根因分析

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。

English

Neutralization reactions produce heat (exothermic) which can cause thermal burns on top of chemical burns; the heat can drive chemicals deeper into tissue. Standard first aid is copious water irrigation for at least 20 minutes, not neutralization.

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

常见但无效的做法:

  1. Apply vinegar to neutralize a lye (sodium hydroxide) burn 85% 失败

    Vinegar (acetic acid) reacts with lye producing heat and carbon dioxide; thermal injury worsens. Water irrigation is safer and more effective.

  2. Apply baking soda paste to neutralize a hydrochloric acid burn 80% 失败

    Baking soda (sodium bicarbonate) reacts with acid producing CO2 and heat; the paste can also trap acid against skin. Water irrigation is standard.

  3. Use milk or yogurt as a neutralizer 70% 失败

    Milk and yogurt have limited buffering capacity and can introduce bacteria; they are not recommended for chemical burns. Water is best.
