What Researchers Did
Researchers reviewed how endotracheal tube cuff management for intubated children transported by air has changed over time.
What They Found
Problems with extremely high endotracheal tube cuff pressures in adults due to altitude gain were identified by the 1970s, leading to research and device development. However, children were largely excluded from these studies as they were transported less often and typically used non-cuffed tubes. While hyperbaric medicine adopted incompressible liquids for cuff inflation, aeromedical transport has not consistently used this method.
What This Means for Canadian Patients
For Canadian children requiring air ambulance transport while intubated, proper management of endotracheal tube cuff pressure is vital. Changes in altitude during flight can alter cuff pressure, potentially causing harm if not correctly managed. Adopting best practices for cuff management can improve safety for these vulnerable patients.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
This historical review highlights a lack of patient outcome trials specifically for children regarding endotracheal tube cuff management during aeromedical transport.
