Plastic pH electrodes for the measurement of gastrointestinal pH.
Plastic electrodes have been developed for measuring pH in the human gastrointestinal tract. The electrodes have a plastic hydrogen ion sensitive membrane sealed to a length of fluid filled PVC tubing. Two recently developed hydrogen ion sensitive ligands have been examined. Their operational characteristics have been described. These electrodes have an electrical response of 52 to 58 mV/pH uni...
متن کاملSpontaneous migration of central venous catheter tip.
A 37 year old female diagnosed as a case of acute myeloid leukemia (AML) underwent allogenic stem cell transplant. A 12.5 French triple lumen Hickman's catheter was inserted via right internal jugular vein under fluoroscopic guidance. Post insertion X-ray confirmed desired position of the catheter tip (Fig. 1). Two days post insertion she developed mild pain in the nape of neck which increased ...
متن کاملOscillations in extracellular pH and reactive oxygen species modulate tip growth of Arabidopsis root hairs.
Root hairs show highly localized cell expansion focused to their growing tips. This growth pattern is accomplished through restriction of secretion to the elongating apex and modulation of cell wall properties, with the wall just behind the tip becoming rigidified to resist the lateral expansive forces of turgor. In this report we show that root hairs exhibit oscillating growth that is associat...
متن کاملTowards Optimal Central Venous Catheter Tip Position
Central venous catheters (CVCs) are required in many critically ill patients. As with most invasive procedures, central venous catheterisation is associated with numerous potential complications, many of which stem from the access procedure. Other serious complications are related to the catheter tip position. Secondary to CVC misplacement, there is significant morbidity and mortality associate...
متن کاملVenous pH can safely replace arterial pH in the initial evaluation of patients in the emergency department.
OBJECTIVE This study aims to determine the extent of correlation of arterial and venous pH with a view to identifying whether venous samples can be used as an alternative to arterial values in the clinical management of selected patients in the emergency department. METHODS This prospective study of patients who were deemed by their treating doctor to require an arterial blood gas analysis to...
