The first step after a hand burn is to stay away from the heat source, and then take appropriate treatment measures depending on the severity. This includes general treatment, medication, and symptomatic support. 1. First degree burns: If the epidermis is not broken, no blisters, only redness, swelling, pain, for the first degree burns. The burn can be rinsed repeatedly with running cold water until the pain is relieved, and then pain medication (e.g., acetaminophen) can be used to relieve the pain. 2. Second-degree burns: If there are large and small blisters, the pain is intense, for the second-degree burns. It needs to be sterilized after applying cold compresses and topical anti-infective medications (e.g., erythromycin ointment, mupirocin ointment, etc.). 3. Third-degree and above burns: If the muscle tissue under the skin is seriously damaged, it is third-degree and above burns. Immediate establishment of intravenous access, monitoring of blood pressure, respiration and other signs, rehydration therapy (e.g., balanced salt solution) and anti-infective therapy (e.g., tetanus antitoxin) are required. It is recommended to seek timely medical treatment after hand burns, and standardize treatment and medication under the guidance of a professional doctor to avoid delays.
