Basal gastric secretion

The amount of basal gastric acid secretion refers to the amount of gastric acid secretion for 1 hour without food or drug stimulation. Increased in duodenal ulcer Zollinger-Ellison syndrome (Zhuo-Ai syndrome), portal vein anastomosis, small bowel resection, carcinoid syndrome, severe central nervous system disease, pyloric obstruction, a small number of pancreatic diseases. Basic Information Specialist classification: Digestive examination classification: body fluid examination Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Atrophic gastritis, gastric cancer, pernicious anemia, hyperthyroidism, long-term alcoholism, subacute combined degeneration of the spinal cord, stomach gangrene, oral infection and suppuration. Normal value: Basal gastric secretion: 1.92-5..88mmol/h Above normal: Duodenal ulcer Zollinger-Ellison syndrome (Zhuo-Ai syndrome), portal vein anastomosis, small bowel resection, carcinoid syndrome, severe central nervous system disease, pyloric obstruction, a small number of pancreatic diseases. negative: Positive: Tips: Some patients with diseases are not suitable for this examination, such as esophageal stricture, esophageal varices, aortic aneurysm, severe hypertension, cardiovascular disease. Therefore, patients should tell their doctors their medical history in detail before deciding to do this test. Normal value Normal human basal gastric acid secretion (BAO) (3.9 ± 1.98) mmol / h, rarely more than 5mmol / h Clinical significance Abnormal result 1, elevated duodenal ulcer Zollinger-Ellison syndrome (Zhuo-Ai syndrome), portal vein anastomosis, small bowel resection, carcinoid syndrome, severe central nervous system disease, pyloric obstruction, a small number of pancreatic diseases. 2, reduce atrophic gastritis, gastric cancer, pernicious anemia, hyperthyroidism, long-term alcohol abuse, subacute combined degeneration of the spinal cord, stomach gangrene, oral infection and suppuration. People who need to be checked People who have been drinking for a long time have a good appetite but are getting thinner. Low results may be diseases: pyloric obstruction, high gastric cancer results may be diseases: duodenal ulcer, atrophic gastritis precautions Before inspection: 1. Some patients with diseases are not suitable for this examination, such as esophageal stricture, esophageal varices, aortic aneurysm, severe hypertension, cardiovascular disease, etc. Therefore, patients should tell their doctors their medical history in detail before deciding to do this test. 2, 2 days before the examination, stop using drugs that affect the secretion of gastric juice, such as ranitidine, sucralfate and so on. 3, because different diets have different effects on gastric juice secretion, so it is forbidden to eat high-protein, high-fat foods 24 hours before the test, and do not drink alcohol: water is forbidden for 12 hours before the test. When checking: 1, because mood swings will affect the secretion of gastric acid, so avoid mental stimulation before doing this test. 2, patients should not be nervous, should relax themselves, with the doctor's operation. Inspection process 1. On the day before the analysis of gastric juice, various drugs that affect the secretion of gastric juice, such as atropine and probensin, were stopped. Fasted and banned after dinner (12 hours). 2, check the morning on the fasting state, insert the stomach tube from the nostrils, when the stomach tube is inserted into the pharyngeal gorge, there will always be a feeling, at this time the patient has to take the active spring pharyngeal action, the operator will take the stomach tube into the esophagus. If you have a sense of care through the pharyngeal gorge, deep breathing can be alleviated. When the stomach tube enters the esophagus and enters a length of about 56 cm, the gastric juice can be withdrawn, indicating that it has reached the stomach cavity. If the nasal cavity has a disease that cannot be inserted, it can also be inserted through the mouth. 3. Drain the fasting stomach juice. Then, the gastric juice was continuously extracted for 1 hour, the gastric juice was kept in the container, and the gastric acid was measured and measured. The gastric juice is usually taken once every 15 minutes for 4 times. The sum of gastric acid is called the amount of basal gastric acid secretion, expressed as BAO. The normal value is less than 5mmo1/hour. 4, the use of stimulants, such as subcutaneous injection of histamine or subcutaneous injection of five gastrin. The gastric juice was then continuously aspirated, and the gastric juice was collected once every 15 minutes for 4 times. After the injection of the gastric acid stimulating agent, the total amount of gastric acid secretion collected four times in one hour is called the maximum gastric acid excretion. According to MAO, normal males were 18.02±8.84 mmo1/hour, and females were 13.43±7.98 mmo1/hour. The highest gastric acid output in two consecutive 15 minutes in 4 specimens was multiplied by 2, which is called the peak acid output, expressed as PAO. According to the application of the stimulant can be divided into 1 histamine test: subcutaneous injection of histamine phosphate 40 μg / kg body weight. 2 five gastrin test: the injection dose is 6 micrograms / kg body weight. Previously, a trial test was used, such as eating half a taro or two slices of bread and 400 ml of warm boiled water. Therefore, the method is not accurate and is not used now. 5, inspection: the gastric juice extracted at different times for related inspections, including general traits (color, taste, etc.), gastric acid determination, occult blood test, bacterial detection, tumor cells and other cell analysis. Not suitable for the crowd Some patients with diseases are not suitable for this examination, such as esophageal stricture, esophageal varices, aortic aneurysm, severe hypertension, cardiovascular disease. Adverse reactions and risks Generally no complications and harm.
