We have compared two groups of patients given low- or high-dose fentanyl anaesthesia. Arterial blood samples were collected for measurement of glucose, free fatty acids (FFA), glycerol, beta-hydroxy-butyrate, insulin, c-peptide, glucagon, human growth hormone (HGH), cortisol and adrenaline concentrations. After induction of anaesthesia, blood concentrations of most of these substances decreased. After the start of surgery the concentrations of cortisol, glucose, HGH, FFA and beta-hydroxy-butyrate increased significantly in the group anaesthetized with the lower dose of fentanyl. In the group that received high-dose fentanyl anaesthesia the plasma concentrations of almost all the hormones and substances measured remained relatively low. The differences between the two groups during surgery were significant for adrenaline (P less than 0.001) and cortisol (P less than 0.001). High-dose fentanyl appears to block the trauma-induced stress response seen in patients anaesthetized with low dose fentanyl.

Background: The effect of anesthesia methods on non-muscle invasive bladder cancer (NMIBC) recurrence post-resection remains uncertain. We aimed to compare the oncological outcomes of spinal anesthesia (SA) and general anesthesia (GA) in patients with NMIBC.
Methods: This prospective randomized controlled trial recruited 287 patients with clinical NMIBC at Seoul National University Hospital from 2018 to 2020.
Comparison of Bupivacaine plus Dexmedetomidine versus Bupivacaine plus Fentanyl for Caudal Block in Pediatric Infraumbilical Surgery.

Different additives have been used to improve the duration and quality of analgesia of the local anaesthetic used in the single-dose caudal block technique, such as opioids, epinephrine, clonidine, neostigmine, etc. Dexmedetomidine is a potent and a highly selective α2-adrenergic agonist having a sympatholytic, sedative, and analgesic effect and has been described as a safe and effective additive in many anaesthetic and analgesic techniques. Another agent is Fentanyl, a lipophilic opioid, is added frequently to local anaesthetics which least likely to cause respiratory depression when given extradurally, because of its high lipid solubility.

Department of Molecular Biotechnology, Central Laboratory Unit, University Nacional Hermilio Valdizán, Huánuco, Perú.
Background: The limited and detailed literature on total intravenous anesthesia (TIVA), as well as the clinical indications for unilateral ovariectomy in llamas, are not well-defined. Therefore, it is necessary to understand the anesthetic events and the surgical intervention in this species.
Aim: The objective of this study was to evaluate the intraoperative physiological and clinical parameters in llamas undergoing unilateral ovariectomy, under three protocols of TIVA.
Anesthetic management using desflurane and nitrous oxide in a child with non-ketotic hyperglycinemia: a case report.

Department of Anesthesiology, Niigata University Medical and Dental Hospital, 1-754 Asahimachi-Dori, Chuo-Ku, Niigata, 951-8520, Japan.
Background: Non-ketotic hyperglycinemia (NKH) is a rare autosomal recessive disorder caused by defects in the glycine cleavage system, leading to elevated glycine levels in the central nervous system. NKH manifests in various forms, with the neonatal type being the most severe and often associated with high mortality and significant neurological impairment. This case report highlights the successful uses of desflurane and nitrous oxide for anesthetic management in a patient with NKH.

Introduction: Use of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is still in the focus of research, in which pigs are commonly involved. During VA-ECMO, cardiovascular parameters are artificially manipulated and therefore not reliable indicators of nociception. Nociceptive withdrawal reflex (NWR) thresholds can be a suitable alternative in such a context.
