Rechecking the position of the nasogastric tube after oropharyngeal suction is not common practice. Our patient deteriorated after oropharyngeal suction was performed, whilst nasogastric feeding continued. We suggest that nasogastric feeding should be stopped during oropharyngeal suction and the tube position should be checked every time an oropharyngeal suction is performed.

We measured directly mucosal pressures against the cuff and non-cuff portions of the tracheal tube in different head-neck positions and tested the reliability of calculated mucosal pressures, in vivo intracuff pressures and cuff volume as determinants of directly measured mucosal pressures. We studied 10 anaesthetized, paralysed adult patients. An 8.5-mm, high volume, low pressure PVC tracheal ...

this study aims to numerically investigate on the crashworthiness of thin-walled square tubes by consideration of 3-d oblique loading. in this type of loading, direction of loading is defined by using two spatial angles relative to the position of the tube. to this aim, finite element (fe) analysis is employed to simulate the loading for 8 different numerical models with different loading orien...

Ensuring that the distal end of an endotracheal tube is properly located within the trachea, and that the tube is not obstructed by mucous deposition, is a major clinical concern. This concern is heightened in infant care, where the relatively small geometries predicate higher risks. A novel acoustic system was developed to allow for the continuous monitoring of endotracheal tube position and p...

We read with great interest the recent report on blind bedside postpyloric placement by Lv et al. [1]. Their methods were proven to be safe and effective in intensive care units. Although our placing procedure is similar to that reported by the authors, the choice of a postpyloric tube and the patient’s position requires further improvement. In our center, we use a 130-cm long transpyloric tube...

objectives: the aim of this study was to assess the effect of tube current, kilovoltage peak (kvp), metal type, and the position of metal objects on metal artifacts in cone-beam computed tomography (cbct) images. materials and methods: titanium and cobalt-chromium rods were fabricated and placed in a dry human mandible. samples were scanned using a promax 3d cbct unit with different milli-amper...
