Flexible bronchoscopy is an indispensable complementary exam in respiratory medicine for both diagnosis of many pulmonary diseases and their treatment. Only a few studies in literature have been conducted to evaluate the safety and acceptability of this act.
Prospective, mono-center, non-comparative study involving 120 patients who underwent a flexible bronchoscopy for diagnostic.
During the study, flexible bronchoscopy has caused neither deaths nor major complications. However, minor incidents have been deplored: hemoptysis (13.3%), epistaxis (3.3%), desaturation less than 90% (4.2%), laryngospasm (3.3%) and vagal discomfort (1.7%). 56.7% of patients were anxious before the exam and 24% of patients preferred to have general anesthesia. The patients reported cough in 78.3% of cases, difficulty in breathing in 55% of cases and pain in 13.3% of cases. The occurrence of nausea, noted in 15.8% of cases, was correlated with the pathway of the bronchoscope (P=0.002). At the end of the endoscopy, 67.5% of patients agreed to repeat the examination, if necessary, under the same conditions.
The results of our study confirm that many complications during a flexible bronchoscopy are rare and generally mild failing in life-threatening. However, the occurrence of discomfort (cough, pain, vomiting, dyspnea) or incidents (asphyxia, vagal discomfort, laryngeal spasm) are likely to alter patient comfort during the exam.
