Rectus sheath nerve block for analgesia & incarcerated hernia reduction in the emergency department.

Background: Patients who present to the emergency department (ED) with incarcerated or strangulated ventral hernias are often in significant pain. Furthermore, even with procedural sedation, reduction itself also causes substantial pain. Hernias that cannot be reduced at the bedside with intravenous opioids or procedural sedation will require emergent surgery, which contributes to morbidity and mortality, especially in high-risk populations.

Case report: We present the case of a 94-year-old man with an incarcerated ventral hernia that was reduced in the ED with the aid of a rectus sheath block, ultimately avoiding the need for emergent surgical intervention.

Implications: Ultrasound can visualize and diagnose an incarcerated hernia, and a bilateral rectus sheath block can be performed in the ED to anesthetize the peritoneal wall, paralyze abdominal musculature, and achieve nearly painless hernia reduction.
