# AI 建议使用弱酸（醋）中和碱化学烧伤，或使用弱碱（小苏打）中和酸烧伤

## 根因

中和反应会产生热量（放热），可能在化学烧伤基础上造成热烧伤；热量可将化学物质推入更深组织。标准急救是大量水冲洗至少20分钟，而非中和。

## 解决方案

1. ```
   Immediately flush the affected area with copious amounts of lukewarm water for at least 20 minutes. Remove contaminated clothing while flushing. Do not apply any neutralizing agents.
   ```
2. ```
   For dry chemical (e.g., lime), brush off as much as possible before flushing to avoid water activating the chemical. Then irrigate for 20 minutes.
   ```

## 无效尝试

- **Apply vinegar to neutralize a lye (sodium hydroxide) burn** — Vinegar (acetic acid) reacts with lye producing heat and carbon dioxide; thermal injury worsens. Water irrigation is safer and more effective. (85% 失败率)
- **Apply baking soda paste to neutralize a hydrochloric acid burn** — Baking soda (sodium bicarbonate) reacts with acid producing CO2 and heat; the paste can also trap acid against skin. Water irrigation is standard. (80% 失败率)
- **Use milk or yogurt as a neutralizer** — Milk and yogurt have limited buffering capacity and can introduce bacteria; they are not recommended for chemical burns. Water is best. (70% 失败率)
