Alfentanil and propofol induced anesthesia for patients with huge endotracheal tumor undergoing fiberoptic bronchoscopic interventional therapy: case report

Background: There is a high risk of hypoxia or apnea for patients with huge tracheal tumor during general anesthesia. Here we reported two cases of extremely huge endotracheal tumors undergoing fiberoptic bronchoscopic interventional therapy under general anesthesia. We hope the experience will be of reference value for formulating reasonable anesthesia scheme for such critically ill patients. Case Description: The two patients were accompanied with severe respiratory distress. And fiberoptic bronchoscopy revealed that the trachea cavity was blocked nearly completely by extremely huge tracheal tumor. Tracheal tumors were scheduled to be removed with fiberoptic bronchoscopic interventional therapy. General anesthesia was inducted with alfentanil and propofol. Then a laryngeal mask was inserted and spontaneous breath was preserved. During the operation, complete airway obstruction occurred, but it was effectively handled by using the fiberoptic bronchoscope to push the tumor and reopen the gap between the mass and the tracheal wall. After the therapy, the patients??? symptom of respiratory distress was relieved significantly. Conclusion: For patients with huge tracheal tumor that to be handled with fiberoptic bronchoscopic interventional therapy, general anesthesia with spontaneous breath induced by alfentanil and propofol is preferable. The most important, when complete airway blockade occurs during the process, pushing the tumor and reopening the respiratory tract with fiberoptic bronchoscope is a fairly effective solution to enable patients to be reoxygenated.
