Effect of a Novel Tracheostomy Tube Fixation Device on Nursing Efficiency, Complication Rates, and Patient Comfort in Post-Tracheostomy Patients: A Randomized Controlled Trial

Tracheostomy is commonly performed in patients who require airway management after oral and maxillofacial head and neck tumor surgery. Stable fixation of the tracheostomy tube and appropriate wound care are important for maintaining airway safety, reducing local complications, and improving patient comfort. Conventional fixation methods, such as gauze ties or routine fixation straps, may become contaminated by blood or secretions, may cause friction or pressure on the cervical skin, and may require frequent replacement. These issues can increase nursing workload and may contribute to local skin injury, infection, tube displacement, or patient discomfort.

This randomized controlled trial was designed to evaluate the clinical application value and efficacy of a novel self-adhesive bidirectional tracheostomy tube fixation device. The device is intended to provide stable tracheostomy tube fixation while facilitating wound observation, dressing replacement, and daily nursing care.

Eligible patients were post-tracheostomy patients with oral cancer who were conscious, had adequate comprehension and communication ability, had intact cervical skin without infection or skin disease, and provided informed consent. Patients with pre-existing pressure injury, skin damage, allergy, or infection in the anterior cervical region before tracheostomy, pregnant women, minors, and patients with psychiatric disorders were excluded.

Participants were randomly assigned to two groups. The control group received routine tracheostomy care, including conventional tube fixation, nebulization therapy as prescribed, sputum suctioning as needed, regular inner cannula cleaning, and routine sterile gauze dressing care. The treatment group received routine tracheostomy care plus the novel self-adhesive bidirectional tracheostomy tube fixation device. The device was replaced once daily, or earlier if blood or exudate soaked two-thirds of the device.

The primary outcome was the occurrence of infection or inflammatory signs around the tracheostomy wound, including redness, swelling, heat, and pain. Secondary outcomes included the frequency of device or dressing replacement, duration of each wound care procedure, new cervical skin injury, tracheostomy tube displacement, and patient-reported neck comfort. Safety assessments included changes in oxygen saturation before and after use and the recording of adverse events, including tube dislodgement.
