Peripheral nerve stimulation (PNS) has been increasingly used to manage acute and chronic pain. However, the level of clinical evidence to support its use is not clear. ⋯ The findings of this systematic review suggest that PNS may be effective in managing chronic headaches, postamputation pain, chronic pelvic pain, and chronic low back and lower extremity pain, with variable levels of evidence in favor of this technique.

Ketamine is a noncompetitive N-methyl-D-aspartate/glutamate receptor complex antagonist that decreases pain by diminishing central sensitization and hyperalgesia. When administered via i.v. (push-dose, short infusion, or continuous infusion) or intranasal routes, ketamine has shown to be effective in patients with acute traumatic pain. However, when i.v. access is not attainable or readily available, the inhalation route of ketamine administration via breath-actuated nebulizer (BAN) provides a noninvasive and titratable method of analgesic delivery. The use of nebulized ketamine has been studied in areas of postoperative management of sore throat and acute traumatic musculoskeletal and abdominal pain. To our knowledge, this is the first case series describing the use of nebulized ketamine for analgesia and orthopedic reduction. ⋯ We describe 4 patients who presented to the emergency department with acute traumatic painful conditions (one patellar dislocation, one shoulder dislocation, and two forearm fractures) and received nebulized ketamine for management of their pain. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Administration of nebulized ketamine via BAN can be used as analgesic control for musculoskeletal trauma, as it can be administrated to patients with difficult i.v. access, has a rapid onset of analgesic effects with minimal side effects, and remains opioid-sparing.

Patients with low back pain frequently undergo a variety of diagnostic and therapeutic interventions, but some of these have uncertain effectiveness. This highlights the importance of the association of healthcare services and therapeutic measures relating to disability. ⋯ Occurrence of the combined of consultations and medication use was correlated with higher chance of severe disability among these elderly people with nonspecific low back pain. This suggested that overuse and "crowding-in" effects were present in medical services for elderly people.

Low-Dose Ketamine Infusion as Adjuvant Therapy during an Acute Pain Crisis in Pediatric Patients.
Recent studies in pediatric patients have suggested that ketamine, an N-methyl-D-aspartate receptor (NMDA) antagonist, given at sub-anesthetic doses can effectively decrease pain scores, provide analgesic effects, and in some cases, reduce opioid requirements. Our study aims to assess impact of low-dose ketamine on reducing pain scores and total opioid requirements during an acute pain crisis in pediatric patients. From November 2016 to December 2018, eight patients between the ages of 2 and 17 years admitted to the pediatric intensive care unit (PICU) were treated with LDK infusions to manage severe, opioid-refractory, acute pain crises. ⋯ Hallucination was reported in one patient which resolved upon dose reduction. LDK infusion could be considered as an adjuvant therapy to optimize pain control in pediatric patients experiencing acute pain crises. Further investigation with a larger patient population is warranted to establish the effects of LDK on pain improvement and reducing total opioid requirements.

Risk factors associated with higher pain levels among pediatric burn patients: a retrospective cohort study.
There is an absence of evidence regarding predictors of moderate to severe pain in children undergoing acute burn treatment. This investigation aimed to determine if relationships existed between patient and clinical characteristics, and pain at first dressing change for children with acute burn injuries. ⋯ It is recommended that patients presenting with one or more of the aforementioned factors are identified before their first dressing change, so additional pain control methods can be implemented.
