Which type of embalming fluid generally has a higher index than arterial fluids?

Cavity fluids are specifically designed to be used in the body cavities during embalming, primarily to ensure thorough preservation and disinfection of the viscera. These fluids tend to have a higher index compared to arterial fluids because they contain a greater concentration of formaldehyde and other preservatives. This higher index is necessary to effectively preserve the organs and tissues that are often in a more fragile state, having been exposed to decomposition.

The formulation of cavity fluids is tailored to address the challenges presented by the internal environment of the body cavities, where decomposition can occur rapidly if not properly treated. As a result, the higher concentration of embalming agents in cavity fluids enhances their efficacy in preserving and disinfecting these areas.

Other types of fluids, such as surface disinfectants, preservative gels, and hydrating agents, serve different purposes in the embalming process and generally contain lower concentrations of preservatives, which is not suitable for the demands of internal preservation that cavity fluids are created to meet.
