predictors transfusion Adolescent Idiopathic Scoliosis

Shobhit V Minhas, Ian Chow, Joseph Bosco, Norman Y Otsuka
STUDY DESIGN: Retrospective cohort study. OBJECTIVE: To determine predictors of and 30-day complications associated with blood transfusion volume after posterior spinal fusion for adolescent idiopathic scoliosis (AIS). SUMMARY OF BACKGROUND DATA: Posterior arthrodesis is a common procedure performed for AIS, and patients frequently require perioperative blood transfusions. Few studies, however, have examined the rates and potential complications associated with blood transfusion volume...

BACKGROUND: Posterior spinal instrumentation and fusion for correction of adolescent idiopathic scoliosis (AIS) typically requires lengthy operating time and may be associated with significant blood loss and subsequent transfusion. This study aimed to identify factors predictive of duration of surgery, intraoperative blood loss and transfusion requirements in an Irish AIS cohort. METHODS: A retrospective review of 77 consecutive patients with AIS who underwent single-stage posterior spinal instrumentation and fusion over a two-year period at two Dublin tertiary hospitals was performed...

STUDY DESIGN: Analysis of population-based National Hospital Discharge Survey data collected for the Nationwide Inpatient Sample. OBJECTIVE: To examine the predictors of allogeneic blood transfusion (ALBT) in spinal fusion for pediatric patients with idiopathic scoliosis. SUMMARY OF BACKGROUND DATA: Spinal fusion for pediatric patients with idiopathic scoliosis is associated with major blood loss and often necessitates ALBT. METHODS: The Nationwide Inpatient Sample was used to identify pediatric patients with idiopathic scoliosis who underwent spinal fusion from 2004 to 2009, using the International Classification of Diseases, Ninth Revision, Clinical Modification codes...

BACKGROUND CONTEXT: Previous studies have shown that modern intraoperative blood-saving techniques dramatically reduce the allogeneic transfusion requirements in surgery for adolescent idiopathic scoliosis (AIS). No studies have looked at the pattern of postoperative hemoglobin (Hb) in AIS patients undergoing corrective spinal surgery and correlated this with the timing of allogeneic transfusion. PURPOSE: To describe the pattern of perioperative blood loss in instrumented surgery for AIS...

BACKGROUND: Numerous studies have reported on post- operative infection following spinal arthrodesis for spinal deformity. The incidence of infection associated with spinal surgery overall ranges from less than 1% to 15%. Certain factors may increase the risk of surgical site infection (SSI) in patients who undergo surgical treatment for spinal deformities. These include a diagnosis of neuromuscular disease, use of surgical drain or lack thereof, patient comorbidities, increased blood transfusions, and an allergic inflammatory response to the use of instrumentation...

BACKGROUND: The treatment of patients with large adolescent idiopathic scoliosis curves has been associated with increased surgical complexity. The purpose of this study was to determine whether surgical correction of larger adolescent idiopathic scoliosis curves increased the utilization of health-care resources and to identify potential predictors associated with increased perioperative health-care resource utilization. METHODS: A nested cohort of patients with adolescent idiopathic scoliosis with Lenke type 1A and 1B curves were identified from a prospective longitudinal multicenter database...
