Modified Cuff Leak Test for Predicting the Risk of Reintubation in Patients with Invasive Mechanical Ventilation: A Multicenter, Single-Blind, Randomized Controlled Trial.

Background: The cuff leak test (CLT) is an important tool to assess the risk of upper airway obstruction after extubation.

Research Question: Does modified CLT approach have superior ability in predicting re-intubation compared with traditional method?

Study Design And Methods: This was a prospective, multicenter, randomized control trial. The primary end point was the incidence of the need for reintubation within 48 h after extubation.
