Abstract

Background: Flexible fiberoptic bronchoscopy (FOB) is used to diagnose and plan various respiratory diseases. During FOB, the peripheral oxygen value can decrease, increasing the risk of respiratory failure. Our aimed to evaluate the main indications and safety of FOB applied to patients with low, moderate, and high SO₂ in our clinic.

Methods: In this single-centre retrospective study conducted in our clinic between 2016 and 2022, a power analysis was performed on 1512 patients who underwent FOB. As a result of the analysis, three groups of 67 people, each with low, medium, and high SO₂, were formed. FOB was performed on 201 patients with low oxygen saturation (SO₂<87%), medium oxygen saturation (87%<SO₂<93%), and high oxygen saturation (SO₂>92). The indications for the FOB procedure and the changing SO₂ values before and after the procedure were uploaded to the SPSS program (Statistical Package for Social Sciences for Windows version 25 software). Since the patients' values did not show normal distribution, the data of the three groups were compared in pairs by applying the Mann-Whitney U Test.

Results: The mean age of the patients was 67 years ± 12.4 years. Patients underwent bronchoscopy for multiple reasons, such as mass 37.3%), parenchymal infiltration (26.4%), atelectasis (10.4%), chronic cough (5%), resistant bronchospasm (7.5%), tuberculosis (3%), haemoptysis (2.5%), and sarcoidosis (1.5%), and lymphoma (1.5%).

Complications had been seen in our patients after bronchoscopy are as follows; 1% massive haemoptysis, 5.97% arrhythmia, 3.48% pneumonia, 1% pneumothorax, 7.96% mucosal haemorrhage, 2.49% hypertension, 0.5% hypotension, and 7.96% epistaxis. 

Mann-Whitney U Test was applied to all three groups, and no significant difference was found between smoking in pairs (p > 0.05). When comparing the SO₂ differences of the groups with no difference in smoking, significant differences were found between Groups: I and II, Groups II and III, and Groups I and III (p < 0.05).

Conclusion: Regardless of the level of SO₂, although there are problems that may develop in patients undergoing bronchoscopy, the risks that may develop before and after the procedure can be easily controlled with simple, predictable interventions by monitoring.
