Insulin gastric acid secretion

This test is mainly used to estimate whether the effect after vagus nerve cutting is satisfactory. Insulin-injected gastric acid was positively increased by 20 mmol/L compared with BAO; the free acid increased by 10 mmol/L or more after injection of insulin was also positive; the positive vagus nerve that dominated the stomach was not completely cut within 45 minutes after injection of insulin. 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: BAO increased normally, suggesting that the gastric vagus nerve was not severed. Positive: Insulin-injected gastric acid was positively increased by 20 mmol/L compared with BAO; the free acid increased by 10 mmol/L or more after injection of insulin was also positive; the positive vagus nerve that dominated the stomach was not completely cut within 45 minutes after injection of insulin. Reminder: The patient's hypoglycemia response must be strictly observed during this test. Normal value After injection of insulin 0.15-0.2 U/kg, BAO increased by 5 or more than 20 mmol/L. Clinical significance 1. BAO rises normally: the gastric vagus nerve is not cut. 2, BAO increased by 1 ~ 5mmol / h: partial removal of gastric vagus nerve. 3, BAO increased <1mmol / h: gastric vagus nerve completely removed. Positive results may be diseases: duodenal ulcer precautions 1. The results of the test can be affected by factors such as spirit, gender, alcoholism and appetite. 2. The patient's hypoglycemia response must be strictly observed during this test. Patients with heart, brain, vascular disease and severe heart and lung dysfunction should be contraindicated in this test. Inspection process After the basal gastric juice was taken, the insulin was injected according to the body weight, and the gastric juice was taken 1 hour after the stimulation (four bottles were dispensed in the 15th minute) to determine the gastric acid secretion amount for 1 hour. Not suitable for the crowd Patients with heart, brain, vascular disease and severe heart and lung dysfunction should be contraindicated in this test. Adverse reactions and risks Hypoglycemia reaction: hypoglycemia can be induced after insulin injection, and the dosage should be strictly limited and monitored.
