Multicenter Study
Pre-emptive and multi-modal perioperative pain management may improve quality of life in patients undergoing spinal surgery.
Compared to an abundance of data on surgical techniques for degenerative spine conditions and the outcomes thereof, little is available to guide optimal perioperative pain management after spinal surgery. The aim of this study was to survey patterns of perioperative pain management after spinal surgery and to investigate the effects of perioperative pain management, such as pre-emptive analgesia and multi-modal postoperative pain management, on acute postoperative satisfaction, pain reduction, and health-related quality of life in patients undergoing spinal surgery. ⋯ Pre-emptive analgesia and multi-modal pain management after spinal surgery may lead to better health-related quality of life, greater patient satisfaction, and less postoperative pain.

Case Reports
Using pulsed radiofrequency ablation to treat pain associated with a tumor involving the brachial plexus.
Pain associated with cancer is often difficult to treat, even more so when tumors involve peripheral nerves. Therapy is complex and often requires a multimodal approach that can include medications, radiation, and interventional techniques. These components are utilized with variable success, but are also limited by known complications or adverse effects. ⋯ Pulsed radiofrequency is a poorly understood technology that has increasing evidence for certain pain conditions; however, for cancer and peripheral nerves the evidence is slim to none. Our case presents a successful use for pain management of a brachial plexopathy due to a tumor. We propose that pulsed radiofrequency may present a non-neurodestructive pain management technique for tumors involving peripheral nerves, though more data is definitely needed.

Meralgia paresthetica (MP) is a mononeuropathy of the lateral femoral cutaneous nerve (LFCN) characterized by pain, numbness or paresthesia on the anterolateral aspect of the thigh. Though several contributing factors have been identified, the cause of its idiopathic form still remains unclear. Anatomic and clinical studies have demonstrated a variable course for the LFCN and have suggested a contribution to the pathogenesis of MP. ⋯ The results of this study demonstrate a significantly different course of the LFCN, closer to the ASIS in patients with idiopathic MP.

In the United States, millions of Americans are affected by chronic pain, which adds heavily to national rates of morbidity, mortality, and disability, with an ever-increasing prevalence. According to a 2011 report titled Relieving Pain in America: A Blueprint for Transforming Prevention, Care, Education, and Research by the Institute of Medicine of the National Academies, pain not only exacts its toll on people's lives but also on the economy with an estimated annual economic cost of at least $560 - 635 billion in health care costs and the cost of lost productivity attributed to chronic pain. Intravenous infusions of certain pharmacologic agents have been known to provide substantial pain relief in patients with various chronic painful conditions. ⋯ The following intravenous infusions used to treat the aforementioned chronic pain conditions will be reviewed: lidocaine, ketamine, phentolamine, dexmedetomidine, and bisphosphonates. This overview is intended to familiarize the practitioner with the variety of infusions for patients with chronic pain. It will not, however, be able to provide guidelines for their use due to the lack of sufficient evidence.

Randomized Controlled Trial
Transforaminal hypertonic saline for the treatment of lumbar lateral canal stenosis: a double-blinded, randomized, active-control trial.
Degenerative lumbar spinal stenosis is one of the most common causes of chronic lower back pain and radiculopathy. Spinal stenosis is anatomically classified as central and lateral spinal canal stenosis. Many treatment modalities and techniques, including surgery and epidural injection, have been used to manage the pain. However, the effect of hypertonic saline injection via the transforaminal approach has not yet been studied. ⋯ Superior short-term pain relieving efficacy, but limited long-term effects of hypertonic saline, when added to TFEIs.
