Background: Preoperative anemia in surgical patients scheduled for major procedures results in poor outcomes, hence the need for full optimization of packed cell volume (PCV) before surgery. This study aims to assess preoperative PCV and category of surgery as predictors of intraoperative blood transfusion in a tertiary healthcare facility in Zaria, Nigeria.
Patients and Methods: This was a retrospective study where hospital records of patient's ≥13 years undergoing elective surgeries at a tertiary hospital in Zaria over a period of 6 months were reviewed. Patients' ages, gender, preoperative PCV, category of surgery, American Society of Anesthesiologists (ASA) scores, and number of units of blood transfused intraoperatively were analyzed using SPSS 20.0.
Results: There were 164 surgeries conducted during the study period. Females constituted 96 (58.5%) of the patients. The mean age and preoperative PCV were 38.9 ± 14.9 years and 36.6 ± 4.9%, respectively. The median (interquartile range) units transfused intraoperatively and ASA scores were 0 (0) and 2 (0), respectively. Spearman's correlation to compare the number of units transfused as a reference point was significant for preoperative PCV (ρ = −0.222, P = 0.004). Regression analyses using category of surgery, ASA scores, age, and preoperative PCV predicted intraoperative transfusion; F(2, 161) = 5.120, P = 0.007, adjusted R2 = 0.048 with preoperative PCV and category of surgery predicting the number of units transfused (β =-0.176, P = 0.023) and (β = −0.158, P = 0.041), respectively.
Conclusion: Preoperative PCV and category of surgery although important have a low ability to predict the number of blood units transfused intraoperatively.
