Pre-operative autologous blood donations. A five-year experience in Trinidad and Tobago

A pre-operative autologous blood donation programme was started in 1988 and made available to all doctors offering elective surgical procedures. Two hundred and seventy-seven (277) patients presented for autologous donation over a five-year period. Nine point four per cent were rejected because of low haemoglobin ( < 10.5 g/dl). The single biggest user of the programme was the Princess Elizabeth Hospital for handicapped persons. Patients undergoing orthopaedic procedures gave 50% of the donations, and ranged in age from 10 to 73 years. The oldest donor was a 73-year-old man who had an abdominal aortic aneurysm replaced. Gynaecological surgeons in the public and private sectors together provided 43.9% of donors, 3.6% of these underwent elective Caesarean Section, each donating one unit of blood at 36 weeks. Patients undergoing general surgical procedures comprised 10.4% of donors. Autologous donors contributed 1.3% of the total number of donations over this period.
