Background: Foreign body Aspiration is a life threatening emergency situation among pediatric age group worldwide. Early intervention is crucial to save lives. Objective: The aim of this study is to determine magnitude of adverse events and outcome of foreign body aspirations removal among pediatric patients at TASH. Materials and Methods: Institution based Prospective; observational study was conducted among 60 foreign body aspiration cases with census sampling technique. Standard structured observational tool was used. Data cleaned and entered to Epi data version 3.1 and exported to SPSS version 26. Descriptive and Chi square and Fisher Exact test were done. Result- A total of 60 FBA cases were studied in 56 patients. Four of the cases were repeat procedure. The commonest adverse event encountered was desaturation 51(85%) followed by one lung ventilation 45 (75%), persistent hypoxia 34(56.7%), air way mucosal bleeding 34(56.7%), laryngospasm 14 (23.3%), air way or laryngeal edema 13(21.7%), bradycardia 9(15%), esophageal intubation 5(8.3%) and inadequate depth of anesthesia 2(3.3%). There were 2 cases of tracheobronchial fistula with tension pneumothorax. Among the study participants 7 patients needed PICU admission. There was no death. Mode of ventilation, duration of surgery, surgeon experience, and occurrence of adverse events such as Laryngeal edema, persistent hypoxia and bradycardia had statistically significant association with PICU admission. Conclusion- The incidence of adverse events, DOS and DOA were higher in comparison to any other researches. The incidence of serious complication is also higher than other researches and surgeon experience also had significant risk factors for patient disposition of PICU transfer.
