Effects of dexmedetomidine and propofol on lower esophageal sphincter and gastroesophageal pressure gradient in healthy volunteers.
BACKGROUND Many anesthetics reduce lower esophageal sphincter pressure (LESP). Reduced pressure and consequent reduction in the gastroesophageal pressure gradient (GEPG) thus promotes gastroesophageal reflux and may contribute to aspiration pneumonia and associated morbidity. Therefore, the authors compared LESP and GEPG during dexmedetomidine and propofol sedation. METHODS Using a randomized...
متن کاملLeg raise increases pressure in lower and upper esophageal sphincter among patients with gastroesophageal reflux disease.
The purpose of this study was to determine the relation between posturally increased intra-abdominal pressure and lower/upper esophageal sphincter pressure changes in patients with gastroesophageal reflux disease. We used high resolution manometry to measure pressure changes in lower and upper esophageal sphincter during bilateral leg rise. We also examined whether the rate of lower and upper e...
متن کاملEffect of ginger on lower esophageal sphincter pressure.
OBJECTIVE Ginger has been traditionally used to reduce intestinal gas and flatulence. The present study examined the effects of ginger on the esophagus and lower esophageal sphincter (LES) function by esophageal manometry. STUDY DESIGN A randomized controlled trial. SETTING Departments of Physiology and Medicine, Faculty of Medicine Siriraj Hospital. SUBJECTS Fourteen healthy young male v...

متن کاملMechanics of sphincter action. Studies on the lower esophageal sphincter.
The purpose of this study was to evaluate the mechanical factors involved in the genesis of lower esophageal sphincter pressure. We determined the relationship between intraluminal pressure and inside diameter, estimated the ratio between the wall thickness to inside radius, and calculated the tension in the wall of the lower esophageal sphincter as a function of the inside diameter. Various de...
