Necrotizing fasciitis secondary to lake water inoculation with Aeromonas sobria

摘要

RATIONALE:Necrotizing fasciitis (NF) is a rapidly progressing bacterial soft tissue infection with a high mortality rate. It is characterized by significant soft tissue destruction with associated sepsis. The mainstay of treatment is coverage with appropriate broad-spectrum antibiotic therapy and emergent surgical debridement.PATIENT CONCERNS:A previously healthy 66-year-old female presented with a deep laceration to her right, posterior calf with subsequent contamination with lake water. After the wound was irrigated and closed, the patient developed NF.DIAGNOSIS:Laceration of the right lower extremity complicated by NF secondary to Aeromonas sobria.INTERVENTIONS:The patient underwent emergent surgical debridements with intravenous broad-spectrum antibiotics and negative pressure wound therapy. The lower extremity was reconstructed with split-thickness skin grafts.OUTCOMES:The patient's initial penetrating trauma was closed in the emergency room, and the patient was discharged home with antibiotics. She returned the next day with unstable vitals and was admitted to the intensive care unit. Her condition continued to deteriorate, and she underwent serial surgical debridements. Her condition improved and was discharged home after 13?days in the hospital.LESSONS LEARNED:Close monitoring for NF is important for tissue infections sustained in aquatic environments. Timely identification and surgical management of NF increases overall survival.Copyright ? 2021 the Author(s). Published by Wolters Kluwer Health, Inc.
