Severe bleeding after trauma frequently results in poor outcomes in children. Prehospital fluid replacement therapy is regarded as an important primary treatment option. Our study aimed, through a retrospective analysis of matched pairs, to assess the influence of prehospital fluid replacement therapy on the post-traumatic course of severely injured children. ⋯ For the first time, a tendency was shown that excessive prehospital fluid replacement in children leads to a worse clinical course with higher mortality and that excessive fluid replacement has a negative influence on the ability to coagulate.

The correction of hypovolemia with acellular fluids results in acute normovolemic anemia. Whether the choice of the infusion fluid has an impact on the maintenance of oxygen (O₂) supply during acute normovolemic anemia has not been investigated so far. ⋯ The choice of the intravenous fluid has an impact on the tolerance of acute normovolemic anemia induced by acellular volume replacement. Third-generation tetrastarch preparations (e.g., HES 130/0.4) appear most advantageous regarding maintenance of tissue oxygenation during progressive anemia. The underlying mechanism includes a lower degree of extravasation and favourable effects on microcirculatory function.

The C-MAC video laryngoscope substantially reduced poor glottic views and increased intubation success in ICU patients with at least one predictor for difficult intubation. However, all video-assisted and optical intubation devices have different view angles, thus producing different images with particular distortion, and even experts in 'old-fashioned' airway management need a substantial level of training with a certain device before using it safely and successfully in critical situations and patients. Video laryngoscopes, regardless of a particular brand or device, cannot be used intuitively - they require expert skills and routines to be turned into a life-saving airway management tool.
