Randomized Controlled Trial
Brain-based measures of nociception during general anesthesia with remifentanil: A randomized controlled trial.
Catheter radiofrequency (RF) ablation for cardiac arrhythmias is a painful procedure. Prior work using functional near-infrared spectroscopy (fNIRS) in patients under general anesthesia has indicated that ablation results in activity in pain-related cortical regions, presumably due to inadequate blockade of afferent nociceptors originating within the cardiac system. Having an objective brain-based measure for nociception and analgesia may in the future allow for enhanced analgesic control during surgical procedures. Hence, the primary aim of this study is to demonstrate that the administration of remifentanil, an opioid widely used during surgery, can attenuate the fNIRS cortical responses to cardiac ablation. ⋯ We observed cortical activity related to nociception during cardiac ablation under general anesthesia with remifentanil. It highlights the potential of fNIRS to provide an objective pain measure in unconscious patients, where cortical-based measures may be more accurate than current evaluation methods. Future research may expand on this application to produce a real-time indication of pain that will aid clinicians in providing immediate and adequate pain treatment.

Tapering Opioid Prescription Program for High-Risk Trauma Patients: A Pilot Randomized Controlled Trial.
Chronic opioid use has been documented in up to 20% of patients with traumatic injuries. Hence, we developed the Tapering Opioids Prescription Program for high-risk Trauma (TOPP-Trauma) patients. ⋯ Some challenges need to be addressed before testing TOPP-Trauma. These include creating strategies to decrease attrition, offering the program throughout the care continuum to higher risk patients, and evaluating the impacts of reduced opioid use.

Shoulder tip pain after cesarean section: General versus spinal anesthesia.
Shoulder tip pain is a common but overlooked complication during the postoperative cesarean section. In this study, we aimed to investigate the relationship between the anesthesia method and the incidence of shoulder tip pain. ⋯ This study shows that the frequency and severity of shoulder pain are higher in women who have had cesarean section under spinal anesthesia, compared to those who had received general anesthesia.

Evaluation of Analgesic Efficacy and Opioid-sparing Effect of Duloxetine After Arthroscopic Rotator Cuff Repair: A Randomized Clinical Trial.
This study aimed to evaluate the analgesic efficacy and opioid-sparing effect of duloxetine in adults having arthroscopic rotator cuff repair, as well as its clinical safety. ⋯ For patients undergoing arthroscopic rotator cuff repairs, duloxetine resulted in a significant reduction in pain within postoperative 2 days, but the reduction was not clinically meaningful. Duloxetine did not decrease the opioid consumption within postoperative 2 days and did not increase the risk of bleeding within postoperative 2 days. The incidence of nausea and vomiting in the duloxetine group was significantly greater than that in the placebo group.

Randomized Controlled Trial
Impact of variability in baseline pain on the placebo response in randomized, placebo-controlled, crossover trials in peripheral neuropathic pain.
Large placebo responses often negatively affect randomized controlled trials within the pain area. Understanding different possible factors that influence the placebo response is therefore important. In this retrospective analysis, we hypothesized that a large variability in baseline pain score would predict a greater placebo response and analyzed the impact of the coefficient of variation, SD, and difference between the highest and lowest numeric rating scale (NRS) score at baseline on the placebo response. ⋯ Placebo response in one trial did not predict placebo response in another trial. A large placebo response was not associated with a large treatment response. In conclusion, in this retrospective data analysis, there was no impact of baseline pain variability on the placebo response in controlled clinical trials with a crossover design in patients with peripheral neuropathic pain.
