Neuromodulation, including spinal cord stimulation and peripheral nerve field stimulation, has been used with success in treating several painful conditions. The FDA approved the use of neuromodulation for a few indications. We review evidence for neuromodulation in treating some important painful conditions that are not currently FDA approved. ⋯ This review article shows compelling evidence based on clinical trials that neuromodulation can be of benefit for patients with serious painful conditions that are not currently approved by the FDA.

Intravenous (IV) analgesia has particular advantages in the immediate postoperative period. For example, IV administration results in a faster onset of pain relief and results in more predictable pharmacokinetics than does administration by other routes. It also allows for convenient dosing before or during surgery, permitting the initiation of effective analgesia in the early phase of the postoperative period. ⋯ Some studies show that IV oxycodone may be associated with greater pain control, fewer or less severe adverse events, and faster onset of action, although the results are not consistent across all studies. Oxycodone has been reported to be safe in the geriatric and other special populations when adequate clinical adjustments are made. Thus, the clinical reports and oxycodone's pharmacologic profile make intravenous oxycodone a potentially important "new" old drug for postoperative pain control.

Ketamine is a commonly used analgesic agent in the management of both acute and chronic pain. While dose-dependent side effects are well described, allergy to ketamine is extremely rare. ⋯ This case represents a likely immunoglobulin E-mediated type I hypersensitivity reaction to ketamine, supported by elevated tryptase levels and positive intradermal skin testing. The interpretation of these results and likely mechanism of the hypersensitivity reaction are described. The patient and treating team were advised against subsequent use of ketamine, due to the risk of serious adverse systemic reaction with repeat exposure.

Randomized Controlled Trial
Local Administration of Methylcobalamin and Lidocaine for Acute Ophthalmic Herpetic Neuralgia: A Single-Center Randomized Controlled Trial.
To determine the therapeutic efficacy of combined methylcobalamin and lidocaine for acute ophthalmic herpetic neuralgia (AOHN). ⋯ Methylcobalamin combined with lidocaine mediated detumescence and improved cutaneous healing of the affected area, as well as a significant and sustained analgesic effect on AOHN. The incidence of PHN was also significantly decreased. Local methylcobalamin intervention within 4 to 7 days of onset may be an effective therapeutic option for AOHN.

Chronic neuropathic groin pain is a sequela of hernia surgery that occurs at unacceptably high rates, causing widespread impacts on quality of life. Although the medical community is beginning to recognize the role of surgical technique in the initiation and maintenance of postherniorrhaphy neuropathic pain, little information exists regarding pain management strategies for this condition. This review presents a summary of the pain condition state, its treatment options, and treatment recommendations. ⋯ An unmet need may still exist with these options, however, leaving a role for neuromodulation for the treatment of intractable cases. A pain management algorithm for iterative interventions including stimulation of the dorsal root ganglion (DRG) is described. It is expected that cross-disciplinary awareness of surgeons for nonsurgical pain management options in the treatment of chronic neuropathic postherniorrhaphy pain will contribute to better clinical outcomes.
