RESUMEN

OBJECTIVE: This study aimed to determine whether there is a difference in pain scores and opioid consumption after elective surgery in patients maintained on methadone or buprenorphine for opioid use disorder (OUD). Additionally, we investigated the impact of continuing or discontinuing methadone or buprenorphine on post-operative pain outcomes. DESIGN: A single-center retrospective cohort study. SETTING: Tertiary care medical center. PATIENTS AND PARTICIPANTS: Adults aged 18 years or older with OUD maintained on buprenorphine or methadone who underwent elective surgery between January 1, 2017, and January 1, 2021. INTERVENTIONS: Patients were identified through electronic medical records, and demographic and clinical data were collected. MAIN OUTCOME MEASURES: The primary outcome was opioid consumption at 24 hours post-operatively, measured in milligram morphine equivalents. The secondary outcome was opioid consumption and pain scores up to 72 hours post-operatively, assessed using a numeric rating scale. RESULTS: This study included 366 patients (64 percent on buprenorphine and 36 percent on methadone). Opioid utilization significantly increased when buprenorphine was not administered post-operatively. Both groups exhibited comparable total opioid consumption during the post-operative period. In the buprenorphine cohort, pain scores differed significantly based on the receipt of medications for OUD post-operatively. CONCLUSIONS: This study reinforces existing evidence supporting the continuation of medications for opioid use disorder, specifically buprenorphine and methadone, during the perioperative period. Dissemination of guideline recommendations is essential to ensure optimal post-operative pain management for this patient population.

RESUMEN

The removal of the X-waiver in the Mainstreaming Addiction Treatment (MAT) Act of 2023 has substantial implications for buprenorphine prescribing as one of the options to treat opioid use disorder. The purpose of this commentary is to discuss the unanswered questions regarding buprenorphine in the intensive care unit (ICU) including how the passage of the MAT Act will affect ICU providers, which patients should receive buprenorphine, what is the most appropriate route of administration and dose of buprenorphine, what medications interact with buprenorphine, and how can transitions of care be optimized for these patients.

RESUMEN

Chemokines, a family of chemotactic cytokines, mediate leukocyte migration to and entrance into inflamed tissue, contributing to the intensity of local inflammation. We performed an analysis of chemokine and immune cell responses to cardiac arrest (CA). Forty-two patients resuscitated from cardiac arrest were analyzed, and twenty-two patients who underwent coronary artery bypass grafting (CABG) surgery were enrolled. Quantitative antibody array, chemokines, and endotoxin quantification were performed using the patients blood. Analysis of CCL23 production in neutrophils obtained from CA patients and injected into immunodeficient mice after CA and cardiopulmonary resuscitation (CPR) were done using flow cytometry. The levels of CCL2, CCL4, and CCL23 are increased in CA patients. Temporal dynamics were different for each chemokine, with early increases in CCL2 and CCL4, followed by a delayed elevation in CCL23 at forty-eight hours after CA. A high level of CCL23 was associated with an increased number of neutrophils, neuron-specific enolase (NSE), worse cerebral performance category (CPC) score, and higher mortality. To investigate the role of neutrophil activation locally in injured brain tissue, we used a mouse model of CA/CPR. CCL23 production was increased in human neutrophils that infiltrated mouse brains compared to those in the peripheral circulation. It is known that an early intense inflammatory response (within hours) is associated with poor outcomes after CA. Our data indicate that late activation of neutrophils in brain tissue may also promote ongoing injury via the production of CCL23 and impair recovery after cardiac arrest.

RESUMEN

OBJECTIVE: We hypothesized that the administration of amantadine would increase awakening of comatose patients resuscitated from cardiac arrest. METHODS: We performed a prospective, randomized, controlled pilot trial, randomizing subjects to amantadine 100 mg twice daily or placebo for up to 7 days. The study drug was administered between 72 and 120 hours after resuscitation and patients with absent N20 cortical responses, early cerebral edema, or ongoing malignant electroencephalography patterns were excluded. Our primary outcome was awakening, defined as following two-step commands, within 28 days of cardiac arrest. Secondary outcomes included length of stay, awakening, time to awakening, and neurologic outcome measured by Cerebral Performance Category at hospital discharge. We compared the proportion of subjects awakening and hospital survival using Fisher exact tests and time to awakening and hospital length of stay using Wilcoxon rank sum tests. RESULTS: After 2 years, we stopped the study due to slow enrollment and lapse of funding. We enrolled 14 subjects (12% of goal enrollment), seven in the amantadine group and seven in the placebo group. The proportion of patients who awakened within 28 days after cardiac arrest did not differ between amantadine (n=2, 28.6%) and placebo groups (n=3, 42.9%; P>0.99). There were no differences in secondary outcomes. Study medication was stopped in three subjects (21.4%). Adverse events included a recurrence of seizures (n=2; 14.3%), both of which occurred in the placebo group. CONCLUSION: We could not determine the effect of amantadine on awakening in comatose survivors of cardiac arrest due to small sample size.
