“…Meanwhile, the red blood cells adhere to the chitosan threads due to the Coulomb attractive force because they have opposite charges, coating one or, at most, several layers of red blood cells on the gauze. At the same time, H+ ions are continuously released from the chitosan (associated with NH 3 molecules) into the blood, reducing the negative charges on the surrounding red blood cells (associated with COO molecules) and thus the repulsive electrical force of the double layer between the red blood cells [33]. As a result, the red blood cells in the vicinity of the gauze aggregate with each other and adhere to the layer(s) previously smeared on the gauze.…”

Wounds caused by trauma and/or surgery represent a significant challenge in contemporary medical practice, requiring innovative approaches to promote optimal healing and reduce the risk of bleeding and complications resulting from it. In this context, chitosan, a natural polysaccharide derived from chitin, represents an ideal material for the study and application of medical devices, in the form of dressings, in wound management for pre- and/or post-operative wounds due to its ability to induce hemostasis and its high biocompatibility with biological tissues. The aim of this work was to discuss the structural characteristics, properties and application of chitosan-based hemostatic dressings in hemostatic processes resulting from pre- or post-surgical approaches.
