A Case of Pulmonary Edema following Extubation of Laryngeal Mask Airway (LMA)

Abstract

We experienced a case of pulmonary edema due to upper airway obstruction which was caused by the stimulation associated with LMA extubation. After confirming that the patient could respond to verbal commands at the end of orthopedic surgery under general anesthesia LMA was extubated. The patient developed laryngospasm and ventilation with a face mask was unsuccessful. The patient was intubated immediately with a endotracheal tube with the aid of muscle relaxant. Pink froth was suctioned though endotracheal tube. The diagnosis of pulmonary edema was ascertained with chest X-P. The patient stayed in the ICU for one night. Careful history-taking in the ward later revealed that he had had an irritated throat for two to three days prior to the surgery. We have to be careful in the selection of the patient when we utilize LMA.
