A+|100% COMPLETE pass complete

Auscultate: Muffled heart sounds - may indicate pericardial tamponade

Palpate: carotid and/or femoral pulses for rate, rhythm, strength

Circulation and Control of Hemorrhage Interventions - ansControl and treat external bleeding: apply direct pressure, elevate bleeding extremity, apply pressure over arterial sites, consider use of a tourniquet.

2 large bore IVs, if unable consider IO, obtain labs and crossmatch.

Initiate IVF of warmed isotonic crystalloid solution. Consider blood products after 2L.

**Large volumes of fluid lead to dilution coagulopathy which worsens metabolic acidosis and may cause hypothermia. Component therapy, including administering RBC, plasma and platelets is a balanced approach so that O2 delivery is optimized, acidosis corrected and coagulopathy prevented.

Classifications of Shock - ansHypovolemic - decrease in the amount of circulating blood volume

Obstructive - obstruction in either the vasculature or heart

Cardiogenic - pump failure in the presence of adequate intravascular volume

Distributive - maldistribution of an adequate circulating blood volume (septic, anaphylactic, neurogenic)

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 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.

The liver filters out toxins, takes the nutrients and returns the blood to the heart via the hepatic veins.

Hepatocyte cells are capable of regeneration allowing the liver to repair its own tissue.

Functions: Store and metabolize lipids, transport nutrients, produce glucose and bilirubin, convert ammonia to urea, secrete electrolytes, lipids, lecithin, cholesterol and bile. Metabolizes vitamin K and produces thrombin and fibrinogen (all necessary for clotting).

Obstructive Shock - ansResults from hypo perfusion of the tissue due to an obstruction in either the vasculature or heart.

Tension pneumothorax - increased thoracic pressure leads to displacement of the vena cava, obstruction to atrial filling, decreased preload and decreased cardiac output.

Cardiac tamponade - impedes diastolic expansion and filling leads to decreased preload, strokes volume and cardiac output and ultimately end organ perfusion.

P (AVPU) - ansPainful. Responds only to painful stimuli. (Airway adjunct may be needed while determining need for intubation)

Reevaluation - ansPortable radiograph - AP chest, pelvis. Can quickly identify potentially life-threatening injuries such as pneumothorax or pelvic fracture with uncontrolled internal hemorrhage. Can also confirm placement of ET tubes, chest tubes and gastric tubes.

Consider need for transfer.

shock - ansInadequate tissue perfusion.

Spleen - ansEncapsulated organ LUQ level of 9th-11th ribs and curves around a portion of the stomach. Minimal elasticity and flexibility - most frequent injured organ in blunt 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- 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.
