Nociception level index: do intra-operative values allow the prediction of acute postoperative pain?
Nociception Level Index (NOL) guided analgesia has previously been found to correlate with noxious stimuli during surgery. It was aim of this study to investigate the relationship between intra-operative NOL and acute postoperative pain. After IRB approval, 80 patients scheduled for non-emergency surgery were enrolled. ⋯ The NOL reaction to skin incision, but not NOL during surgery appears to allow the exclusion and, to a lesser degree the prediction of moderate-severe pain in PACU. The results may also strengthen the manufacturers recommendation of an intraoperative NOL range of 10-25. Australian New Zealand Clinical Trials Registry: ACTRN12619001596190.

Anesthesiologists have long used multimodal analgesia for effective pain control. Opioid-sparing anesthetics are gaining popularity among practitioners in light of increasing concerns for both immediate opioid side effects and the long-term opioid misuse among susceptible patients. Currently, there is a critical gap in knowledge regarding outcomes after an opioid-free anesthetic (OFA) during general anesthesia. We hypothesized that an opioid-free general anesthetic will not be inferior to a traditional opioid anesthetic (OA) as measured by the perioperative outcomes of postanesthesia care unit (PACU) duration, 12-hour postoperative summed pain intensity (SPI12) scores, total morphine equivalent doses (MEDs) utilized in the 12-hour postoperative inpatient (MED12) and total MEDs utilized in the 90-day outpatient periods (MED90). ⋯ To our knowledge, this is the first matched cohort study directly comparing an OFA with a traditional anesthetic for general anesthesia in a wide range of surgical and clinical scenarios. There was no significant difference in SPI12 between the OFA group and OA group, suggesting that patients' subjective pain was similar immediately after surgery whether or not they received intraoperative opioids. Concurrently, no "catch-up" effect was observed as the PACU duration; MED12 and MED90 were not different between the OFA and OA groups. However, there were many covariates identified in this study because of the small sample size or each group. Additional research is needed to explore if these findings can be extrapolated to a larger more heterogeneous population. Our preliminary work suggests that eliminating patient exposure to opioids in the intraoperative period does not have a deleterious effect on perioperative patient outcomes.

Randomized Controlled Trial
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.

Review Meta Analysis
Efficacy and safety of rhomboid intercostal block for analgesia in breast surgery and thoracoscopic surgery: a meta-analysis.
Rhomboid intercostal block (RIB) is a new regional anesthesia technique that provides postoperative analgesia for breast surgery and thoracoscopic surgery. The published papers are not yet fully integrated and do not adequately address the impact and safety of the RIB on postoperative pain. ⋯ This review shows that RIB was more effective in controlling acute pain after breast surgery and thoracoscopic surgery than general analgesia. And it is a trend that RIB may be a kind of effective and safe nerve bock technology and it requires further studies.
