What is the primary effect of alkali exposure on body tissues?

The primary effect of alkali exposure on body tissues is liquefactive necrosis. When alkalis come into contact with tissues, they can cause significant damage through their strong basic nature. This results in the breakdown of proteins and lipids, leading to the transformation of tissue into a viscous, liquid mass. In contrast to acids, which typically result in coagulation necrosis, alkalis facilitate the process of liquefaction, effectively dissolving the tissue.

This process often occurs in various contexts, such as chemical burns or injuries related to industrial accidents. Liquefactive necrosis is particularly seen in the case of severe burns from alkaline substances. The presence of moisture and the rapid breakdown of cellular structures are hallmark characteristics of this type of necrosis, which can lead to severe complications and prolonged healing times. Understanding this process is crucial for recognizing the severity of alkali injuries and formulating appropriate treatment strategies.
