This will improve the accuracy of the doctor's medication, reduce the amount of antibiotics, and avoid bacterial resistance.
Researchers at the University of Bath said that it has been difficult for doctors to quickly diagnose a patient's wound infection. The current test method takes up to 48 hours to produce results, and the dressing to protect the wound is removed. This process is for patients. It is more painful and may leave scars.
The child's own immune system is not yet mature, and the wound is more prone to bacterial infection. Doctors often take antibiotics to prevent deterioration when burned children show signs of wound infection, but antibiotics are more likely to cause resistance.
The wound dressings released by the University of Bath were developed to solve the above problems. Toby Jenkins, an expert who led the research, said the new dressing contains many nanocapsules containing fluorescent dyes. This capsule will only rupture and release the fluorescent dye when the bacteria in the wound secrete toxins. On the surface, the entire dressing will show a fluorescent color.
With this obvious sign, the doctor can quickly determine whether the patient's wound is inflamed, how serious, and then the right medicine, not only can improve the efficacy, but also avoid excessive use of antibiotics.
According to the plan, the researchers will further test the actual effect of the new wound dressing on burn wounds.
Losing weight is a behavioral pattern aimed at reducing excess body fat and weight. Moderate weight loss reduces the risk of obesity and improves the health of patients with obesity complications.
There are two main types of commonly used drugs for the treatment of obesity: one is appetite suppressants that act on the central nervous system: these drugs are also known as anorexia drugs, which reduce serotonin and norepinephrine by affecting the activity of neurotransmitters. Reintake, thereby reducing food intake, suppressing appetite and increasing basal metabolic rate for weight loss, such as sibutamin. There is also a lipase inhibitor that acts on the periphery: by blocking the absorption of part of the fat in the diet to achieve weight loss, patients requiring drug treatment with a BMI greater than 30kg/m2 and no comorbidities, or greater than 28kg/m2 with other comorbidities .
