocation.
Purpose of the Study:
- To analyze blood utilization patterns in patients undergoing open heart surgery.
- To identify factors influencing homologous blood and blood product consumption.
Main Methods:
- A retrospective survey of blood usage in 166 open heart surgery patients over three months in 1980.
- Analysis of homologous blood units and blood products per patient.
- Evaluation of autologous blood transfusion practices.
Main Results:
- Average homologous blood use was 2.55 units per patient, with a total demand of 3.55 donors/patient including blood products.
- Coronary artery disease accounted for over two-thirds of the operations.
- 23% of bypass procedures and 13% of patients received no homologous blood or products.
Conclusions:
- Regular autologous transfusion of oxygenator blood post-bypass was effective in reducing overall blood usage.
- Significant reductions in homologous blood and blood product transfusion are achievable in open heart surgery.
Abstract:
Blood utilization in 166 patients who underwent open heart surgery over a period of three months in 1980 at Green Lane Hospital has been surveyed. Over two-thirds of the operations were for coronary artery disease. For each hospitalized patient an average of 2.55 units of homologous blood were used. Including blood products, the total demand on the blood transfusion service was 3.55 donors/patient. Regular autologous transfusion of oxygenator blood post-bypass was a major factor in reducing blood usage. No blood was used in 23% of the bypass procedures and 13% of patients did not receive any homologous blood or blood products.
