Prescription of modified-release opioids for acute postoperative pain is widespread despite evidence to show their use may be associated with an increased risk of adverse effects. This systematic review and meta-analysis aimed to examine the available evidence on the safety and efficacy of modified-release, compared with immediate-release, oral opioids for postoperative pain in adults. We searched five electronic databases from 1 January 2003 to 1 January 2023. ⋯ Our narrative synthesis concluded that modified-release opioids showed no superiority over immediate-release opioids for analgesic consumption, length of hospital stay, hospital readmissions or physical function after surgery. One study showed that modified-release opioid use is associated with higher rates of persistent postoperative opioid use compared with immediate-release opioid use. None of the included studies reported on psychological function, costs or quality of life.

ReviewPharmacokinetic pharmacodynamic modeling of analgesics and sedatives in children.
Pharmacokinetic pharmacodynamic modeling is an important tool which uses statistical methodology to provide a better understanding of the relationship between concentration and effect of drugs such as analgesics and sedatives. Pharmacokinetic pharmacodynamic models also describe between-subject variability that allows identification of subgroups and dose adjustment for optimal pain management in individual patients. This approach is particularly useful in the pediatric population, where most drugs have received limited evaluation and dosing is extrapolated from adult practice. ⋯ An adequate assessment of analgesic and sedative effect using pain scales or brain activity measures is essential to build reliable pharmacokinetic pharmacodynamic models. This is often challenging in children due to the multidimensional nature of pain and the limited sensitivity and specificity of some measurement tools. This review provides a summary of the pharmacokinetic and pharmacodynamic methodology used to describe the dose-concentration-effect relationship of analgesics and sedation in children, with a focus on the different pharmacodynamic endpoints and the challenges of pharmacodynamic modeling.

Low-Impact Laparoscopy vs Conventional Laparoscopy for Appendectomy: A Prospective Randomized Trial.
Low-impact laparoscopy (LIL), combining low-pressure insufflation and microlaparoscopy, is a surgical technique that is still not widely used and that has never been evaluated for the management of acute appendicitis. The aim of this study is to assess the feasibility of an LIL protocol, to compare postoperative pain, average length of stay, and in-hospital use of analgesics by patients who underwent appendectomy according to a conventional laparoscopy or an LIL protocol. ⋯ In uncomplicated acute appendicitis, the LIL protocol could reduce postoperative pain and average length of stay compared to conventional laparoscopic appendectomy.

Thyroid and parathyroid operations are among the most commonly performed surgeries in the world; however, there remains a paucity of prospective clinical trials evaluating the efficacy of opioid-sparing protocols after surgery. ⋯ An opioid-sparing treatment algorithm based on the use of acetaminophen/ibuprofen may offer a safe and effective treatment algorithm compared to a primary opioid-focused treatment pathway. Randomized adequately powered studies are needed to confirm these findings.

Low back pain (LBP) is a complex condition that is widespread among older Black adults. Nonpharmacologic interventions are recommended as first-line therapy, but their use in practice is limited, possibly due to misunderstanding of their analgesic characteristics. ⋯ Listening to preferred music for 20 minutes twice a day is a feasible and acceptable intervention that can considerably reduce pain in older Black adults with LBP.
