Chlorhexidine versus povidone-iodine for central venous catheter site care in children.

The number of children receiving central venous catheters (CVCs) for the administration of medications is at an all-time high. Unfortunately, placement of these CVCs is not without risks. Infection of CVC insertion sites is one of the most common, yet often preventable, causes of nosocomial bacteremia in both children and adults worldwide. Throughout the years, multiple practice recommendations have been made regarding the proper site care of CVCs. The most popular antimicrobial solution used for site care has traditionally been povidone-iodine. Chlorhexidine gluconate solution, however, has been shown to be more effective than povidone-iodine in preventing CVC-related infections in adults. There continues to be controversy regarding the efficacy and safety of antimicrobial solutions for pediatric CVC site care. An evidence-based approach was used to determine current recommendations for CVC site care in children.
