When you come into contact with unknown liquid, don't be careless for fear of amputation! A man engaged in resource recycling felt a sharp pain in his spine when his fingers were splashed by unknown liquid while turning over plastic garbage. After diagnosis, it was found that he was burned by hydrofluoric acid liquid. Cai Bingheng, a plastic surgeon of Attending Surgeon, said that hydrofluoric acid is very corrosive, just like "bone-melting water" in martial arts novels. If the doctor delays, the patient may have to amputate. If people come into contact with unknown liquid, it is recommended to wipe the residual liquid on the skin first, then rinse it immediately and seek medical treatment. When the 42-year-old patient arrived at the hospital, his left index finger, middle finger and ring finger were pale. Cai Bingheng pointed out that it was not caused by ordinary acid-base solution, but the empirical blood was found to be a chemical liquid, which was highly suspected to be hydrofluoric acid burn. So I urgently consulted plastic surgery and performed a finger rescue operation. After the patient passed the antidote, the pain immediately improved, and the patient's fingers were saved through debridement and skin transplantation in the operating room. Cai Bingheng said that hydrofluoric acid is usually used to remove rust or wash air conditioners. If you are burned by hydrofluoric acid, you can't treat it as an ordinary burn. The key is to inhibit the destruction of fluoride ions in hydrofluoric acid. You should inject calcium gluconate into the artery. Only after fluoride ions combine with calcium ions can you stop the corrosion on the skin. It is worth noting that hydrofluoric acid is not only harmful to the skin, but also very easy to penetrate tissues and even erode bones and muscles, causing irreparable damage. Its chemical components will enter the human body with blood and affect the heart function, causing arrhythmia and endangering life. Some patients had to have their limbs amputated because they missed the opportunity of treatment. If you accidentally come into contact with unknown liquid in your life, Cai Bingheng suggested that it is best to wipe off the liquid left on your skin at the first time and rinse it a lot. The rinsing time can be longer. Then go to the hospital for medical treatment, and the doctor will judge what kind of liquid is scalded and do the most appropriate treatment.
