To evaluate the effect of intraoperative intravenous methadone within a standardized enhanced recovery after cardiac surgery pathway on the perioperative corrected QT interval (QTc). Retrospective cohort study. Cardiac surgical patients from a tertiary academic medical institution. Eligible 1,040 adult patients undergoing elective cardiac surgery from July 2020 through July 2023 using validated institutional electronic medical record data INTERVENTIONS: Patients were administered intravenous methadone (0.1 mg/kg) or received analgesics other than intravenous methadone as part of an enhanced recovery after cardiac surgery pathway. The primary outcomes were change in QTc and the percent QTc change between preoperative QTc and postoperative QTc upon intensive care unit admission. Secondary outcomes include postoperative ventricular arrhythmias, postoperative atrial fibrillation, intensive care unit length of stay, 30-day mortality, 1-year mortality, and mortality days from surgery. Out of a total of 1,040 patients, 423 received intraoperative methadone and 617 did not receive methadone. Methadone QTc mixed models demonstrated that QTc is prolonged immediately postoperatively and normalized 24 hours after surgery in both methadone and nonmethadone groups. There were no significant differences in baseline QTc, immediate postoperative QTc, changes in QTc, or percent change in QTc between the methadone and nonmethadone groups. There were no significant differences in ventricular or atrial arrhythmias, 30-day mortality, 1-year mortality, or days to death. A single intraoperative intravenous methadone dose did not prolong the QTc significantly or increase the incidence of arrhythmias and may be safe in adult cardiac surgical patients.

Background/Objectives: In the current opioid crisis, medical hypnosis has been proposed as an alternative to opioids to control acute and chronic pain. The aim of this study was to use a meta-analysis to conduct an objective assessment of the value of medical hypnosis for the management of acute and chronic pain and opioid consumption. Methods: An initial PubMed search showed 111 relevant studies out of 1115. Twelve randomized controlled studies (RCTs) were identified, published from January 2014 to December 2024, focusing on acute and chronic pain. These RCTs were analyzed to compare the effects of medical hypnosis vs. standard care. Results: The use of medical hypnosis for acute pain was found to decrease pain by 0.54 standard deviations (SD) compared to the standard care, and the effect was medium and statistically significant (95% CI [0.19–0.90]; p = 0.0024). Oral morphine equivalents (OME) in the hypnosis group were 1.5 SD lower than in the placebo group, which was statistically significant (95% CI [0.12, 2.88]; p = 0.03). Unlike the effectiveness of hypnosis for acute pain treatment, hypnosis was not found to have any impact on the treatment of chronic pain. The mean pain value difference in the hypnosis group had little effect and showed a statistically insignificant result—a Hedges’ g score of 0.07 (95% CI [−0.14–0.27]; p = 0.518). Conclusions: The use of medical hypnosis was associated with a statistically significant decrease in acute pain scores and OME, suggesting it is a potential alternative to opioids, but our analysis indicates that hypnosis does not reduce chronic pain.

Introduction: Methadone is an opioid-sparing opioid and it is increasingly used in children undergoing surgery due to its beneficial effects on postoperative pain scores, decreased opioid requirements, and fewer adverse effects compared to other opioids. Intraoperative methadone is not well studied in pediatric cardiac surgery. We hypothesized that intraoperative methadone-based analgesia would provide comparable effectiveness in pain management to non-methadone-based analgesia, including caudal morphine, following pediatric cardiac surgery. Methods: We conducted a retrospective cohort study of 287 children undergoing cardiac surgery using single institutional electronic health records with Society of Thoracic Surgeons database outcomes. Patients were administered intravenous opioids plus caudal morphine (≤6 years) or intravenous opioids in the non-methadone group versus intravenous methadone (two 0.1 mg/kg doses given intraoperatively) with or without additional intraoperative opioids. The primary outcome was postoperative opioid use in morphine milligram equivalents (MME)/kg. Results: This study included 287 pediatric cardiac surgical patients with a mean age of 3.8 years, 59% male, and 72% White. Among 287 patients, 67 (23%) received intraoperative methadone. Unadjusted analysis showed the methadone group had lower postoperative opioid use on the day of surgery (median = 0.3 vs. 0.5 MME/kg, p = 0.005). Adjusted analyses showed there were no significant differences in postoperative opioid use, average pain, maximum pain, antiemetic use, reintubation, and use of naloxone between methadone and non-methadone groups. Hospital length of stay was 2.62 times longer (95% CI: [1.55, 4.41] p < 0.001) in the methadone group vs non-methadone group, but this was only shown in the younger children (≤6 years), who also had higher max pain scores in the methadone group. All outcomes were similar between analgesia groups in older children (>6 years). Conclusions: Intraoperative methadone-based analgesia had comparable effectiveness in postoperative opioid use, pain, and antiemetic use compared to non-methadone-based intraoperative pain management for pediatric cardiac surgery. Large prospective studies of perioperative methadone are needed to examine methadone’s analgesic benefits in children undergoing cardiac surgery.
