Unfortunately, many standards of care are never tested, but instead are often promoted based on pathophysiological explanations or simply being long-established practices. Much of medical practice is based on dogma: a set of principles laid down by authority as incontrovertibly true. This article evaluates four commonly taught dogmatic practices in emergency medicine to determine if they are supported by the medical literature or are instead myths and misconceptions: (1) topical anaesthetics inhibit corneal healing, (2) treatment of myocardial infarction is MONA (morphine, oxygen, nitrates, aspirin), (3) children do not get sprains because their ligaments are stronger than bone, and (4) vagal manoeuvres for supraventricular tachycardia never work in adults. Medicine is changing all the time, and the best way to ensure that one is practicing medicine that is accurate, up to date and not prone to being reversed is to always be sceptical and to learn how to read and interpret the medical literature.<\/jats:p>","DOI":"10.12968\/hmed.2018.79.9.516","type":"journal-article","created":{"date-parts":[[2018,9,6]],"date-time":"2018-09-06T10:03:19Z","timestamp":1536228199000},"page":"516-519","source":"Crossref","is-referenced-by-count":0,"title":["Emergency medicine myths and misconceptions: evaluating the evidence"],"prefix":"10.31083","volume":"79","author":[{"given":"Daniel J","family":"Kim","sequence":"first","affiliation":[{"name":"Clinical Assistant Professor, Department of Emergency Medicine, University of British Columbia, Vancouver, British Columbia V5Z 1M9, Canada and Department of Emergency Medicine, Vancouver General Hospital, Vancouver, British Columbia, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"16242","reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(15)61485-4"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.1017\/S1481803500012537"},{"key":"B3","doi-asserted-by":"publisher","DOI":"10.1001\/jamapediatrics.2015.4114"},{"issue":"4","key":"B4","doi-asserted-by":"crossref","first-page":"444","DOI":"10.3928\/1081-597X-20000701-07","volume":"16","author":"Brilakis HS","year":"2000","journal-title":"J Refract Surg."},{"key":"B5","doi-asserted-by":"publisher","DOI":"10.1097\/01.ico.0000220775.93852.02"},{"key":"B6","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(18)30479-3"},{"key":"B7","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajem.2017.05.034"},{"key":"B8","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM196808222790802"},{"key":"B9","doi-asserted-by":"publisher","DOI":"10.1001\/jamapediatrics.2015.4147"},{"key":"B10","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2016.11993"},{"key":"B11","doi-asserted-by":"publisher","DOI":"10.1016\/S0196-0644(98)70277-X"},{"key":"B12","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9394(57)90813-9"},{"key":"B13","unstructured":"Marx J, Hockberger R, Walls R. 2013.
