Brief summary

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

Detailed description

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.

Design outcomes

Primary

MeasureTime frameDescription
Average Daily Pain Score30 daysthe pain score uses the visual analog scale and ranges from 0 to 10. This is recorded by nursing at pre-specified intervals depending on level of care.

Secondary

MeasureTime frameDescription
Narcotic requirements30 daysmeasurement of daily narcotic use as 24 hour requirements of morphine equivalents, and duration of narcotic needs.
pulmonary function30 daysassessment of the incidence of pneumonia (defined clinically by the treatment team), the incidence of hypoxemia, as well as readmission for pulmonary compromise.
