BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) is a gastrointestinal procedure that requires a relatively motionless patient during the intervention. Deep sedation by intravenous propofol combined with an opioid has recently become the preferred sedation technique. However, when high doses of propofol are used, side effects, namely respiratory depression, may occur. Esketamine has hypnotic, analgesic, and sympathomimetic effects. Our assumption is that a combination of propofol with esketamine reduces the dosage of individual drugs, thereby minimizing sedation side effects while keeping the same satisfaction level of patients and endoscopists...

WHAT IS KNOWN AND OBJECTIVE: Beginning in the 1950s, a family of potent opioids was synthesized and developed (fentanyl and analogues). They continue to serve as valuable analgesic agents. But the recent spike and notoriety of their abuse has raised alarm, even calls for tighter control. We review the trajectory of these compounds. COMMENT: To rectify shortcomings of the then available opioid analgesics, an analogue family of compounds was synthesized having a piperidine ring (presumptive principal active moiety in morphine and meperidine)...

Volatile agents for anaesthesia are widely used for anaesthetizing laboratory primates, and isoflurane is one of the most frequently used agents. Sevoflurane has been shown to offer a more rapid recovery than isoflurane in a number of species, but no comparisons have been made in non-human primates. This study compared the recovery characteristics of isoflurane and sevoflurane in rhesus macaques undergoing experimental neurosurgery. Twelve primates (7 males and 5 females) were randomly allocated to the treatment groups...

The steady appearance of new fentanyl analogues and the associated overdose deaths require the development of sensitive screening approaches to detect these compounds in biological samples and seizures. We developed a targeted screening method to detect 50 4-anilidopiperidine-related fentanyl analogues in whole blood using ultrahigh performance liquid chromatography quadrupole time-of-flight mass spectrometry in data-independent acquisition mode. Sample preparation was performed using protein precipitation on a fully automated robotic setup...

Victoria C Ziesenitz, Janelle D Vaughns, Gilbert Koch, Gerd Mikus, Johannes N van den Anker
Fentanyl and its derivatives sufentanil, alfentanil, and remifentanil are potent opioids. A comprehensive review of the use of fentanyl and its derivatives in the pediatric population was performed using the National Library of Medicine PubMed. Studies were included if they contained original pharmacokinetic parameters or models using established routes of administration in patients younger than 18 years of age. Of 372 retrieved articles, 44 eligible pharmacokinetic studies contained data of 821 patients younger than 18 years of age, including more than 46 preterm infants, 64 full-term neonates, 115 infants/toddlers, 188 children, and 28 adolescents...

Easy-to-use naloxone formulations are needed to help address the opioid overdose epidemic. The pharmacokinetics of i.v., i.m., and a new i.n. naloxone formulation (2 mg) were compared in six healthy volunteers. Relative to i.m. naloxone, geometric mean (90% confidence interval [CI]) absolute bioavailability of i.n. naloxone was modestly lower (55%; 90% CI, 43-70% vs. 41%; 90% CI, 27-62%), whereas average (±SE) mean absorption time was substantially shorter (74 ± 8.8 vs. 6.7 ± 4.9 min). The opioid-attenuating effects of i...

Experimental interventions that activate specific components of clinical pain are necessary for characterization of underlying mechanisms and pharmacology. Cutaneous hyperalgesia has been described that uses nonpainful heat to induce secondary hyperalgesia. This study evaluated the effect of intravenous alfentanil on experimental cutaneous hyperalgesia created using this method. Eighteen subjects participated in a randomized, double-blinded, placebo-controlled crossover study consisting of 2 sessions, 1 with alfentanil and 1 with placebo...

The present study was conducted to determine the combined analgesic effect of alfentanil and propofol in the formalin test. Diluted formalin was injected into the dorsal surface of the right hind paw in rats. Nociceptive behavior was determined by counting the number of flinches of the injected paw for 1 h after injection; a reduction in formalin‑induced flinching was interpreted as an antinociceptive effect. Isobolographic analysis was used to determine the type of antinociceptive interaction (additivity, antagonism or synergism)...

Doxapram is an analeptic that induces ventilatory stimulation and increases blood pressure and cardiac output (CO). Its mechanism of action is blockade of background K(+) -channels expressed on type 1 carotid body cells. In the randomized controlled trial, the authors explored the role of the increase in CO by doxapram (plasma concentration (Cp) 1000-3,500 ng/mL) on the pharmacokinetics (PK) and pharmacodynamics of the potent opioid alfentanil (Cp 100-200 ng/mL). Population PK-PD analyses were performed on the doxapram PK-CO data and the alfentanil PK-antinociception data...

Empirical mode decomposition (EMD) is an adaptive filter bank for processing nonlinear and non-stationary signals, such as electroencephalographic (EEG) signals. EMD works well to decompose a time series into a set of intrinsic mode functions with specific frequency bands. An IMF therefore represents an intrinsic component on its correspondingly intrinsic frequency band. The word of 'intrinsic' means the frequency is totally adaptive to the nature of a signal. In this study, power density and nonlinearity are two critical parameters for characterizing the amplitude and frequency modulations in IMFs...

M Nazir, B Salim, F A Khan
The primary aim of this review was to assess the effect of pharmacological agents administered to attenuate the haemodynamic response to tracheal intubation in paediatric patients up to 16 years of age undergoing elective surgery. Secondary aims were to identify adverse effects related to these agents, and the agents' roles in decreasing arrhythmias. A systematic search was conducted for articles listed in PubMed, CINAHL or the Cochrane database between January 1980 and June 2014. We included randomised controlled trials where the stated aim of the study included observing the effects of pharmacological agents on the haemodynamic response to tracheal intubation...
