Closed Loop

The incidence of type 1 diabetes is increasing, with an incidence of +4% per year in France today. The treatment for type 1 diabetes is insulin therapy. In recent years, new systems have emerged, so-called "semi-closed loop" systems, also called automated insulin therapy, which have proven their superiority in terms of quality of life and glycemic balance in adults and children over 6 years old. Since January 24, 2024, the HAS now recognizes the indication of the semi-closed loop for the YPSOPUMP model in children aged 2 to 6 years. This is the first reimbursement in France of a closed loop system for the 2-6 year old age group. There are currently few studies comparing the quality of life of children in semi-closed loop versus other treatments (open loop or injections). Regarding quality of life, the studies found mainly concern the contribution for parents and the improvement of adolescents' sleep as in the study by Erin C Cobry et al from 2020 (6). Our study therefore aims to demonstrate an improvement in quality of life but also in diabetes balance in type 1 diabetic patients on a closed loop insulin pump versus open loop or injections in the pediatric population aged 2-6 years.

The propofol-remifentanil closed-loop TCI system based on EEG guidance has been clinically verified, which enables more precise anesthetic dosing. As an adjunct to anesthesia, esketamine has been shown to stabilize hemodynamics, reduce opioid use, and reduce postoperative nausea and vomiting. However, due to its specific electroencephalographic excitatory effect, esketmine's clinical use in close-loop system has been limited. The aim of this experiment was to determine the specific impact of esketamine on EEG and thus obtain a new EEG baseline for close-loop system, which can broaden the application of close-loop TCI system in combination with other drugs.
