The safety of reused endotracheal tubes sterilized according to Centers for Disease Control and Prevention guidelines.
STUDY OBJECTIVE To investigate safety issues associated with the reuse of sterilized endotracheal tubes (ETTs). DESIGN Prospective, randomized study. SETTING Laboratory in vivo testing. INTERVENTION Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa were inoculated onto ETT cuffs. Following inoculation, ETTs were sterilized with either ethylene oxide or glutaraldehyde. Cu...
متن کاملIntracuff pressures in endotracheal and tracheostomy tubes. Related cuff physical characteristics.
This study compared intracuff pressure (ICP) during mechanical ventilation in a variety of currently used endotracheal (ET) and tracheostomy (trach) tube cuffs and related cuff physical characteristics. Tracheostomy tube physical characteristics were also measured. Variation was observed to exist between "just-seal" inspiratory and end-expiratory intracuff pressure during mechanical ventilation...
متن کاملComparison 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...
متن کاملAssessment of aspiration risk from dynamic modulation of endotracheal tube cuff pressure.
OBJECTIVES/HYPOTHESIS To assess the risk of aspiration using a novel valve circuit that dynamically modulates endotracheal tube cuff pressure during the ventilatory cycle using bench and live animal models. STUDY DESIGN Animal model. METHODS The bench model consisted of a cuffed endotracheal tube inserted into an artificial trachea. Leakage of liquid around the cuff was measured after 4 hou...
متن کاملEndotracheal tubes for critically ill patients: an in vivo analysis of associated tracheal injury, mucociliary clearance, and sealing efficacy.
BACKGROUND Improvements in the design of the endotracheal tube (ETT) have been achieved in recent years. We evaluated tracheal injury associated with ETTs with novel high-volume low-pressure (HVLP) cuffs and subglottic secretions aspiration (SSA) and the effects on mucociliary clearance (MCC). METHODS Twenty-nine pigs were intubated with ETTs comprising cylindrical or tapered cuffs and made o...
