ABSTRACT

Objective To observe hypoglycemic efficacy of continuous glucose monitoring system (CGMS)combined with continuous insulin infusion(CSII)in the elderly diabetic patients aged 60 years and over.Methods A total 0f 100 elderly diabetic patients were randomly divided into two groups.50 were treated with CGMS or self-monitoring blood glucose(SMBG)and CSII.and whose insulin dose was adjusted based on results of monitoring,and the other 50 with SMBG and insulin pump as controls.whose insulin dose was adiusted based on the results of SMBG for three days.After two weeks.all the patients were monitored by CGMS for blood glucose.Results Mean blood level of glucose and mean amplitude of glycemic excursions(MAGE)were significantly lower in CGMS+CSII group than those in controls[(6.6±2.3)mmol/L vs.(7.5±2.1)mmol/L,and(3.9±0.9)mmol/L vs.(5.1±0.6)mmol/L,respectively,P＜0.05 1.Average insulin dose used was significantly lower in CGMS+CSII group than that in controls [(0.64±0.21)U/kg vs.(0.82±0.41)U/kg,P＜0.05],and duration of hypoglycemia was less in the former than that in the latter[(20±3)min vs.(40± 9)min,P＜0.05 ].Conclnsions CGMS combined with CSII can decrease blood glucose.glucose excursions.average dose of insulin and duration of hypoglycemia in the elderly diabetic patients,as well as prevent occurrence of hypoglycemia.
