Background
Functional endoscopic sinus surgery (FESS) is a common procedure for the treatment of chronic sinusitis and minimal bleeding inside the narrow surgical field affects the surgical visualization, prolongs operative time, and increases ocular and intracranial injuries. Our study aims to evaluate and compare the effectiveness of oral versus intravenous Tranexamic acid on surgical field bleeding in endoscopic sinus surgery.
Methods
A prospective, randomized, controlled trial enrolled 159 participants (ASA I-II, both sex and age 18–40 years) undergoing FESS who were equally randomized into 3 groups. Group O received 2 gm of TXA orally 2 hours before surgery, Group I received 15 mg/kg of IV TXA slowly after induction of anesthesia, and Group C didn’t receive any. Intraoperative surgical field bleeding was assessed by the Wormald grading scale and Surgeon satisfaction on a 5-point Likert scale. At 24 hours post-operatively, the incidence of nasal bleeding, PONV, and D-dimer level were recorded.
Results
Showed significantly higher surgical field score, duration of surgery, recovery time, and postoperative (24 hours) D-dimer in group-C (p-value <0.001) with no difference between groups-I and O, while surgeon satisfaction was significantly lower in group-C (p-value <0.001) with no difference between groups-I and O. No differences regarding hemodynamic parameters, postoperative bleeding, pain, and PONV were found.
Conclusions
Oral TXA was safe, cheap, and as effective as IV TXA regarding surgical field visualization, surgeon satisfaction, and operative time during FESS; with limited adverse effects and no evidence of thromboembolic complications.
