Efficacy of Gabapentin vs. Placebo for Adjuvant Pain Control Following Acute Rib Fractures

A Multicenter, Randomized Controlled Trial of the Efficacy of Gabapentin vs. Placebo for Adjuvant Pain Control Following Acute Rib Fractures

A Multi-center, Randomized Controlled Trial of the Efficacy of Gabapentin vs. Placebo for Adjutant Pain Control Following Acute Rib Fractures.

Traumatic rib fractures are a tremendous source of pain which can limit respiratory function and overall recovery. Numerous multimodal pain management strategies have been employed with varying success; however, narcotics remain the mainstay of treatment. Beyond the acute side effects of narcotics, including altered mental status, depression of respiratory drive, and constipation, there is a substantial risk of long term dependency. Recently, loco-regional blockade and non-narcotic adjuncts have received increasing support within the literature. Gabapentin has been used extensively as a non-narcotic adjunct to analgesia regimens in the acute and chronic settings, however its ability to better control pain secondary to traumatic rib fractures has never been studied .

The primary aim is to assess the efficacy of gabapentin as an analgesic after rib fractures. Secondary aims are to assess the effect on pulmonary function and other known complications following rib fractures.

The hypothesis is gabapentin will improve pain control as measured by lower pain scores and lower narcotic needs. The investigators plan to test this hypothesis by recruiting trauma patients with rib fractures, and randomly assign them to gabapentin versus a placebo.
