Deep second-degree burns ooze fluid for more than two days. After a burn, body fluids ooze out rapidly, fastest within 6 to 12 hours after the injury, lasting 24 to 36 hours, and extending to more than 48 hours in severe burns. When a deep second-degree burn occurs, the oozing period is usually already very severe and lasts more than two days. When the wound is below the papillary layer of the dermis, but some of the reticular layer remains, it is a deep second-degree burn, when sensation is dulled, the temperature is lower, and the epithelium can still regenerate. The wound usually heals on its own in 3 to 4 weeks if it is not infected. Burn exudate will make the body fluid decrease, and can cause shock in severe cases. Early burns can be rehydrated orally or intravenously, while antibiotics such as cefuroxime and tetanus antitoxin can be used to prevent infection. Exposure therapy is recommended for the management of deep second-degree burns, and bandaging may be considered when the air is cold on the day. After the occurrence of deep second-degree burns, due to poor control of infection, severe oozing, etc., it is recommended to seek timely medical treatment to avoid serious development of the disease.
