Assessment of postoperative analgesia after application of ultrasound-guided regional anesthesia for surgery in a swine femoral fracture model.

Management of pain in research swine used for studies involving painful procedures is a considerable challenge. Here we assessed whether a regional anesthesia method is effective for pain control of hindlimb injuries in pigs used for research in bone fracture healing. For this randomized controlled study, we administered regional anesthesia before an experimental femoral injury was produced.

The evolution and practice of acute pain medicine.

Background: In recent years, the field of acute pain medicine (APM) has witnessed a surge in its development, and pain has begun to be recognized not merely as a symptom, but as an actual disease process. This development warrants increased education of residents both in the performance of regional anesthesia as well as in the disease course of acute pain and the biopsychosocial mechanisms that define interindividual variability.

Review Summary: We reviewed the organization and function of the modern APM program.

Ultrasound-guided peripheral nerve stimulator placement in two soldiers with acute battlefield neuropathic pain.

Acute peripheral neuropathic pain after combat-related polytrauma is a common occurrence in the United States military that is often refractory to current drugs and regional anesthesia. Both spinal cord and peripheral nerve stimulation are successfully used for chronic neuropathic pain states, but are not reported for acute neuropathic pain. We present 2 cases of percutaneous ultrasound-guided sciatic peripheral nerve stimulation placement in soldiers who had conditions precluding them from spinal cord stimulation placement.
