NCT01451788

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Total perioperative blood loss

    Total blood loss during surgery + drain output, millilitres

    Surgery time (up to 8 hours) + first postoperative 24 hours

Secondary Outcomes (3)

  • Used blood products

    Surgery time (up to 8 hours) + first 24 hours postoperatively

  • Blood loss during surgery

    up to 8 hours

  • Time of surgery

    up to 8 hours

Study Arms (2)

Conventional group

NO INTERVENTION

conventional blood saving methods (use of bone wax for cancellous bony bleeding; bipolar diathermy and epidural space packing for epidural venous bleeding)

Floseal

EXPERIMENTAL

Gelatin matrix with human derived thrombin (Floseal) used in adolescents undergoing posterior spinal deformity surgery for adolescent idiopathic scoliosis (AIS)

Device: Gelatin matrix with human derived thrombin (Floseal, Baxter)

Interventions

Floseal will be used to stop cancellous bone bleeding, pedicle channel bleeding or epidural space bleeding by injecting suitable amount of this matrix and irrigating it away after few minutes.

Also known as: Floseal, Baxter
Floseal
