Oropharyngeal Flushing Suction Tube With Laryngoscope for Stroke-Associated Pneumonia (OFST-SAP)
2026年6月17日 更新者：Qiancheng Luo, MD、Shanghai Pudong New Area Gongli Hospital
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.

詳細な説明
This is an investigator-initiated, single-center, prospective, three-arm, parallel-group, randomized controlled trial.
A total of 120 adult patients with acute ischemic stroke, Glasgow Coma Scale scores of 6 to 12, and no artificial airway or invasive mechanical ventilation at enrollment will be randomized in a 1:1:1 ratio to one of three groups: oropharyngeal flushing suction tube plus laryngoscope, standard suction tube plus laryngoscope, or conventional oral/nasal suction.
All groups will receive standard stroke care and routine oral care.
The primary outcome is the incidence of stroke-associated pneumonia within 28 days after enrollment.
Secondary outcomes include 28-day all-cause mortality, establishment of artificial airway or invasive mechanical ventilation, longitudinal inflammatory biomarkers, pathogen distribution and multidrug-resistant organism detection, and procedure-related adverse events.

実験的：Oropharyngeal Flushing Suction Tube Plus Laryngoscope
Participants receive standard stroke care and routine oral care plus direct laryngoscope-guided suction using the oropharyngeal flushing suction tube.
Sterile saline irrigation of approximately 5 mL may be delivered through the irrigation lumen with simultaneous suction when secretions are tenacious.
|
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.
Direct laryngoscopy is used to visualize the oropharyngeal and glottic area and guide targeted suctioning of oropharyngeal and deep pharyngeal secretions.

|
アクティブコンパレータ：Standard Suction Tube Plus Laryngoscope
Participants receive standard stroke care and routine oral care plus direct laryngoscope-guided suction using a standard single-lumen suction catheter.
No oropharyngeal flushing suction tube is used.
|
Direct laryngoscopy is used to visualize the oropharyngeal and glottic area and guide targeted suctioning of oropharyngeal and deep pharyngeal secretions.
A conventional single-lumen suction catheter used for oropharyngeal or airway secretion suctioning according to routine clinical practice.
|
|
アクティブコンパレータ：Conventional Oral or Nasal Suction
Participants receive standard stroke care and routine oral care plus conventional blind oral and/or nasal suction using a standard suction catheter.
No laryngoscope and no flushing suction tube are used.
|
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.
