Tracheal deviation may indicate a tension pneumothorax or massive hemothorax. What is the DOPE mnemonic? - Correct Answer-D - Displaced tube O - Obstruction: Check secretions or pt biting tube P - Pneumothorax: Condition may occur from original trauma or barotrauma from ventilator E - Equipment failure: pt may have become detached from equipment or there's a kink in the tubing Explain Hypovolemic Shock. - Correct Answer-Most common to affect a trauma pt cause by hypovolemia.. Hypovolemia, a decrease in amount of circulating blood volume, may result from significant loss of whole blood because of hemorrhage or from loss of semipermeable integrity of cellular membrane leading to leakage of plasma and protein from intravascular space to the interstitial space (as in a burn). Some causes:
  • Blood loss
  • Burns, etc. Explain Cardiogenic Shock. - Correct Answer-Syndrome that results from ineffective perfusion caused by inadequate contractility of cardiac muscle.

Some causes: MI, Blunt cardiac injury, Mitral valve insufficiency, dysrhythmias, Cardiac Failure Explain Obstructive Shock. - Correct Answer-Results from inadequate circulating blood volume because of an obstruction or compression of great veins, aorta, pulmonary arteries, or heart itself. Some causes:

  • Cardiac tamponade (may compress the heart during diastole to such an extent that atria cannot adequately fill, leading to decreased stroke volume).
  • Tension pneumothorax may lead to inadequate stroke volume by displacing inferior vena cava and obstructing venous return to right atrium.
  • Air embolus may lead to obstruction of pulmonary artery and subsequent obstruction to right ventricular outflow during systole, with resulting obstructive shock Explain Distributive Shock. - Correct Answer-Results from disruption in SNS control of the tone of blood vessels, which leads to vasodilation and maldistribution of blood volume and flow. (Neurogenic and Septic Shock). Neurogenic shock may result from injury to spinal cord in cervical or upper thoracic region. Spinal shock = areflexia and flaccidity associated with lower motor neuron involvement in complete cord injuries; reflexes return with resolution of spinal shock. Septic shock from bacteremia is distributive shock. Endotoxins and other inflammatory mediators cause vasodilation, shunting of blood in microcirculation, and other perfusion abnormalities. What is vascular response? - Correct Answer-As blood volume decreases, peripheral blood vessels vasoconstrict as a result of sympathetic stimulation via inhibition of baroreceptors. Arterioles constrict to increase TPR and BP. What is renal response? - Correct Answer-Renal ischemia activates release of renin. Kidneys do not receive adequate blood supply, renin is release into circulation.

Renin causes angiotensinogen, normal plasma protein, to release angiotensin I. Angiotensin-converting enzyme from the lungs converts into angiotensin II. Angiotensin II causes:

  • Vasoconstriction of arterioles and some veins
  • Stimulation of sympathetic nervous system
  • Retention of water by kidneys
  • Stimulation of release of aldosterone from the adrenal cortex (sodium retention hormone) *Decreased urinary output = early sign renal hypoperfusion and an indicator that there's systemic hypoperfusion. Explain adrenal gland response. - Correct Answer-When adrenal glands are stimulated by SNS, release of catecholamines (epinephrine and norepinephrine) from adrenal medulla will increase. Epi stimulates receptors in heart to increase force of cardiac contraction (positive inotropy) and increase HR (positive chronotropy) to improve cardiac output, BP and tissue perfusion. Shock stimulates hypothalamus to release corticotropin-releasing hormone that stimulates pituitary to release ACTH that stimulates adrenal gland to release cortisol. Effect of cortisol release is elevation in blood sugar and increased insulin resistance and gluconeogenesis, hepatic process to produce more sugar. Cortisol also causes renal retention of water and sodium, a compensatory mechanism to conserve body water. Explain Hepatic Response. - Correct Answer-Liver can store excess glucose as glycogen. As shock progresses, glycogenolysis is activated by epi to break down glycogen into glucose.

