BACKGROUND A novel double-lumen endotracheal tube, the Papworth BiVent tube, has been designed to allow the rapid passage of a blocker into either main bronchus, without fibreoptic endoscopic guidance. METHODS The feasibility of lung isolation and one-lung ventilation (OLV) in human cadavers is examined, along with displacement of the bronchus blocker during head and neck movement. RESULTS ...

OBJECTIVE The present study aimed to investigate the vocal tract and glottal function during and after phonation into a tube and a stirring straw. METHODS A male classically trained singer was assessed. Computerized tomography (CT) was performed when the subject produced [a:] at comfortable speaking pitch, phonated into the resonance tube and when repeating [a:] after the exercise. Similar pr...

The placement of nasogastric (NG) tubes is an extremely common intervention in general surgical wards and intensive care units. We report a case series of two patients who developed life threatening complications from the insertion of nasogastric tubes. Case 1 was a 71 year old man admitted to the Intensive Care Unit with pancreatitis who had three isolated complications from NG tube insertion....

BACKGROUND Poor positioning of an endobronchial double lumen tube (DLT) could affect oxygenation during one lung ventilation (OLV). We set out to relate DLT position to hypoxaemia and DLT misplacement during OLV. METHODS We recruited 152 ASA physical status I-II patients about to have elective thoracic surgery. The trachea was intubated with a left-sided DLT. Tube position was assessed by fib...

A new apparatus for attosecond time-resolved photoelectron spectroscopy of liquids and gases is described. It combines a liquid microjet source with a magnetic-bottle photoelectron spectrometer and an actively stabilized attosecond beamline. The photoelectron spectrometer permits venting and pumping of the interaction chamber without affecting the low pressure in the flight tube. This pressure ...

A 25-year-old woman was diagnosed with a ruptured ectopic pregnancy. During laparoscopic surgery, the patient was in the Trendelenberg position (20° degrees). Massive froth in the endotracheal tube was observed at the end of surgery. A portable chest x-ray, checked at the end of the operation, showed diffuse haziness in both upper lung fields. After one hour of aggressive treatment with drugs a...

EDITOR: Ventilatory problems during surgery in the prone position may be a serious complication [1]. We report an incident where there was dissection of a reinforced endotracheal tube that led to its partial obstruction. This case shows an unexpected complication from reusing products intended for single use. A 62-yr-old female (weight 68 kg) who was scheduled for total laminectomy with posteri...

Detectors with cross strip anodes have been used in open face and sealed tube detectors for detection of particles and light. In combination with high resolution position encoding electronics these have the capability of being able to independently record the accurate time and position of each detected photon event. Sealed tube (18 mm) microchannel plate cross strip anode detectors with superge...

Introduction Confirming the position of Nasogastric tubes (NGT) in critical care is a controversial area. The National Patient Safety Agency (NPSA) guidance [1] advocates pH testing although use is limited in ICU due to continuous enteral feeding and proton pump inhibitor therapy. Chest X-ray is therefore commonly used with trainee doctors often being responsible for confirming tube position. F...

We present an interactive audio game designed around the auditory perception of distance and the use of physics-based models for simulations of the dynamics, the sound source, and the acoustical environment. The game consists in throwing a virtual sounding object inside a virtual open-ended tube which is inclined. The task is to keep the object inside the tube, in other words the user should ad...
