Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

388
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...

Area of Science:

  • Otolaryngology
  • Medical Imaging
  • Artificial Intelligence

Background:

  • Laryngeal neoplasms require accurate diagnosis for effective treatment.
  • Distinguishing between benign, precancerous, and cancerous laryngeal lesions can be challenging via visual assessment during laryngoscopy.

Purpose of the Study:

  • To develop and evaluate a deep-learning-based computer-aided diagnosis (CADx) system for laryngeal neoplasms.
  • To enhance the accuracy of diagnostic assessments of laryngoscopy findings.

Main Methods:

  • A retrospective study utilizing a dataset of 24,667 laryngoscopy images.
  • Development and testing of a convolutional neural network (CNN) classifier.
  • Comparison of CNN performance against clinical visual assessments (CVAs) by 12 otolaryngologists.

Main Results:

  • The CNN achieved an overall accuracy of 96.24% on an independent test dataset.
  • High sensitivity and specificity were reported for various laryngeal conditions, including leukoplakia, benign lesions, malignancy, normal findings, and vocal nodules.
  • The CNN-based classifier demonstrated superior performance compared to otolaryngologists in distinguishing nodules, polyps, leukoplakia, and malignancy.

Conclusions:

  • A CNN-based classifier offers a valuable tool for diagnosing laryngeal neoplasms during laryngoscopy.
  • The system shows particular promise in differentiating benign, precancerous, and cancerous laryngeal lesions.
