 Despite the success of regional anesthesia, a phenomenon known as rebound pain has been shown to occur as the original block wears off7-9. Patients with blocks will experience significantly increased pain compared to those without blocks approximately 12-24 hours after surgery. This can be controlled with early narcotic administration but can be a source of significant discomfort to a patient if not recognized and treated in time. A few studies have shown that continuous infusions of various numbing agents are efficacious in prolonged pain control, even in the ambulatory setting10-12. Nevertheless, no studies have thus performed a randomized prospective control trial studying the efficacy of continuous infusion therapy on pain control following extremity fracture surgery.
