Group 1Tranexamic Acid
Tranexamic acid 100 mg/ml; 50 mg/kg loading dose = 0.5 ml/kg LD given over 15 minutes and 10 mg/kg/hr = 0.1 ml/kg/hr infusion for the duration of the surgery.~Tranexamic Acid: Following a standardized general anesthetic protocol, patients coming with idiopathic scoliosis will be randomized to either:~1. placebo i.e. saline 0.9% (intravenous injection)~2. intravenous TXA given as a loading dose over 15 minutes of 50 mg/kg bolus ( within an hour prior to surgical incision) and 10 mg/kg/hr infusion for the duration of the surgery.

Placebo ( 0.9% Normal saline) intravenously given as a 0.5 ml/kg loading dose over 15 minutes followed by a 0.1 ml/kg/hr continuous infusion throughout the surgery.~Placebo: Following a standardized general anesthetic protocol, patients coming with idiopathic scoliosis will be randomized to:~1. Placebo ( 0.9% Normal saline) intravenously given as a 0.5 ml/kg loading dose over 15 minutes followed by a 0.1 ml/kg/hr continuous infusion throughout the surgery or~2. TXA as previously described.
