Reusable type can be re-sterilized maximum 40 times
Features:
Various sizes, from neonate to adult.
Re-usable up to 40 times.
Aperture bars designed to prevent the blockage of the airway by the epiglottis.
Soft, silicone cuff.
Facilitates smooth emergence from anaesthesia.
Minimal haemodynamic response.
Advantages:
Increased speed and ease of placement by inexperienced personnel;
Increased speed of placement by anaesthetists;
Improved haemodynamic stability at induction and during emergence;
Minimal increase in intraocular pressure following insertion;
Reduced anaesthetic requirements for airway tolerance;
Lower frequency of coughing during emergence;
Improved oxygen saturation during emergence;
Lower incidence of sore throat in adults.
The Reusable lma was introduced by Brain in 1988 with the goal of replacing the face mask during general anesthesia cases, thus avoiding more invasive methods of airway control.1 The Reusable lma forms an end-to-end seal with the larynx, as opposed to the endotracheal tube, which forms a sleeve-like junction with the trachea.
1 It is intended to be placed into the "pocket-like" hypopharynx, with its distal end wedged against the upper esophageal sphincter.
2 Several issues had to be overcome before the device was ready for use. These modifications, including design features that were intended to prevent epiglottic down-folding, reduce the likelihood of trauma and avoid gastrointestinal (e.g., retching and vomiting) and respiratory (e.g., coughing and bucking) rejection-type reflexes.
