Pressure changes in 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...

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 ...

Endotracheal Tube Cuffs: Design and Function

Comparison of tracheal tube cuff inflation pressure among anesthesia team with different gradual level

Background & Objectives: Tracheal intubation is frequently performed in operating room. Over inflation of the endotracheal tube cuff is a risk factor for tracheal ischemia and subsequent complications. On the other hand inadequate cuff pressure increases the risk of aspiration of gastric contents. In this study, the endotracheal tube cuff pressure filled by the anesthesia team has been compared...

Maintenance of tracheal tube cuff pressure: where are the limits?

Continuous control of tracheal tube cuff inflation using a pneumatic device resulted in severe tracheal wall damage in ventilated piglets. This damage was similar in piglets managed with manual control of cuff inflation. The periodic hyperinflation of the tube cuff used in both groups of this study may explain these results. This manoeuvre should be avoided in clinical practice.
