ReviewPeripherally Acting μ-Opioid Receptor Antagonists in the Management of Postoperative Ileus: a Clinical Review.
Postoperative ileus (POI) and constipation are common secondary effects of opioids and carry significant clinical and economic impacts. μ-Opioid receptors mediate opioid analgesia in the central nervous system (CNS) and gastrointestinal-related effects in the periphery. Peripherally acting μ-opioid receptor antagonists (PAMORAs) block the peripheral effects of opioids in the gastrointestinal tract, while maintaining opioid analgesia in the CNS. ⋯ This review will discuss recent clinical trials evaluating the safety and efficacy of PAMORAs, with a focus on alvimopan (Entereg®) and methylnaltrexone (Relistor®) in patients with POI or postoperative OIC. We will characterize potential factors that may have impacted the efficacy observed in phase 3 trials and discuss future directions for the management and treatment of POI.

Editorial Commentary: Neuraxial Anesthesia Improves Pain After Hip Arthroscopy but Risks Ambulatory Discharge Delay.
Hip arthroscopy continues to be one of the fastest-growing orthopaedic procedures nationally, and pain control following these procedures can be challenging. As regional anesthesia techniques for this population have shown to have limited benefits, pain management for hip arthroscopy focused on multimodal analgesia and preventive analgesia, interventions that reduce postoperative hyperalgesia. The use of neuraxial anesthesia such as spinal and epidural anesthesia, established preventive analgesic anesthetic techniques, has demonstrated to improve postoperative pain in orthopaedic surgery when compared with general anesthesia. This promising finding highlights that despite potential disadvantages of neuraxial anesthesia, such as a small risk for complications or delayed resolution of the neuraxial block that could delay discharge, neuraxial anesthesia could be a suitable anesthetic technique for ambulatory orthopaedic surgery.

Randomized Controlled TrialRandomized trial of methadone treatment of arrestees: 24-month post-release outcomes.
We report on the 24-month post-release outcomes of arrestees with opioid use disorder (OUD) enrolled in a randomized trial comparing three treatment approaches initiated in jail. ⋯ ClinicalTrials.gov: NCT02334215.

Comparative StudyObservation of Complement Protein Gene Expression Before and After Surgery in Opioid-Consuming and Opioid-Naive Patients.
Opioids may influence inflammation. We compared genes associated with pain and inflammation in patients who consumed opioids (3-120 mg of oral morphine equivalents per day) with those who did not for differential expression. ⋯ We report that the expression of a complement inhibitor, complement 4 binding protein A, was reduced, and the expression of a complement activator, complement factor D, was increased in opioid-consuming patients. We conclude that opioid consumption may influence expression of complement activators and inhibitors.

Variability exists in opioid prescribing practices among surgeons, frequently resulting in the prescription of excessive opioids. This study evaluated the ability of a single educational intervention targeted toward general surgery residents to reduce the quantity of postoperative opioids prescribed. ⋯ Following this targeted intervention, patients were discharged with fewer OME and more nonopioid analgesics, even as refill requests decreased. Educating residents on opioid prescription guidelines and multimodal therapy is effective and should be part of the annual didactic curriculum.
