what does lma mean
Within 3 years of launch in the UK, the device had been used in at least 2 million patients and was available in every hospital. San Diego, Calif: LMA North America Inc. Brimacombe R, Brain AIJ, Berry A (1997). [Medline], This page was last edited on 15 October 2020, at 09:51. Br. Silicone prototypes looked promising as what was produced was an ellipse with a flat central web which, if cut correctly, could be used to create an aperture bar to prevent the epiglottis falling into the distal aperture. A laryngeal mask has an airway tube that connects to an elliptical mask with a cuff. Brain realised the exciting possibility that the laryngeal mask could be applied to head and neck surgery[3] and also observed that "In two patients the anatomy was such as to suggest that endotracheal intubation might have presented at least moderate difficulty. The laryngeal mask was invented by British anaesthesiologist/anaesthetist Archibald Brain in the early 1980s and in December 1987 the first commercial laryngeal mask was made available in the United Kingdom. Annual Report 2011, pp. The laryngeal mask airway. Brodrick P.M., Webster N.R., Nunn J.F. Get the top LMA abbreviation related to Text Messaging. Brain AIJ, Denman WT, Goudsouzian NG (1999). [4] By 1985, experience with the laryngeal mask prototype had reached 4000 cases. Thirdly, it was possible to maintain a clear airway throughout transfer of the patient to the recovery room." A study of 100 patients during spontaneous breathing. The anaesthesia community had been calling for practice guidelines and in 1992 the ASA commissioned a task force to establish practice guidelines for managing difficult airway situations. [6], On 5 December 1987, Brain received the first case of all-factory-made, silicone cuffed, LMA Classic laryngeal mask distributed by The Laryngeal Mask Company Limited. 10, Joseph R. Brimacombe, Laryngeal Mask Airway: Principles and Practice, Second Edition (2005), pp. What does LMA stand for in Text Messaging? LMA is listed in the World's largest and most authoritative dictionary database of abbreviations and acronyms The Free Dictionary LMA International N.V. Philadelphia, Pa: Saunders; pp. Existing airway devices clearly failed to form this junction; the face-mask sealed against the face, and the endotracheal tube penetrated too far so that the junction was created within the trachea, instead of at its beginning. What does LMA stand for in text In sum, LMA is an acronym or abbreviation word that is defined in simple language. J. Anaeth, 55(8), 803, Joseph R. Brimacombe, Laryngeal Mask Airway: Principles and Practice, Second Edition (2005), pp. The cuff can either be of the inflating type (achieved after insertion using a syringe of air), or self-sealing. The LMA Classic was launched in the UK and the British anaesthesia community were quick to realise the potential benefits of the laryngeal mask. Rothrock J. Alexander's - Care of the Patient. Brain published a case series in Anaesthesia in 1985 describing the management of 3 difficult airway patients, illustrating the use of the laryngeal mask for airway rescue. The laryngeal mask revolutionised anaesthetic practice and by 1995 had been used in excess of 100 million patients and was available in more than 80 countries throughout the world. 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. Firstly, excellent airway patency was obtained in 98% of patients and did not deteriorate during the course of the anaesthetic. By December 1986, Brain was ready to conduct the first wholly independent trial and chose John Nunn to be the recipient of the silicone prototypes to conduct the trial. Brain concluded that current techniques for connecting artificial airways to the patient were not ideal, reasoning that if the respiratory tree is seen as a tube ending at the glottis and the objective is to connect this tube to an artificial airway, the most logical solution was to create a direct end-to-end junction. However the limitation of the prototypes remained, a new material was urgently needed. [5] "There were three outstanding advantages of the LMA in patients who breathed spontaneously. Emergence from anaesthesia was also noted to be uneventful and only 3 patients complained of a sore throat, a marked contrast to endotracheal tube anaesthesia. Finally, Dr Brain used the device in a dental extraction patient, he realised that because the space in and around the glottis was filled by the mask, the need for packing was much reduced and more impressively the larynx was completely protected from surgical debris. 15, Joseph R. Brimacombe, Laryngeal Mask Airway: Principles and Practice, Second Edition (2005), pp. 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. The laryngeal mask had now been widely accepted as a form of airway management.[7]. 2000; 102 (suppl 1): I95–I104. By 1992, the laryngeal mask was approved for sale and being sold in Australia, New Zealand, South Korea, Hong Kong, Taiwan, Malaysia, India and the United States. [citation needed], Following the realisation that a new material was needed, Brain looked at a number of options; polyvinyl chloride was too rigid and synthetic foam did not lend itself to re-use. Missouri; Saunders; 2003; 236. All content on this website, including dictionary, thesaurus, literature, geography, and other reference data is for informational purposes only. Following the success of the initial study, Brain successfully inserted and ventilated 6 anaesthetised, non-paralysed patients. The silicone prototype was also smooth and deflated into a wafer thin ellipse, however, the silicone mask was unable to retain the desired bowl shape and it was no longer possible to make rapid adjustments to the design. 23–26, "The laryngeal mask airway: its features, effects and role" [abstract]", "The laryngeal mask airway: a new concept in airway management", http://medind.nic.in/iad/t05/i4/iadt05i4p308.pdf, Intraoperative neurophysiological monitoring, ASA physical status classification system, Helsinki Declaration for Patient Safety in Anaesthesiology, American Association of Nurse Anesthetists, American Society of Anesthesia Technologists & Technicians, Association of Anaesthetists of Great Britain and Ireland, Australian and New Zealand College of Anaesthetists, International Anesthesia Research Society, https://en.wikipedia.org/w/index.php?title=Laryngeal_mask_airway&oldid=983630944, Articles with unsourced statements from July 2017, Creative Commons Attribution-ShareAlike License.
