Journal: Fentanyl-induced block of hERG channels is exacerbated by hypoxia, hypokalemia, alkalosis, and the presence of hERG1b. (Pubmed Central) - Nov 12, 2020 SIGNIFICANCE STATEMENT: This work demonstrates that heterologously expressed hERG1a/1b channels, which more closely resemble I in the human heart, are blocked by fentanyl with a 3-fold greater potency than the previously studied hERG1a expressed alone. Additionally, chronic hypoxia, hypokalemia, and alkalosis can increase the block of hERG current by fentanyl, potentially increasing the risk of cardiac arrhythmias and sudden death.

Clinical, Journal: Efficacy and Safety in Combining Primary Palatoplasty and Myringotomy in Patients with Cleft Palate. (Pubmed Central) - Nov 11, 2020 This study documents decreased postoperative care unit time and anesthesia drug exposure without increased length of stay or perioperative complications in patients undergoing combined PP and BMT. These results support combining PP and BMT to reduce exposure to potentially neurotoxic medications and to increase efficient utilization of hospital resources.

Clinical, Journal: Evaluation of pain management in medical transfer of trauma patients by air. (Pubmed Central) - Nov 7, 2020 Initial and subsequent dose(s) of analgesic had minimal effect on pain as assessed via numerical rating scale, likely due in part to inadequate dosing. Future research is required to determine and address the barriers to proper analgesia.

Journal: Fentanyl but not Morphine Interacts with Non-Opioid Recombinant Human Neurotransmitter Receptors and Transporters. (Pubmed Central) - Nov 6, 2020 SIGNIFICANCE STATEMENT: The synthetic opioid, fentanyl, induces different clinical effects including rapid onset muscular rigidity, vocal cord closure and rapid death, than the heroin metabolite, morphine. Our data indicate for the first time that the two drugs have very different effects at recombinant human neurotransmitter receptors and transporters that might explain those clinical differences.

The increased utilization of supportive therapy drugs was consistent with the surge in patients with presumed or confirmed COVID-19 during the study period. These data and observations can help clinicians, health-system leaders, manufacturers, wholesalers, and policymakers understand the impact of current and future pandemics on the drug supply chain.

Retrospective data, Review, Journal: To the Editor. (Pubmed Central) - Nov 3, 2020 Based on these results, we suggest that sufentanil and fentanyl may provide comparable effects for IV-PCA after laparoscopic nephrectomy. No abstract available

Clinical, Journal: Efficacy of Periarticular Cocktail Injection in Rheumatoid Patients Undergoing Total Knee Replacement. (Pubmed Central) - Nov 3, 2020 Additional rescue agents used were significantly less at 6 h, at 12 h, and over the first 24 h after the surgery in group A when compared with group B. No cardiac or central nervous system toxicity was observed. Periarticular cocktail injection significantly reduces the requirements for post-operative analgesia and also improves patient satisfaction, with no apparent risks, following total knee arthroplasty in rheumatoid arthritis.

Clinical, Journal: Upper Airway Nerve Block for Rigid Bronchoscopy in the Patients with Tracheal Stenosis: A Case Serie. (Pubmed Central) - Nov 3, 2020 15 patients received fentanyl, and only two patients did not need to intravenous sedation...There was one serious complication (laryngospasm) in one patient. The upper airway nerve block method is a suitable anesthesia technique for patients with tracheal stenosis who are candidates for the tracheal dilatation with rigid bronoscopy, especially when the patient has respiratory distress and has not been evaluated before surgery.

Journal: Racial differences in overdose events and polydrug detection in Indianapolis, Indiana. (Pubmed Central) - Nov 2, 2020 Recent racial disparities in overdose deaths are driven by a combination of fentanyl and cocaine, which disproportionally impacts African American drug users, but may be addressed through expanded harm reduction and community outreach services. Additionally, there is a need to assess the role of differing practices in overdose emergency service provision as a contributing factor to disparities.

Journal: Electrocortical changes associating sedation and respiratory depression by the opioid analgesic fentanyl. (Pubmed Central) - Oct 30, 2020 Interestingly, respiratory rate depression by fentanyl was significantly correlated with increased θ power (R = 0.61, P < 0.001), therefore showing a clear association between electrocortical activity and the magnitude of respiratory rate depression. Overall, we provide new evidence linking specific electrocortical changes to the severity of respiratory depression by opioids, which highlights the importance of considering the cortical and subcortical effects of opioids in addition to their impacts on breathing when evaluating opioid-induced respiratory depression.
