What is the recommended disinfectant for blood culture sites in infants 2 months and older?

Chlorhexidine gluconate is the recommended disinfectant for blood culture sites in infants aged 2 months and older due to its broad-spectrum antimicrobial activity and residual effect, which helps prevent infections. It is particularly effective against both gram-positive and gram-negative bacteria and has been shown to reduce the risk of bloodstream infections when used prior to blood draws.

In the case of infants, it is crucial to use a disinfectant that minimizes the risk of skin irritation or adverse reactions, and chlorhexidine fits these criteria well. It is generally more effective than alternatives such as alcohol or iodine, especially in providing lasting antimicrobial protection.

While alcohol is effective at killing bacteria, it does not have the same residual effects and can dry out the skin, potentially leading to irritation. Iodine is an effective antiseptic but can also cause allergic reactions in some individuals, and its application may be inappropriate for certain populations. Hydrogen peroxide, although it has antiseptic properties, is not typically recommended for skin disinfection due to its potential to cause irritation and damage to the tissue.

Therefore, the choice of chlorhexidine gluconate aligns with best practices for preparing blood culture sites in infants, reflecting both effectiveness and safety in this vulnerable population.
