Summary

Rib fractures are common injuries in accident patients and can be associated with significant pain during recovery. If poorly controlled, pain from splinting due to rib fractures can result in difficulty in breathing leading to incomplete expansion of lung, and even the need to put a patient on a ventilator to help them breathe. Therefore, pain control is critical in managing patients with rib fractures. To date, many studies have shown the effectiveness of continuous intercostal nerve blockade (a slow release of pain medications at the site of injury that prevents the transmission of pain signals). This approach has never been studied in a randomized fashion in rib fracture patients, and has never been compared to patient-controlled narcotic pain medication, commonly used at many hospitals. The purpose of this study is to evaluate the effectiveness of the placement of an elastomeric infusion pump (a small, external, wearable balloon used to deliver medication over time) attached to a continuous infusion catheter or "soaker" catheter (a tube which releases the pain medication through tiny holes in it, right at the site of injury) to deliver local anesthetic medication to reduce pain caused by two or more rib fractures.

Detailed description

Treatment of rib fractures using an elastomeric infusion pump (a small, external, wearable balloon used to deliver medication over time) containing pain medication and a continuous infusion catheter or "soaker" catheter (a tube which releases the pain medication through tiny holes in it, right at the site of injury) placed in the extrathoracic paraspinous space (a site in the back that is near the broken ribs) to create a continuous intercostal nerve block is relatively novel. Truitt and colleagues have published two studies evaluating the effectiveness of this approach. A pilot study on 30 patients was published in 2010 showing that placement of these catheters was a safe, viable and effective procedure, and resulted in decreased pain scores in rib fracture patients. A second study included 102 patients studied prospectively (from the time of admission to the hospital) comparing epidural anesthesia (an injection of anesthetic into the spine) with local catheter delivery in a non-randomized fashion in 2011. This approach is beginning to be more widely used, but has never been studied in a randomized fashion, and has never been compared to patient-controlled analgesia (PCA, delivery of a pain medication by the push of a button), commonly used at many hospitals. We hypothesize that accident patients with two or more rib fractures who receive pain control through the continuous infusion system will achieve improved pain control in a dose-dependent fashion, improved lung function, and therefore, will require less narcotic pain medication, achieve discharge criteria earlier and have a shorter hospital length of stay in comparison to patients treated with PCA alone.
