Research Projects

Free tissue transfers are increasingly used in post-operative care, including wound reconstruction and post-cancer resection surgeries. These transfers involve transferring tissue and blood vessels under a microscope, allowing for post-traumatic amputations and transplantation surgeries. However, up to 25 surgeries may experience complications due to irreversible obstruction of blood flow. Early surgical intervention can decrease these risks and save lives. Current monitoring systems, such as manual monitoring, are labor-intensive and require expertise. In India, newer methods like laser dopplers and implantable dopplers may not be suitable for large units. A new project aims to develop a monitoring system based on changes in tissue physiologic parameters, such as color, temperature, pulse, and oxygen concentration. This system will create an early alarm-based device that can detect tissue perfusion problems, allowing for surgical exploration, obstruction removal, and successful outcomes. The device will be cost-effective for Indian hospitals and require minimal expertise. The project will involve collaboration between the International School of Bio Design at AIIMS and Hiroshima University researchers.
