Description

technical field [0001] The invention belongs to the field of medical dressings, and relates to a composition containing icodextrin for promoting wound healing and preventing scars, in particular to a formula containing the composition and an application method. [0002] technical background [0003] Wounds can be defined as skin defects caused by mechanical, electrical, thermal, chemical and other factors or due to physiological abnormalities. Wound healing is the physiological response of body tissues to injury stimuli, and is generally divided into four stages: coagulation, inflammation, proliferation, and remodeling. heal. In a paper published by Winter R in 2003, it was found that through the study of pig body tissue, the wound healed faster in a closed moist environment than in a dry state, and proposed a theory of moist healing. Afterwards, many scientists repeated the research results of Winter R on the human body, and verified that moisturizing wounds heal faster, l...
