First seen Feb 06, 2026 · Last updated May 15, 2026 · Updated 15 times

Summary

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 bedridden adults over 65 with stage 2 or 3 bedsores will receive the gel alone or with a special dressing. The goal is to see if this helps the sores heal better within 4 weeks.
