What is the appropriate management for a hemodynamically stable motor vehicle accident rollover patient with T5‑level paraplegia and bedside ultrasound showing free fluid around a normal‑size spleen?

Management of Hemodynamically Stable MVA Rollover Patient with T5 Paraplegia and Splenic Injury

This patient requires immediate operative management (splenectomy) despite hemodynamic stability due to the combination of severe spinal cord injury and splenic trauma with hemoperitoneum. 1

Critical Decision Point: Spinal Cord Injury Changes Management

The presence of T5-level paraplegia fundamentally alters the standard non-operative approach for splenic trauma. Patients with concomitant spinal cord injuries and high-grade splenic injuries (AAST-OIS grade IV-V) demonstrate survival benefit with immediate splenectomy over non-operative management (NOM). 1

Why Spinal Cord Injury Mandates Surgery

• Unreliable clinical examination: The paraplegia masks abdominal pain and peritoneal signs, eliminating the ability to perform serial clinical examinations—the cornerstone of successful NOM 1
• Hemodynamic monitoring unreliability: Spinal shock and autonomic dysfunction from T5 injury can mask signs of ongoing hemorrhage, making traditional hemodynamic parameters unreliable 1
• Increased NOM failure risk: Even in centers with angioembolization capability, the inability to clinically monitor these patients increases the danger of delayed recognition of bleeding 1

Standard NOM Criteria (Not Applicable Here)

For context, typical NOM candidates require 1:

• Hemodynamic stability (SBP >90 mmHg without ongoing resuscitation)
• Ability to perform serial clinical examinations
• Immediate access to OR, interventional radiology, and blood products
• No other injuries requiring laparotomy
• Intensive monitoring capability

This patient fails the serial examination criterion due to paraplegia.

Operative Approach

Immediate Actions

• Activate massive transfusion protocol and ensure blood products available 1
• Proceed directly to operating room for exploratory laparotomy and splenectomy 1
• Avoid CT scanning if it delays definitive management—ultrasound has already identified the injury 1

Surgical Considerations

• Splenectomy is preferred over splenic salvage attempts in this unstable monitoring scenario 1
• Laparoscopic approach is contraindicated in trauma with hemoperitoneum 1
• Assess for associated hollow viscus injuries (5% incidence with splenic trauma) 1

Post-Splenectomy Management

Infection Prophylaxis (Critical in Splenectomized Patients)

• Vaccinate against encapsulated bacteria (S. pneumoniae, H. influenzae, N. meningitidis) starting 14 days post-splenectomy 1
• If discharge before day 14, vaccinate before discharge to avoid missing the window 1
• Seasonal influenza vaccination for patients >6 months 1
• Antibiotic prophylaxis for any unexplained fever, malaise, or constitutional symptoms 1
• Educate patient and primary care provider about overwhelming post-splenectomy infection (OPSI) risk 1

VTE Prophylaxis

• Mechanical prophylaxis immediately (not contraindicated by splenectomy) 1
• LMWH-based pharmacologic prophylaxis should start as soon as surgical hemostasis confirmed 1
• Trauma patients transition to hypercoagulable state within 48 hours 1

Common Pitfalls to Avoid

• Do not attempt NOM based solely on hemodynamic stability when neurologic injury prevents examination 1
• Do not delay surgery for additional imaging—ultrasound showing free fluid is sufficient in this context 1
• Do not rely on heart rate or blood pressure as sole indicators of stability in spinal cord injury patients 1
• Do not forget post-splenectomy vaccinations—this is a life-threatening omission 1

Special Note on Angioembolization

While angioembolization is valuable for NOM in appropriate candidates 1, it is not appropriate here because:

• The patient cannot be clinically monitored due to paraplegia 1
• Angioembolization requires subsequent intensive monitoring with serial examinations 1
• Failure to recognize delayed bleeding could be catastrophic 1
