Life-threatening situation and management involves a multi-disciplinary approach following EMST guidelines.

• Obtain large-bore IV access (2 x 14G IV cannulae in ACFs) and send blood for cross-match and appropriate investigation

• Resuscitation fluids – crystalloid / colloid / blood (group specific or cross-matched dependent on urgency) administered to resuscitation end-points (MAP 60-70) in ratio of packed cells to FFP and platelets 1:1

• Avoid excessive movement of the pelvis and stabilize with sheet or commercial external pelvic stabilizer device

• CXR and secondary survey to look for other sources of bleeding

• Investigate for associated intra-abdominal or intra-pelvic injuries with FAST scan and/or CT scan if patient has stabilized with resuscitation

• Urgent consultation with interventional radiologist for angiography and embolization if other sources of bleeding excluded and if interventional radiology service available

• Urgent consultation with orthopaedic surgeon for external fixation

• Urgent consultation with general surgeon if intra-abdominal blood or evidence of intestinal perforation

• Aortic balloon occlusion also described as temporizing measure for patients in extremis from pelvic bleeding

• Analgesia

• Antibiotics if suspected / proven disruption of bowel or urinary tract

Discussion

This question would benefit from a systematic approach.

Supportive management:

A) Assessment of the airway and of the need for immediate intubation, while maintaining C-spine precautions

B) Ventilation with high FiO₂; investigation of possible aspiration with CXR and ABG.

C) Establishment of IV access and correction of hypovolemia;

urgent collection of a sample for a crossmatch of blood and urgent administration of available uncrossmatched blood.

Assess for retroperitoneal and pelvic bleeding with FAST +/- CT

D) Investigate causes of fall related to intracranial events, eg. ICH,

intoxication, seizure, etc.

E)Correct hypothermia, hypocalcemia and acidosis

Specific management:

Ensure haemostasis; the following options are available

• Blood product replacement to ensure normal coagulation function
• Pelvic binder
• Tranexamic acid and/or Factor VIIa
• Direct external compression of the aorta
• Intra-aortic balloon occlusion
• Reduction of acetabular fracture by lower limb traction
• Angioembolisation by interventional radiologist
• Surgical exploration / external fixation

What say the literature? This 2007 article essentially echoes the suggestions made by the college.
