The CDC reported in 2017 that the largest increments in probability of continued use were observed after days 5 and 31 on opioid therapy. This study demonstrates the correlation between a system-wide pain management and opioid stewardship effort with reductions in discharge prescriptions for elective surgical patients. ⋯ A system-wide, multipronged pain management and opioid reduction program significantly reduced opioid discharge prescriptions written for more than 5 days. This approach can serve as a model for other healthcare systems attempting to reduce opioid prescribing and combat the opioid crisis in the US.

Prescription opioid related deaths have increased dramatically over the past 17 years. Although emergency physicians (EPs) have not been the primary force behind this rise, previous literature have suggested that EPs could improve their opioid prescribing practices. We designed this study to evaluate the trend in emergency department (ED) opioid prescriptions over time during the US opioid epidemic. ⋯ ED physicians are prescribing less opiates, while increasing the amount of non-narcotic analgesic prescriptions. This may be in response to the literature suggesting that prescription opioids play a large role in the opioids crisis. This decrease in opioid prescriptions did not increase the need for repeat ED visits.

Binding and signaling kinetics have previously proven important in validation of biased agonism at GPCRs. Here we provide a comprehensive kinetic pharmacological comparison of clinically relevant μ-opioid receptor agonists, including the novel biased agonist oliceridine (TRV130) which is in clinical trial for pain management. We demonstrate that the bias profile observed for the selected agonists is not time-dependent and that agonists with dramatic differences in their binding kinetic properties can display the same degree of bias. ⋯ GRK2 and GRK5 overexpression greatly increased μ-opioid receptor internalization induced by morphine, but only had modest effects on buprenorphine and oliceridine-induced internalization. Overall, our data reveal that the clinically available drug buprenorphine displays a similar pharmacological bias profile in vitro compared to the clinical candidate drug oliceridine and that this bias is independent of binding kinetics suggesting a mechanism driven by receptor-conformations.

Randomized Controlled TrialPostoperative analgesic efficacy of perioperative intravenous lidocaine infusion in patients undergoing septorhinoplasty: a prospective, randomized, double-blind study.
Intravenous lidocaine infusion has been used for postoperative analgesia in many surgical procedures in recent years. The aim of this randomized, double-blind study was to investigate the postoperative analgesic efficacy of perioperative intravenous lidocaine infusion in patients undergoing septorhinoplasty surgery. ⋯ We recommended the use of intravenous lidocaine infusion for intraoperatively and first postoperative hours in septorhinoplasty surgery as it reduces pain scores and the need for additional opioid use.
