Continuous erector spinae plane block: a simple, safe and effective technique for pain control in patients with rib fractures

Ribs are frequently affected after a blunt or penetrating thoracic trauma. Acute key complications associated with rib fractures include pain, hemo-pneumothorax, extrapleural hematoma, pulmonary contusion and laceration, and vascular injury. In high energy traumas, injuries to abdominal solid organs may also coexist. A later complication that can limit the weaning of patients from sedation and ventilation is neuropathic pain, which is frequently associated with rib fractures and that is often poorly responsive to oral and topical medications. The benefit of interventional nerve block procedures is still controversial. Ultrasound-guided erector spinae plane (ESP) block is a relatively new technique for thoracic analgesia that can be both a simpler and safer alternative to more complex and invasive neural blocking techniques, especially in intensive care unit patients whereas major contraindications (i.e. coagulation alteration, infection etc.) might limit the feasibility of more invasive methods, such as central blocks.
