Plain English Summary
Background and study aims
In the case of a dry airway, viscous sputum and tracheal intubation easily lead to an increased chance of pulmonary infection in patients. However, at present, the atomization device used to moisten the airway cannot be connected to the mouth end of tracheal intubation, which causes liquid waste during drug atomization inhalation, resulting in insufficient atomization. This study aims to observe the effect of the combined use of threaded tubes and traditional atomisation devices on atomisation inhalation in patients.
Who can participate?
Comatose patients undergoing non-mechanical tracheal ventilation
What does the study involve?
Through convenience sampling, this study enrolled patients undergoing non-mechanical ventilation with endotracheal intubation admitted to the Neurosurgery Department of the Second Hospital of Hebei Medical University between March 2020 and September 2023. The included patients were divided into two groups: the experimental group and the control group. The experimental group was provided with threaded tubes and traditional atomization devices for inhalation, while the control group received only traditional atomization devices.
What are the possible benefits and risks of participating?
Combining 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.
No risks provided at publication.

Approved 02/03/2020, Research Ethics Committee of the Second Hospital of Hebei Medical University (No.215 Heping West Road, Shijiazhuang City, 050000, China; +86 0311 66002811; ydeyjf@126.com), ref: 2020-R073 |
| Condition | Atomisation inhalation for patients undergoing non-mechanical ventilation with endotracheal intubation |
| Intervention | 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 atomization devices for inhalation, while the control group received only traditional atomization devices. In the control group, a traditional mask-type atomiser with liquid medicine was employed to align with the end of the endotracheal intubation tube for atomisation inhalation. The experimental group used a threaded tube combined with a traditional atomisation device. The atomizing fluids used included levosalbutamol hydrochloride nebulization solution 0.63g TID, N-acetylcysteine solution for inhalation 0.3g BID, and budesonide suspension for inhalation 2mg BID, with BID administration at 9:00 and 16:00, and TID at 9:00, 17:00, and 1:00. All tubes used had the same inner diameter of 7.5mm. To use the device, the cap at the suction port of the threaded tube was removed, followed by the mask removal. The liquid medicine was then placed into the mask-type atomisation inhalation device, which was connected to the rear end of the threaded tube, while the front end of the threaded tube was connected to the inlet end of the endotracheal intubation tube. Placement was assessed using end-tidal CO₂ monitoring. There was no difference in the time, frequency, and humidifying fluid used for atomisation between the two groups of patients. Both groups received routine nursing care for endotracheal intubation, and the same suctioning method was used for aspiration of sputum. The nebulizer used in both groups was produced by Ningbo Shengrui Medical Appliance Co., Ltd. |

| Primary outcome measure | The following primary outcome measures were assessed at time points on days 1-5 after humidification: 1. Sputum viscosity is evaluated by clinical doctors based on standardized grading scales 30 minutes after each nebulization session, with assessments carried out twice daily 2. Sputum pH value measured using pH test paper and comparison with the acid-base colorimetric card 30 minutes after each nebulization session, with assessments carried out twice daily |
| Secondary outcome measures | The following secondary outcome measures were assessed at time points on days 1-5 after humidification: 1. Airway mucosal bleeding measured by observation of airway mucosal bleeding was conducted 30 minutes after each nebulization session, with assessments carried out twice daily 2. Sputum scab formation measured using data recording observations of resistance during the insertion of the conventional suction catheter, small sputum scabs inside the suction catheter during suctioning and/or sputum scabs on the suction catheter during suctioning 4 hours after each nebulization session, with assessments carried out twice daily 3. Respiratory patency measured using a combination of physical examination, including observation and auscultation, the analysis of capnography and ventilator settings to ensure a comprehensive evaluation of airway obstruction and ease of breathing 4 hours after each nebulization session, with evaluations carried out twice daily 4. Pulmonary infection measured by conducting bedside lung ultrasound assessments at a fixed time each day, specifically at 18:00, to provide more continuous and dynamic monitoring of the patient’s pulmonary infection status |
