Evaluation of the Space GlucoseControl System for Managing Stress-Induced Hyperglycemia in ICU Patients: Efficacy and Safety Assessment.

Abstract

Background: Despite the increasing adoption of the Space GlucoseControl system (SGCs), a novel blood glucose management technique, in critically ill patients, its efficacy and safety warrant further investigation.

Objective: This study aimed to assess the efficacy and safety of SGCs in managing patients with stress-induced hyperglycemia in the intensive care unit.

Methods: A prospective study was conducted involving 22 patients with stress-induced hyperglycemia monitored using the SGCs for 72 hours. Measurements included mean blood glucose, maximum blood glucose, minimum blood glucose, and frequencies of hyperglycemia (> 8.3 mmol/L), hypoglycemia (< 4.4 mmol/L), and target blood glucose (4.4 - 8.3 mmol/L).

Results: Mean blood glucose level was significantly different at 24 hours and 48 hours and 24 hours and 72 hours with SGCs (24h vs 48h, P=0.0289; 24h vs 72h, P=0.0252). The frequency of hyperglycemia (> 8.3 mmol/L) (24h vs 48h, P=0.0289; 24h vs 72h, P=0.0216) was significantly reduced at 48 hours and 72 hours compared to 24 hours. The mean interval between blood glucose measurements was significantly extended at 48 hours and 72 hours compared to 24 hours (24h vs 48h, P=0.0037; 24h vs 72h, P=0.0332). The frequency of target blood glucose (4.4 - 8.3 mmol/L) under SGCs blood glucose management at 48 hours and 72 hours was significantly higher than at 24 hours (24h vs 48h, P=0.0395; 24h vs 72h, P=0.0379). There was no significant difference in the frequency of hypoglycemia (< 4.4 mmol/L) and the maximum blood glucose values between 24 hours, 48 hours, and 72 hours with SGCs glucose management (P>0.05). These findings indicate that SGCs blood glucose management can promote greater stability in the blood glucose levels of patients and alleviate the workload of medical staff to some extent.

Conclusion: SGCs is effective in stabilizing blood glucose levels, increasing the frequency of target blood glucose values, and thereby reducing significant glucose fluctuations, which can improve patient recovery outcomes. Additionally, prolonged use of the SGC system not only optimizes glucose management but also significantly alleviates the workload of nursing staff, enhancing efficiency and allowing for more focused patient care.
