Objective:
To follow the haematological response in elderly patients to preoperative autologous blood collection.
Design:
A prospective, randomised study.
Setting:
Malmö General Hospital, Sweden.
Patients:
Sixty patients with a mean age of 71 years (range, 60-82 years) who were to undergo total hip replacement were randomly divided into four groups of 15. One group served as control. Three units of blood were collected from patients in the other three groups, the first unit at least 30 days before the planned operation, with an average interval of 10 days between collections. Iron supplementation was given to one group as a substitution remedy, another group was given iron and folic acid and the third group was without supplementation during the collection period.
Main Outcome Measures:
Haematological and biochemical tests were performed on blood samples taken at the time of each collection, on the morning of the hip replacement operation, and ten days after and six weeks after the operation.
Results:
No major complication was encountered with blood collection. The patients tolerated the procedure very well including the substitution remedies. Haematological and biochemical parameters remained within the normal range during the collection period and after the operation. No patient in the autologous groups needed homologous blood during the operation; three units of homologous blood were used after the operation in these patients.
Conclusion:
Preoperative blood collection from the elderly is safe and well tolerated. The procedure should be encouraged in elective orthopaedic operations regardless of age.
