Respiratory failure & ventilation
Detection of tongue edema caused by endotracheal intubation tube in intensive care unit (ICU) patients by ultrasonography: a prospective, observational, clinical study
Authors' conclusion
Tongue edema may develop due to the long-term application of pressure of the ETI tube on the tongue and may impair oxygenation after extubation.
Study context
- Population
- ICU patients aged 18–65 years on mechanical ventilation from day 0 of intubation
- Participants
- 100 patients
- Exposure
- Mechanical ventilation ≥4 days vs ≤3 days after endotracheal intubation (ETI)
- Studyn = 57
- Controln = 43reference
- Outcome
- Tongue edema (TSA2 − TSA1, tongue cross-sectional area by submental ultrasonography (USG))
Main finding
As reported in the abstract
Tongue edema
- Tongue edema more prevalent in the study group
- p < 0.01
Observational data: associations, not effects.
Further findings
SpO2 2 h after extubation vs tongue edema (control group)
- Significant negative correlation between SpO2 and increase in mean TSA
- P < 0.01
- SpO2 lower in patients with vs without tongue edema
- 4%
