When exposed to the high-concentration Hydrofluoric acid(HF), the regional skin reveals some degree of surface damage, and intense pain that is easily perceived. When contacting low-concentr ation HF, such obvious pain may not happen quickly, but delayed skin injuries and pain become inevitable. Among all chemicals resulting in chemical burns, HF has now become the most common substance to cause chemical injuries in some regions of China.

Critical measures to treat Hydrofluoric acid(HF) burns include blocking progressive injury resulting from ?uoride ions. To date, wate rirrigation and calcium gluconate gel have been recommended as the mainstay of HF burns treatment, which could be bene?cial for the patients with minor HF burns. Based on the fact that distal limbs become the most common body parts of HF injuries, some methods, i.e., arterial or intravenous infusion of calcium gluconate, have been developed. Arterial infusion of can directly transport calcium ions to the burn regions, and then combine with ?uoride ions.

Hydrofluoric acid burns, the absorption of toxins is a protracted process, it is difficult to estimate the specific absorption, there is a  larger difference in clinical detoxification, and have uncertain efficacy. We have analyzed the hydrogen hydrofluoric acid burn patients, in order to investigate after hydrofluoric acid burn calculation and control methods aid in calcium dose and speed.
