전신마취 후 점액으로 인한 기관내관 폐쇄 : 증례보고 A case report = Endotracheal Tube Obstruction due to Mucous Crust after General Anesthesia

다국어 초록 (Multilingual Abstract)

Nasotracheal intubation is commonly and safely used in the anesthetic management of patients undergoing oral cavity surgery. But endotracheal tube obstruction causes serious complications, including pneumothorax, pulmonary edema, brain injury and death. We experienced a case of endotracheal tube obstruction due to mucous crust after general anesthesia. A 5-year-old woman with cleft palate was intubated with a 4.5 mm amored tube for general anesthesia. During the surgery, vital signs were within normal limits. In the intensive care unit, she exhibited sign of complete airway obstruction. We exchanged the tube with another tube after failure of suction. The airway obstruction was due to a dried mucous crust attached to the bevel of the endotracheal tube. We should keep in mind the presence of an amored endotracheal tube cannot be regarded as a guarantee of a patent airway.
