Predictors for Massive Blood Loss During Posterior Correction of Congenital Scoliosis in Pre-school Children:A Retrospective Observation.

Abstract

Objective To investigate the predictors for massive blood loss during posterior correction of congenital scoliosis in pre-school children. Methods Totally 124 children under six years of age,who received posterior correction of congenital scoliosis,were divided into two groups according to the ratio of intraoperative blood loss (BL) and estimated blood volume (EBV). Massive blood loss was defined as BL/EBV>0.15,and minor or moderate blood loss as BL/EBV≤0.15. All the records,including demographics,intraoperative fluids,pre- or postoperative laboratory parameters,and the length of hospital stay,were compared between these two groups. Results There were 57 children in the moderate or minor blood loss group and 67 children in the massive blood loss group. When compared with moderate or minor blood loss group,children in massive blood loss group had significantly lower body weight,shorter body height,longer anesthesia period,and more autologous or allogeneic transfusion (P<0.05). Binary Logistic regression analysis showed that body weight lower than 15 kg was the independent predictor for massive blood loss (OR=0.435,95% CI=0.197-0.962). Conclusions The incidence of massive blood loss is about 54% in children under six years of age who have received posterior correction of congenital scoliosis. The body weight of lower than 15 kg is an independent predictor for massive blood loss during the surgery.
