Because of its side effects, a morphine replacement has been searched for in the field of postoperative analgesia. Hydromorphone is a derivative of morphine with no active metabolites. ⋯ There was no significant statistical difference in postoperative analgesic effect between hydromorphone and morphine, as well as side effects, including severe sedation, nausea, and vomiting at 24 hours postoperative. However, the incidence of pruritus was lower in the hydromorphone group at 24 hours postoperative.

Intravenous Versus Peribulbar Dexmedetomidine as an Adjunct to Local Anesthetics in Strabismus Surgery: A Randomized, Double-blinded Clinical Trial.
Dexmedetomidine has not been adequately studied as an adjuvant to peribulbar anesthesia in strabismus surgery. ⋯ Peribulbar dexmedetomidine outperforms intravenous dexmedetomidine in terms of postoperative analgesia and motor block duration when used as an adjunct to peribulbar anesthesia for strabismus surgery. However, the intravenous group had significantly shorter surgical times.

Peripheral nerve stimulation (PNS) has been used for over 50 years to treat chronic pain by delivering electrical pulses through small electrodes placed near targeted peripheral nerves those outside the brain and spinal cord. Early PNS systems often required invasive neurosurgical procedures. However, since 2015, the Food and Drug Administration (FDA) approved percutaneously implanted PNS leads and neurostimulators offering a much less invasive, non-opioid option for managing recalcitrant chronic pain. The following FDA-cleared PNS systems are commercially available in the United States for the management of chronic, intractable pain:• Freedom® Peripheral Nerve Stimulator (PNS) System (Curonix LLC, 2017) • StimRouter® Neuromodulation System (Bioness, now Bioventus, 2015)• SPRINT® PNS System (SPR® Therapeutics, Inc., 2016) • Nalu™ Neurostimulation System (Nalu Medical Inc., 2019)• ReActiv8® Implantable Neurostimulation System (Mainstay Medical Limited, 2020) The American Society of Interventional Pain Physicians (ASIPP) has published evidence-based consensus guidelines for the application of PNS systems in managing chronic pain. ⋯ These evidence-based guidelines support the use of implantable peripheral nerve stimulation leads and neurostimulators in patients with moderate to severe chronic pain refractory to two or more conservative treatments. These guidelines aim to optimize patient outcomes and promote health equity through the integration of PNS technology in clinical practice.

Fibromyalgia is a complex condition that has long puzzled the medical community. Hypotheses to explain the chronic widespread pain associated with the disease have evolved significantly over the years. However, research efforts to identify disease-specific biomarkers and develop effective treatments have been largely unsuccessful. ⋯ Fibromyalgia is likely the result of multiple causative factors, genetic and environmental. To date, no clear, reliable etiological biomarker for fibromyalgia has been identified. The considerable variability among patients suggests the presence of multiple disease subtypes with different pathophysiological mechanisms. Effective treatment therefore requires a multimodal, multidisciplinary approach that targets each individual patient's pathophysiological features. The proposed treatment paradigm attempts to address multiple factors that have been implicated more recently in the development and maintenance of fibromyalgia, such as micro-inflammation, metabolic syndrome, and gut dysbiosis.

Randomized Controlled Trial
Dose Equivalence of Remimazolam and Propofol for Loss of Consciousness in Pediatric Patients: A Randomized Clinical Trial.
Remimazolam and propofol can be used interchangeably for general anesthesia. However, no dosing recommendations exist for the intravenous bolus administration of remimazolam during general anesthesia induction in pediatric patients. Determining the appropriate dose for anesthesia induction in pediatric patients is crucial for safe and effective surgical procedures. ⋯ Remimazolam demonstrates significantly higher sedative efficacy for pediatric patients than does propofol. An induction dose of 0.34 mg/kg-1 remimazolam could be recommended for general anesthesia induction, considering the safety and effectiveness of a 2 mg/kg-1 dose of propofol.
