Assessment of the antinociceptive effect of a single fentanyl bolus dose in children: A pharmacokinetic and pharmacodynamic analysis based on the nociception level index during sevoflurane general anesthesia.
The Nociception Level Index has shown benefits in estimating the nociception/antinociception balance in adults, but there is limited evidence in the pediatric population. Evaluating the index performance in children might provide valuable insights to guide opioid administration. ⋯ The Nociception Level Index showed superior capability compared to traditional hemodynamic variables in discriminating different nociception-antinociception levels during varying fentanyl concentrations in children under sevoflurane anesthesia.

Increases in opioid prescriptions have been described; however, recent trends and prescribing patterns of analgesics in Dutch general practice are largely unknown. ⋯ Considering the increase in strong opioid prescriptions for benign conditions, GPs need to be vigilant for patients who are at risk for chronic use. Regular monitoring and awareness for psychosocial factors in treatment of chronic pain may be key in preventing harms associated with persistent opioid use.

Managing postoperative pain in patients with obesity is challenging. Although multimodal analgesia has proved effective for pain relief, the specific impacts of different nonopioid i.v. analgesics and adjuvants on these patients are not well-defined. This study aims to assess the effectiveness of nonsteroidal antiinflammatory drugs, paracetamol, ketamine, α-2 adrenergic receptor agonists, lidocaine, magnesium, and oral gabapentinoids in reducing perioperative opioid consumption and, secondarily, in mitigating the occurrence of general and postoperative pulmonary complications (POPCs), nausea, vomiting, PACU length of stay (LOS), and hospital LOS among surgical patients with obesity. ⋯ CRD42023399373 (PROSPERO).

Randomized Controlled Trial Comparative StudyComparing the haemodynamic effects of high- and low-dose opioid anaesthesia: a secondary analysis of a randomised controlled trial.
Post-induction hypotension (MAP < 65 mmHg) occurs frequently and is usually caused by the cardiovascular adverse effects of the anaesthetic induction drugs used. We hypothesize that a clinically significant difference in the incidence and severity of hypotension will be found when different doses of propofol and remifentanil are used for induction of anaesthesia. ⋯ Induction of anaesthesia with different predicted equipotent combinations of propofol and remifentanil did result in statistically different but clinically irrelevant differences in haemodynamic endpoints during induction of anaesthesia. Our study could not identify preferable drug combinations that decrease the risk for hypotension after induction, although they all yield a similar predicted PTOL.

Optimizing the Dosing Regimen During Rotation From Subcutaneous to Transdermal Administration of Fentanyl.
Subcutaneous (SC) administration of fentanyl allows for rapid dose titration to treat urgent cancer-related pain. After establishing the optimal fentanyl dose, patients typically rotate towards transdermal (TD) fentanyl patches. Continuing the SC fentanyl up to 12h after application of the patch led to elevated fentanyl concentrations and fentanyl-related toxicities. Based on these findings, and simulations using a pharmacokinetic (PK) model, SC fentanyl administration was discontinued immediately following the application of the patch. ⋯ The updated rotation scheme, implying a 1:1 dose conversion and discontinuation of SC fentanyl directly after rotation, resulted in equivalent fentanyl exposure pre and post-rotation. Moreover, the dosing regimen showed to be safe and efficacious during rotation. The new dosing regimen when rotating from SC to TD fentanyl can be effectively and safely implemented in routine palliative care.
