Insulin treatment regimens include initiation regimens and intensive regimens. Today, we will focus on the intensive treatment regimen. Intensive insulin treatment regimen Intensive insulin treatment regimen I – Indications: 1. Patients whose blood glucose control does not meet the standard (HbA1c>7%) after combined treatment with basal insulin and oral medication. 2.Patients who need meal time flexibility. 3.Patients whose blood glucose control does not reach the standard (HbA1c>7%) even after basal + one additional mealtime insulin treatment. 4. Patients whose blood glucose control still does not reach the standard (HbA1c>7%) on the basis of premixed insulin therapy or who have recurrent hypoglycemia. Intensive insulin therapy program II – program: short-acting/quick-acting insulin before three meals + medium-acting/long-acting insulin at bedtime. 1. Blood glucose monitoring: monitor blood glucose before three meals, 2 hours after meals and at bedtime. 2.Efficacy assessment: HbA1c monitoring after three months and six months. Insulin Intensive Therapy Program III – Insulin Adjustment Program: 1.Adjust the bedtime intermediate-acting/long-acting insulin dosage according to fasting and 0:00-3:00 point blood glucose. 2.Adjust the insulin dosage before three meals according to the blood glucose levels before breakfast, lunch, dinner and bedtime. 3.Usually adjust the insulin dosage related to the highest pre-meal blood glucose value first, adjust the insulin dosage according to the pre-meal blood glucose first, and then adjust the pre-meal insulin dosage according to the post-meal blood glucose if all pre-meal blood glucose meets the standard. 4.Adjust once every 3-5 days, adjust 1 to 2 time points of blood glucose each time, and adjust the dose of 1 to 4 units each time according to the blood glucose level until the 4 points of blood glucose reach the standard.
