ph metria

Is demonstrated current information about the nature and method of computing the 24-hour pH-metria of the esophagus and stomach, as well as the Interpretation acidification (acidification) of the gastrointestinal tract.

UNLABELLED: Studying role of duodenogastric reflux (DGR) in pathogenesis and sanogenesis of duodenal ulcer (DU). MATERIAL AND METHODS: 233 DU patients (92 patients with a mild, 45--with modern and 96--with the complicated current of disease) are surveyed. Control group were 100 healthy volunteers. Clinical research, endoscopy and 24-hours pH-metria was carried out. In a year after eradication Helicobacter pylori (Hp) 30 patients are repeatedly surveyed. RESULTS: at healthy acidity more low, and DGR above and more for a long time, than at DU patients...

UNLABELLED: The neutralization of gastric content during feeding and in the immediate postpandrial period, has determined that until recently time these periods were excluded in the studies of the gastroesophageal reflux disease (GERD) that were made with pH-metría. The aim of this study was to characterize the events of reflux during feeding with pH and impedance,and later to compare them with which it happens in fasting periods. MATERIAL AND METHOD: We recording pH and Impedance in 21 preterms neonates without associated pathology, except the prematurity, during 8 periods of feeding-fasting (1 hour of feeding and 2 hours of rest), replacing the nasogastric tube by a catheter of feeding + impedance, previous informed consent...
