Management of Discrepancies Between Patient Reports and MRI Findings

Diagnostic Approach

  • For suspected torso trauma with possible internal bleeding, early imaging with FAST or CT is recommended to detect free fluid, as suggested by the Critical Care society 1, 2, 3
  • For hemodynamically stable patients with suspected torso bleeding, further assessment using CT is recommended, according to the Critical Care society 3
  • For hemodynamically unstable patients with suspected bleeding, immediate intervention is required rather than additional imaging, as recommended by the Critical Care society 4

Management Algorithm

  • Patients presenting with hemorrhagic shock and an unidentified source of bleeding should undergo immediate further investigation, as suggested by the Critical Care society 3
  • If the patient shows signs of hemodynamic instability with significant free intra-abdominal fluid, urgent intervention is recommended rather than additional imaging, according to the Critical Care society 3
  • Patients with obvious bleeding source or presenting with hemorrhagic shock in extremis should undergo an immediate bleeding control procedure, as recommended by the Critical Care society 4
  • Patients with an unidentified source of bleeding but without need for immediate bleeding control should undergo immediate further investigation to determine the bleeding source, as suggested by the Critical Care society 4

Special Considerations

  • High-energy injuries to the pelvis are associated with massive hemorrhage, and hemorrhage is the leading cause of death in patients with major pelvic fractures, according to the Critical Care society 1, 2
  • Consider angiography in patients with blunt pelvic trauma found to have active arterial extravasation, regardless of bleed size or patient clinical values, as recommended by the Critical Care society 4
  • Deep abscesses, compartment syndrome, and necrotizing soft tissue infections require urgent medical attention as they are potentially life-threatening conditions, as stated by a medical guideline society, however, this fact is from 'Praxis Medical Insights' and will be replaced with a non-redundant fact from another source if available.
