British scientists have invented a new "magic ointment" that illuminates when a skin infection is detected, alerting the doctor to treat it in time.
Researchers at the University of Bath in the United Kingdom said that when the ointment detects pathogenic bacteria in the wound, it triggers the nanocapsules in the ointment, which mimics the function of the skin cells and ruptures only in the presence of toxic bacteria. Does not respond to harmless bacteria that normally exist on the surface of healthy skin. When the nanocapsules rupture, they release a stain that is only visible under ultraviolet light, so that the medical staff can easily find out if the patient is likely to develop toxic shock syndrome.
Toxic shock syndrome is a rare bacterial infection that is usually harmless to the skin, but it can invade the body's blood and release toxins. These toxins can cause sudden high fever and a sharp drop in blood pressure, which can lead to dizziness and coma. They can also cause vomiting and diarrhea. In addition, these toxins can damage human tissues, including skin and organs, and disrupt many important organ functions.
About 5,000 or so children worldwide suffer from mild burns each year, and hot drinks burns are the main cause of these burns. Toxic shock syndrome is often fatal for children with burns because it can suddenly break out and a small burn can turn into a potentially fatal injury within hours.
Currently, the method of detecting bacterial infections takes 24 to 48 hours to obtain accurate results, during which time the patient is likely to die due to rapid spread of infection.
The new "magic ointment" gives doctors a quick and effective diagnostic method, and it does not interfere with the normal healing of burned skin. Researchers have experimented with some skin samples, and the method is expected to undergo human clinical trials in the next four years.
Participants in the project, a pediatric anesthesiologist at a hospital in the United Kingdom, said: "This new type of plaster means that we can detect early signs of toxic shock syndrome so that we can diagnose and treat children as soon as possible. May save thousands of children's lives."
