Oropharyngeal Flushing Suction Tube With Laryngoscope for Stroke-Associated Pneumonia

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.
