Validation of a new method for safely suctioning sputum in comatose patients

Verification of the Effect of Intermittent Negative Pressure Sputum Suction Through Oral Pharyngeal Ventilation Tube in Comatose Patients

Not applicable Interventional Affiliated Hospital of Nantong University · NCT06508008

This study is testing two different ways to safely clear mucus from the airways of comatose patients to see which method is better for their comfort and safety.

What this trial studies

This study involves 600 comatose patients in a hospital in China, who are randomly assigned to two groups to compare different sputum suction methods. Group A will use intermittent negative pressure suction through oral and pharyngeal ventilation, while Group B will use continuous negative pressure suction through standard oral and nasal suction. The research aims to evaluate the effectiveness, safety, and patient comfort associated with these suction techniques, as well as to determine the best practices for oropharyngeal ventilation tube placement. Key indicators such as blood oxygen saturation and respiratory distress will be monitored to assess the outcomes of the interventions.

Who should consider this trial

Good fit: Ideal candidates for this study are comatose patients diagnosed with stroke.

Not a fit: Patients with multiple organ failure or multiple organ bleeding are unlikely to benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the safety and effectiveness of sputum suction in critically ill patients, enhancing their overall respiratory care.

How similar studies have performed: While similar studies have explored sputum suction techniques, this specific approach and validation are novel and have not been extensively tested.
