Observational Study
Use of injections for chronic pain from 2010 to 2019 in Ontario, Canada.
The management of chronic pain often involves interventional procedures such as injections. Nevertheless, there have been concerns raised regarding the frequency with which these injections are being performed. We conducted a descriptive study to examine trends in the use of pain injections over a ten-year time period in Ontario, Canada. ⋯ This descriptive study revealed a rapid increase in the frequency of pain injections performed in Ontario from 2010 to 2019. Given the associated costs and potential risks, this warrants further investigation to ensure that these interventions are being administered appropriately.

Randomized Controlled Trial
Ultrasound-guided selective peripheral nerve block compared with the sub-dissociative dose of ketamine for analgesia in patients with extremity injuries: An open-label randomized clinical trial.
To compare the analgesic efficacy of ultrasound-guided selective peripheral nerve block (PNB) and sub-dissociative dose ketamine (SDK) for management of acute pain in patients with extremity injuries presenting to the emergency department (ED). ⋯ The study provides evidence that ultrasound-guided PNB is superior to SDK in terms of its analgesic efficacy in the management of acute pain due to extremity injuries and is associated with higher patient satisfaction. The need for rescue analgesia was significantly less in the PNB group. SDK was associated with a high incidence of dizziness and nausea.

Meta AnalysisThe effectiveness of scalp nerve block on hemodynamic response in craniotomy: a systematic review and meta-analysis of randomized trials.
Strategies that blunt noxious stimuli and stabilize hemodynamics may reduce perioperative cardiovascular complications and enhance recovery after craniotomy. ⋯ SNB alleviated the craniotomy-associated hemodynamic response. SNB may be superior to scalp infiltration in maintaining hemodynamic stability during pin insertion. However, high-quality trials are still needed to provide more conclusive evidence.
