Analysis of Pentagastrin Gastric Fluid

The fasting gastric juice was exhausted and discarded, and then the gastric juice was continuously extracted for 1 hour, and the gastric juice volume was measured to be the basic gastric acid volume. After the measurement, the pentagastrin was injected subcutaneously or intramuscularly per kilogram of body weight, and gastric juice was extracted once every 15 minutes for a total of 4 times. The amount of gastric juice was recorded, the acidity was measured, and the results of the 4 titrations were added to obtain a maximum of 1 h. The amount of gastric acid, which is the sum of two consecutive highest acid amounts multiplied by 2 is the peak gastric acid amount. Normal people are affected by many factors such as nerves and endocrine, have large variation, and have poor repeatability.
