Sublingual Microcirculation in Children with Compensated T1D Using the SDF Method

After recording the basic anthropometric parameters, pressure and pulse, each child who meets the inclusion criteria will have their microcirculation measured using a Sidestream Dark-Field (SDF) probe placed sublingually by one examiner using the SDF method. The measurement will be performed in supine position in a disease-free period, with normal diets, at least 2 hours after the last meal, for girls outside the menses period. Premedication or analgesia will not be used. A total of 3 video clips will be recorded from different parts of the sublingual area with a minimum length of 20 seconds in a row, unless the child needs a short break between measurements. The recorded videos will then be processed offline by one evaluator who is trained and experienced in microcirculation evaluation, three best and most stable parts of each video clip will be analysed.
