1 A Good Trauma Examination Gives Your Patient Increased Odds for a Good Outcome druffol@lumc.edu Lets Get it Right Trauma is a Disease Importance of Trauma Care and the trauma provider role Apply principles of primary and secondary assessments. Identify management priorities Institute appropriate resuscitation and monitoring procedures Anticipate and manage pitfalls Overview of emerging trends The leading cause of death in the first four decades of life. More than 5 million trauma-related deaths each year worldwide. Motor vehicle crashes cause over 1 million deaths per year. Injury accounts for 12% of the world s burden of disease. 1/3 of trauma deaths are related to blood loss What about this slope? 1

Its major role may be in the rapid diagnosis of hemoperitoneum. Contraindications: to the use of ultrasound are an obvious need for laparotomy and inadequate training or experience of the trauma team member performing the examination.
