简要总结
The Finnish Paediatric Orthopaedic Study Group will perform a prospective randomized, multicenter, clinical trial comparing Gelatin matrix with human derived thrombin (Floseal, Baxter) and without use of Floseal in adolescents undergoing posterior spinal deformity surgery for AIS (adolescent idiopathic scoliosis between 45 and 90 degrees) in Turku, Tampare and Helsinki Children's Hospitals. Sixty patients will be randomized into the intervention group receiving Floseal (n=30) and control group not receiving Floseal (n=30). Each University Hospital will treat 10 Floseal and 10 conventional treated scoliosis patients (block randomization). Both treatment groups will be allowed to use conventional blood saving methods.
详细描述
Background: Posterior spinal deformity surgery can be associated with major blood loss, especially from cancellous bone or epidural venous plexus. Products such as Gelatin Matrix with bovine derived thrombin (Floseal) can be used to prevent blood loss in adult patients undergoing spine surgery.
Aim: To document and compare effectiveness of Gelatin matrix with human derived thrombin with conventional blood loss control methods in adolescents undergoing posterior spinal deformity surgery for adolescent idiopathic scoliosis (AIS), who do not need vertebral column resection.
Methods: The Finnish Paediatric Orthopaedic Study Group will perform a prospective randomized, multicenter, clinical trial comparing Gelatin matrix with human derived thrombin (Floseal, Baxter) and without use of Floseal in adolescents undergoing posterior spinal deformity surgery for AIS (adolescent idiopathic scoliosis between 45 and 90 degrees) in Turku, Tampere and Helsinki Children's Hospitals. Sixty patients will be randomized into the intervention group receiving Floseal (n=30) and control group not receiving Floseal (n=30). Each University Hospital will treat 10 Floseal and 10 conventional treated scoliosis patients (block randomization). Both treatment groups will be allowed to use conventional blood saving methods.
Main outcome measures:
Blood loss during surgery (millilitres) Drain output during 24 hours (millilitres) Total blood loss (Blood loss during surgery + drain output, millitres) Used blood products (Red cell, frozen plasma, and thrombocyte units) Time of surgery Hospital stay Cost benefit analysis (blood product use, surgical time, hospital stay) Complications related to use of Floseal as a secondary outcome measure.
