Abstract: To summarize the nursing experience of a patient with severe hydrofluoric acid burn. Responding to the high corrosiveness and high permeability of hydrofluoric acid,the nurses assisted the doctor to remove wound blisters as soon as possible after the exposure history was confirmed in the emergency department,and implemented calcium supplementation by two ways to prevent further damage of hydrofluoric acid. We implemented the goal-oriented fluid management in the early stage of burns to reduce the toxic effects on the heart,closely monitored the levels of free calcium and fluoride,and combined with bedside continuous renal replacement therapy to promote the excretion of fluoride from the body. At the same time,in view of the characteristics of progressive tissue necrosis of hydrofluoric acid burns,the wound debridement and repairing operation were performed as soon as possible,and the perioperative wound management was implemented. As the patient had ICU delirium,the cluster management strategy was implemented. On the 18th day of admission,the patient was in a stable condition and transferred to a general ward to continue turning frame and dressing changing treatment. On the 32th day,the wound was healed and he was discharged.
