SOFT SIGNS . ZONE I – Shock responding to fluid resuscitation – Unable to palpate and observe due to bony – Small, stable hematoma skeleton – Associated nerve injuries – Highest mortality of 3 zones – Dyspnea – Mortality due to vascular injury – Subcutaneous emphysema – Hoarseness – Dysphagia – Minor hematemesis 4 Assessment Assessment . ZONE I (cont) . ZONE II – Evaluate for shock – Physical exam is possible – Hematoma resulting in respiratory compromise – Most common finding = vascular injury – Hoarseness/stridor – Subcutaneous emphysema – Hematemesis – Bruit – Dysphagia – Neuro deficit Assessment Assessment . ZONE II . ZONE III – Obvious hemorrhage – Difficult to assess with out ancillary diagnostic – Subcutaneous emphysema tests – Hoarseness/stridor – Hematemesis . Assess for neuro deficit . Signs and symptoms of shock – Bruit . Bruit – Dysphagia – Neuro deficit Diagnostics Diagnostics . ANGIOGRAPHY . COLOR FLOW DOPLER – Considered for Zone I and III – Less expensive than angiography – Invasive, costly, doesn’t always give you the – Difficult to diagnose internal carotid injuries due answer – many injuries found spontaneously to inability flex, extend or turn head if c-spine heal themselves injury is present. – Can help determine best surgical approach for repair 5 Diagnostics Diagnostics . CAROTID DUPLEX ULTRASONOGRAPHY . ESOPHAGRAMS – Used instead of angiography – Used as indicated by dysphagia, hematemesis, – Sensitive or clinical exam – Completion of test ½ time of angiography – Less expensive Diagnostics Treatment Plans . FLEXIBLE BRONCHOSCOPY . Based on physical assessment and patient – When indicated by stridor, hoarseness, stability respiratory distress, crepitus, subcutaneous .
