About this 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.
Eligibility criteria
Qualifiers
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.
Disqualifiers
Existing artificial airway or invasive mechanical ventilation at ICU admission or screening.
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.
Oral or maxillofacial deformity impeding laryngoscope insertion.
