摘要
Objective: This study was to explore the application of new endoscopic nasal mask in painless fiberoptic bronchoscopy, and investigate a safe, comfortable, convenient, economic and easy anesthesia for clinical fiberoptic bronchoscopy. Methods: Sixty patients undergoing fiberoptic bronchoscopy during intravenous anesthesia with dexmedetomidine and low dose propofol were randomly assigned to nasal catheter oxygen supply group (Group A) and new endoscopic nasal mask oxygen supply group (Group B). Mean arterial pressure (MAP), heart rate (HR) and blood oxygen saturation (SPO2) were recorded before anesthesia (T-0), after anesthesia (T-1), immediately after insertion of fiberoptic bronchoscope into the airway (T-2), immediately after fiberoptic bronchoscope contacting tracheal carina (T-3), during fiberoptic bronchoscopy (T-4), and 5 minute after withdrawal of fiberoptic bronchoscope (T-5). Results: MAP in both groups decreased at T-1 and T-5, and HR in both groups decreased at T-1-T-5 as compared to those at T-0. SpO(2) in Group A decreased at T-1-T-4 as compared to that at T-0; SpO(2) in Group A at T-1 similar to T-4 was lower than that in Group B. The proportion of patients who needed lifting of the jaw or mechanical ventilation in Group A was higher than that in Group B. The incidence of adverse effects was comparable between 2 groups. The anesthetic effectiveness was favorable in both groups. Patients in both groups were satisfactory with the fiberoptic bronchoscopy. Conclusion: In the intravenous anesthesia with dexmedetomidine and low dose propofol, oxygen supply via nasal catheter or new endoscopic nasal mask is safe and effective for fiberoptic bronchoscopy.
