Antifungal lock therapy with combined 70% ethanol and micafungin in a critically ill infant.

So-called lock therapy, consisting of high concentrations of antimicrobials instilled into the lumen of the catheter, has been suggested avoid central venous catheter removal during fungal infection. We report a baby who developed catheter-related candidemia. Systemic antifungal treatment did not resolve the candidemia. Lock therapy with 0.3 mL of ethanol 70% and micafungin sodium 5 mg/L was added to the therapy, and blood cultures became sterile.
