Hypovolemic Shock - ansCaused by a decrease in the amount of circulating blood volume. In trauma typically results from hemorrhage, but can result in a precipitous loss of volume, ie vomiting or diarrhea. Burn trauma can result in hypovolemic shock from damage to the cell membranes leading to plasma and protein leakage. of body water, results in inadequate perfusion.

Graded I-V, I = minor trauma Assessment findings: signs of trauma LUQ, abdominal distention, asymmetry, abnormal contour, tenderness, guarding, rigidity, pain left shoulder when supine. CT: Hemoperitoneum. Hypodensity - represents parenchymal disruption, intraparenchymal hematoma or subcapsular hematoma. Contrast blush or extravasation
- hyperdense area that represent traumatic disruption. Active extravasation implies ongoing bleeding. Nonoperative management is preferred if hemodynamically stable, stable H/H x 12- 24 hours, minimal transfusion requirements (<2units), grade I or II without blush, age <55, alert able to assist in assessment of abdomen. Surgical options: total splenectomy for severe injury, for less severe - direct pressure packing, embolization, splenorrhaphy (suturing spleen), partial removal. Asplenic patients have difficulty destroying encapsulated bacteria - Streptococcus pneumonia, Neisseria meningitides and Haemophilus influenza. At risk for pneumococcal sepsis. Need annual flu shot and q5yr meningococcal and pneumococcal vaccines. U (AVPU) - ansUnresponsive. Does not respond to any stimuli. V (AVPU) - ansVerbal. Needs verbal stimuli to respond. (Airway adjunct may be needed to prevent tongue obstruction) A (AVPU) - ansAlert. Will be able to maintain airway once clear. A (Primary Survey) - ansAirway and alertness with simultaneous cervical spinal stabilization. Airway Assessment - ansInspect: tongue obstruction, loose/missing teeth, foreign objects, blood, vomitus, secretions, edema, burns or evidence of inhalation injury Auscultate: listen for obstructive airway sounds (ie. snoring, gurgling, stridor) Palpate: palpate for possible occlusive maxillofacial bony deformity, subcutaneous emphysema

Breathing and Ventilation Intervention - ansBreathing absent: jaw-thrust maneuver, oral airway adjunct, assist ventilation with bag- mask device, prepare for definitive airway Breathing present: NRB. Determine if ventilation effective: etCO2 35 - 45, SpO2 94% or higher. If ineffective: assist with bag-mask and determine need for definitive airway C (Primary Survey) - ansCirculation and Control of Hemorrhage Cardiogenic Shock - ansResults from pump failure in the presence of adequate intravascular volume. There is a lack of cardiac output and end-organ perfusion secondary to a decrease in myocardial contractility and/or valvular insufficiency.

Corneal Abrasion - ansDamage to the corneal epithelium. Easy to evaluate with fluorescein. Findings: photophobia, tearing, pain, injected conjunctiva (redness), lid swelling, irritation Treatment: Ophthalmic ABX, Cycloplegic agent to decrease spasms and pain, ophthalmic NSAIDS to decrease swelling, oral analgesics, Ophthalmic f/u in 24 hours. (Do NOT patch - increases infection) Corneal Foreign Body - ansRoutinely metal, plastic or wood. Findings: photophobia, pain, injected conjunctiva (redness), lid swelling Treatment: topical anesthetic, removal of foreign body, ophthalmic ABX, cycloplegics, oral analgesia Corneal Laceration - ansInvolves one or more layers of the cornea. Visualized with a slit lamp. Findings: similar to abrasion, pain out of proportion to findings, decreased vision Treatment: treat small lacerations similar to an abrasion, larger lacerations need ophthalmology referral and possible surgery Cycloplegic agent - ansCycloplegia is paralysis of the ciliary muscle of the eye, resulting in a loss of accommodation. Because of the paralysis of the ciliary muscle, the curvature of the lens can no longer be adjusted to focus on nearby objects. D (Primary Survey) - ansDisability (Neurologic Status) Disability Assessment - ansAssess GCS on arrival and repeat per policy. Assess pupils for equality, shape and reactivity (PERRL) Disability interventions - ansEvaluate for need for CT. Assume AMS to be the result of CNS injury until proven otherwise. Consider ABGs - AMS may be indicator of decreased cerebral perfusion, hypoventilation or acid-base imbalance.

Consider bedside glucose. Distributive Shock - ansOccurs as a result of maldistribution of an adequate circulating volume with a loss of vascular tone or increased permeability. Diffuse vasodilation lowers the systemic pressure, creating a relative hypovolemia or reduction of the mean systemic volume and venous return to the heart or drop in preload, resulting in distributive shock. Anaphylactic: release of inflammatory mediators, such as histamine, which contracts bronchial smooth muscle and increases vascular permeability and vasodilation. Septic Shock: systemic release of bacterial endotoxins, resulting in an increased vascular permeability and vasodilation Neurogenic shock: loss of sympathetic nervous system control of vascular tone, which produces venous and arterial vasodilation. With the loss of sympathetic nervous system input in spinal cord injury, unopposed vagal activity may result in decreased cardiac output through bradycardia. TREATMENT: increase systemic resistance, controlled volume replacement. Vasoconstriction and in some cases (neurogenic) Atropine to counteract bradycardia. E (Primary Survey) - ansExposure and Environmental Control Exposure and Environmental Control - ansCarefully and completely undress the patient. Inspect for uncontrolled bleeding and note any obvious injuries. Prevent heat loss. Hypothermia combined with hypotension and acidosis is a potentially lethal combination in the injured patient. Consider: warm blankets, keep ambient temperature warm, warm IVF, forced air warmers, radiant warming lights.
