Diagnostic and risk stratification are limited in emergencies. The measurement of microcirculation might identify patients with poor perfusion but compensated macrocirculation such as beginning shock. This proof-of-concept study examines whether sublingual prehospital sidestream dark-field microscopy is feasible.This prospective observational included receiving medical aid by an emergency ambulance who had a spontaneous circulation offered access to the mucosa. Sublingual was performed using dark field camera. Video quality evaluated image score (microcirculation score). AVA 4.3C software calculated microcirculatory parameters.Thirty (47% male) were included. average age 63 years (±20 SD), severity disease (quantified National Advisory Committee on Aeronautics) 3.4 (±0.7 SD). Macrocirculation presented within normal range. most frequent cause preventing time-critical (64%). In 17 (57%), videos could be analyzed immediately. video 2.2 ± 0.45 points ('acceptable'). There minor restrictions microcirculation. Microcirculation correlated Aeronautics, not macrocirculation. No complications occurred.The safe valid. Despite macrocirculation, impaired Aeronautics.
