Practical experience in the initial treatment of injured patients is not easily available to the medical student. The small number of injured patients available for observation in a short time, the fact that the patients do not necessarily arrive in regular teaching hours, and the large number of students present in teaching groups compound this difficulty. Specialized instruction in these subjects is therefore important. The acquisition and use of teaching aids facilitate precise and efficient presentation of the material. We present teaching aids specifically prepared for instruction in the initial management of the injured and in resuscitation procedures. These aids include a library of video recordings documenting important emergency procedures, a TV camera used for filming these procedures, a collection of slides on the subject of emergency medicine and recent injuries, mannequins for instruction in cardiopulmonary resuscitation (CPR), utilization of the hospital's animal research laboratory for instruction in critical procedures such as venous cutdown, chest drainage, etc., and simulated computer programs.
