UNLABELLED Lung isolation can be accomplished in two ways: the first, a double-lumen endotracheal tube (DLT) and the second, a bronchial blocker (Univent or Arndt blocker). Previous studies have found that the DLT and the Univent are comparable when providing lung isolation. A new bronchial blocker, the wire-guided endobronchial blocker (Arndt blocker), has been introduced. However, there is no...

Abstract A novel buckling-induced forming method is proposed to produce metal bellows. The tube billet firstly treated by local heating and cooling, the axial loading applied on both ends of tube, then buckling occurs at designated position forms a convolution. In this paper, apparatus designed developed discontinuous continuous bellows 304 stainless steel, their characteristics are discussed r...

This paper describes the small-diameter monitored drift-tube detector construction at University of Michigan as a contribution to ATLAS Muon Spectrometer upgrade for high-luminosity Large Hadron Collider CERN. Measurements first 30 chambers built show that drift tube wire position accuracy meets specification 20 microns. The positions platforms alignment and magnetic field sensors are all insta...

Abstract Recent advances in treatment for esophageal cancer have improved prognosis after esophagectomy, but they led to an increased incidence of gastric conduit cancer. In most patients who underwent retrosternal reconstruction, median sternotomy is performed, which associated with a risk postoperative bleeding and osteomyelitis; pain often negatively affects respiration. To avoid these probl...

Numerical investigation was performed on a semi-model (one stay vane, two guide vanes, one runner passage inclusive of main and splitter blade, the draft tube) high-head Francis turbine model with adjustable vanes in tube. The motive present study is to investigate possibility mitigate rotating vortex rope (RVR) formed at part load operating condition. Each vane tube consists hydrofoils. upper ...

OBJECTIVE To compare ultrasonography with chest radiograph to detect the level of endotracheal tube tip in intubated neonates. DESIGN Observational. SETTING Neonatal care unit of a teaching hospital. PARTICIPANTS 53 neonates selected by convenience sampling. INTERVENTION Ultrasonography of chest was done with probe of 5 to 8 MHz using high parasternal view. The distance of the endotrach...

INTRODUCTION Nasojejunal feeding tube placement can be achieved by fluoroscopic or endoscopic techniques. Significant complications due to nasojejunal feeding tube placement, such as hydrothorax, duodenal perforation and retroperitoneal emphysema, are very rare. We present a case of massive retroperitoneal emphysema and abscess because of duodenal perforation caused by a kink in a nasojejunal f...

A new percutaneous insertion technique for esophageal feeding tubes in cats is presented. The technique has been successfully applied in 12 feline patients. The placement technique is relatively simple, takes approximately five minutes to perform, and requires a scalpel blade, a curved hemostat, and an applicator for the insertion of the feeding tube. In contrast to other esophageal tube placem...
