Abstract

STUDY DESIGN:

A retrospective study.

OBJECTIVE:

To investigate the effectiveness and safety of intravenous tranexamic acid for reducing perioperative blood loss in patients with multilevel thoracic spinal stenosis (TSS).

METHODS:

This is a retrospective observational study of 42 patients with multilevel TSS admitted from December 2016 to October 2017 to the spine department of Honghui Hospital who underwent posterolateral bone graft fusion with posterior laminectomy and decompression fixation. The patients were divided into 2 groups. All the surgeries were completed by the same surgeon. Group A received an intravenous infusion of 15 mg/kg 15 min prior to surgery. Continuous infuse on of tranexamic acid (TXA) at a dose of 1 mg/kg/h was provided throughout the operation until the skin was closed. Group B received no TXA as a blank control group. Group A comprised 10 males and 10 females with an average age of 53.41 ± 7.93 years; group B comprised 11 males and 11 females with an average age of 55.10 ± 8.43 years. The need for blood transfusion, volume of blood transfusion, blood coagulation function, extubation time, postoperative hospital stay and incidence of postoperative deep venous thrombosis (DVT) were recorded during and after the operation for the 2 groups.

RESULTS:

There was no significant difference between the 2 groups in general characteristics, such as age, sex and body mass index (BMI) (P > .05). There was no significant difference between the 2 groups in the levels are instrumented and the laminectomy levels in each group. The average postoperative blood loss, need for blood transfusion, time to postoperative extubation and length of postoperative hospital stay in group A were lower than those in group B, and there was a significant difference between the 2 groups (P < .05). The preoperative and postoperative coagulation, and postoperative DVT did not occur 48 h after operation.

CONCLUSION:

In the treatment of multilevel thoracic spinal canal stenosis using trabeculectomy with posterior laminectomy and posterolateral bone graft fusion, TXA can reduce the amount of blood transfused and the need for blood transfusion and can shorten the extubation time and the length of postoperative hospital stay without increasing the incidence of postoperative coagulation dysfunction or postoperative DVT.
