Predictors of unexpected hospital admissions after outpatient endoscopic sinus surgery: retrospective review.

Abstract

Unexpected admissions following ESS are infrequent, and the reasons for admission are varied. In this study, although 9 of the 11 parameters evaluated showed no statistical significance as independent predictors of unexpected admissions, 2 did approach statistical significance. Intuitively, the presence of patient comorbidities would be expected to place the patient at greater risk of unexpected admission. Ondansetron is a potent antiemetic and is reserved for patients at risk or in those having severe symptoms. These patients would also be expected to have an increased risk of an unanticipated hospital stay.
