Despite intermittent control of tracheal cuff pressure using a manual manometer, cuff underinflations and overinflations frequently occur in critically ill patients, resulting in increased risk for microaspiration and tracheal ischemic lesions. The aim of this study is to determine the efficiency of Mallinckrodt electronic device (Mallinckrodt electronic cuff pressure controller, VBM Medizintechnik GmbH, Sulz aN) in continuous control of tracheal cuff pressure.

continuous control of tracheal cuff pressure using an electronic device for 24 h followed by manual control of cuff pressure using a manometer
24 h of manual control using a manometer followed by 24 h of continuous control using an electronic device
ICU, Salengro Hospital, University Hospital of Lille
Lille, Nord, France
percentage of recording time spent with cuff overinflation or underinflation
Continuous recording of cuff pressure will be performed during 2 24-h periods (with or without Mallinckrodt device)
Time frame: 48 hours
Impact of Mallinckrodt electronic device on microaspiration of gastric contents, documented by pepsin levels in tracheal aspirates
Pepsin will be quantitatively measured in tracheal aspirates of all patients during the 2 24-h periods (with or without Mallinckrodt device)
Time frame: 48 hours
