During subcutaneous injections, what is a vital precaution to avoid complications?

When administering subcutaneous injections, one of the key precautions is to avoid puncturing through the skin. This is crucial because the subcutaneous tissue lies immediately beneath the skin, and the goal of the injection is to deliver medication into this layer without penetrating too deeply. If the needle punctures through the skin, it may lead to injecting into deeper tissues, which can result in complications such as improper drug absorption, damage to blood vessels or nerves, and increased risk of infection.

Moreover, proper technique in maintaining the right angle and depth of the needle insertion helps ensure that the medication is effectively delivered into the subcutaneous space. This approach not only enhances the efficacy of the treatment but also minimizes discomfort for the animal and reduces the potential for complications related to the injection. Thus, avoiding puncture through the skin directly contributes to the overall safety and effectiveness of the subcutaneous injection process.
