Background: Intra-operative use of opioid analgesics might have an impact on cancer recurrence and survival after surgery. The objective of this study was to investigate the association between the intra-operative fentanyl equivalents and survival outcomes in patients with primary liver cancer after receiving hepatectomy.
Methods: This was a retrospective single-center cohort study, and clinical data of 700 patients with primary liver cancer who underwent hepatectomy in Harbin Medical University Cancer Hospital from September 2013 to August 2018 were reviewed. After propensity matching, 376 patients were included. Patients were divided into high-dose and low-dose groups according to the median intra-operative fentanyl equivalents (1.500 mg). Kaplan Meier curve and Cox proportional hazards regression model were used.
Results: Results of univariable analysis showed there were no significant differences in recurrence-free survival (RFS) (p = 0.136) and overall survival (OS) (p = 0.444) between high-dose fentanyl equivalents and low-dose fentanyl equivalents group. The multivariable Cox regression analysis found that the dose of intra-operative fentanyl equivalents was not associated with RFS (HR: 1.119, 95%CI: 0.851-1.472, p = 0.422) or OS (HR: 0.939, 95%CI: 0.668-1.319, p = 0.715).
Conclusions: The amounts of intra-operative fentanyl equivalents had no impact on recurrence-free or overall survival in patients with primary liver cancer after curative hepatectomy.

Buprenorphine has superior safety in opioid use disorder compared with alternatives due to its action as a partial opioid agonist, which limits its ability to cause respiratory depression. There is a risk of precipitated opioid withdrawal after buprenorphine exposure in someone using full opioid agonists. Buprenorphine induction strategies that avoid precipitated withdrawal remain a crucial component for starting buprenorphine in individuals actively using opioids.

Background: Fentanyl use leads to increased opioid tolerance in people with opioid use disorder, complicating management of opioid withdrawal syndrome. While accepted as gold standard, methadone and buprenorphine may be insufficient to treat acute opioid withdrawal. Short-acting full agonist opioids (SAFAO) may improve treatment in the acute care setting.

Background: Posterior spinal fusion (PSF) surgery for correction of idiopathic scoliosis is associated with chronic postsurgical pain (CPSP). In this multicenter study, we describe perioperative multimodal analgesic (MMA) management and characterize postoperative pain, disability, and quality of life over 12 months after PSF in adolescents and young adults.
Methods: Subjects (8-25 years) undergoing PSF were recruited at 6 sites in the United States between 2016 and 2023.

Background: Poorly controlled acute breast surgery postoperative pain is associated with delayed recovery, increased morbidity, impaired quality of life, and prolonged opioid use during and after hospitalization. Recently, ultrasound-guided pectoralis nerve (PECS) I block and serratus anterior plane (SAP) block, together or individually, have emerged as a potential method to relieve pain, decrease opioid requirements, and improve patient outcomes.
Objective: The aim of this study was to assess if the addition of a PECS I/SAP block in patients undergoing bilateral mastectomies provides more effective perioperative analgesia compared to standard analgesia.
