AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for adults with a confirmed acute ischemic stroke and reduced consciousness, who are not on a breathing tube or ventilator. It tests a throat flushing and suction tube used with a laryngoscope.

- Original description
Stroke-associated pneumonia is a common and clinically important complication after acute ischemic stroke, especially in non-intubated patients with impaired consciousness and reduced cough or swallowing reflexes. Conventional oral or nasal suction may be insufficient for removing deep oropharyngeal secretions. This prospective randomized controlled trial will evaluate whether a patented oropharyngeal flushing suction tube combined with direct laryngoscopy reduces the 28-day incidence of stroke-associated pneumonia compared with laryngoscope-guided standard suction and conventional oral/nasal suction.Read full original descriptionShow less
Translational Application of an Oropharyngeal Flushing Suction Tube Combined With Laryngoscope for Improving Prognosis in Stroke-Associated Pneumonia: A Prospective Randomized Controlled Trial
Stroke-associated pneumonia is a common and clinically important complication after acute ischemic stroke, especially in non-intubated patients with impaired consciousness and reduced cough or swallowing reflexes. Conventional oral or nasal suction may be insufficient for removing deep oropharyngeal secretions. This prospective randomized controlled trial will evaluate whether a patented oropharyngeal flushing suction tube combined with direct laryngoscopy reduces the 28-day incidence of stroke-associated pneumonia compared with laryngoscope-guided standard suction and conventional oral/nasal suction.
Inclusion: Confirmed acute ischemic stroke by cranial CT or MRI; Age 18 years or older; Glasgow Coma Scale score of 6 to 12; No artificial airway and no requirement for invasive mechanical ventilation at enrollment; Written informed consent provided by the participant or legally authorized representative.
Exclusion: Pre-existing pulmonary infection at enrollment, or definite extra-pulmonary organ or tissue infection during the study period; Hemorrhagic blood disorder, clinically significant coagulopathy, or bleeding risk precluding laryngoscopy; Cervical spine fracture, atlantoaxial instability, or other condition restricting neck extension or movement; Irreversible critical illness with anticipated survival less than 28 days; Uncontrolled hypertension or recurrent malignant arrhythmias; Other conditions judged by investigators to make participation unsuitable; Existing artificial airway or invasive mechanical ventilation at ICU admission or screening; Oral or maxillofacial deformity impeding laryngoscope insertion; Confirmed or suspected pregnancy.
