Risk factors associated with reintubations in children undergoing foreign body removal using flexible bronchoscopy: a single-center retrospective cross-sectional study

Abstract

BackgroundReintubation is a severe complication during foreign body (FB) removal that uses flexible bronchoscopy.ObjectiveTo investigate the incidence and risk factors for reintubations in children undergoing FB extraction by flexible bronchoscopy in a single center.DesignA retrospective cross-sectional study.SettingAll children with foreign body aspiration at Fujian Maternity and Child Health Hospital, Affiliated Hospital of Fujian Medical University from January 2015 to December 2020.PatientsChildren with FB removal using a flexible bronchoscopy were enrolled in the trial according to the inclusion criteria.MeasurementsBoth multivariable and logistic regression analyses were used to analyze the association between characteristic data and reintubations. The results were presented as odds ratios (ORs) with 95% confidence intervals (CIs).ResultsIn total, 244 patients met with the inclusion criteria and were included in the analysis. Among those participants, 28 children (11.5%) underwent reintubations after FB removal by flexible bronchoscopy. Independent factors associated with reintubations were identified as operative time ≥ 60 min [OR: 3.68, 95% CI (1.64–8.82)] and ASA ≥ III [OR: 5.7, 95% CI (1.23–26.4)].ConclusionsChildren undergoing FB removal by a flexible bronchoscopy may encounter with a high incidence of postoperative reintubations. Both long operative duration and a severe physical status cause a growing risk of reintubations.
