The ratio of proportional sugar water to insulin is generally configured in a 4:1 manner, that is, 4g of glucose needs to be matched with 1U of insulin, such as 5% of glucose 500mL, and 6U of insulin is used for routine clinical rationing. However, this is only the conventional usage, but nowadays, the emphasis is on individualized medication in the treatment of diabetic patients, so it is better to determine the patient’s personal situation when preparing, such as the current blood glucose level, the insulin added to different blood glucose levels is different, if the patient’s measured blood glucose value is higher, the insulin to be mixed into the ratio of glucose as the rationing solution should be higher, the ratio of glucose injection to insulin can be mentioned as 3:1, that is, 5% glucose The ratio of glucose injection to insulin can be mentioned as 3:1, that is, 5% glucose to 500mL, and 8U insulin can be mixed in when using. If the patient’s blood glucose level is very high or insulin resistance exists, then the ratio of insulin to sugar water may be increased up to 2:1. If the patient’s blood glucose value is measured to be low or the patient is sensitive to insulin action, less insulin should be mixed in.
