Sclerosing edema of the palm is a localized edema of the palm tissue due to inflammation from trauma, infection, and autoimmune factors. Sclerosing edema appears in the uncinate of the palm, with flushing in the early stages and characteristic large flakes of finger peeling during the recovery period, commonly at the skin junction of the nail bed. What are the preventive methods for hard edema of the palm? 1, active treatment of various primary factors. 2, traumatic early elimination of exposed wounds and effective control of infection, if possible, if the conditions can be coupled with hyperbaric oxygen therapy will be more conducive to the absorption of edema. 3.Rational joint use of antibiotics. 4.Elevate the affected limb and maintain the local temperature to facilitate the absorption of edema fluid, blood reflux and inflammation. Rehabilitation treatment and functional training should be carried out throughout the treatment after hand trauma. After the hand is stabbed, don’t just care about the size of the wound and the amount of bleeding, what is important is to determine whether there is any broken stinger left in the wound. If there is, first try to pull it out, apply alcohol to disinfect around the wound, and try to pull out the stinger completely with forceps that have been sterilized by fire or alcohol. If the exposed part of the thorn is too short for the forceps to hold, use a sterilized needle to open the outer skin of the wound, enlarge the wound appropriately so that the thorn is exposed as much as possible, hold it and pull it out gently. After confirming that there is no thorn, gently squeeze the wound to squeeze out the blood to reduce the chance of reinfection. Finally, iodine disinfection around the wound once, alcohol 2 times, with sterile gauze bandage. You can take Synthroid to prevent inflammation if you are still unsure.
