Difficulty: MediumTrauma and Burns

Match the following specific clinical trauma and burn presentations with their most appropriate immediate next step in management.

  • A hypotensive patient with an anteroposterior compression pelvic ring fracture and no intra-abdominal fluid on ultrasoundPelvic angiography and embolization
  • A hypotensive patient with a stab wound to the left upper quadrant of the abdomenEmergent celiotomy (exploratory laparotomy)
  • A normotensive patient with a seatbelt sign across the abdomen and gross hematuria following a motor vehicle collisionIntravenous contrast-enhanced CT scan of the abdomen and pelvis
  • A patient with a full-thickness circumferential burn to the right upper extremity who acutely loses radial and ulnar pulsesBedside escharotomy

Answer

The correct matches align the unstable pelvic fracture with angiography, the unstable penetrating trauma with celiotomy, the stable blunt trauma with CT imaging, and the circumferential burn with escharotomy.
Each presentation dictates a specific algorithm based on ATLS protocols. Unstable penetrating abdominal trauma mandates the operating room. Unstable pelvic fractures with negative FAST mandate angiography. Stable blunt trauma mandates CT imaging. Circumferential burns with vascular compromise mandate escharotomy.

Step-by-Step Solution

1
Evaluate the hemodynamic status of each trauma patient.
Patients in hemorrhagic shock require immediate intervention to stop bleeding, while normotensive patients can safely undergo further cross-sectional imaging.
Hemodynamic stability is the primary branch point in most advanced trauma life support algorithms.
2
Identify the specific injury mechanism and involved anatomy.
Recognize that negative ultrasound in a pelvic fracture points to extraperitoneal bleeding, and circumferential burns carry a high risk of vascular compromise.
Specific anatomical injuries require targeted therapies, such as angiography for retroperitoneal arterial bleeding or surgical release for constricting burns.
