AIM: To develop an electromyography method for pregnant rat uterus in vivo and to separate myometrial signals from the gastrointestinal tract signals. METHODS: Pregnant Sprague-Dawley rats (n=8) were anaesthetized and their stomach, small intestine, and large intestine were removed from the abdomen. A pair of thread electrodes was inserted into the uterus, while a pair of disk electrodes was placed subcutaneously above the myometrium. Additionally, a strain gauge sensor was fixed on the surface of the myometrium and cecum for the parallel detection of mechanical contractions in rats (n=18) with intact gastrointestinal tract...

Whether oxygen should be administered acutely during ST-segment elevation myocardial infarction is debated. Despite this controversy, the possible influence of supplementary oxygen on animal models of ischaemia-reperfusion injury or cardioprotection is rarely considered. We used an in vivo mouse model of ischaemia and reperfusion to investigate the effect of ventilation with room air versus 100% oxygen. The coronary artery of anaesthetized mice was occluded for 40 min. followed by 2-hrs reperfusion. Infarct size was measured by tetrazolium staining and expressed as a percentage of area at risk, determined using Evan's blue...

BACKGROUND: There is little evidence concerning the effect of sevoflurane in outpatient procedural sedation, especially in children. We hypothesised that the addition of sevoflurane to a sedation regimen improves children's behaviour with minimal adverse events. METHODS: This is a randomised, triple-blind clinical trial conducted on an outpatient basis. Participants were 27 healthy children aged 4 to 6 years, who previously refused dental treatment with non-pharmacologic methods...

Almost 30 years ago, the American Academy of Pediatrics Committee on Fetus and Newborn coauthored a policy statement strongly advocating for the use of anaesthesia in all neonates stating 'local or systemic pharmacologic agents now available permit relatively safe administration of anesthesia or analgesia to neonates undergoing surgical procedures and that such administration is indicated according to the usual guidelines for the administration of anesthesia to high-risk, potentially unstable patients'. With current techniques and advanced monitoring, preterm and full-term infants routinely undergo surgical procedures under general anaesthesia to repair congenital defects that were lethal in years past...

BACKGROUND: Transdermal drug delivery represents an extremely attractive and innovative route across the skin owing to the possibility for achieving systemic effect of drugs. Present scenario demands a special focus on developing safe medicine with minimize toxic adverse effects related to most of the pharmacologically active agents. Transdermal drug delivery would be a focal paradigm which provides patient convenience, first-pass hepatic metabolism avoidance, local targeting and reduction in toxic effect related to various categories of drugs like, analgesics, anti-inflammatory, antibiotics, antiviral, anaesthetic, anticancer etc...

Studies in mice using resting-state functional magnetic resonance imaging (rs-fMRI) have provided opportunities to investigate the effects of pharmacological manipulations on brain function and map the phenotypes of mouse models of human brain disorders. Mouse rs-fMRI is typically performed under anaesthesia, which induces both regional suppression of brain activity and disruption of large-scale neural networks. Previous comparative studies using rodents investigating various drug effects on long-distance functional connectivity (FC) have reported agent-specific FC patterns, however, effects of regional suppression are sparsely explored...

BACKGROUND: Preoperative anxiety negatively influences children's anaesthetic and surgical experience, and results in postoperative complications, such as emergence delirium and behavioural changes. Nonpharmacological management using alternative therapies that alleviate psychological stress can be as important as pharmacological ones in reducing children's anxiety. Nevertheless, their validity as an effective anxiety-reducing strategy in children remains controversial. OBJECTIVE(S): To verify whether nonpharmacological strategies, that is, leaflet and distraction with smartphone application presented to parents/guardians and children, respectively, were effective in preventing children's anxiety during anaesthesia induction...

BACKGROUND: The operating theatre, anaesthesia induction and separation from parents create fear and anxiety in children. Anxiety leads to adverse behavioral changes appearing and sometimes persisting during the postoperative period. Our aim was to compare the effects of midazolam (0.3 mg kg(-)(1): MDZ) for premedication with age-appropriate tablet game apps (TAB) on children anxiety during and after ambulatory surgery. METHODS: A randomized controlled trial was conducted from May 16th, 2013 to March 25th, 2014 at the Children Hospital of Lyon...

