Intravenous insulin is usually prepared with a ratio of glucose to insulin of about 4-6:1. When diabetic patients have to use glucose injection solution as solvent, clinics usually adopt the addition of insulin to neutralize glucose, generally the ratio of glucose to insulin is about 4-6:1, such as adding 2-3 units of insulin into 250 ml of 5% glucose injection solution. Intravenous insulin drip advocates individualized medication, adding different amounts of insulin for patients with different blood glucose levels. Patients with high blood glucose have more insulin in their sugar drops. For patients who have never applied insulin, the addition of insulin within the first bottle of glucose should be conservative, with blood glucose measured once an hour and additional insulin added if blood glucose drops slowly. Excessive insulin can make blood glucose too low, which can lead to hunger, rapid pulse, dilated pupils, dizziness, ataxia, tremor anxiety, mental restlessness, coma, and even convulsions. It is recommended that intravenous fluids be dispensed under medical supervision.
