Synopsis

Source of validity: Scientific
Rating (out of 5): 4

Type-A Polymers, particularly those derived from chitosan and other biopolymers, are scientifically validated for use in supporting or treating external bleeding. Numerous studies have demonstrated that these polymers can promote hemostasis by rapidly accelerating clot formation when applied to bleeding wounds. The mechanism involves the polymer’s positive charge, which attracts negatively charged red blood cells and platelets, leading to the formation of a stable clot. Products containing Type-A Polymers, such as hemostatic dressings and bandages, are widely used in emergency medicine, military settings, and surgical procedures for external hemorrhage control.

Clinical trials and in vivo studies have shown that chitosan-based and other Type-A Polymer dressings reduce time to hemostasis, decrease total blood loss, and improve survival rates in traumatic injuries compared to standard gauze. These findings have led to regulatory approvals (such as FDA clearance in the United States) and their inclusion in trauma kits worldwide. While the majority of evidence supports their use for external—not internal—bleeding, ongoing research continues to optimize formulations and delivery systems. Thus, the use of Type-A Polymers for external bleeding is strongly supported by scientific evidence and clinical practice.
