A novel technology utilizing incredibly small particles offers a potential breakthrough in treating severe internal bleeding, a leading cause of preventable death. Researchers at Texas A&M University have developed injectable nanomaterials that significantly reduce blood clotting time, potentially offering a critical advantage during the “golden hour” – the first hour after a traumatic injury when rapid medical intervention is most crucial.
The innovation, inspired by ancient use of clay for wound healing, centers around nanoscale silicate particles combined with an expandable foam or fine mesh. These materials interact with body heat to create a network that stops blood flow from severed vessels and secures the particles in place, according to the research.
Currently, severe traumatic injuries pose a life-threatening risk due to rapid blood loss leading to hemorrhagic shock. Traditional methods, such as direct pressure, are often ineffective for deep internal bleeding. This new approach aims to address that critical gap in care.
Studies published in the journals Advanced Science and Advanced Functional Materials demonstrate that the new materials can reduce blood clotting time by as much as 70%, shortening the process from six to seven minutes to just one or two minutes. This accelerated clotting time could dramatically improve survival rates for patients with severe internal injuries.
“Putting these materials in first aid kits and soldiers’ packs could make a big difference,” said Akhilesh Gaharwar, professor of biomedical engineering, who led the research team. “Even saving 30 to 40% of those with severe bleeding would be a huge accomplishment.”
The technology is also designed to be safe and prevent infection, addressing another major concern in trauma care. The materials are intended for use in cases of deep internal bleeding where conventional methods are insufficient.
This development offers a promising new avenue for improving outcomes in emergency situations and underscores the potential of nanotechnology in revolutionizing medical treatments. The faster clotting times afforded by this technology could provide patients with valuable time to reach medical care and increase their chances of survival.
