A laryngeal mask airway (LMA), also known as laryngeal mask, is a medical device that keeps a patient's airway open during anaesthesia or while they are unconscious. It is a type of supraglottic airway device.

Laryngeal mask airways come in several types, as follows: The LMA Classic is the original reusable design. The LMA Unique is a disposable version, making it ideal for emergency and prehospital...

The laryngeal mask airway (LMA) was invented in 1983 by Archie Brain, MD, as an alternative airway device to the facemask and endotracheal tube (ETT). 1 Since the establishment of the classical LMA, the device has undergone multiple improvements and modifications (Table 1).

2023年7月11日 · Laryngeal mask airways (LMA) are single-use or reusable supraglottic airway devices that may be used as a temporary method to maintain an open airway during the administration of anesthesia or as an immediate life-saving measure in a difficult or failed airway as outlined in the difficult airway algorithm published by many societies of anesthesi...

The intubating laryngeal mask airway (ILMA) was developed through the aid of analysis of magnetic resonance images of the human pharynx and laboratory testing of ET tubes. 4 The new and more “anatomically correct” ILMA effects more precise placement.

2021年2月11日 · In this single-blind randomized controlled trial, intraoperative arterial carbon dioxide partial pressure at 2 h after the airway devices insertion (P a CO 2_ 2h) was compared as a primary outcome. Participants were randomly assigned to the following groups: Group LMA (n = 45, used Protector LMA), or Group ETT (n = 43, used cuffed ETT).

2010年1月1日 · The LMA™ was invented by Dr. Archie Brain in 1981. 1 Commercial products were introduced in England in 1988 and approved for use in the United States in 1991. 2 Over the past 21 years, the LMA™ (Laryngeal Mask Airway) has been modified to offer more clinical options as well as to enhance patient safety.

Our primary aim was to evaluate i-Gel and laryngeal mask airway (LMA) classic as conduits for tracheal intubation using ventilating bougie by assessing number of attempts and time for insertion of SGAs, ventilating bougie and endotracheal tube (ETT), and total intubation time.

Supraglottic airway (e.g. laryngeal mask airway [LMA], i-Gel) What is a supraglottic airway? A flexible plastic tube with inflatable circular opening on end which sits over top of larynx Provides some aspiration protection but doesn’t fully secure the airway Can only withstand a small amount of positive pressure ventilation It is attached to ventilation […]
