About

In this study, we plan to use an open-source hybrid closed-loop artificial pancreas system and a combination of a traditional insulin pump and continuous glucose monitoring (CGM) respectively to conduct short-term intensive insulin treatment for patients with type 2 diabetes mellitus (T2DM) during the perioperative period who are hospitalized in the Department of Neurosurgery of Shanxi Bethune Hospital. By comparing the blood glucose control status of patients under different intensive insulin treatment regimens and other clinical indicators such as postoperative complications, we will comprehensively evaluate the clinical efficacy and safety of the hybrid closed-loop artificial pancreas system.

Full description

According to the inclusion and exclusion criteria, 40 perioperative patients with type 2 diabetes mellitus (T2DM) will be screened and enrolled from the neurosurgical ward of Shanxi Bethune Hospital. They will be randomly divided into two groups: 20 patients in the hybrid closed-loop artificial pancreas system group and 20 patients in the traditional pump combined with continuous glucose monitoring (CGM) group. Both groups of patients will use continuous glucose monitoring to measure blood glucose levels. After collecting baseline data, the two groups of patients will receive short-term intensive insulin therapy according to the above-mentioned plans. Relevant clinical data will be collected during and after the treatment to compare the advantages and disadvantages of the two intensive insulin treatment plans in controlling blood glucose levels in perioperative T2DM patients undergoing neurosurgery and their impact on complications.

40 participants in 2 patient groups, including a placebo group

Traditional insulin pump group
Placebo Comparator group
Description:
Based on the patient's weight, the total daily insulin requirement is calculated at 0.3\~0.6U/(kg\*d) and distributed before meals according to the specific conditions of the patient. Continuous glucose monitoring system is used along with daily capillary blood glucose monitoring (fasting, 2 hours after breakfast, lunch, and dinner, totaling 4 times). Insulin doses are adjusted according to the patient's blood glucose level until the target blood glucose level is achieved.
Treatment:
Device: Hybrid Closed-Loop Artificial Pancreas System
Hybrid Closed-Loop Artificial Pancreas System Group
Experimental group
Description:
The open-source hybrid closed-loop artificial pancreas system, utilizing ultra-rapid-acting insulin, was employed for perioperative blood glucose management in neurosurgery. Insulin requirements were calculated based on patient weight. The system auto-adjusted basal rates according to blood glucose, while bolus treatments were manually inputted by nurses following physician instructions. Continuous and daily capillary blood glucose monitoring were conducted.
