Abstract
PURPOSE: The aim of the present study is to investigate whether acute normovolemic hemodilution (ANH) can reduce the frequency and amount of perioperative allogeneic blood transfusion (ABT) (intraoperative ABT and postoperative ABT until discharge from the hospital) in pediatric and adolescent scoliosis surgery. METHODS: This single-center, retrospective, observational study included the perioperative data of 147 patients who were 18 years old or younger and underwent scoliosis surgery. Patients were divided into groups according to whether they received ANH: i.e., an ANH group and control group. Propensity-score-adjusted multivariable logistic regression analysis was performed to determine whether ANH can reduce the frequency of perioperative ABT. RESULTS: A total of 125 patients were analyzed, 95 and 30 in the ANH and control group, respectively. The intraoperative/postoperative ABT frequency was significantly lower in the ANH group than in the control group (17.9% vs. 36.7%, p = 0.044). The amount of ABT [median (IQR): 0 (0, 0) mL/kg vs. 0 (0, 16.3) mL/kg, p = 0.033] was also significantly lower in the ANH group than in the control group. Propensity-score-adjusted multivariable logistic regression analysis indicated that ANH use [odds ratio: 0.15; 95% confidence interval: 0.03, 0.77; p = 0.023)] was associated with a lower risk of ABT after adjusting for intraoperative blood loss and duration of surgery. CONCLUSION: ANH use can reduce the frequency and amount of perioperative ABT in pediatric and adolescent scoliosis surgery.
