Study Notes
Management of Shock
- Hemorrhage is the most common cause of traumatic hypotension and shock, second only to head injury in trauma mortality.
- Other causes include abnormal pump function (myocardial contusion, pericardial tamponade, pre-existing cardiac disease, or coronary/valve injury), pneumothorax/hemothorax, and spinal cord injury.
- Anaphylaxis and sepsis (except in unrecognized bowel injury) are less common initial causes, occurring days after trauma.
- Surgical control of bleeding is the primary goal; nonsurgical methods (e.g., finger compression, tourniquet) may be used temporarily.
- Tourniquets should be removed as soon as possible to prevent nerve damage, skin necrosis, or limb ischemia.
- Shock severity evaluation considers mechanism, injury pattern, prehospital/ED hemodynamic data, and response to fluid resuscitation.
- High-impact injuries (falls, high-energy collisions, high-velocity gunshot wounds) and non-compressible injuries (thoracoabdominal, pelvic) frequently cause major bleeding requiring immediate evaluation.
- FAST, CT, or diagnostic peritoneal lavage (rarely) assess intra-abdominal fluid.
- Hemodynamically unstable patients with intra-abdominal injuries require immediate surgical intervention.
- Stable patients with high-risk mechanisms/injury will require further evaluation, likely by CT.
- Early whole-body CT scans are valuable for whole-body scanning.
- Clinical signs (tachycardia, blood pressure) can be misleading, particularly in elderly patients.
- Activating Bezold–Jarisch reflex or increased vagal tone can prevent tachycardia, and other conditions can mask hypovolemia.
- Tissue injury/pain can increase catecholamines leading to seemingly normal vital signs in absence of hypovolemia, decreasing blood flow to the splanchnic (gut) area, increasing septic risk.
- Normal vital signs should not automatically assume normovolemia, especially in the elderly (age over 65), as they are more prone to underlying hypoperfusion even with seemingly normal blood pressure.
- A systolic blood pressure (SBP) of 110 mmHg is considered the optimal target for trauma patients, particularly for patients over 65. Aiming for 90 mmHg is still used for younger patients.
- Traditionally, 90 mmHg is the "lower limit" for SBP, but critically injured patients with an SBP of 110mmHg or lower have greater mortality and worse blood chemistry (base deficit & higher lactate).
- Although traditional vital signs are unreliable, heart rate, blood pressure, pulse pressure, respiratory rate, urine output, and mental status still guide evaluation of shock.
Massive Transfusion Protocol (MTP)
- MTPs activate multiple protocols to address major traumatic hemorrhages in the ED and OR.
- MTPs prioritize administering a limited amount of crystalloid solutions, frequent FFP or PF24 and PRBCs administration.
- Platelets and cryoprecipitate are also routinely given.
- Elderly (age > 65) patients tolerate MTP as well as young counterparts.
- Pediatric MTP (high injury severity score, or blood volume over 40mL/Kg) differs from adults due to significant differences in size, injuries, physiology, and demographics.
- The ideal 1:1:1 ratio of PRBCs:FFP:platelets translate to children as 20 mL/kg PRBCs, 20 mL/kg FFP, and 10 mL/kg platelets; careful research is still needed on this ratio.
- Coagulopathy assessment (e.g., thromboelastography) is preferred over traditional coagulation tests (e.g., PT, PTT) in pediatric trauma evaluation.
- Avoid "vicious cycle" (acidosis, hypothermia, dilutional coagulopathy).
Coagulopathy in Trauma
- Trauma patients are frequently hypercoagulable, but 10 to 15% develop severe hypocoagulability.
- Fluid resuscitation and PRBCs can worsen existing or newly developed hypocoagulability.
- Hemorrhage/intravascular coagulation further worsens this process.
- Coagulopathy has two components (Acute Traumatic Coagulopathy and Resuscitation-associated Coagulopathy).
- ATC occurs soon after injury and independent of hypothermia or fluid dilution.
- RAC is due to hypothermia, fluids, and other resuscitation factors.
- Initiating immediate (preferably prehospital) resuscitation with hemostatic fluids & PRBCs can improve patient outcomes; a high ratio (e.g. 1:1:1) is often used.
Additional Considerations in Trauma (updated)
- Severe pulmonary contusion, respiratory insufficiency/failure despite analgesics, severe shock, severe head injury/surgery, airway obstruction, and significant pre-existing pulmonary disease indicate intubation and ventilation.
- Prevent hyperventilation in head injuries.
- Low tidal volumes (6-8 mL/kg) and moderate PEEP are best for intubated patients.
- Airway pressure release ventilation (APRV) improves oxygenation, thus reducing intubation time and ventilator-associated pneumonia.
- Severe unilateral pulmonary contusion can use differential lung ventilation.
- Bilateral severe contusions with life-threatening hypoxemia can use high-frequency jet ventilation.
- Systemic air embolism (penetrating lung trauma or blast injuries) requires immediate surgical intervention & respiratory strategies; TEE can help with visualization and management.
