Sodium hydroxide is also known as caustic soda and potassium hydroxide is also known as caustic soda. From their nicknames, we can clearly conclude that they are both strongly alkaline substances with strong alkalinity and corrosion. Our skin is easy to cause burns when we accidentally contact them. Burn is a very serious injury, especially due to the development of modern industry, the application of alkali has been popularized. Alkali burn is a common burn in clinic.

氢氧化钠和氢氧化钾的烧伤属于碱烧伤，其原理是因为碱对组织的吸水作用，使局部细胞发生脱水现象，碱离子与组织蛋白形成碱变性蛋白复合物，且此复合物可溶性较强，能使碱离子进一步穿透深部组织，如果我们不当，还会继续造成深部组织的伤害，使创面加深。

Sodium hydroxide and potassium hydroxide burns are alkali burns. The principle is that the water absorption of alkali on the tissue causes dehydration of local cells. Alkali ions and tissue proteins form an alkali denatured protein complex, which is highly soluble and can further penetrate the alkali ions into the deep tissue. If we do not treat it properly, it will continue to cause damage to the deep tissue, Deepen the wound.

氢氧化钠和氢氧化钾烧伤引发的症状为：创面呈黏滑或肥皂样变化，痂皮较软，有进行性加深的趋势，深度常在深Ⅱ度以上，疼痛剧烈、创面感染易并发创面脓毒症。

The symptoms caused by sodium hydroxide and potassium hydroxide burns are: the wound surface is sticky or soapy, the scab is soft, with a trend of progressive deepening, the depth is often more than deep II degree, severe pain, wound infection and wound sepsis.

当我不小心发生碱接触时要积极自救，使用大量的清水对伤口进行清洗30分钟以上，注意水的流量要足够大，一方面可以保证不会有残留物，另一方面也可减轻烧伤的痛感。也可使用一些醋酸或果酸溶液清洗。

When I accidentally come into contact with alkali, I should actively save myself. I should use a large amount of water to clean the wound for more than 30 minutes. Note that the flow of water should be large enough to ensure that there will be no residue on the one hand and reduce the pain of burns on the other hand. It can also be cleaned with some acetic acid or fruit acid solution.

发生烧伤后进行积极自救，如情况非常严重则要马上就医。因为烧伤时的初期自救对后续的影响很大，这关系到伤口是否会感染扩大。所以从事与氢氧化钠和氢氧化钾这种强碱性物质相关的工作，一定要懂得自救的处理方法。

Carry out active self rescue after burns. If the situation is very serious, seek medical treatment immediately. Because the initial self rescue during burn has a great impact on the follow-up treatment, which is related to whether the wound infection will expand. Therefore, if you are engaged in work related to strong alkaline substances such as sodium hydroxide and potassium hydroxide, you must understand the treatment method of self rescue.
