Predicting Operative Blood Loss During Spinal Fusion for Adolescent Idiopathic Scoliosis

Abstract

Retrospective study: Level II.

Influence of curve magnitude and other variables on operative time, blood loss and transfusion requirements in adolescent idiopathic scoliosis

“…Larger preoperative curve magnitudes were also associated with longer fusion segments and increased operative time. These findings are consistent with other studies showing greater blood loss with higher numbers of fused vertebrae and longer duration of surgery, particularly when more osteotomies are performed [8,16,[24][25][26][27]. Overall, the current study's findings strongly indicate that the severity of the deformity (measured by the preoperative Cobb angle) is predictive of the need for perioperative blood transfusion.…”

Comparison of combined anterior–posterior approach versus posterior-only approach in treating adolescent idiopathic scoliosis: a meta-analysis

“…On the basis of our inclusion criteria and exclusion criteria, 10 articles were finally selected into this meta-analysis including three nonrandomized prospective studies [17][18][19] and seven retrospective studies [14,[20][21][22][23][24][25]. The detail of study selection and basic characteristics of included studies are shown in Fig.…”

“…Data of blood loss and operative time were available in three articles [19,24,25] and length of hospital stay in two articles [19,24]. Data analysis revealed that there was significantly less blood loss in P group than in AP group with moderate heterogeneity (95 % CI 363.28-658.91, P \ 0.00001; I 2 = 50 %; Fig.…”

Effect of intraoperative autologous transfusion techniques on perioperative hemoglobin level in idiopathic scoliosis patients undergoing posterior spinal fusion: A prospective randomized trial

“…These may be patient factors such as gender, skeletal maturity, Cobb angle, kyphosis, activated partial thromboplastin time level and fibrinogen level, and menstruation cycle phase [15][16][17][18][19] or surgery-related, number of fusion level, operative time, stages of surgery, number of osteotomies, and surgical approach. 2,15,17,[19][20][21][22][23] Some of the above factors such as number of vertebral levels fused, number of screws inserted, duration of surgery, and Cobb angle demonstrated positive correlation with total blood loss in our study. Recently, a dual surgeon approach was also reported to result in shorter operative time, less blood loss, and lower risk of allogenic blood transfusion.…”
