Safe and Effective Performance of Pediatric Spinal Deformity Surgery in Patients Unwilling to Accept Blood Transfusion: A Clinical Study and Review of Literature

Résumé

Abstract Background: Pediatric deformity surgery traditionally involves major blood loss. Patients refusing blood transfusion add extra clinical and medicolegal challenges; specifically the Jehovah’s witnesses population. The objective of this study is to review the safety and effectiveness of blood conservation techniques in patients undergoing pediatric spine deformity surgery who refuse blood transfusion Methods: After obtaining institutional review board approval, we retrospectively reviewed 20 consecutive patients who underwent spinal deformity surgery and refused blood transfusion at a single institution between 2014 and 2018.We collected pertinent preoperative, intraoperative and most recent clinical and radiological data with latest follow-up (minimum two-year follow-up).Results: Twenty patients (13 females) with a mean age of 14.1 years were identified. The type of scoliotic deformities were adolescent idiopathic (15), neuromuscular (3) and congenital (2). The major coronal Cobb angle was corrected from 55.40 to 11.20 (80% correction, p< 0.001) at the latest follow-up. A mean of 11.4 levels were fused, 5.6 levels of Pontes osteotomies and 2.8 levels of thoracoplasty performed. 1 patient underwent L1 VCR and 3 patients had fusion to pelvis. Estimated blood loss and cell saver returned an average of 307.9 ml and 80ml, respectively. Operative times average at 214 min. The average drop in hemoglobin after surgery was 2.1mg/dl. The length of hospital stay averaged 5.1 days. There were no intraoperative complications. Three postoperative compilations were identified, none related to their refusal of transfusion. One patient had in-hospital respiratory complication, one patient developed a late infection, and one patient developed asymptomatic radiographic distal junctional kyphosis.Conclusions: Blood conservation techniques allow safe and effective spine deformity surgery in pediatric patients refusing blood transfusion without major anesthetic or medical complications.Level of Evidence: Level IV.
