Background: Postoperative secondary hyperalgesia arises from central sensitization due to pain pathways facilitation and/or acute opioid exposure. The latter is also known as opioid-induced hyperalgesia (OIH). Remifentanil, a potent μ-opioid agonist, reportedly induces postoperative hyperalgesia and increases postoperative pain scores and opioid consumption. The pathophysiology underlying secondary hyperalgesia involves N-methyl-D-aspartate (NMDA)-mediated pain pathways. In this study, we investigated whether perioperatively infusing low-dose buprenorphine, an opioid with anti-NMDA activity, in patients receiving remifentanil infusion prevents postoperative secondary hyperalgesia...

We present the case of an 8‑year-old female child with suspected peroxisomal disorder requiring general anesthesia for adenotomy, paracentesis and brainstem-evoked response audiometry. Peroxisomes are small intracellular organelles that catalyse key metabolic reactions. Peroxisomal disorders are a heterogeneous group of rare genetic diseases. Anesthesia can be challenging as adrenal insufficiency, mental retardation, muscle weakness, risk of pulmonary aspiration, airway complications, seizure disorders and altered pharmacokinetics and pharmacodynamics can occur in these patients but guidelines for anesthesia do not exist due to the heterogeneity and rarity of these diseases and case reports are rare...

Remifentanil is one of the most frequently prescribed opioids used in combination with inhalation anesthetics in clinical practice, but the effects of such combinations on the developing rat brain are unknown. In our study, we investigated first the potential neurotoxic effects of remifentanil on the developing brain and then the effects of remifentanil on isoflurane-induced apoptosis in the neonatal rat brain following exposure to a nociceptive stimulus. In the first experiment, postnatal day (P) 7 rats were randomly exposed to 30% oxygen, 1...

Objective: Several reports have shown the negligible adverse effects of low-dose remifentanil on the autonomic nervous system. We propose that the administration of low-dose remifentanil would be beneficial without adverse respiratory and hemodynamic effects. This study aimed to examine the effects of low-dose remifentanil on postoperative pain relief and heart rate variability (HRV) after surgery. Methods: In total, 20 patients, who underwent breast cancer surgery, were analysed for HRV in the post-anaesthesia care unit (PACU)...

REVIEW
Bryan Anderson
Pain control in parturients can be particularly challenging for the hospital staff. To achieve optimal outcomes in anesthesia patients, it is important to consider multiple options for pain control, especially when traditional options pose a problem or are not options. In particular, there are parturient clients for whom the use of neuraxial anesthesia (epidural and spinal blockade) is not an option. One option that warrants consideration for patient centered anesthesia practice is the use of remifentanil.

Remote ischemic preconditioning (RIPC) seems to be a promising cardioprotective strategy with contradictive clinical data suggesting the anesthetic regimen influencing the favorable impact of RIPC. This study aimed to investigate whether cardio protection by RIPC is abolished by anesthetic regimens. Male Wistar rats were randomized to 6 groups. Anesthesia was either maintained by pentobarbital (Pento) alone or a combination of sevoflurane (Sevo) and remifentanil or propofol (Prop) and remifentanil in combination with and without RIPC...

Background The use of Propofol and Remifentanil for analgosedation in children is common and safe. For sedation monitoring clinical scores as Comfort Score (CS) as well as bispectral index (BIS) are frequently applied. The impact of BIS for sedation monitoring in pediatric patients is still under debate. This prospective study aims to investigate whether dual sedation monitoring of CS and BIS compared with monitoring of CS alone during muscle biopsies in children can reduce sedative doses, reduce awakening time and prevent complications...
