Summary

This study tested two types of special mattresses—the Fluid Immersion Simulation (FIS) system and the Air Fluidized Bed (AFB)—to see which helps heal surgically closed pressure ulcers (bedsores) better. Eighty adults with stage III or IV bedsores were randomly assigned to one mattress after surgery. The main goal was to check wound closure after 2 weeks and compare complication rates like reopening or infection.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Fluid Immersion Simulation System (special mattress) vs. Air Fluidized Bed (special mattress)
What this could lead to: If one mattress works better, it could improve healing and reduce complications after pressure ulcer surgery.
What could go wrong: This is a small, completed trial with only 80 participants, so results may not apply to everyone. The study compares devices, not a new drug or cure.
