Résumé
Objective To investigate the effect of real-time continuous monitoring system(RT-CGMS)on serum inflammatory factors and prognosis in patients with sepsis.Methods According to the prospective studies,patients were randomly divided into two groups Patients with sepsis were randomly divided into real-time continuous monitoring of blood glucose group and monitoring blood glucose meter group,of which the fasting serum tumor necrosis factor alpha(TNF-α) and interleukin-6(IL-6) and high sensitive C reactive protein (hs-CRP) were detected on the 1st,3rd,7th day.Meanwhile,insulin dosage,incidence of hypoglycemia and mortality rate of 28 days of patients in two groups were recorded,and the above indexes were analyzed.Results TNF-α,IL-6 and hs-CRP in the real-time continuous blood glucose monitoring group were (16.12±2.42)pg/ml、(112.37±17.39)pg/ml and(19.62±2.72)mg/L on the 7th day respectively,while TNF-α,IL-6 and hs-CRP in the blood glucose monitoring group were(23.46±3.12)pg/ml、(140.19±21.48)pg/ml and(25.42±2.54)mg/L on the 7th day,respectively.The decrease of TNF-α,IL-6 and hs-CRP in the continuous blood glucose monitoring group was more significant than that in the blood glucose monitoring group (P＜0.05).Insulin dosage in real-time continuous blood glucose monitoring group was (90.62±15.79)u,hypoglycemia rate was 5.4％,fatality rate was 10.81％ in 28 days of hospitalization,insulin dosage was (130.59±20.65)u,hypoglycemia rate was 22.85％,and fatality rate was 31.42％ in 28 days of hospitalization.There was significant difference between the two groups(P＜0.05).Conclusion For sepsis patients with stress hyperglycemia,a real-time continuous monitoring system combined with insulin therapy can improve the inflammatory response,and control blood glucose effectively as well as reduce mortality.
Résumé
Objective To explore the feasibility of Guardian real-time continuous monitoring system (GRT) in high-risk infants with hypoglycemia.Methods The glucose of 72 infants admitted to Neonatal Intensive Care Unit (NICU) of Children's Hospital of Fudan University between May 2015 and December 2016 were detected by GRT (provided by Medtronic),there were 43 males and 29 females with gestational age [(35.25 ± 4.45) weeks],and birth weight [(2 385.69 ± 1 062.63) g].At the same time,the capillary glucose was monitored intermittently detected by using ACCU-CHEK(R).Results A total of 1 134 paired glucose levels were collected.A good correlation between the paired capillary[(5.23 ± 1.96) mmol/L] and GRT continuous monitor measurements [(5.19 ± 1.99) mmol/L] was found(r =0.88,P ＜ O.05),and the value of mean absolute difference (MAD) was 11.88％.Through the Clarke error grid analysis,there were 98.24 ％ points located in region A and region B,only 20 paired(1.76％) glucose located in region D.Hypoglycemia was defined as glucose concentration ＜ 2.6 mmol/L,while hyperglycemia was defined as glucose concentration ＞ 7.0 mmol/L.A high/low blood glucose detected by peripheral blood glucose monitoring is a high/low blood glucose event,and a high/low blood glucose detected by GRT in a continuous period is a high/low blood glucose event.Twelve cases of hypoglycemia,26 episodes of hypoglycemia,29 cases of hyperglycemia,and 151 episodes of hyperglycemia were detected by using fast blood glucose meter.Twenty-six cases of hypoglycemia,88 episodes of hypoglycemia,38 cases of hyperglycemia,and 229 episodes of hyperglycemia were detected by using GRT.Sixty-two episodes of hypoglycemia were not detected by the fast blood glucose meter,with 14 episodes lasting longer than 30 min,4longer than 60 min,and 5 longer than 90 min.There were 78 hyperglycemic episodes that were not detected by the fast blood glucose meter,with 44 episodes lasting longer than 30 min,15 longer than 60 min,and 70 longer than 90 min.There were significant differences in the testing of hypoglycemia and pathoglycemia(x2 =7.00,18.60;all P ＜ 0.05),but,there was no significant difference in the testing of hyperglycemia between the 2 kinds of detection(x2 =2.26,P ＞0.05).GRT was acceptable to parents,medical staffs and children as only 3 infants bled when the continuous glucose sensor was imbedded,but there was no progressive increase in blood loss.There was no redness,edema,infections,or effusions at the insertion sites.Conclusions The use of GRT continuous monitoring system in high-risk infants of hypoglycemia was feasible.Compared with the conventional intermittent peripheral blood glucose monitoring,more abnormal blood glucose events and their duration could be detected.
Résumé
Objective To study the accuracy of real-time continuous monitoring system (RT-CGMS) at different stages and its association with glucose excursion. Methods Totally 33 patients with type 1 diabetes or type 2diabetes were under surveillance of RT-CGMS for 5 d. Capillary glucose values were measured 7 times daily.Correlation coefficient, error grid analysis (EGA), and Bland-Altman analysis methods were used to assess the correlation, accuracy and agreement of RT-CGMS at different stages and in general level; The mean amplitude of glucose excursion (MAGE) and the frequency of glucose excursion ( FGE ) were also calculated. Results ( 1 ) The correlation coefficient of RT-CGMS with capillary glucose values at fasting, postprandial stages, and in general level were 0.94,0.92, and 0.93 respectively( P＜0.01 ). (2) EGA showed that 98.82%, 98.39%, and 98.64% of the results fell in the A and B zones and 1. 18%, 1.61%, and 1.36% fell in the D zone respectively at fasting,postprandial stages, and in general level. There is no result fell in C and E zones. ( 3 ) The agreement analysis showed that RT-CGMS readings were in close agreement with capillary glucose values at fasting, postprandial periods, and in general level. (4)The MAGE at fasting, postprandial periods, and in general level were (3.57±2.66), (4.07±3.09), and (4. 02 ±3.04) mmol/L (P＞0. 05), (0±0. 5), (3± 1), and( 1 ±3) d for FGE (P＜0. 01 ).Conclusion RT-CGMS at fasting stage has higher accuracy than postprandial stage and general level, FGE at fasting stage is higher than postprandial stage and general level.
