The Rotary-Draw Bending (RDB) process is a distinguished process employed for the precision cold bending of a hollow tube with small radius bends using Numerical Control (NC) machines. This research presents an analytical model based on the power law hardening model for the RDB processing of rectangular thin tubes. Based on the constraints of the tube in the dies and its thinness, the plane str...
impact on VAP. Second, we disagree with the opinion that the orientation of the endotracheal tube below horizontal will result in reduced incidence of VAP for the reason that it is based on insufficient clinical data: three experimental animal (sheep) studies, a randomized controlled trial with 60 ventilated infants that compared the tracheal colonization rate and not the VAP incidence in supin...
The LMA Supreme is a new extraglottic airway device which brings together features of the LMA ProSeal, Fastrach and Unique. We test the hypothesis that ease of insertion, oropharyngeal leak pressure, fibreoptic position and ease of gastric tube placement differ between the LMA ProSeal and the LMA Supreme in paralysed anesthetised patients. Ninety-three females aged 19-71 years were studied. Bot...
for replacement of a percutaneous endoscopic gastrostomy (PEG) tube. He had originally undergone PEG tube placement at our hospital 2 years ago, and after insertion the position of the hub had been checked by gastroscopy. However, placement of the most recent PEG tube had been done at another hospital 1 year ago, with no gastroscopic evaluation. When the patient attended our hospital 1 year lat...
BACKGROUND Aims of this study were to assess the maximum displacement of tracheal tube tip during head-neck movement in children, and to evaluate the appropriateness of the intubation depth marks on the Microcuff Paediatric Endotracheal Tube regarding the risk of inadvertent extubation and endobronchial intubation. METHODS We studied children, aged from birth to adolescence, undergoing cardia...
PURPOSE When tracheal intubation is required in a patient with an uncollapsible tracheal stenosis, the tip of the tube is usually positioned proximal to the stenosis. Only the tip of the tube may be in the trachea and the tube can be dislodged. We report the successful airway management of a patient with an uncollapsible tracheal stenosis who underwent cranial surgery in the prone position. C...
PURPOSE To limit the side effects of interventional neuroradiologic radiation, such as epilation, by applying a technique involving tube position rotation and by adding a supplemental inexpensive primary beam filter; and to show the dose effect of modifying technical factors. METHODS Combined skin dose from fluoroscopy and digital subtraction angiography was measured with an array of 16 therm...
