Physiological insulin supply regimen i.e. 3 to 4 injections/day (intensive treatment regimen). 1.Quick/short-acting insulin injections before three meals + medium/long-acting insulin injections at bedtime, 4 times/day. 2.Quick/short-acting insulin injection before three meals, 3 times/day. 3.Injections of rapid/short-acting insulin before breakfast and dinner + oral hypoglycemic medication before lunch + medium/long-acting insulin before bedtime, 3 times/day. 4.Inject premixed insulin before breakfast + inject rapid/short-acting insulin before night toluene + inject medium/long-acting insulin before bedtime, 3 times/day. 1～2 times/day insulin injection (non-intensive treatment regimen) ① BIDO treatment regimen: medium/long-acting insulin injection before bedtime + oral hypoglycemic drugs during the day. Including: the original treatment regimen remains unchanged, and 1 time of medium and long-acting insulin is added in the evening or oral hypoglycemic drugs are reduced. Add 1 insulin in the evening, such as sulfonylureas alone + insulin (economic, practical, and exact efficacy, but weight gain and hypoglycemia may occur); biguanides or glucosidase inhibitors + insulin (weight gain is not obvious, can reduce insulin resistance, but the efficacy is poor, and hypoglycemia is easy to occur when the insulin dose is increased); add the above or add insulin sensitizers alone; stop sulfonylureas, other medications remain unchanged, and insulin is used ≥2 times a day. The insulin pump insulin subcutaneous continuous injection method simulates the physiological secretion of insulin, that is, continuous subcutaneous injection of short-acting insulin to maintain the basal insulin level, and subcutaneous injection of high-dose insulin before meals to control postprandial blood glucose, while the dose of insulin can be adjusted at any time to achieve good control of blood glucose level, while avoiding the occurrence of hypoglycemia, which is the most effective measure for intensive treatment of diabetic patients and can obtain more It is the most effective measure of intensive treatment for diabetic patients, which can achieve more ideal blood glucose control. Its indications include: type 1 diabetes, type 2 diabetes with secondary failure of sulfonylurea, severe undetectable (asymptomatic) hypoglycemia, gestational diabetes, very insulin-sensitive diabetes (<20 u/day or 0.4u/kg), severe dawn phenomenon, chronic complications of diabetes, acute complications of diabetes (such as ketoacidosis), newly diagnosed type 2 diabetes, diabetes requiring surgery patients, and those who need more social activities. Calculation of the initial daily dose: Calculation based on body weight (not yet using insulin), 1 day total = body weight × 0.44; Calculation based on the dosage before using the pump (blood sugar control is still possible), 1 day total = insulin dosage before using the pump × (75% to 80%).
