Since the first edition of this book six years ago, new information about many aspects of electrical and blast injuries has become available. As a result, a variety of topics have been added and updated in this second edition. You will be pleased with the results. This book explains electrical and blast injuries in a useful way to physicians and other medical personnel, military personnel, patients and their families, educators, engineers, attorneys, and other professionals. Divided into six sections for ease of use and navigation, this book covers clinical management, bioengineering, body system injuries, electrical sources, accident reconstruction, and much more! Understanding electrical injuries and explosions (electrical or bombing-related) is complex and a multi-disciplinary perspective is required. Information from both medicine and engineering is relevant to the understanding of such injuries. This new edition offers you this approach.

Topics include:

  • Basic concepts needed to understand electrical injury
  • The let-go phenomenon
  • Initial priorities: accident scene and emergency department
  • Subtle diagnostic and prognostic factors in electrical trauma
  • Treatment of specific injuries
  • Patient disposition: indications for monitoring
  • Electrical and terrorism-related explosions
  • Sympathetically mediated pain
  • Clinical approach to the electrocardiogram
  • The physiology of cardiopulmonary resuscitation
  • Electrical stimulation of the heart
