Rib Fracture
• Most common thoracic injury
• Increase morbidity and mortality
• Pulmonary function is compromised
• Acute pain control is critical
![Page 5: Rib fracture by dr.saleh bakar](https://reader033.vdocuments.us/reader033/viewer/2022060122/5595e50a1a28ab4f328b45d2/html5/thumbnails/5.jpg)
Principles• Inadequate pain control
• Inability to cough and breath deeply• Sputum retention• Atelectasis• Reduction in FRC• Compromised lung compliance• Ventilation-perfusion mismatch• Hypoxemia• Respiratory failure
![Page 6: Rib fracture by dr.saleh bakar](https://reader033.vdocuments.us/reader033/viewer/2022060122/5595e50a1a28ab4f328b45d2/html5/thumbnails/6.jpg)
Principle
• Resuscitation precedes pain relief
• Multimodal analgesia is recommended

First Aid
• Analgesia

IV Narcotics
Advantages
• Rapid onset

PCA
Advantages
• Better than IV bolus
• Continuous baseline• Patient controlled
Disadvantages
• Patient must comprehend
• Machine errors• Family interference• Weaning• Sedation

Lidocaine 5% patch Mechanism
• Penetrates the skin• Binds sodium
channels• Block influx sodium• Reduce abnormal
ectopic discharges produced by damaged nerves

Conclusions
• Lidocaine patches do not decrease narcotic pain medication use
• No difference in • pain scores• pulmonary complications• length of stay
• Should not be routinely used

Epidural
Advantages
• Improved PFTs
• Reduced airway resistance
• Improved breathing• Improved immune
response
