What should also be used when using PMMA beads?

• A. Sterile saline flush
• B. No drainage management
• C. A drain
• D. Antibiotic irrigation

Answer: (C)

When antibiotic-loaded PMMA beads are used, they create a pocket or dead space in the wound that can fill with fluid. A drain provides a path for that fluid to exit, which helps prevent hematoma or seroma formation, reduces the risk of ongoing infection, and supports more reliable healing around the beads. The beads deliver high local antibiotic concentrations, so adding a drain addresses the fluid management aspect rather than irritation from irrigation or excessive irrigation itself. Sterile saline flush can be part of wound care for cleansing, but it does not replace the need for drainage when beads are present. Without drainage, fluid can accumulate and potentially harbor bacteria or impede healing. Antibiotic irrigation isn’t required with beads and can disrupt local concentrations or the healing environment.
