New gel may prevent stubborn biofilm in bedsores

This study tests whether a gel containing polyhexanide and biguanide can prevent biofilm (a tough layer of bacteria) from forming in pressure ulcers (bedsores). About 140 adults over 65 with stage II or III bedsores will receive the gel alone or with a special dressing. The goal is to see if this approach helps the wounds heal better within four weeks.
