Area of Science:

  • Anesthesiology
  • Airway Management

Background:

  • The laryngeal mask is an airway device placed in the hypopharynx.
  • It separates the digestive tract from the airway without impacting the larynx or upper esophageal sphincter.

Purpose of the Study:

  • To review the applications and limitations of the laryngeal mask in clinical practice.
  • To highlight its advantages in various anesthetic scenarios.

Main Methods:

  • Review of laryngeal mask usage in anesthesia and intensive care.
  • Discussion of indications, contraindications, and complications.

Main Results:

  • The laryngeal mask provides a patent airway with good patient tolerance, even under light sedation.
  • Advantages include ease of insertion, no vocal cord contact, and freeing anesthesiologist's hands.

  • Contraindicated in cases of potential regurgitation; not a substitute for endotracheal intubation but useful in emergencies or while awaiting intubation expertise.

    • Conclusions:

    • The laryngeal mask is a valuable tool for airway management in operating rooms and emergencies.
    • Its use is limited in intensive care due to pulmonary pathology and potential for regurgitation.
