Evaluating real-time effects of topical 1:1000 epinephrine in endoscopic sinus and skull-base surgery on hemodynamic parameters through intraoperative arterial line monitoring

Background

Administration of topical 1:1000 epinephrine is commonly used in practice to achieve vasoconstriction during endoscopic sinus surgery and skull-base surgery; however, real-time effects on cardiovascular changes from systemic absorption have not been well studied.

Methods

Twenty-six patients undergoing endoscopic transsphenoidal resection of a pituitary lesion at a single institution were included into the study. Following arterial line placement by anesthesiology, 6 cottonoid pledgets soaked in 1:1000 epinephrine were placed into the bilateral nasal passages. Hemodynamic parameters including heart rate, blood pressure, and mean arterial pressure were collected at baseline, 30 seconds, and increments in minutes up to 10 minutes. Additional potentially confounding factors such as use of antihypertensives, stress dose steroids, and positioning with head pins were all performed following termination of data collection.

Results

The majority of patients (20/26, 77%) showed no significant change in any parameter following placement of epinephrine soaked cottonoids. Six patients, however, had transient increases in blood pressure following administration of topical epinephrine, with a few requiring vasodilatory interventions. Return to baseline cardiovascular values were noted after an average of 7 minutes. There was no correlative preoperative characteristic that predicted sensitivity to placement of epinephrine. There were no lasting or permanent effects.

Conclusion

Although intranasal topical 1:1000 epinephrine use showed no substantial hemodynamic changes in the majority of patients, in a subset of patients it can cause significant transient elevations in blood pressure to a degree necessitating intervention. Topical epinephrine should be used judiciously in endoscopic sinus surgery.
