Abstract

Rigid bronchoscopy is an invaluable tool of interventional pulmonology. Performing rigid bronchoscopy requires professional skills. Successful intubation is the first challenge, and providing enough oxygenation is important for intubation because of patient’s condition of general anesthesia and paralysis. This research reported the clinic experiences of using nasopharyngeal tube to provide ideal oxygenation during rigid bronchoscope intubation. 11 patients received 12 rigid bronchoscope operations. Among them, nine patients were pulmonary carcinoma patients, one suffered from bronchiectasis with the combination of massive hemoptysis, one was tuberculosis patient who got the right intermediate bronchus stenosis. There were three cases whose intubation of rigid bronchoscope failed. The intubation time of other nine successful cases was 3.19±1.43 minutes. The average oxygen saturation (SaO2) of 12 cases was 97.8%±1.4% (ranged from 95% to 100%). End-tidal carbon dioxide pressure (EtCO2) was 40.1±7.4 mmHg (from 31 mmHg to 58 mmHg). During rigid bronchoscope intubation, heart rate (HR), diastolic blood pressure (DBP), systolic blood pressure (SBP) was recorded as 80.2±10.9, 72.2±8.2 mmHg, 135.4±10.4 mmHg. We concluded that oxygenation via nasopharyngeal tube was a safe, easy, and effective method for supporting oxygenation during rigid bronchoscope intubation.
