Randomized Controlled Trial
Evaluation of a Closed Suction System with Integrated Tube Scraping Technology: A Randomized Controlled Trial.
Endotracheal tube (ETT) scraping or sweeping refers to mucus removal from an ETT that can increase airway resistance. The study objective was to evaluate the effect of ETT scraping on the duration of mechanical ventilation, time to first successful spontaneous breathing trial (SBT), duration of hospital stay, and occurrence of ventilator-associated events (VAEs). ⋯ ETT suctioning plus scraping, compared to ETT suctioning alone, did not significantly improve the duration of mechanical ventilation, time to first successful SBT, length of hospital stay, and VAEs. These study findings do not support the routine use of ETT scraping for mechanically ventilated patients.
