The Effect of Different Concentrations of Epinephrine in Otoendoscopic Surgery on Surgical Field Clarity: A Double-Blind, Randomized Study.

ABSTRACT:

Importance

At present, there is no consensus on the concentration of epinephrine/physiological saline for subcutaneous injection into external auditory canal (EAC) under general anesthesia in otoendoscopic surgery. A randomized controlled trial (RCT) research is needed to provide reference, as this concentration can provide satisfactory surgical field clarity while maintaining patients' hemodynamic stability.

Objective

Comparison of the effect of subcutaneous injection of different concentrations of epinephrine/physiological saline into EAC under general anesthesia in otoendoscopic surgery on surgical field clarity and hemodynamics.

Design

This double-blind, RCT study was about the effect of topical epinephrine injection in otoendoscopic surgery.
