While intubated, the endotracheal tube puts pressure on surrounding tissue and may cause mucosal edema which can lead to post-extubation laryngeal edema (PLE). PLE can cause failure of extubation, and occurs in 5.0-54.4% of patients after extubation. In a majority of studies, failed extubation is defined as re-intubation within 48 hours after extubation. A relationship between re-intubation and increased mortality has been shown. To identify patients at risk of failure before extubation, Potgieter described the cuff leak test in 1988, and Miller et al revised the method to be quantitative in 1996. Although many studies have been done on the cuff leak test, there are some critical limitations including insufficient diagnostic accuracy. This column introduces the history of the cuff leak test, clinical studies, and guidelines and precautions for its use.
