Predictors of post XXXX and blood transfusion in cardiac surgery.

INTRODUCTION: In spite of the recent advances in heart surgery, @entity1 undergoing cardiac surgery with cardiopulmonary bypass are at risk of developing significant @entity548 and substantial blood requirements. OBJECTIVE: To evaluate the impact of some perioperative predictors of @entity548 , and blood transfusion after heart surgery and offer suggestions on preventive measures. DESIGN AND METHODS: A prospective analytical study. The perioperative factors studied were haemoglobin level, international normalised ratio (INR), platelet count, and total bypass time. Eighty-seven consecutive @entity1 who underwent heart surgery in the year 2004 were selected. Each @entity1 had laboratory work up which included full blood count, clotting profile, kidney and liver function tests. The total @entity190 within the first twenty-four hours and the total units of blood transfused before the @entity1 was discharged were also recorded. RESULTS: Pre-operative haemoglobin was significant in determining the total units of blood received by a @entity1 . Increasing total bypass time caused a significant increase in the percentage reduction of the pre-operative platelet count (p <0.004). However even though there was an increasing trend of @entity548 with increase in total bypass time, this was not significant from the analysis (p<0.069). The percentage reduction in platelet count and immediate postoperative platelet count were significant predictors of @entity86 (p <0 .009) and (p <0.003) respectively. CONCLUSION: Pre-operative haemoglobin, percentage @entity1423 after cardiopulmonary bypass and immediate postoperative platelet count are significant predictors of @entity86 and blood requirements.
