My name is Sybille Kozek, and I'm an anesthetist from Vienna, Austria. One of my main areas of interest is the potential side effects of colloids and crystalloids, particularly in relation to dilutional coagulopathy and their impact on clinical outcomes such as blood loss and transfusion requirements. In my lecture, I focused on why fluid choice truly matters—not just in terms of the type of colloid, but also the timing and dosing of its administration. I presented evidence highlighting the clear clinical advantages of using 6% iso-oncotic tetrastarch compared to gelatin, emphasizing its superiority based on the data currently available.
