Neonates, infants and children are often exposed to pain from invasive procedures during intensive care and during the post-operative period. Opioid anesthesia and post-operative opioid analgesia have been used in infants and result in clinical benefits. The objectives of this study were to verify the effect of repeated 5 microg morphine administration (subcutaneous), once a day for 7 days in 8-day-old rats, at P8 until P14. To verify the long-term effect of morphine, the animals were submitted to a second exposure of 5mg/kg (intraperitoneal) of morphine at P80 until P86. Animals that received morphine for 7 days, at P14 did not develop tolerance, however at P80, rats demonstrated greater morphine analgesia. At P86, after 7 days of morphine administration, animals showed classical tolerance. These findings may have important implications for the human neonate, suggesting a possible explanation for the differences in the requirements of morphine observed in the youngest patients.

Introduction: Droperidol is a dopamine-2 receptor antagonist in the class of butyrophenone antipsychotics with antiemetic, sedative, analgesic, and anxiolytic properties. In the postoperative setting, droperidol provides an opioid sparing effect and decreases nausea/vomiting. Another butyrophenone antipsychotic, haloperidol, has been shown to reduce morphine milliequivalents (MME) administered when used for abdominal pain in the emergency department (ED).

Background: As the opioid epidemic continues, a better understanding of the use of opioids in surgery is needed. We examined whether intraoperative opioid administration was associated with greater postoperative opioid use prior to discharge in opioid-naïve patients undergoing thoracic surgery. Further, we sought to determine predictors of higher intra- and postoperative opioid use including demographic and patient factors and hospital.

Background: Opioid crisis is a national issue with significant economic burden and marked increase in opioid-related deaths, particularly following surgical procedures. Reducing opioid requirements while maintaining effective analgesia is critically challenging, perioperatively. Multimodal drug regimens and guided regional anesthesia (RA) have been adopted to address this issue.

Background: Postoperative pain remains a significant problem in patients undergoing donor nephrectomy despite reduced tissue trauma following laparoscopic living donor nephrectomy (LLDN). Inadequately treated pain leads to physiological and psychological consequences, including chronic neuropathic pain.
Materials And Methods: This randomized controlled double-blinded trial was conducted in sixty-nine (n = 69) participants who underwent LLDN under general anesthesia.
Use of Causal Framework to Evaluate Effect of Abuse Deterrent Properties of Extended-Release Oxycodone on Tampering in a Real-World Settings.

Purpose: To assess whether exposure to an extended-release (ER) oxycodone with abuse deterrent properties (ADF) reduced tampering of oxycodone in a real-world, postmarket setting to address the thinking behind Category 4 labeling by the FDA.
Methods: Data from an observational cross-sectional study of the general adult population (2022) was used under a causal framework to estimate the confounding-adjusted odds of tampering oxycodone after exposure to two types of ADF ER oxycodone. The tampering behaviors of those who used only single entity immediate-release (SE-IR) oxycodone was used as a comparison.
