Filter by:The aim of this study will be to investigate the effect of opioid-free induction versus opioid-based induction on hemodynamic response and nociception level index during elective operations
To compare whether 5 μg dexmedetomidine with 25 μg fentanyl added to 0.5% hyperbaric bupivacaine as adjuvants in spinal anaesthesia in patients undergoing appendectomy could reduce intraoperative peritoneal related symptoms.
The objective of this study is to evaluate the effect of adding dexmedetomidine on evoked potentials in adult patients undergoing spinal surgery under intravenous anesthesia
Fentanyl and esketamine are both standard of care for treatment of acute severe traumatic pain in the prehospital setting in the Netherlands. However, it is not known whether they are equally effective and safe. It is also not known whether intranasal (IN) administration of fentanyl or esketamine is equally effective and safe as intravenous (IV) administration. The FORE-PAIN trial is a double-blind multi-arm randomized non-inferiority trial comparing Fentanyl IN, esketamine IV and esketamine IN (intervention arms) to fentanyl IV (comparator arm) for prehospital management of traumatic pain. The investigators hypothesize that all intervention arms provide analgesia that is non-inferior to the comparator arm, and that all study arms are equally safe.
Fentanyl is an opioid drug used as analgesic and anaesthetic also in Neonatal Intensive Care Units (NICU), according to the last national and international recommendations, during invasive life support strategies such as mechanical ventilation. Opioids manifest their sedative effect through activation of μ-opioid receptors, which are abundant both in the central and peripheral nervous system. Comparing fentanyl to morphine we can appreciate a much more powerful effect (75-220 major) with lower doses to obtain similar analgesic effect; these characteristics are due to the high lipophilicity of the molecule which easily crosses the blood-brain barrier (BBB). At the same time, fentanyl shows less adverse effects than morphine such as vomiting, nausea, gastrointestinal constipation, respiratory depression, dependence and tolerance. The drug is extensively metabolized by liver enzymes. In routinary clinical practice it has been observed that large interindividual differences are found in the daily dosages needed to achieve pain control. Literature evidences that pharmacodynamic variation related to genotypes in receptor signalling or pain modulators may play an important role in this variability. Many genes are related to fentanyl pharmacodynamics and pharmacokinetics. Some polymorphism in these genes are already known to correlate with toxicity or efficacy of the drug, also in the paediatric population. More polymorphisms could be involved in abnormal pharmacodynamic or pharmacokinetics of fentanyl, therefore studies are necessary to better explain the possible role of pharmacogenetics in precision medicine especially in a very specific population as newborn.
The goal is to determine whether fentanyl and morphine have similar effects in reducing aspirin's effect upon platelets in emergency department patients with chest discomfort. Morphine has been shown to worsen outcomes in heart attack patients due to reduction of oral anti-platelet agent effectiveness and so many providers have switches to using fentanyl. However, it is largely unknown whether fentanyl has similar effects.
The aim of this study will be to investigate the effect of an opioid-free anesthesia regimen with a mixture of dexmedetomidine-lidocaine-ketamine in the same syringe versus fentanyl analgesia in elective thyroidectomies. Recovery parameters and nociception levels throughout the operation will be evaluated
Chronic sinusitis (CRS) is a high incidence disease characterized by pus, nasal obstruction, olfactory disturbance, headache, and other symptoms, lasting for more than 12 weeks, with severe cases having ocular compression and visual impairment, which can cause cranial, eye, and lung complications. Chronic sinusitis is a high-risk disease.
Purpose: This study aimed to investigate the impact of CYP3A4*1G genetic polymorphism on non-analgesic effects of fentanyl in Chinese Han patients. Methods: 200 patients receiving elective surgery under general anesthesia were recruited into this study. Venous blood was withdrawn for genotyping of CYP3A4*1G before operation. Fentanyl 2 µg/kg was administered preoperatively. Bispectral Index (BIS), Respiratory rate(RR), etc at Tb (entering room), T0 (drug administration), T1 (2min), T2 (4min), T3(6min), T4(8min), T5(10min), T6(20min) were recorded.
