Interrupting gel layer between Double cuffs prevents fluid leakage past tracheal tube cuffs

Interrupting gel layer between Double cuffs prevents fluid leakage past tracheal tube cuffs.

BACKGROUND Current tracheal tubes (TTs) cannot guarantee a perfect seal against pulmonary aspiration of upper airway secretions. The purpose of this study was to investigate whether a gel layer between the tracheal tube with double cuffs (Double cuffs) prevents fluid leakage past TT cuffs. METHODS In vitro fluid leakage tests were performed using the Double cuff with or without a gel layer be...

Leakage of fluid around endotracheal tube cuffs: a cadaver study

BACKGROUND The aim of the study was to evaluate the leakage of liquid past the cuffs of tracheal tubes in fresh frozen human heads. METHODS Six truncated fresh frozen heads were used and intubated with 8.0 mm endotracheal tubes. The intracuff pressures tested were 30 and 100 cmH2O. Subsequently, 20 ml of each of two oral antiseptic rinses (0.2% chlorhexidine and octenidine [octenidol®, Schülk...

Endotracheal Tube Cuffs: Design and Function

RESPIRATION AND THE AIRWAY Effect of tracheal tube cuff shape on fluid leakage across the cuff: an in vitro study

Key points † Optimizing tracheal sealing is of clinical interest: fluid leakage past the tube cuff plays an important role in the pathogenesis of VAP. † Tapered shaped tube cuff offering a sealing zone with reduced folds and channels is a new strategy to minimize fluid leakage past the tracheal tube cuff. † Tracheal tube cuffs made from PVC show much more and faster fluid leakage than cuffs mad...

The effect of tracheal tube size on air leak around the cuffs

BACKGROUND This randomized single-blinded, cross-over study was done to evaluate the influence of the size of tracheal tubes on air leaks around the cuffs. METHODS In a benchtop model, the number of longitudinal folds on the cuffs was evaluated for different sizes of tracheal tubes. In an anesthetized patient study, thirty patients scheduled for elective surgery under general anesthesia were ...
