Observational Study
National Perioperative Outcomes for Intrathecal Pump, Spinal Cord Stimulator, and Peripheral Nerve Stimulator Procedures.
There is abundant literature on the long-term complications of intrathecal pumps (ITP), spinal cord stimulators (SCS), and peripheral nerve stimulators (PNS) used in the treatment of chronic pain. There is less information, however, on the perioperative complications of these procedures. ⋯ Databases such as NACOR can provide rich information on ITP, SCS, and PNS for physicians performing these procedures. In this sample, ITP procedures, performed on the patients with the most severe cormobidities and often-requiring general anesthesia, were the most likely to be associated with hemodynamic instability, inadequate pain control, and extended PACU stays. Complications relating to the ITP are also the most common reason for an operation. These findings underscore the importance of proper patient selection for ITP and other implantable pain devices, in particular for patients with malignant pain or multiple co-morbidities. To identify the root causes of complications, additional information is needed on the procedure performed (e.g., an implant vs a revision), the surgical technique used, and the device implanted, as well as on specific patient comorbidities. Such information will likely become more available as resources like NACOR expand and as electronic medical record systems and coding become more integrated.

Observational Study
Acute Back Pain Following Surgery under Spinal Anesthesia.
The purpose of this study was to determine the factors having a role in the occurrence of acute back pain following spinal anesthesia. ⋯ Contrary to the common belief, it is demonstrated in this study that number of lumbar punctures, method of approach and position of the spinal anesthesia, age, sex, surgical position, and the type of the surgery did not correlate with occurrence of acute back pain following spinal anesthesia.

Some patients will experience post-operative back pain following lumbar discectomy, and the potential sources for that pain are poorly understood. One potential source is the vertebral endplates. The goal of this study was to document the changes that occur in lumbar endplates following discectomies, and to assess associations between endplate changes and clinical outcomes. ⋯ This study documents lesion characteristics in detail and supports that osseous defects in the endplates at the level of a lumbar discectomy may be a relatively common finding following surgery, along with disc height loss, loss of disc signal intensity, and Modic changes. The clinical significance of these imaging findings could not be conclusively determined in this study.

Case Reports[Management of transient radicular pain after receiving an epidural blood patch for headaches due to spontaneous intracranial hypotension].
Spontaneous intracranial hypotension headache is an uncommon disease that resolves spontaneously in most of the cases and in a short period of time. The initial treatment should be symptomatic. In some patients the symptomatology is extremely disabling, and in these cases both the diagnosis and treatment may be performed by an epidural blood patch. ⋯ Considering the symptomatology and the uncontrolled pain, the Pain Unit of our hospital performed an epidural blood patch. In the first 24h the patient reported a remarkable relief of both headache and diplopia but developed a left lumbar radiculopathy that was treated successfully with supportive measures. Transient lumbar radiculopathy is a common and acceptable event secondary to the use of epidural blood patch as a treatment for spontaneous intracranial hypotension headache.
