acid reflux test

The acid reflux test is a good way to test gastroesophageal reflux disease and esophageal hiatal hernia. Basic Information Specialist classification: Digestive examination classification: biochemical examination Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Normal value: no Above normal: negative: When the pH is correct, the pH value in the stomach is 1 to 4, and the pH in the esophage in the high pressure area is 5 to 7. Positive: pH Tips: Fasting a few hours before the check. Normal value When the pH is correct, the pH value in the stomach is 1 to 4, and the pH in the esophage in the high pressure area is 5 to 7. Clinical significance Abnormal results: pH<4 lasted for more than 5min and was positive. Need to check the crowd: gastroesophageal reflux disease, patients with hiatal hernia. Positive results may be diseases: considerations for gastroesophageal reflux disease Taboo before the test: fasting a few hours before the test. Taboo when checking: 1. Pull slowly when using the electrode and insert the electrode. 2. The method should be appropriate. Inspection process Inject 0.1 mol/L HCL 150-300 ml into the stomach and slowly pull the electrode. The electrode was placed 5 cm above the lower esophageal high pressure zone. The pH values ​​at different points of 5, 10 and 15 cm were measured. At the same time with the Valsala technique (the glottis is closed for exhalation to increase the intrathoracic pressure) and Muller's technique 9 after exhaling, close the sound and inhale, increase the intrathoracic negative pressure and change the position, induce gastroesophageal reflux, and measure the pH value. . Not suitable for the crowd Not suitable for the crowd: no. Adverse reactions and risks No related complications and hazards have been found.
