Effect of insulin pump and continuous intravenous insulin on ketone body metabolism, blood gas indexes and stress state in patients with diabetic ketoacidosis

摘要

Objective:To study the effect of insulin pump and continuous intravenous insulin on ketone body metabolism, blood gas indexes and stress state in patients with diabetic ketoacidosis. Methods:Patients with diabetic ketoacidosis who were treated in Meizhou Maternal and Child Heath Hospital between May 2014 and March 2017 were selected as the research subjects and randomly divided into the group A who received subcutaneous insulin infusion by insulin pump and the group B who received intravenous small-dose insulin injection by micropump. The indexes of ketone body, blood gas and stress were measured before and after treatment. Results: 12 h and 24 h after treatment, serumβ-hydroxybutyrate, MDA, NE, ACTH and Cor contents of both groups of patients were significantly lower than those before treatment while pH, HCO3- and base excess levels as well as serum SOD, GSH-Px, CAT and TAC contents were significantly higher than those before treatment, and serumβ-hydroxybutyrate, MDA, NE, ACTH and Cor contents of group A were significantly lower than those of group B while pH, HCO3- and base excess levels as well as serum SOD, GSH-Px, CAT and TAC contents were significantly higher than those of group B.Conclusion:Subcutaneous insulin infusion by insulin pump can improve ketone body metabolism, acidosis status and stress state in patients with diabetic ketoacidosis.
