Vancomycin flushing syndrome in orthopaedic practice: A case report.

Background: Vancomycin flushing syndrome (VFS), also known as red man syndrome, is an allergic reaction to vancomycin. It typically presents as a rash on the face, neck, and upper torso after intravenous administration of vancomycin. VFS is blamed on rapid intravenous infusion of vancomycin during management and rarely happens after local use. A review of the literature showed that in the last 23 years, 4 such cases have been reported. Here, we add another case of VFS developed after slow local absorption of vancomycin in cement beads.

Case summary: A 44-year-old male with a known case of hypertension, no history of allergies to medications, and a history of chronic osteomyelitis of the right tibia with discharging sinus over the anterolateral aspect of the leg. The pus culture grew Staphylococcus aureus, which was sensitive to clindamycin and vancomycin. The patient underwent irrigation and debridement with the placement of vancomycin cement beads made from 4 g of vancomycin powder and 40 g of polymethyl methacrylate. Three hours postoperatively, the patient developed a pruritic, erythematous, macular rash predominantly on his face, neck, chest, and lower extremities and to a lesser extent his upper extremities. A diagnosis of VFS was made and was successfully treated with cetirizine (10 mg, oral) and methylprednisolone sodium succinate (125 mg, intravenous). The patient continued to have itching with a facial rash for 12 h with gradual improvement. A decision was made to not remove the beads as the patient continued to improve. Gradually, the rash disappeared after 96 h with no further sequela.

Conclusion: VFS can occur not only after rapid intravenous injection of vancomycin but also with local release, as in our case. As orthopaedic surgeons routinely use vancomycin with polymethyl methacrylate in chronic osteomyelitis and revision arthroplasty, they should be aware of such a complication occurring.
