Abstract:
Objective:To identify the risk factors for massive blood loss in pediatric patients with congenital scoliosis undergoing posterior hemivertebra resection.Methods:The clinical data of pediatric patients with congenital scoliosis who underwent posterior hemivertebra resection in our hospital from May 2017 to July 2019 were collected.The children were divided into group A (massive blood loss, blood loss/blood volume ≥30%) and group B (non-massive blood loss, blood loss/blood volume <30%) according to intraoperative blood loss.Logistic regression analysis was used to stratify the risk factors.Results:A total of 108 pediatric patients were enrolled in the study including 29 cases in group A and 79 cases in group B, respectively.There were significant differences in the preoperative Cobb angle, body mass index, the number of fused levels, the number of screws and operative time between the two groups ( P<0.05). Logistic regression analysis showed that the preoperative Cobb angle, operative time, the number of fused levels and body mass index were the risk factors for intraoperative massive blood loss ( P<0.05). Conclusion:Lower BMI, larger Cobb angle, increased operative time and more fused levels are the risk factors for massive blood loss in pediatric patients with congenital scoliosis undergoing posterior hemivertebra resection.
