Hydrocodone (HYD) is one of the most widely prescribed opioid analgesic drugs. Several neurotransmitters are involved in opioids relapse. Among these neurotransmitters, glutamate is suggested to be involved in opioid dependence and relapse. ⋯ HYD exposure downregulated xCT expression in the nucleus accumbens and hippocampus, but no effects were observed in the dorsomedial prefrontal cortex and amygdala. Importantly, CEF treatment attenuated the reinstatement effect of HYD and normalized xCT expression in the affected brain regions. These findings demonstrate that the attenuating effect of HYD reinstatement with CEF might be mediated through xCT.

Randomized Controlled Trial
Does fentanyl or remifentanil provide better postoperative recovery after laparoscopic surgery? a randomized controlled trial.
Fentanyl and remifentanil are widely used opioids in surgery, but it has not been evaluated whether the choice of opioids during surgery affects the patients' postoperative quality of recovery. Accordingly, we aim to compare postoperative recovery of fentanyl-based anesthesia with remifentanil-based anesthesia after laparoscopic surgery using the QoR 40 questionnaire (QoR-40). ⋯ Although the global QoR is higher in the fentanyl group by 20 points compared with remifentanil group, no significant differences revealed between the groups. Further studies with large numbers of subjects of the same gender are needed.

ReviewComplexities of Perioperative Pain Management in Orthopedic Trauma.
This review discusses both obvious and hidden barriers in trauma patient access to pain management specialists and provides some suggestions focusing on outcome optimization in the perioperative period. ⋯ Orthopedic trauma surgeons strive to provide patients the best possible perioperative pain management, while balancing against potential risks of opioid abuse and addiction. Surgeons often find they are ill-prepared to effectively manage postoperative pain in patients returning several months following trauma surgery, many times still dependent on opioids for pain control. Some individuals from this trauma patient population may also require the care of pain management specialists and/or consultation with drug addiction specialists. As the US opioid epidemic continues to worsen, orthopedic trauma surgeons can find it difficult to obtain access to pain management specialists for those patients requiring complex pain medication management and substance abuse counseling. The current state of perioperative pain management for orthopedic trauma patients remains troubling due to reliance on only opioid analgesics, society-associated risks of opioid medication addiction, an "underground" prescription drug marketplace, and an uncertain legal atmosphere related to opioid pain medication management that can deter pain management physicians from accepting narcotic-addicted patients and discourage future physicians from pursuing advanced training in the specialty of pain management. Additionally, barriers continue to exist among Medicaid patients that deter this patient population from access to pain medicine subspecialty care, diminishing medication management reimbursement rates make it increasingly difficult for trauma patients to receive proper opioid analgesic pain medication management, and a lack of proper opioid analgesic medication management training among PCPs and orthopedic trauma surgeons further contributes to an environment ill-prepared to provide effective perioperative pain management for orthopedic trauma patients.
