Clinical Study on the Efficacy of Subglottic Suction in Mechanically Ventilated Patients Guided by Bedside Ultrasound

Subglottic suctioning, as an important airway management technique, has its operational accuracy and safety directly impacting patient prognosis. Therefore, improving the effectiveness and safety of subglottic suctioning has become a focus of clinical attention. Point-of-care ultrasound, which can provide imaging, can be used to guide subglottic suctioning, enhancing the intuitiveness of the procedure. This study aims to evaluate the safety and effectiveness of subglottic suctioning guided by point-of-care ultrasound in mechanically ventilated patients, in order to help standardize clinical practice and improve medical quality.
