Acute pulmonary edema caused by impaired switching from nasal to oral breathing during the caldwell-luc operation resulting from anesthesia: a case report

Abstract

Nasotracheal intubation is performed routinely in maxillofacial surgery to optimize visualization of the surgical field. The CaldwellLuc operation is an approach to the maxillary sinus through the labiogingival sulcus and canine fossa. The operation is used to treat chronic maxillary sinusitis, and involves curettage of the mucosa of the maxillary sinus and the creation of an inferior meatal antrostomy. After the operation, a nasal Foley catheter is inserted into the inferior nasal meatus for the discharge of blood and tissue fluid. Then, the nostril is packed with vaseline gauze. Before the patients awaken, they experience impaired switching from nasal to oral breathing. Pulmonary edema can result from excessive negative intrathoracic pressure caused by acute airway obstruction in patients breathing spontaneously. During anesthesia and sedation, airway obstruction can occur at the levels of the pharynx and larynx. Even in patients who are awake, alteration in the ability to change the breathing route from nasal to oral may affect breathing in the presence of an airway obstruction, causing this catastrophic event. We experienced a case in which acute pulmonary edema resulted from acute airway obstruction triggered by the patient's inability to switch the breathing route from nasal to oral during emergence from anesthesia.
