The Flash glucose monitoring System(FGMS) is a system of measurement of the interstitial glucose levels in real time, safe, effective and doesn´t require calibration. Its low cost has allowed to be approved for all children under 18 years old by our Regional Health Service.

Objective: To assess the impact during this first year of use of FGMS in all children diagnosed with type 1 diabetes who previously used the classic method of capillary blood glucose. Everybody was trained in the use of this system.

Material and Methods: 80 children and adolescents participated in the study, assessing age, sex, age at diagnosis, duration of diabetes, insulin treatment they received, age at the onset of FGMS, pre-onset average HbA1c, HbA1c at onset and 3-6-12 months, number of blood glucose for verifying pathological values(Hypo-Hyper), registration of insulin doses and problems they could have with FGMS.

Results: 80 patients, 49%(39) males, mean age 13.55±3.16 years (5.2-19), duration of diabetes 6±3.99 years (1.4-13.9), middle ages at debut 7.5 ± 3.63 years (0.8-16), insulin treatment 70%(56) multiple doses, 16%(13) use subcutaneous catheters(Insuflon*, I-Port*), 14%(11) ISCI, age at the beginning of FGMS 12.28±3.31(3.8-18.4), mean HbA1c in the last year before to use of FGMS 7.58±0.75, HbA1c at baseline 7.66±1, HbA1c at 3 months 7.57±0.9, at 6 months 7.54±0.8, at 12 months 7.74±0.8, percentage of capillary glucose: didn`t perform any 25%(20), occasionally (1-2/14 days) 31.2%(25) and sometimes (1-2 week) 21.3%(17) and always in situations of hyper/hypo 22.5%(18), in the last group included those are receiving treatment with ISCI. They wrote down doses of insulin 42.5%(34), didn´t write anything 33.75%(27), occasionally 23.75% (19). Satisfaction state of FGMS is good 86.3%(69). They didn´t have any problems with this method of control 82.5%(66), it took off before 14 days 15%(12), allergic reaction 1.25%(1), supply failure 1.25%(1). There hasn´t been event of severe hypoglycemia

Conclusions: The FGMS is a safe, effective and well-accepted method for the diabetic patient and the family, improving the quality of life of both, however the impact on the improvement of HbA1c was only observed in the first months because they got used to the comfort of the method and forgot blood glucose control recommended in extreme situations and therefore the results weren´t as expected