OBJECTIVES: Modified drug delivery systems have been developed to improve pharmacological properties of local anaesthetics. However, the inflammatory potential of these formulations was not investigated. This study compared the in-vitro effects of ropivacaine (ropi) in plain, liposomal (MLV) or 2-hydroxypropyl-β-cyclodextrin (HP-β-CD) formulations on cell viability, apoptosis and cytokine (IL-1α, TNF-α, IL-6 and IL-10) release. METHODS: Human immortalized keratinocytes (HaCaT) and human immortalized gingival fibroblasts (HGF) were exposed to 1-100 μm ropi concentrations...

BACKGROUND: Understanding the patient perspective on healthcare is central to the evaluation of quality. This study measured selected patient-reported outcomes after anaesthesia in order to identify targets for research and quality improvement. METHODS: This cross-sectional observational study in UK National Health Service hospitals, recruited adults undergoing non-obstetric surgery requiring anaesthesia care over a 48 h period. Within 24 h of surgery, patients completed the Bauer questionnaire (measuring postoperative discomfort and satisfaction with anaesthesia care), and a modified Brice questionnaire to elicit symptoms suggestive of accidental awareness during general anaesthesia (AAGA)...

BACKGROUND: RCTs testing surgical interventions can change clinical practice. The adequate reporting of surgical trials is an important issue. METHODS: A cross-sectional survey was undertaken by searching PubMed for two-arm parallel randomized trials assessing surgical interventions published in 2003 or 2013. Quality of reporting was evaluated against the CONSORT checklist containing 29 items (standard CONSORT plus CONSORT Extension for Trials Assessing Non-Pharmacological Treatments)...

OBJECTIVES: Although less often requested in comparison with dogs, the collection of semen in cats can be necessary for artificial insemination, for semen evaluation in tom cats used for breeding and for semen storage. Urethral catheterisation after pharmacological induction with medetomidine has proved to be useful for the collection of semen in domestic cats. However, most of the previously used protocols require the administration of high doses of medetomidine that can increase the risk of side effects, especially on the cardiovascular system...

REVIEW
Udo Bonnet
Ketamine is approved to start and maintain anaesthesia or analgesia. Ketamine is also known to be neurotoxic and an old drug of abuse. Numerous studies have proven a rapid and strong antidepressant response (AR) following parenteral sub-anaesthetic ketamine doses when applied the first time to patients with treatment resistant unipolar or bipolar major depression. This rapid and robust AR is encouraging, though short-lived (usually up to seven days). There is growing evidence that repeated und escalating ketamine administrations exert longer-lasting AR than single infusions...

Polpun Boonmak, Suhattaya Boonmak, Malinee Laopaiboon
BACKGROUND: Functional endoscopic sinus surgery (FESS) is a minimally invasive technique that is used to treat chronic sinusitis. Small bleeding areas can reduce operative visibility and result in destruction of surrounding structures. Deliberate hypotension (lowering the mean arterial blood pressure to between 50 and 65 mm Hg in normotensive patients) using a range of pharmacological agents during general anaesthesia reduces blood loss in many operations. This review was originally published in 2013 and updated in February 2016...

B G Challis, R T Casey, H L Simpson, M Gurnell
Phaeochromocytomas and paragangliomas (PPGLs) are catecholamine secreting neuroendocrine tumours that predispose to haemodynamic instability. Currently, surgery is the only available curative treatment, but carries potential risks including hypertensive and hypotensive crises, cardiac arrhythmias, myocardial infarction and stroke, due to tumoral release of catecholamines during anaesthetic induction and tumour manipulation. The mortality associated with surgical resection of PPGL has significantly improved from 20-45% in the early 20th century (Apgar & Papper, AMA Archives of Surgery, 1951, 62, 634) to 0-2·9% in the early 21st century (Kinney et al...

Yao Wang, Yu-Zhang Liu, Shi-Yi Wang, Zhiru Wang
As a critical technique for dissection of synaptic and cellular mechanisms, whole-cell patch-clamp recording has become feasible for in vivo preparations including both anaesthetized and awake mammalian brains. However, compared with in vitro whole-cell recording, in vivo whole-cell recording often suffers from low success rates and high access resistance, preventing its wide application in physiological analysis of neural circuits. Here, we describe experimental procedures for achieving in vivo amphotericin B-perforated whole-cell recording as well as conventional (breakthrough) whole-cell recording from rats and mice...

Whilst there has been a reduction in the prevalence of peripheral vascular disease worldwide, a significant proportion of the world's growing population is still affected by disease of the aorta, carotid, iliac and lower limb arteries. These if left untreated can result in severe morbidity and mortality. However vascular surgery, the main definitive treatment for such conditions, is associated with subsequent injury to vital organs including the kidneys, heart, brain, intestines and lungs, with a consequent increase in both morbidity and mortality...
