Which antiseptic is recommended for cleaning the site during patient preparation?

Chlorhexidine is recommended for cleaning the site during patient preparation because it effectively reduces the number of viable pathogens on the skin before invasive procedures. Its broad-spectrum antimicrobial activity is effective against both gram-positive and gram-negative bacteria, as well as certain viruses and fungi. Importantly, chlorhexidine has a residual effect, meaning it continues to provide antimicrobial protection even after the initial application, which is crucial in preventing postoperative infections.

In clinical settings, especially for procedures involving incisions or insertion of catheters, maintaining a sterile field is paramount. The use of chlorhexidine aligns with current guidelines from organizations such as the Centers for Disease Control and Prevention (CDC) and surgical societies, which emphasize its superior efficacy compared to other antiseptics. By utilizing chlorhexidine, clinicians aim to minimize the risk of surgical site infections, which can significantly impact patient outcomes and healthcare costs.