In a compensatory response to shock, hepatic vessels constrict to redirect blood flow to other vital areas. Explain Pulmonary Response. - Correct Answer-Tachypnea happens for 2 reasons:

  1. Maintain acid-base balance
  2. Maintain increased supply of oxygen
  • Metabolic acidosis from anaerobic metabolism will be a stimulus for the lungs to increase rate of ventilation. Increased RR is an attempt to correct acidosis + augments oxygen supply to maximize oxygen delivery to alveoli. Explain Irreversible Shock. - Correct Answer-Shock uncompensated or irreversible stages will cause compromises to most body systems.
  • Inadequate venous return
  • inadequate cardiac filling
  • decreased coronary artery perfusion
  • Membranes of lysosomes breakdown within cells and release digestive enzymes that cause intracellular damage. How would you assess a pt in hypovolemic shock? - Correct Answer-(Use Initial Assessment) and then: Inspect:

  • Surgery? ICP is a reflection of what three volumes? What happens when one increases? - Correct Answer-1. Brain
  1. CSF
  2. Blood within the nonexpansible cranial vault As volume of one increases, the volume of another decreases to maintain ICP within normal range. As ICP rises, CPP decreases, leading to cerebral ischemia and potential for hypoxia and lethal secondary insult. Hypotensive pt w/marginally elevated ICP can be harmful. Slightly elevated BP could protect against brain ischemia in a pt with high ICP. Cerebral ischemia can lead to increased concentration of CO2 and decreased concentration of O2 in cerebral vessels. CO2 dilates cerebral blood vessels = increase blood volume and ICP. What are the early signs and symptoms of increased ICP? - Correct Answer-- Headache

  • Chest wall pain
  • Paradoxical chest wall movement - the flail segment moves in during inspiration and out during expiration. Define Pneumothorax. - Correct Answer-Results when an injury to lung leads to accumulation of air in pleural space w/subsequent loss of negative intrapleural pressure. Partial or total collapse of lung may ensue. An open pneumothorax results from wound through chest wall. Air enters pleural space both through the wound and trachea. What are the S/S of a pneumothorax? - Correct Answer-- Dyspnea, tachypnea

  • Chest pain
  • Open, sucking wound on inspiration (open pneumothorax) Define tension pneumothorax. - Correct Answer-Life-threatening injury. Air enters pleural space on inspiration, but air cannot escape on expiration. Rising intrathoracic pressure collapses lung on side of injury causing a mediastinal shift that compresses the heart, great vessels, trachea and uninjured lung. Venous return impeded, cardiac output falls, hypotension results. Immediate decompression should be performed. Treatment should not be delayed. What are the S/S of a tension pneumothorax? - Correct Answer-- Severe respiratory distress
  • Markedly diminished or absent breath sounds on affected side
  • hypotension
  • Distended neck, head and upper extremity veins-may not be clinically appreciated if significant blood loss present

