Risks factors and regression model for risk calculation of anesthesiologic intervention in topical and intracameral cataract surgery

Abstract

Purpose: To determine risk factors for anesthesiologist intervention during routine cataract surgery performed with topical and intracameral anesthesia and establish a regression model to identify high-risk patients. Setting: Department of Ophthalmology, Clínica Universidad de Navarra, Pamplona, Spain. Design: Prospective case series. Methods: After cataract surgery at an ambulatory surgical center, anesthesia personnel completed a questionnaire to determine adverse medical events and risk factors related to anesthesiologist intervention. A Poisson regression model was used to calculate the interventional risks. Bootstrapping was performed for internal model validation. Results: Of the 1010 cases, 50 (4.95%) required anesthesiologist intervention. Univariate analysis identified an association between anesthesiologist intervention and hypertension (P
