What is the primary use of a splash block?

The primary use of a splash block is to provide surface anesthesia. This technique involves applying a local anesthetic agent to a specific area of the skin or mucous membranes, effectively numbing the surface without penetrating deeply into the tissues. It is particularly useful in situations where quick relief from superficial pain is needed, such as minor surgical procedures or skin lesions.

Surface anesthesia is typically employed because it allows for a rapid onset of anesthesia with minimal side effects, making it a preferred method for certain short-term applications. In this context, the splash block can be seen as an effective way to manage localized discomfort while avoiding the risks associated with deeper anesthetic techniques. This is particularly advantageous in outpatient settings where patient recovery time and comfort are important considerations.