  • Chest pain
  • Signs of shock
  • Decreased breath sounds on injured side
  • Dullness to percussion on the injured side What is a pulmonary contusion? - Correct Answer-They occur as a result of direct impact, deceleration or high-velocity bullet wounds. It develops when blood leaks into lung parenchyma, causing edema + hemorrhage. This usually develops overtime and not immediately. What are the S/S of pulmonary contusion? - Correct Answer-- Dyspnea
  • Ineffective cough
  • Hemoptysis
  • Hypoxia
  • Chest pain
  • Chest wall contusion or abrasions What happens to a ruptured diaphragm? - Correct Answer-Potentially life- threatening, results from forces that penetrate the body. Left hemidiaphragm is more susceptible to injury because the right side is protected by the liver.
  • Herniation of abdominal contents
  • Respiratory compromise b/c impaired lung capacity + displacement of normal tissue.
  • Mediastinal structures may shift to opposite side of injury What are S/S of a ruptured diaphragm? - Correct Answer-(Anything below the nipple line and should be evaluated for potential diaphragmatic injury).
  • Dyspnea or orthopnea
  • Dysphagia
  • Abdominal pain
  • Sharp epigastric or chest pain radiating to left shoulder (Kehr's sign)
  • Bowel sounds heard in lower middle chest
  • Decreased breath sounds on injured side What are S/S with tracheobronchial injury? - Correct Answer-Blunt trauma. "Clothesline-type" injuries.
  • Dyspnea, tachypnea
  • Hoarseness
  • Hemoptysis
  • Subcutaneous emphysema in neck, face, or suprasternal area
  • Decreased or absent breath sounds
  • S/S of airway obstruction What are S/S with blunt cardiac injury? - Correct Answer-"Cardiac contusion" or "concussion." Common with MVC or falls from heights.
  • ECG (sinus tach, PVC's, AV blocks)
  • Chest pain
  • Chest wall ecchymosis What are the S/S of pericardial tamponade? - Correct Answer-A collection of blood in pericardial sac. As blood accumulates, it exerts pressure on the heart, inhibiting or compromising ventricular filling.
  • Hypotension
  • Tachycardia or PEA
  • Dyspnea
  • Cyanosis
  • Beck's Triad (hypotension, distended neck veins + muffled heart sounds)
  • Progressive decreased voltage of conduction complexes on ECG What are aortic injuries S/S? - Correct Answer-- Hypotension
  • Decreased LOC
  • Hypertension in UE's
  • Decreased quality (amplitude) of femoral pulses compared to UE pulses
  • Loud systolic murmur in parascapular region
  • Chest pain
  • Chest wall ecchymosis
  • Widened mediastinum on chest xray
  • Paraplegia How would you assess a pt with a thoracic injury? - Correct Answer-(Initial assessment) Obtain Hx. PHYSICAL: Inspection:
  • Observe chest wall
  • Assess breathing effort and RR
  • Symmetry
  • Inspect jugular veins (Distended = increased intrathoracic pressure as result of tension pneumothorax or pericardial tamponade. Flat = external jugular veins may reflect hypovolemia)
  • Inspect upper abdominal region for injury Percussion:
  • Percuss the chest (Dullness = hemothorax, Hyperresonance = pneumothorax) Palpation:
  • Palpate chest wall, clavicles and neck for:
  • Tenderness
  • Swelling or hematoma
  • Subcutaneous emphysema
  • Note presence of bony crepitus
  • Palpate central and peripheral pulses and compare quality between:
  • Right and left extremities
  • Upper and lower extremities
  • Palpate the trachea (above suprasternal notch. Trach shift may indicate late sign of tension pneumothorax or massive hemothorax)
  • Palpate extremities for motor and sensory function (lower extremity paresis or paralysis may indicate aortic injury). Auscultation:
  • Auscultate compare BP in both UE's and LE's
  • Auscultate breath sounds (decreased or absent breath = pneumo or hemothorax. Diminished BS = splinting. Shallow = b/c of pain).
  • Auscultate chest for presence of BS (diaphragmatic rupture)
  • Auscultate Heart sounds (muffled = pericardial tamponade)
  • Auscultate neck vessels for bruits (vascular injury) Diagnostic Procedures:
  • Xrays
  • Arteriography
  • Bronchoscopy and laryngoscopy
  • CT's
  • FAST
  • Labs (cardiac enzymes)
  • ECG, CVP What are S/S of Hepatic Injuries? - Correct Answer--Upper Right Quadrant Pain -Abdominal Wall Muscle Rigidity, Spasm, Involuntary Guarding -Rebound Tenderness

-Hypoactive or Absent Bowel Sounds -Signs of hemorrhage or hypovolemic shock What are S/S of Splenic Injuries? - Correct Answer--Signs of hemorrhage or hypovolemic shock -Pain in the left shoulder (Kehr's sign) when lying supine or Trendelenburg -Tenderness in the upper left quadrant -Abdominal wall muscle rigidity, spasm, or involuntary guarding S/S of Large and Small Bowel Injuries? - Correct Answer--Peritoneal irritation manifested by abdominal wall muscle rigidity, spasm, involuntary guarding, rebound tenderness, or pain -Evisceration of small bowel or stomach -Hypovolemic Shock -Gross blood from rectum S/S of Gastric Injury? - Correct Answer--Abdominal Pain -Peritoneal irritation -Evisceration of stomach -Gross blood in gastric aspirate S/S of Esophageal Injury? - Correct Answer--Subcutaneous emphysema -Peritoneal irritation -Pain radiating to the neck, chest, shoulders, or throughout the abdomen -Gross blood in gastric aspirate S/S of Renal Injuries? - Correct Answer--Hematuria -Flank or abdominal tenderness elicited during palpation -Ecchymosis over flank may occur, but normally develops 6 to 12 hours after injury How would you care for a pt with an Abdominal Injury? - Correct Answer- (Initial assessment) Obtain Hx. PHYSICAL: Inspection:

  • Observe the lower chest for asymmetric chest wall movement. -Observe the contour of the abdomen. Distention may indicate bleeding -Inspect lower chest, abdomen, flanks, and back for seat belt abrasions or soft tissue injuries
