Effect of single-dose intravenous tranexamic acid on postoperative nasal bleed in septoplasty

Postoperative nasal bleeding is a common complication of septoplasty and may lead to painful procedure of nasal packing to stop bleeding. Since Tranexamic acid (TXA) has been reported to reduce bleeding, the purpose of this study is to investigate the effect of single dose of intravenous TXA on postoperative nasal bleed associated with septoplasty.

This prospective randomized, double-blinded clinical trial consisted of 176 patients aged 18-55 years who underwent septoplasty for symptomatic deviated nasal septum. These participants were randomly divided into 2 groups; 88 patients were given normal saline (Control group) and 88 patients were administered a single shot of intravenous TXA 10mg/kg (TXA group). Operative technique applied was same in all cases. At the end of surgery nasal packs, nasal splints or trans-septal suturing were not done. Nasal bleeding was monitored after surgery and up to 2 weeks postoperatively.

Patients receiving TXA showed significantly less postoperative nasal bleeding compared with controls. Extensive bleeding in terms of number of gauze pads used and duration was also higher in placebo with a statistically significant difference (all P=<0.05). Seven patients required nasal packing in control group to stop bleeding as compared to one patient in TXA group. Adverse reactions to TXA were minimal, and these were easily managed conservatively.

Single intravenous dose of TXA is shown to be effective and safe agent in preventing postoperative nasal bleeding after septoplasty therefore avoiding additional techniques of nasal packing, intranasal splint or trans-septal suturing during surgery.
