Laryngeal mask airway LMA insertion is facilitated by sedation. Propofol Diprivan or midazolam Versed are acceptable choices. For elective ventilation in the operating room, less anesthesia is typically required for insertion and maintenance of the LMA than for endotracheal intubation. In the emergency setting, the patient is often obtunded or unconscious, and further sedation may
Laryngeal mask airways, or LMAs, have been in use since 1988. Since it can be very difficult to intubate some patients, especially in an emergency situation, this device was developed as an alternative to endotracheal intubation, but without the level of risk associated with intubation. LMAs cause less gastric distention and are less likely to
A laryngeal mask airway LMA — also known as laryngeal mask — is a medical device that keeps a patient's airway open during anaesthesia or unconsciousness. It is a type of supraglottic airway device. A laryngeal mask is composed of an airway tube that connects to an elliptical mask with a cuff which is inserted through the patient's mouth, down the windpipe, and once deployed forms an

Laryngeal mask airway LMA , which consists of a silicone tube connected to a miniature silicone mask appropriate for the shape of hypopharynx and covers the larynx as a gasket, was developed in 1980s in the United Kingdom. Although blind placement of LMA without using a laryngoscope is an advantage, it may turn into a disadvantage in
