Tissue fluid exudate can be wiped off because tissue fluid is a normal fluid secreted by the body and is a fluid produced to protect the local wound from bacterial infection and at the same time can help repair the wound. If the exudate is more, it is recommended to go to the hospital surgery or emergency department for disposal as soon as possible, and the doctor will give regular drug changes if necessary. If the exudate is relatively small, it can be left alone at this time without much effect on the patient. Try not to expose the area to the sun during the treatment period in order to prevent pigmentation which may affect the aesthetics, and also cause the local granulation tissue to become too dry, which may also affect the healing speed. Patients should also adjust their diet, such as not drinking drinks containing alcohol, not eating too spicy food, and not eating pickled food. Fresh fruits and green vegetables can be consumed appropriately, and high quality protein foods with low fat can be consumed appropriately to promote the healing of the wound as soon as possible.
