Nebulized Versus Intravenous Tranexamic Acid on Surgical Field Quality in Patients Undergoing Endoscopic Sinus Surgeries

Intraoperative bleeding is one of the vital problems for anesthesiologists and surgeons, during endoscopic nasal surgery; where the surgical field is very limited and surrounded by vital structures. The tinniest amount of blood in such surgical field can obscure the anatomy and clog the tip of the endoscope, requiring repeated irrigations and suctioning; both of which have traumatic effects on the friable nasal mucosa. Anesthetic techniques to minimize bleeding during endoscopic nasal surgery are of primary importance for a safe and effective procedure, reducing operative time and shortening post-operative recovery. Good surgical conditions could be achieved with systemic, topical, or regional anesthetic techniques. The use of topical and regional techniques has been gaining popularity in recent years as an alternative to the administration of heavy premedication, high narcotic doses, intravenous lignocaine, clonidine, calcium channel blockers, sodium nitroprusside, beta-adrenergic blockers, and magnesium sulfate, which may produce a lack of alertness, respiratory depression, hypoxia, nausea and vomiting, and delayed recovery. Recent studies have shown that the use of tranexamic acid could be a safe and effective management option for hemostasis in a wide range of specialties. Tranexamic acid (TXA) is a synthetic lysine derivative that blocks the lysine binding site on plasminogen, thus inactivating its conversion to plasmin and hence attenuating its fibrinolysis effects.
