Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

879
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway...

Suctioning the Nasopharyngeal Airway

6.0K
Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

Area of Science:

  • Otolaryngology
  • Laryngology
  • Surgical Innovation

Background:

  • Glottic insufficiency, often caused by vocal fold paralysis, leads to dysphonia and aspiration.
  • Traditional treatments for glottic insufficiency can be invasive.

Purpose of the Study:

  • To evaluate the efficacy and safety of transnasal fiber-optic injection laryngoplasty for treating glottic insufficiency.

Main Methods:

  • Review of video recordings from patients undergoing fiber-optic injection laryngoplasty.
  • Assessment using GRBAS scale, laryngeal videostroboscopy, and frame-by-frame analysis of glottic closure.

Main Results:

  • The procedure was well-tolerated, with significant improvements in phonatory symptoms (66.66%) and aspiration (50%).
  • Significant reduction in perceptual dysphonia scores and complete glottic closure in 66.66% of patients.
  • Mean closed quotient increased significantly from 0.10 to 0.51.

Conclusions:

  • Transnasal fiber-optic injection laryngoplasty is a safe and well-tolerated procedure.
  • The technique yields good outcomes for patients with glottic insufficiency.
