Hypothesis
Commercial devices would differ in the degree of total ETT movement occurring, and knots would differ in the degree of slippage occurring.
Conclusion
The Dale® device was the most secure among the tested devices, but no statistically significant differences were found between the knots.
Supporting Evidence
- The Dale® device showed less total movement than other devices tested.
- Differences in movement between the Dale and other devices were statistically significant for some comparisons.
- No significant differences in slippage were found among the knots tested.
Takeaway
This study looked at different ways to keep breathing tubes in place and found that one device worked best, but the knots used didn't show clear differences.
Methodology
The study used a PVC tube mannequin to test the movement of endotracheal tubes secured with various commercial devices and knots under dynamic loads.
Potential Biases
The study did not include all available devices and relied on samples provided by manufacturers, which may introduce bias.
Limitations
Sample sizes were small and determined by the number of devices provided by manufacturers, which may have affected the ability to detect significant differences.
