A unique case report of a high-pressure paint injection injury of the hand with associated carbapenemase resistant Pseudomonas aeruginosa infection

Abstract High pressure injection injuries to the hand should not be taken lightly as urgent surgical debridement is required to ensure favorable outcomes. Empiric antibiotic administration is recommended; however, few studies focus on the secondary infection risk associated with these high pressure injection injuries. We present a rare case of a patient presenting with carbapenem resistant Pseudomonas aeruginosa following a high pressure paint gun injury of the thumb. Urgent surgical debridement with administration of broad-spectrum antibiotic coverage for both gram-negative and gram-positive bacteria is recommended. The injection of foreign materials can cause extensive tissue damage and immunosuppression facilitating growth of opportunistic bacteria that are often rare in healthy adults. We advocate for obtaining cultures at initial debridement to optimize treatment in these unique and rare injection injuries. Concerns should be raised as carbapenem resistant bacteria become more prevalent in the community.
