A survey of blood conservation methods in clinical practice in some urban south-eastern government hospitals in Nigeria
Abstract
General Objective: To assess the practice of blood conservation. Specific Objectives: To determine the methods of blood conservation in use, to assess the lower limit for hemoglobin for elective procedures, to determine transfusion trigger point in practice, to find out limitations in practice and ways to improve clinical practice. Materials and Methods: This was conducted in February 2009. Self-administered questionnaires were distributed among the surgeons and anesthetists in practice at the University of Nigeria Teaching Hospital, Enugu State University Teaching Hospital, Ebonyi State University Teaching Hospital and National Orthopaedic Hospital, Enugu. The data gathered was analyzed using the SPSS software. Results : Of participants who agreed to fill the questionnaires, more than 50% were males. The most prevalent specialty was general surgery (24.2%), followed by orthopedics (22.6%), obstetrics and gynecology (20.7%), and anesthesia (17.7%). The lowest hemoglobin limit before the patient was allowed into the theatre for elective procedures was 10 g/dl while individual transfusion trigger points ranged from hemoglobin of 6 to 10 g/dl. Majority of the doctors would avoid homologous blood transfusion in order to avoid transfusion-related diseases and reaction. Regarding knowledge of blood conservation methods and means of avoiding homologous blood, the use of diathermy was highest (12.33%), followed by preoperative blood donation (11.87%), use of hematinics (10.96%), and tourniquet 10.5%. Also, in practice, diathermy was the most frequently used (18.69%), followed by preoperative blood donation (16.16%), use of tourniquet (15.15%), while the Ovadje cell saver was least with 0.01%. Suggestions from respondents on the ways of limiting transfusion-related problems included optimization of patients (24.5%), improvement of standard of living (17.7%), and personnel training (13.3%). Conclusion: There is an agreement with the global trend geared toward minimizing the use of homologous blood by doctors in these hospitals. However, our practice must continually be refined by continuing medical education in order to keep everyone informed of changes in practice. The Government must improve the quality of service by the provision of unavailable infrastructure.
