Stroke
Conditions
Brief summary
This study aims to compare the efficacy and safety of the Speaking Valve trial versus the traditional Capping trial as indicators for tracheostomy decannulation in stroke patients. The trial is a prospective, multicenter, randomized, parallel-group, outcomes-assessor-blinded study with an exploratory crossover design.
Detailed description
Stroke survivors may develop disorders of consciousness, dysphagia, and airway dysfunction, with some requiring tracheostomy for prolonged mechanical ventilation or airway protection. Prolonged tracheostomy tube placement can lead to complications such as infection, tracheal stenosis, and communication difficulties. Timely and safe decannulation is crucial for rehabilitation. While the capping trial (typically 48-72 hours) is widely used, the speaking valve offers potential advantages by restoring physiological airflow and facilitating communication. This trial will systematically compare these two methods to provide evidence for optimizing decannulation protocols.
Interventions
Stepwise tolerance assessment: 0.5 hour → 4 hours. Decannulation Criteria: Continuous tolerance for 4 hours with stable vital signs, peripheral capillary oxygen saturation(SpO₂) ≥93% (on room air or low-flow oxygen), no significant respiratory distress. If patients in the Capping Group group cannot tolerate continuous catheter occlusion for 48 hours, they are transferred to the Speaking Valve group and undergo a 4-hour voice valve test starting at 0.5 hours.
Gradual capping: 1hour → 48hours. Decannulation Criteria: Continuous tolerance for 48 hours with stable vital signs, SpO₂ ≥93% (on room air or low-flow oxygen), no significant respiratory distress.
