Randomized Controlled TrialImproved quality of surgical field during endoscopic sinus surgery after clonidine premedication--a pilot study.
Inadequate surgical field visualization due to intraoperative bleeding during endoscopic sinus surgery (ESS) can cause major complications. The aim of this prospective study was to compare the effect of preoperative administration of clonidine and melatonin on the quality of the surgical field visualization and selected aspects of presurgical premedication. ⋯ Premedication with clonidine before ESS provides better quality of surgical field and more favorable hemodynamic profile as compared to melatonin.
