Bleeding from trauma usually requires debridement, regardless of the depth of the wound. Cleansing refers to the removal of inactivated tissues, blood clots, foreign bodies, etc., thorough disinfection, or suturing and drainage of wounds or traumas, and other therapeutic measures. The main purpose is to prevent infection, improve local blood circulation, and promote the repair and healing of damaged tissues. Local bleeding caused by trauma generally requires timely debridement, regardless of the depth of the wound. Cleansing generally should not be later than 6 to 8 hours after the injury, such as the early use of antibiotics, the wound is not heavily contaminated, or the temperature is low, can be slightly prolonged, the longest not more than 24 hours. Slight skin abrasion wounds can be rinsed out and only wiped with iodophor or other skin disinfectant and dried; deep wounds need to be debrided by enlarging the wound or incising the fascia, removing inactivated tissues, blood clots, and foreign bodies, etc., rinsing and disinfecting the wound, and placing sutures if they can be closed, or placing drainage if they need to be drained. If trauma requires debridement, it should be carried out by a professional physician in a timely manner, and should not be handled on its own in order to minimize the chance of infection. After the operation, it is necessary to pay attention to the prevention and treatment of tetanus to prevent infection.
