Frecuencia de complicaciones durante fibrobroncoscopia con soporte con ventilación de alto flujo. Hospital Vicente Corral Moscoso, 2019

Abstract

Background: Bronchoscopy is a procedure that allows to observe bronchial tracheo tree for diagnostic and therapeutic purposes. The bronchoscope added to the use of sedation can produce respiratory and hemodynamic complications. These complications can cause an interruption of the procedure. High-flow oxygen therapy decreases breathing work and dead space, better tolerance to high oxygen flow administration. Objective: Determine the frequency of complications during fiber bronchoscopy with high flow oxygen therapy support. Methodology: Observational and prospective study that investigates high flow oxygen therapy benefits during bronchoscopy and complications reduction. Variables measured: heart rate, respiratory rate, MAP, Sat O2, FiO2, PaO2, PaCO2, PaO2/FiO2 index, desaturation time, patient and operator comfort, success rate of bronchoscopy. Probabilistic analyzes were performed with SPSS biostatistical program 23th version. Results: Bronchoscopy was performed on 20 patients from intensive care unit, it was observed that 30% of patients desaturated in the procedure and saturation variations were 2.7% ± 1.94; 25% had blood pressure alterations and 20% had tachycardia. Average duration of bronchoscopy was 7:44 min ± 2:06 with very good patient tolerance and operator comfort. Conclusion: High flow fibrobroncoscopy has very good comfort for operator and patient due to low frequency of complications and saturation variation compared to studies without high flow.
