Older age increases mortality risk per trauma registry observations
Pathophysiology
Pathophysiology
Pain and mechanics
Splinting reduces tidal volume
Atelectasis risk
Secretion retention
Impaired cough
Pneumonia risk
Co injuries
Lung parenchymal injury from blunt force
Pleural space injury causing pneumothorax or hemothorax
Therapeutic Considerations
Therapeutic principles
Analgesia improves ventilation
Reduced atelectasis
Improved cough effectiveness
Multimodal approach
Opioid sparing reduces respiratory depression
Regional anesthesia improves pulmonary mechanics
Ventilatory support as bridge
NIV reduces work of breathing in selected patients
Early escalation prevents fatigue
Patient Discharge Instructions
copy discharge instructions
Discharge plan
Pain control regimen
Acetaminophen schedule
NSAID schedule if safe
Opioid rescue only if needed
Breathing exercises
Incentive spirometry while awake
Deep breathing and coughing routine
Activity guidance
Avoid heavy lifting until improving
Gradual return to activity
Ice and positioning
Ice to tender area 15 to 20 minutes several times daily
Sleep upright if helpful
Return to ED immediately
Breathing worsening
New or increasing shortness of breath
SpO2 decline if home oximeter
Chest complications
New chest tightness not reproducible by pressing on ribs
Coughing up blood
Infection signs
Fever
Productive cough
Pain escalation
Pain preventing deep breathing despite medications
Confusion or excessive sleepiness after pain meds
