Recently, the cognitive abilities of patients with amyotrophic lateral sclerosis (ALS) have been found to be impaired along with the neurodegeneration of motor neurons. Electroencephalography (EEG) of end-stage ALS patients has reportedly shown specific features based on neuronal network modulations, differing from EEG of other patients with cognitive failure and dementia. However, EEG of end-stage ALS patients during anaesthesia has not yet been reported. A 64-year-old male ALS patient with locked-in state (LIS), supported by tracheostomy positive-pressure ventilation (TPPV) and enteral nourishment for 9years, underwent scheduled general anaesthesia for repair of a fractured mandible...

BACKGROUND AND AIMS: Desflurane and sevoflurane have low blood gas solubility co-efficients, allowing a rapid awakening from anaesthesia. However, desfluraneis pungent and may cause airway irritability. We compared desflurane and sevoflurane with respect to recovery and occurrence of adverse airway responses in spontaneously breathing patients while using the ProSeal™ laryngeal mask airway (LMA). METHODS: Ninety-four adult patients undergoing hysteroscopic procedures were divided into sevoflurane (S) group or desflurane (D) group...

Background: Kidney transplantation is associated with harmful processes affecting the viability of the graft. One of these processes is associated with the phenomenon of ischaemia-reperfusion injury. Anaesthetic conditioning is a widely described strategy to attenuate ischaemia-reperfusion injury. We therefore conducted the Volatile Anaesthetic Protection of Renal Transplants-1 trial, a pilot project evaluating the influence of two anaesthetic regimens, propofol- vs sevoflurane-based anaesthesia, on biochemical and clinical outcomes in living donor kidney transplantation...

PURPOSE: Pre and post-operative administration of sevoflurane in myocardial revascularization surgery provides enhanced cardioprotective effects exerted by pharmacologic pre- and post-conditioning, as compared to propofol. The identification of the enzymes involved in conditioning mechanisms is crucial to the understanding of the effects of sevoflurane in cardiac surgery patients. The impact of sevoflurane on another crucial target organ-the kidney-was also assessed. METHODS: Ninety patients undergoing off-pump myocardial revascularization surgery were allocated to receive either intra- and postoperative sevoflurane (SS), intraoperative sevoflurane and postoperative propofol (SP), or intra- and postoperative propofol (PP))...

Cerebral ischemia leads to astrocyte's activation and glial scar formation. Glial scar can inhibit axonal regeneration during the recovery phase. It has demonstrated that sevoflurane has neuroprotective effects against ischemic stroke, but its effects on ischemia-induced formation of astrogliosis and glial scar are unknown. This study was designed to investigate the effect of sevoflurane postconditioning on astrogliosis and glial scar formation in ischemic stroke model both in vivo and in vitro. The results showed that 2...

BACKGROUND: The second trimester is a period of neurogenesis and neuronal migration, which can be affected by exposure to anesthetics. Studies also suggest that multiple exposures may have a greater impact on neurodevelopment. AIM: We investigated whether in utero single or multiple exposures to anesthetics caused long-term behavior changes. METHODS: Pregnant mice were randomly divided into four groups on gestational day 14 (GD 14). Mice in the Control × 1 group were exposed to 100% oxygen for 150 min...

Background.: Anaesthesia can induce cognitive deficiency in young rodents and monkeys. Mitochondrial dysfunction contributes to the anaesthesia-induced neurotoxicity and neurobehavioural deficits. We therefore assessed the effects of the mitochondrial energy enhancer coenzyme Q 10 (CoQ 10 ) on anaesthesia-induced cognitive deficiency in young mice to investigate the role of mitochondrial dysfunction. Methods.: Young mice ( n =134) were randomly assigned into the following four groups: control plus corn oil vehicle (60% oxygen); 3% sevoflurane [2 h daily on postnatal day (P) 6, 7, and 8] plus vehicle; CoQ 10 (50 mg kg -1 ) plus vehicle; or 3% sevoflurane plus CoQ 10 plus vehicle...

Sevoflurane and isoflurane are volatile halogenated ether widely used in anesthesia. Both have comparable potency and easy titratability but sevoflurane has lower pungency and results in faster patient recovery. Isoflurane, however, is more affordable. The nephrotoxicity of sevoflurane is undisputed but studies on isoflurane nephrotoxicity are lacking. The objective of this paper is to determine the overall nephrotoxicity profile of sevoflurane and isoflurane in donor nephrectomy patients using the renal function markers - nuclear glomerular filtration rate (GFR), serum creatinine, urine protein-to-creatinine ratio, proteinuria, and glucosuria...

Balanced anesthesia allows for a reduced dosage of each component, while inducing general anesthesia of sufficient depth with potentially fewer side effects. Here, we compare two anesthetic protocols combining sevoflurane anesthesia with pre-medication (ketamine [K] or fentanyl-midazolam [FM]) to a sevoflurane monoanesthesia (S) concerning their ability to provide reliable anesthesia suitable for moderate surgery in laboratory mice. Twenty-one female C57BL/6J mice assigned randomly to one of three protocols underwent a 50-min anesthesia and a sham embryo transfer...

Sevoflurane has been reported to induce neurotoxicity and cognitive impairment in the developing brains. However, the underlying molecular mechanisms remain poorly understood. Recent studies have demonstrated aberrant cyclin-dependent kinase 5 (CDK5) activity is implicated in inhaled anesthetic-induced neurotoxicity. CDK5/CRMP2 signaling is involved in the cortical and hippocampal dendritic development. The aim of present study is to investigate whether the CDK5/CRMP2 pathway mediates sevoflurane-induced dendritic development abnormalities...

BACKGROUND: The incidence of nasal secretions into the operative field is as high as 5% in ophthalmic surgery under general anesthesia. It may induce postoperative endophthalmitis. Secretions under propofol-based total intravanous anesthesia (TIVA) are greater than sevoflurane anesthesia during surgery. Postoperative nausea and vomiting (PONV) after inhalational anesthesia is higher than TIVA and may increase intraocluar pressure. We investigated the effect of sevoflurane combination with propofol-based TIVA on nasopharyngeal secretions and PONV in ocular surgery...
