J J Moser, A M Walker, A O Spencer
Background: Gastric sonography is emerging as a valuable clinical point-of-care tool to assess aspiration risk. A recent study proposed that a single cut-off cross-sectional area (CSA) in the supine position could diagnose an empty stomach in the parturient. This study establishes the sensitivity and specificity of a single CSA cut-off measurement in both supine and right lateral decubitus (RLD) positions in the diagnosis of an empty antrum in paediatric patients. Methods: Following induction of anaesthesia, antral sonography was performed in supine and RLD positions in 100 fasted paediatric patients prior to upper endoscopic evaluation...

It has been shown experimentally that cratered surfaces may have better adhesion properties than flat ones. However, the suction effect produced by the craters, which may be chiefly responsible for the improved adhesion, has not been properly modelled. This paper combines experimental, numerical simulation and analytical approaches towards developing a framework for quantifying the suction effect produced by isolated craters and cratered surfaces. The modelling approach emphasizes the essential role of large elastic deformation, while the airflow dynamics, microscopic mechanisms, like surface tension and air permeation, and rate-dependence are neglected...

A new portable gas phase nitric oxide (NO) generator is described for potential applications in inhaled NO (INO) therapy and during cardiopulmonary bypass (CPB) surgery. In this system, NO is produced at the surface of a large area mesh working electrode by electrochemical reduction of nitrite ions in the presence of a soluble copper(II)-ligand electron transfer mediator complex. The NO generated is then transported into gas phase by either direct purging with nitrogen or via circulating the electrolyte/nitrite solution through a gas extraction silicone fiber-based membrane-dialyzer assembly...

Dysfunction of the colonic sensory nerves has been implicated in the pathophysiology of several common conditions, including functional and inflammatory bowel diseases and diabetes. Here, we describe a protocol for the in vitro characterization of the electrophysiological properties of colonic afferents in rats. The colorectum, with the intact pelvic ganglion (PG) attached, is removed from the rat; superfused with carbogenated Krebs solution in the recording chamber; and cannulated at the oral and anal ends to allow for distension...

CONTEXT: Myocardial injury during cardiac surgery on cardiopulmonary bypass (CPB) is a major determinant of morbidity and mortality. Preclinical and clinical evidence of dose- and time-related cardioprotective effects of volatile anesthetic drugs exist and their use during the whole surgery duration could improve perioperative cardiac protection. Even if administering volatile agents during CPB are relatively easy, technical problems, such as waste gas scavenging, may prevent safe and manageable administration of halogenated vapors during CPB...

Dalbir S Sandhu, Ye J Lee, Henning Gerke
BACKGROUND AND AIMS: Large sessile/flat colonic polyps are traditionally removed by lift polypectomy. Underwater endoscopic mucosal resection (UEMR) is a novel technique where air is suctioned out and replaced by water to decompress the colon so that the flat lesions assumes a more polypoid shape facilitating its removal with the standard snare resection. We report the feasibility and safety in our series of patients utilizing this technique. PATIENTS AND METHODS: A retrospective, observational study of all patients who underwent removal of large colonic polyps (>10 mm) over a period of 3 years (January 2012 - January 2015) at a tertiary care center by UEMR were included in the study...

Self-made devices composed of agar and gelatin gel have been used for resident training of intra-axial brain tumor resection. The mixture gel of agar and gelatin is retractable and can be suctioned. Hardness of the gel depends on the concentration of the solution. Therefore, by changing the concentration, it is easy to make gels of various hardness. In this study, a mass of gel that looked like a tumor was put into another gel that looked like the brain. A part of the "brain" was regarded as the eloquent area...

Ventilator-associated pneumonia (VAP) is a potentially preventable iatrogenic illness that may develop following mechanical ventilation. A bundle for the prevention of VAP consists of different measures which may vary between institutions, and may include: elevation of the head of the bed, oral care with chlorhexidine, subglottic suctioning, daily assessment for extubation and the need for proton-pump inhibitors, use of closed suction systems, and maintaining endotracheal cuff pressure at 25 cmH2O. Our aim was to determine the efficacy of a VAP prevention bundle, consisting of the above-mentioned measures, by evaluating the incidence of VAP before (no-VAP-B group) and after (VAP-B group) the introduction of the bundle...
