What is the treatment for a patient with a rib fracture?

Treatment of Rib Fractures

The optimal treatment for patients with rib fractures is a multimodal analgesic approach, with regular administration of intravenous or oral acetaminophen as first-line treatment, followed by NSAIDs such as ketorolac for moderate pain, and regional anesthetic techniques (thoracic epidural or paravertebral blocks) for severe pain or high-risk patients. 1, 2

Risk Assessment

Risk factors that predict increased complications in patients with rib fractures include:

• Age >60 years 3, 1
• Low oxygen saturation (SpO2 <90%) 3, 1
• Obesity or malnutrition 3, 1
• Multiple rib fractures (2-3 ribs), flail segment, or pulmonary contusion 3, 1
• Smoking or chronic respiratory disease 1
• Anticoagulation therapy 3, 1
• Major trauma 3, 1

Analgesic Management

First-Line Treatment

• Acetaminophen (oral or intravenous) every 6 hours 1, 4
  • Oral acetaminophen is equivalent to intravenous acetaminophen for pain control in elderly patients with rib fractures, with no difference in morbidity or mortality 3, 4
  • Should be used as the foundation of multimodal analgesia 5

Second-Line Treatment

• NSAIDs such as ketorolac or ibuprofen for moderate pain 1, 2, 6
  • Ketorolac can be initiated with IV or IM dosing (60 mg IM every 15-30 minutes, maximum 120 mg/day) for patients 17-64 years 2
  • Early IV ibuprofen therapy significantly decreases narcotic requirements and can reduce hospital length of stay 6
  • Avoid NSAIDs in patients with aspirin/NSAID-induced asthma, pregnancy, or cerebrovascular hemorrhage 2

Third-Line Treatment

• Low-dose ketamine (0.3 mg/kg over 15 minutes) as an alternative to opioids 3, 1
  • Provides comparable analgesic efficacy to morphine but has more psycho-perceptual adverse effects 3

Advanced Pain Management for Severe Pain or High-Risk Patients

• Regional anesthetic techniques are the gold standard for severe rib fracture pain 7, 8
  • Thoracic epidural analgesia (TEA) provides more comprehensive pain relief compared to parenteral opioids 7
  • Paravertebral blocks (PVB) are recommended for patients who are anticoagulated or have contraindications to TEA 7
  • Serratus anterior plane blocks (SAPB) and erector spinae blocks (ESPB) are practical alternatives with lower incidences of adverse effects 8

Surgical Management

• Surgical fixation should be considered for patients with:

  • Flail chest (unstable chest wall) 3, 1
  • Severe refractory pain 3, 1
  • Chest wall deformity 3, 1

• Timing of surgical intervention:

  • Most favorable outcomes when performed within 72 hours of injury 3, 1
  • In patients over 60 years old, conservative management may show benefits in terms of hospital stay and mechanical ventilation duration 3, 1

Recovery Timeline

• Rib fractures typically heal within 6-8 weeks, but complete recovery may take up to 2 years in some patients 1
• Pain scores typically improve significantly by 4 weeks post-injury with appropriate management 1
• Functional recovery with return to normal activities may take 8-12 weeks for simple fractures and up to 6 months for complex injuries 1

Common Pitfalls and Caveats

• Inadequate pain control leads to shallow breathing, atelectasis, and pneumonia 7
• Overreliance on opioids can lead to respiratory depression, especially in elderly patients 7, 5
• Surgical fixation is not universally beneficial - patient selection is crucial 3
• NSAIDs should be used with caution in elderly patients and those with renal impairment 2
• Regional anesthetic techniques require skilled practitioners and may have contraindications 7, 8
