Summary

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.

Conditions

  • Acute Ischemic Stroke
  • Stroke-Associated Pneumonia (SAP)

Interventions

DEVICE

Oropharyngeal Flushing Suction Tube

A patented single-use dual-lumen suction tube designed for simultaneous irrigation and suction of oropharyngeal and deep pharyngeal secretions under direct laryngoscopic visualization. The device includes separate irrigation and suction lumens and allows sterile saline irrigation with simultaneous suction when secretions are tenacious.

PROCEDURE

Laryngoscope-Guided Oropharyngeal Suction

Direct laryngoscopy is used to visualize the oropharyngeal and glottic area and guide targeted suctioning of oropharyngeal and deep pharyngeal secretions.

DEVICE

Standard Suction Catheter

A conventional single-lumen suction catheter used for oropharyngeal or airway secretion suctioning according to routine clinical practice.

PROCEDURE

Conventional Oral or Nasal Suction

Blind oral and/or nasal suctioning performed with a standard suction catheter according to routine clinical practice, without direct laryngoscopic visualization and without use of the oropharyngeal flushing suction tube.
