Beskrivelse
Inclusion Criteria:
- Confirmed acute ischemic stroke by cranial CT or MRI.
- Age 18 years or older.
- Glasgow Coma Scale score of 6 to 12.

Exclusion Criteria:
- 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.
- Cervical spine fracture, atlantoaxial instability, or other condition restricting neck extension or movement.
- Confirmed or suspected pregnancy.
- 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.

Eksperimentel: 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.
|
|
Aktiv komparator: 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.
|
|
Aktiv komparator: 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.
