Laryngeal Mask Airway Alternatives

We compared different ways of securing patients airways so that the patients can continue to be ventilated during planned opening of the trachea this procedure is needed for adults hospitalized for a length of time in an intensive care unit icu and continuing to require artificial ventilation the use of a laryngeal mask airway was compared with the existing endotracheal.

Laryngeal mask airway alternatives. Endotracheal intubation superior to laryngeal mask airway. There are some factors that preclude use of the lma discussed below. A laryngeal mask airway lma is a device inserted behind the mouth and nose connecting them to the food pipe pharynx to allow breathing oxygenation and administration of anesthetic gases without inserting a tube in the windpipe. They are effective alternatives to endotracheal intubation as well as bag mask ventilation.

Some of these devices called supraglottic airways sit right on top of the vocal cord structures. In the first paper on the lma 1 brain described the device as an alternative to either the endotracheal tube ett or the face mask with either spontaneous or positive pressure ventilation ppv. Laryngeal mask airway lma and supraglottic gel device i gel are considered alternatives to endotracheal tube. It was introduced into clinical practice in 1988.

This study sought to assess the success rate of airway management using lma and i gel in elective orthopedic surgery. The laryngeal mask airway lma is an alternative to the et tube that can sometimes be used. Et intubation is preferable to lma placement regardless of the patient s suspected covid 19 status because it allows the provider to. Complications include aspiration of stomach contents local irritation upper airway injuries mild sympathetic response obstruction laryngospasm pulmonary.

The lma laryngeal mask airway is an advanced airway alternative to endotracheal tube et intubation that provides comparable ventilation. We designed a prospective randomized multicenter study to compare anesthetic requirements recovery times and postoperative side effects when a laryngeal mask airway lma was used as an alternative to the tracheal tube tt during ambulatory anesthesia after induction of anesthesia with midazolam 2 mg fentanyl 1 micro g kg and propofol 2 mg kg 381 patients were randomly assigned to receive either an lma n 207 or tt n 174 for airway management. In recent years however alternative airway devices like laryngeal mask airway lma have been used in this patient group both in routine proce dures and in the presence of airway problems 1 endotracheal intubation is also suggested to open up the airway in laparos copic surgical procedures. An lma is a soft inflatable plastic or rubber device that is essentially an oxygen mask that goes inside the mouth to deep in the throat.

The main important method for airway management during anesthesia is endotracheal intubation.
