[Progress on the application of tranexamic acid in adolescent spine corrective surgery]

To review the advances in the application of tranexamic acid (TXA) in adolescent spinal corrective surgery.

The mechanism of action and pharmacokinetic, effectiveness, dosage, safety as well as methods of administration were comprehensively summarized by consulting domestic and overseas related literature about the application of TXA in adolescent spinal corrective surgery in recent years.

TXA efficaciously reduce intraoperative blood loss, transfusion rate and volume, postoperative drainage volume in adolescent spinal corrective surgery. At present, the most common method of administration in adolescent spinal corrective surgery is that a loading dose is given intravenously before skin incision or induction of anesthesia, followed by a maintenance dose until the end of the surgery. The range of loading dose and maintenance dose is 10-100 mg/kg and 1-10 mg/(kg·h), respectively. No drug related adverse event has been reported in this range.

The effectiveness and safety of TXA in adolescent spinal surgery have been basically confirmed. However, further studies are needed to determine the optimal dosage, method of administration as well as whether it could reduce blood loss after surgery.
