BACKGROUND: Retinal ischemia/reperfusion (I/R) injury is one of significant cause of visual dysopia and causes inflammatory response. Dexmedetomidine is widely applied to general/local anaesthesia and has been reported to have extensive anti-inflammatory effect. However, the role of dexmedetomidine in retinal I/R injury is currently unknown. This study investigates the effect of dexmedetomidine preconditioning on retinal I/R injury and explore the related signal mechanism toll-like receptor 4 (TLR4) pathway...

We propose a multi-pinhole fluorescent x-ray computed tomography (mp-FXCT) technique for preclinical molecular imaging that can provide the complete data necessary to produce 3-D tomographic images during anaesthesia. In this method, multiple projections are simultaneously acquired through a multi-pinhole collimator with a 2-D detector and full-field volumetric beam to accelerate the data acquisition process and enhance the signal-to-noise ratios of the projections. We constructed a 15-pinhole mp-FXCT imaging system at beamline ARNE-7A at KEK and performed preliminary experiments to investigate its imaging properties using physical phantoms and a non-radioactive I imaging agent...

: The anaesthetic management of patients with myopathies is challenging. Considering the low incidence and heterogeneity of these disorders, most anaesthetists are unfamiliar with key symptoms, associated co-morbidities and implications for anaesthesia. The pre-anaesthetic assessment aims at the detection of potentially undiagnosed myopathic patients and, in case of known or suspected muscular disease, on the quantification of disease progression. Ancillary testing (e.g. echocardiography, ECG, lung function testing etc...

BACKGROUND: Spinal anaesthesia is technique of choice for caesarean sections and hyperbaric bupivacaine is a recommended drug for this popular block. Although safe but few complications are haemodynamic changes, postdural puncture headache, cauda equina syndrome and radiculopathy. However, hypotension remains the common side effect which is believed to occur in 95% of patients resulting in reduction of uteroplacental perfusion causing foetal acid-base abnormalities. Various doses regimes are in safe anaesthesia practice for providing regional anaesthesia for such patients with least detrimental effects on foetal outcome...

OBJECTIVE: A local anaesthetic with fast onset, short and reliable duration of anaesthesia may be preferable for day care urological surgeries. Low dose lignocaine is believed to act faster and to have a shorter duration of action than low dose bupivacaine. Use of lignocaine for spinal anesthesia is discouraged now a days because of rare reports of transient neurological symptoms. The purpose of this study was to compare effectiveness and safety of low dose of lignocaine + butorphanol against low dose of bupivacaine for day care urological surgeries...

PURPOSE: Maxillofacial deformities are always psychologically and physically distressing to the patients and is also challenging to the treating surgeons. The term Micrognathia means a "small jaw". True micrognathia, where the maxilla or the mandibular skeleton does not grow to the full size can be congenital or acquired. Distraction osteogenesis also called as callus distraction or callostasis or osteodistraction or distraction histogenesis is a biological process of regenerating newly formed bone and adjacent soft tissue by a gradual and controlled traction of surgically separated bone segments...

BACKGROUND: Propofol is a widely-accepted medication for the successful insertion of laryngeal mask airway (LMA). When propofol is used alone, larger doses are required which can lead to cardiorespiratory distress resulting in hypotension and prolonged apnoea. The objective of this study was to evaluate the effect of premedication of midazolam on different doses of propofol for LMA insertion. METHODS: In this randomized clinical trial, eighty-six (86) patients who were scheduled to undergo elective surgery is supine position not requiring the need for tracheal intubation from September 2015 to 6 March 2016 were included...

PURPOSE OF REVIEW: With the prevalence of obesity rapidly growing, bariatric anaesthesia becomes everyday anaesthesia rather than a subspecialty. In this review, we are aiming to draw attention to this complex group of patients and their comorbidities, relevant to everyday practice for contemporary anaesthetists. RECENT FINDINGS: We wanted to focus greatly on sleep-related breathing disorders, because preoperative screening, diagnosis and treatment of the aforementioned make a huge impact in the improvement of preoperative morbidity and mortality, including positive effects on the cardiovascular system...

Botulinum intramuscular injections are increasingly being used in the management of hypertonic musculature. Historically, injections were administered under general anaesthesia (GA), which has service and economic implications. Our delivery changed to outpatient conscious injections to improve service efficiency. A retrospective analysis of all patient injections from January 2010 to December 2015 analysed cost-benefit and efficiency of service remodelling. 472 patients were administered injections, 298 in theatre under GA and 174 without GA...
