General Principles in the Care of the Obese Trauma Patient Objectives At the conclusion of this presentation the participant will be able to: Describe how the obesity epidemic impacts the delivery of trauma care. Discuss considerations needed in the initial assessment of the obese trauma patient
Describe the management of blunt, penetrating, and burn injures in the obese patient US Most Obese Country in World 1. United States 2. Kuwait 3. Croatia 4. Qatar 5. Egypt
6. United Arab Emirates 7. Trinidad and Tobago 8. Argentina 9. Greece 10. Bahrain Epidemiology (BMI>30) 33.8% of the population Comorbidities

cord injuries Wikimedia.org Management: Blunt Trauma Complications Overall obese patient 42% higher complication rate vs.. 32% lean population Require slightly higher total hospital LOS (24 vs.. 19 days) Higher ICU LOS (13 vs.. 10 days) Slightly higher ventilator days > 2 days vs..
lean No difference in incidence of pulmonary complications Management: Blunt Trauma Complications NIH / WHO: Obese vs.. Lean Severe Trauma Increased ICU LOS Increased propensity of: Cardiac arrest Acute Renal Failure Multisystem Organ Failure
No difference in initial leukocyte inflammatory response However, resolution of initial inflammatory response appears to be lengthened in the obese population Management: Penetrating Trauma Current Clinical issues Similar to blunt trauma management Challenges related to body habitus similarly associated in blunt trauma Prohibitory radiological imaging due to body habitus
Airway control in obese patient Prohibitive diagnostic ability (i.e. ultrasound, radiological imaging, laparoscopic intervention) all due to body habitus Management: Burns Increased surface area Increased LOS Increased complications
Summary Obesity is an increasing epidemic There are special physiological, social and emotional considerations in caring for critically injured patients that healthcare providers must understand Intervention measures specific to the management of critically injured patients is paramount to optimal outcomes
