Extremity Injuries • Open wounds – Remove contamination § Gross: remove § Smaller: irrigate with normal saline – Sterile dressing and bandage (Courtesy of 2010 North American Rescue, LLC) § Pressure dressing, if necessary § Pressure point § Tourniquet rare § Hemostatic agent International Trauma Life Support for Emergency Care Providers, Seventh Edition John Campbell • Alabama College of Emergency Physicians
Open Wounds Obvious exsanguinating hemorrhage— only time can change order of ABC to CABC. International Trauma Life Support for Emergency Care Providers, Seventh Edition John Campbell • Alabama College of Emergency Physicians
Extremity Injuries • Amputations – Disabling and sometimes life-threatening – Potential for massive hemorrhage § Most often, bleeding controlled with direct pressure © Edward T. Dickinson, MD International Trauma Life Support for Emergency Care Providers, Seventh Edition John Campbell • Alabama College of Emergency Physicians
Extremity Injuries • Amputation Management – Cover with damp sterile dressing, elastic wrap – Uniform reasonable pressure across stump – Tourniquet if bleeding absolutely not controlled (Courtesy of Stanley Cooper, EMT-P) § Rarely needed – Retrieve amputated part § In plastic bag, inside ice water International Trauma Life Support for Emergency Care Providers, Seventh Edition John Campbell • Alabama College of Emergency Physicians

Extremity Injuries • Compartment syndrome – Forearm and lower leg most common – Swelling compresses nerves and vessels International Trauma Life Support for Emergency Care Providers, Seventh Edition John Campbell • Alabama College of Emergency Physicians
Compartment Syndrome • Early symptoms – Pain – Paresthesia • Late symptoms – – – Pain Pallor Pulselessness Paresthesia Paralysis International Trauma Life Support for Emergency Care Providers, Seventh Edition John Campbell • Alabama College of Emergency Physicians
Extremity Injuries • Crush injury – Pressure on extremities for extended time § Anaerobic metabolism – Pressure released § Blood flow to crushed tissue reinstated § Toxins distributed throughout entire body • a. k. a. “Crush or Compression Syndrome” International Trauma Life Support for Emergency Care Providers, Seventh Edition John Campbell • Alabama College of Emergency Physicians
ITLS Patient Assessment • Mechanism history – – – Falls landing on feet Sitting position Fall onto wrist Fall onto ankle Shoulder involved Pelvis involved • Common injury – – – Foot, lumbar spine Knee, hip Wrist, elbow Ankle, proximal fibula Shoulder, neck, chest Pelvis, shock International Trauma Life Support for Emergency Care Providers, Seventh Edition John Campbell • Alabama College of Emergency Physicians
Extremity Trauma • ITLS Primary and Secondary Surveys – Major bleeding – DCAP-BLS-TIC – Instability – Crepitation – Joint pain – Joint movement – Distal PMS International Trauma Life Support for Emergency Care Providers, Seventh Edition John Campbell • Alabama College of Emergency Physicians © Pearson
Management • Splinting – Prevent motion in broken bone ends – Eliminate further damage – Decrease pain • Load-and-go patients – Temporary splinting with long backboard – Additional splinting during transport International Trauma Life Support for Emergency Care Providers, Seventh Edition John Campbell • Alabama College of Emergency Physicians
Splinting • Rules – Adequately visualize – Distal PMS before and after splinting § Treat neurovascular compromise – Cover open wounds with sterile dressing – Immobilize one joint above and below § Apply on side away from open wound § Pad splint well § Do not attempt to push bone ends under skin International Trauma Life Support for Emergency Care Providers, Seventh Edition John Campbell • Alabama College of Emergency Physicians
Extremity Trauma If in doubt, splint possible injury. International Trauma Life Support for Emergency Care Providers, Seventh Edition John Campbell • Alabama College of Emergency Physicians

Summary • ITLS Primary Survey has priority – Extremity trauma not usually life-threatening – Pelvic, femur fractures can be life-threatening • Proper splinting decreases further injury • Dislocations of elbows, hips, knees: – Careful splinting and rapid reduction to prevent severe disability to extremity International Trauma Life Support for Emergency Care Providers, Seventh Edition John Campbell • Alabama College of Emergency Physicians
