Improving the Use of Antibiotic Beads in the Operating Room

Antibiotic beads have been used to treat bone and soft tissue infections for the last 30 years. Antibiotics are mixed into a cement mixture and formed by hand into round balls called beads. The beads are placed inside a wound and changed every two weeks.

In this report, surgeons from the University of Illinois develop a better way to form and mold antiobiotic beads. They were able to make smaller, more uniform (size and shape) beads.

The authors describe the step-by-step process and method used to make smooth, round antibiotic beads. They used a four-millimeter cake decorator's mold to form the beads. The beads were placed in silicone trays, which were easier to remove from compared with plastic bead-making trays.

There are many advantages to this method of bead making. The smoother, more uniform size and shape of beads resulted in fewer problems with the wound. Operating room staff were exposed to fewer toxic fumes because the process was much faster than rolling them by hand.

Smaller beads made it possible to fill the wound area more completely and more evenly. Patients did not report any pain from sharp or irregular edges of the beads. Combining the antibiotics as needed in the operating room is a big advantage for the patient.

The technique described in this article simplifies and improves the production of antibiotic beads. Improved local antibiotic delivery and less discomfort to patients make this process noteworthy.
