Vancomycin extravasation outcomes

"Given the increased prevalence of meticillin-resistant Staphylococcus aureus, which has prompted clinicians to gradually increase vancomycin dosage, clinicians should be aware of the high risk of skin toxicity in cases of vancomycin high-dose extravasation" Zenati et al (2021).

Vancomycin extravasation outcomes

Abstract:

Vancomycin is a tricyclic glycopeptide antibiotic produced from Streptococcus orientalis. There is much variation in the literature with regard to the recommended dose, dilution rate and type of infusion. Given the vesicant properties of vancomycin at supratherapeutic doses (>10mg/ml), tissue damage including blistering and necrosis have been reported. We report a rare case of bilateral cutaneous necrosis induced by accidental extravasation of vancomycin when being intravenously administered. The skin surrounding the injection site was marked by the appearance of subcutaneous calcifications. The development of iatrogenic skin calcinosis has not yet been described for the extravasation of vancomycin. The mechanism underlying the calcinosis observed in our case remains unclear, but we hypothesised a form of localised calciphylaxis induced by a local triggering factor. The ulcers progressed to re-epithelialisation following necrosis debridement and local conservative treatments. Given the increased prevalence of meticillin-resistant Staphylococcus aureus, which has prompted clinicians to gradually increase vancomycin dosage, clinicians should be aware of the high risk of skin toxicity in cases of vancomycin high-dose extravasation.
