Background and Goal of Study: Airway foreign body aspiration is a risk in children, especially under the age of 3.  Early removal of the foreign body by rigid bronchoscopy is crucial, but complications during the procedure may develop. 
One of the most frequent complications is hypoxemia   (1). The goal of this study was to evaluate the appearance of complications during the anesthetic management of airway foreign body aspiration and also compare groups in what concerns to intraprocedural complications development. 
Materials and Methods: We retrospectively reviewed all cases of rigid bronchoscopy anesthetic management (urgent and elective) of children from January 2012 to March 2017. Patients with complications were compared to those without them. The studied variables were gender, age, weight, elective or urgent surgery, ASA physical status, duration of the foreign body in the airway, ventilation mode, type of anesthesia, foreign body location, duration of the procedure, time to emerge from anesthesia and successful foreign body removal. Continuous variables were compared with the MannWhitney test and categorical ones with the χ2 -test.
Results and Discussion: 36 patients were included in the study with a mean age of 4,2 years. Among the 36 children, 2 developed complications, including hypoxemia (N=1) and cardiac arrest (N=1). The other showed no reported incidents. From all considered variables, ASA physical status (I, II or IV) and ventilation mode (manual jet ventilation, automatic jet ventilation, controlled ventilation) were statistically significant between both groups. Other factors, such as gender, age, weight, elective or urgent surgery, duration of the foreign body in the airway, ventilation mode, type of anesthesia, foreign body location, duration of the procedure, time to emerge from anesthesia and successful foreign body removal were not significantly different between both groups.
