Continuous Intercostal Nerve Blockade for Traumatic Rib Fractures
Prime "Rib" Time: Randomized Control Trial Evaluating the Use of Continuous Intercostal Nerve Blockade for Traumatic Rib Fractures
Study Overview
Status
Conditions
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.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Narcotic Use
Time Frame: 3 days or hospital length of stay, if less than 3 days
|
Quantity of systemic narcotic used (hydromorphone hydrochloride, Dilaudid) averaged per day over the length of hospital stay, in mg/24 hours.
|
3 days or hospital length of stay, if less than 3 days
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Time to Improvement in Pulmonary Function
Time Frame: 3 days or hospital length of stay, if less than 3 days
|
Determine the impact of catheter-infused medications on maximal inspiratory lung volume measured by incentive spirometer (IS) as a change from baseline at 24, 48, 72 hours and at 3 days post catheter placement or at discharge (or PCA placement in comparator group).
Endpoint will be the time to improvement of vital capacity to greater than 1.4 liters (or 15 mL/kg).
|
3 days or hospital length of stay, if less than 3 days
|
Time to Improvement in Pain Intensity
Time Frame: 3 days or hospital length of stay, if less than 3 days
|
Determine the impact of catheter-infused medications on self-reported pain intensity reported as a change from baseline (admission) at 24, 48, 72 hours and at 3 days post catheter placement or at discharge (or PCA placement in comparator group) on a 0-10 point Likert scale, with 0=no pain, and 10= the worst pain ever.
Response will be defined as time to a decrease of at least two points on the scale.
|
3 days or hospital length of stay, if less than 3 days
|
Morbidity
Time Frame: 3 days or hospital length of stay, whichever is longer
|
Collection of complications observed at any point during the hospital admission that included randomization, including pneumothorax, hemothorax, acute respiratory distress syndrome, pneumonia, empyema, need for tracheostomy, need for mechanical ventilation, length of time on mechanical ventilation, and an assessment of the degree of association of each event with the catheter insertion procedure or with underlying trauma.
Each of these outcomes will be scored as yes/no.
|
3 days or hospital length of stay, whichever is longer
|
Mortality
Time Frame: 30 days
|
All cause death, death associated with infusion catheter, within 30 days from date of randomization.
This outcome will be scored as yes/no and cause of death will be collected.
|

|
Hospital Length of Stay
Time Frame: from randomization to discharge, usually within the range of 5-15 days
|
Integer days of inpatient admission in the hospital stay that included randomization.
|

|
Surgical Intensive Care Unit (SICU) Length of Stay
Time Frame: from admission to Surgical Intensive Care unit to discharge from Surgical Intensive Care Unit
|
Integer days of admission to the surgical intensive care unit.
For patients not requiring admission to surgical intensive care, patient is not analyzed.
Usual range is 3-5 days.
