Hypothesis
Efficient continuous control of the endotracheal cuff pressure using a pneumatic device would reduce tracheal ischemic lesions in piglets ventilated for 48 hours.
Conclusion
The pneumatic device provided effective continuous control of endotracheal cuff pressure, but did not significantly reduce tracheal mucosal lesions.
Supporting Evidence
- The cuff pressure was significantly lower in piglets with the pneumatic device than in those without.
- No significant difference was found in the percentage of time spent with a cuff pressure <15 cmH2O.
- Histological examination showed no difference in tracheal lesions between animals with and without the pneumatic device.
Takeaway
Using a special device to keep the air pressure in breathing tubes steady helps control the pressure, but it doesn't stop damage to the trachea in piglets after two days.
Methodology
Twelve piglets were intubated and ventilated for 48 hours, randomized to either manual or continuous cuff pressure control.
Potential Biases
Potential bias due to the small number of animals and short duration of mechanical ventilation.
Limitations
The study duration was only 48 hours, and the sample size was small.
Participant Demographics
Healthy, bred, domestic Largewhite-Landrace piglets, weighing 22 ± 2 kg.
