Applicability of hemodialysis clearance parameter for vancomycin therapeutic drug monitoring during continuous hemodiafiltration in an infant.

Cases requiring vancomycin administration planning in infants undergoing continuous hemodiafiltration (CHDF) are extremely rare. Here, we report a single case in which vancomycin therapeutic drug monitoring and administration planning were implemented for an infant requiring CHDF. The patient was diagnosed with wound infection after gastrostomy and enterotomy surgery and received vancomycin treatment for infection with methicillin-resistant Staphylococcus epidermidis. The vancomycin trough serum concentration was successfully controlled within the acceptable range. Additionally, we discuss the potential usefulness of applying the CHDF clearance parameter for the fine management of vancomycin serum concentration in a pediatric patient undergoing CHDF.
