Randomized Controlled Trial Comparative Study
Analgo-Sedative Effects of Oral or Nebulized Ketamine in Preschoolers Undergoing Elective Surgery: A Comparative, Randomized, Double-Blind Study.
Premedication in children with ketamine is useful to produce mild sedation, decrease anxiety, help the child separation from parents, and provide postoperative pain relief with no or little adverse effects. ⋯ Nebulized ketamine, oral ketamine, preschooler, elective surgery.

Randomized Controlled Trial Comparative Study
Comparison of Epidural Pressure Decrease Pattern According to Different Lumbar Epidural Approaches.
During lumbar epidural injection (LEI) using a midline approach, we might encounter failure of identifying the epidural space owing to an equivocal or absent loss of resistance (LOR) sensation. The reason for such absence of LOR sensation has been suggested as paucity of midline ligamentum flavum, paravertebral muscle, and cyst in the interspinous ligament of the lumbar spine. Despite its low specificity, LOR is the most commonly used method to identify the epidural space. ⋯ Epidural, paramedian, midline, pressure decrease.

Comparisons of Monopolar Lesion Volumes with Hypertonic Saline Solution in Radiofrequency Ablation: A Randomized, Double-Blind, Ex Vivo Study.
Chronic degeneration of the zygapophyseal joints in the cervical or lumbar spine are common causes of axial back pain. Radiofrequency (RF) ablation is a treatment modality in the denervation of facet joint-related pain. Although multiple factors have been theorized to contribute to the size of the optimal RF lesion, the addition of hypertonic saline solution has been posited to create larger RF lesion sizes. ⋯ Radiofrequency, ablation, lesion shape, lesion size, monopolar RF, hypertonic saline solution.

Acute pain management in patients on buprenorphine opioid agonist therapy (BOAT) can be challenging. It is unclear whether BOAT should be continued or interrupted for optimization of postoperative pain control. ⋯ Opioid use disorder, opiate substitution treatment, buprenorphine, buprenorphine-naloxone, buprenorphine opioid agonist therapy, postoperative pain, acute pain, multimodal analgesia.

Early Treatment with Temporary Spinal Cord Stimulation Effectively Prevents Development of Postherpetic Neuralgia.
Some 7.7% of the Chinese population suffer from herpes zoster each year, with 29.8% proceeding on to develop postherpetic neuralgia (PHN). This amounts to over 32 million people per year. PHN is preceded by 2 phases of pain: acute herpetic neuralgia (AHN), and subacute herpetic neuralgia (SHN). Considering the large individual and economic burden, preventing the transition of AHN/SHN to PHN is crucial. However, to date this has been difficult. ⋯ Herpes zoster, zoster-related pain, postherpetic neuralgia, temporary spinal cord stimulation.
