Application of threaded tube in atomisation inhalation for patients undergoing non-mechanical ventilation with...

To observe the effect of the combined use of threaded tubes and traditional atomisation devices on atomisation inhalation in patients.

This is a prospective study. A total of 105 comatose patients undergoing non-mechanical tracheal ventilation were included and divided into two groups: the experimental group (n = 56) and the control group (n = 49). The experimental group was provided with a combination of threaded tubes and traditional atomisation devices for inhalation, while the control group received only traditional atomisation devices. The study focused on comparing specific outcomes such as pulmonary infection rate and mucosal bleeding between the two groups.

There was no significant difference in sputum viscosity between the two groups on days 1-2 (P > 0.05). On days 3-5, there was a significant difference (P < 0.05) in sputum viscosity. Further comparison of the symptoms on days 1-5 showed the following: (1) the pulmonary infection rate in the experimental group was higher on day 1 (p = 0.044); (2) the respiratory patency of the experimental group was higher on day 2 (p = 0.007); (3) the experimental group had lower levels of airway mucosal bleeding and sputum scab formation and higher levels of respiratory patency on day 3 (p = 0.003, p = 0.001, p = 0.026); (4) the respiratory patency of the experimental group was higher on day 4 (p = 0.019); and (5) the incidence of sputum scab formation in the experimental group was lower and the respiratory patency was higher on day 5 (p = 0.002, p = 0.005).

The combined use of threaded tubes and traditional atomisation devices in patients undergoing non-mechanical ventilation with endotracheal intubation may offer potential benefits for airway management and respiratory health.
