A 35-year-old female was admitted for fever with swelling and pain at the site of the peripherally inserted central catheter (PICC) in her left arm. She had a PMH of gastroparesis with multiple abdominal surgeries and was reliant on total parenteral nutrition. Blood cultures revealed MSSA, and her PICC was removed for 48 h before a new one was placed. She received ceftriaxone 1 g every 24 h on days 1–3. Ceftriaxone was switched to oxacillin 2 g every 6 h on day 4. She was changed back to ceftriaxone 2 g every 24 h on day 12, then discharged to a long-term acute care (LTAC) facility on day 23. She continued ceftriaxone at LTAC for 8 additional days.
A 47-year-old male admitted for MSSA septicemia secondary to a laceration repair on the back of the head 9 days prior had positive surgical site and blood cultures with MSSA. Oxacillin 2 g every 4 h was initiated on day 4. Echocardiogram was negative for vegetations, and on day 11, antimicrobial therapy was switched to ceftriaxone 2 g every 24 h for 6 weeks of therapy.
