- Brief Summary
Determine the effect of using oral pregabalin on the analgesic effects of IV infusion of morphine in patients with multiple fracture ribs.
- Detailed Description
Blunt chest trauma accounts for a significant proportion of debilitating and life-threatening injuries. Rib fractures are notoriously painful and can lead to prolonged hospitalization,contribute to the development of pneumonia and respiratory failure, and delay outpatient recovery significantly.Flail chest, along with chest wall deformity, the most severe of chest wall injuries, is associated with significant acute morbidity and mortality.Flail chest injury has been associated with a high mortality rates historically and up to 16 % more recently. In-patients with physiologic flail visibly apparent paradoxical chest wall motion leads to inefficient respiratory effort and compression of the lung and diminishes the negative intra thoracic pressure essential for the passive movement of air into the bronchial tree. Atelectasis leads to increased lung resistance and decreased compliance, making the work of breathing much more difficult. Loss of the ability to generate negative intra thoracic pressure with breathing also impairs venous return, a passive process dependent on the negative intra thoracic pressure generated with each breath. In patients without a visible flail segment, i.e., an anatomic or radiologic flail,the physiologic derangements can be similarly destructive.There is mounting evidence that a patient's perception of pain in the early post-injury period is associated with chronic pain development . A recent prospective study of rib fracture patients found that pain and disability at 8 weeks post injury could be predicted by the pain intensity within the first few days after injury . Interestingly, the number of fractures and the bilaterality of fractures were not predictive. Thus, pain management in the early post-injury setting is likely paramount to obtaining a more favorable recovery. Opioids, are traditional first-line therapy for acute rib fracture pain. But because of chronic misuse potential and central desensitization concerns, pain researchers and clinicians are increasingly recommending that opioids be used only in combination with other analgesic modalities such acetaminophen, nonsteroidal anti-inflammatory medication(NSAID), the anticonvulsants gabapentin and pregabalin,and the topical lidocaine patch
