Randomized Controlled Trial
Intrathecal Dexmedetomidine, Ketamine, and their Combination Added to Bupivacaine for Postoperative Analgesia in Major Abdominal Cancer Surgery.
Intrathecal ketamine has been studied extensively in animals, but rarely in humans. Intrathecal dexmedetomidine prolongs the duration of spinal anesthesia. ⋯ In conclusion, the combination of intrathecal dexmedetomidine and ketamine provided superior postoperative analgesia, prolonged the time to first request of rescue analgesia, and reduced the total consumption of PCA morphine, without serious side effects compared to either drug alone.

Randomized Controlled Trial
A New Look on Adding Dexamethasone as an Adjuvant to Caudal Bupivacaine; Efficacy on Postoperative Pain and Vomiting in Pediatric Patients.
Controlling postoperative pain and vomiting in children remains a great challenge. ⋯ Analgesic and antiemetic effects of dexamethasone as an adjunct to caudal block with bupivacaine (0.25%) 0.5 mL/kg is similar whether administered intravenously 0.5 mg/kg or caudally 0.1 mg/kg.

Randomized Controlled Trial
A Randomized Trial Comparing the Safety and Efficacy of Intravenous Ibuprofen versus Ibuprofen and Acetaminophen in Knee or Hip Arthroplasty.
All surgical procedures are associated with a degree of pain. The experience of uncontrolled post-operative pain can have significant implications on health care costs. Recent studies have demonstrated that intravenous (IV) ibuprofen is an effective, safe, well-tolerated analgesic when administered for both abdominal hysterectomy and orthopedic surgery. The use of ibuprofen leads to a reduction in pain severity at rest and with movement and also decreases narcotic consumption. IV acetaminophen has also been shown to be effective in alleviating pain for surgical procedures. Given the established safety and efficacy of IV ibuprofen and IV acetaminophen for perioperative pain, we were interested in determining if any potential synergies are afforded by the simultaneous administration of both medications in orthopedic surgery patients. ⋯ IV ibuprofen combined with IV acetaminophen demonstrated additional benefit in terms of improved pain scores on post-operative day 3 only, fewer potential adverse events related to opioid use, and decreased use of opioids when compared to IV ibuprofen alone.

Offset analgesia (OA) is an increasingly described phenomenon to measure endogenous pain inhibition, in which a greater decrease in pain intensity is experienced than would be predicted by the decrease in painful stimulation. The temporal filtering in this OA phenomenon differs from the spatial filtering in the commonly described conditioned pain modulation (CPM). Yet, the knowledge on the efficacy of OA in chronic pain patients is scarce, compared to CPM efficacy. ⋯ This systematic review displays OA as a temporal filtering mechanisms that is more brain-derived compared to the spatial assessment method CPM. There is strong evidence for reduced OA in neuropathic patients, however, evidence regarding OA in (sub)acute and central sensitization patients, and the influence of personal factors on OA is currently scarce and needs further investigation.

Auto-Targeted Neurostimulation Is Not Superior to Placebo in Chronic Low Back Pain: A Fourfold Blind Randomized Clinical Trial.
Myofascial trigger points (MTrPs) are common in people with musculoskeletal pain and may play a role in chronic nonspecific low back pain (CLBP). One of the potential treatments of MTrPs is the Nervomatrix Soleve® auto-targeted neurostimulation device, providing targeted transcutaneous electrical nerve stimulation (TENS) to MTrPs in the lower back muscles. To date, no controlled studies have evaluated the effectiveness of this device for the pain management of this population. ⋯ Treatment of MTrPs with the Nervomatrix Soleve® auto-targeted neurostimulation device in patients with CLBP does not result in a better outcome than placebo-treatment in terms of pain, pain behavior, functioning, central sensitization, pain catastrophizing, and health beliefs.
