Objective: To compare the healing process of pressure ulcers treated with
cryopreserved human amniotic membrane allograft and routine pressure ulcer care
in our hospital.
Methods: From January 2012 to December 2013, in a prospective randomized clinical
trial (IRCT201612041335N2), 24 patients with second and third stage of pressure
ulcers were enrolled in this study. All patients needed split-thickness skin
grafts for pressure ulcer-wound coverage. Selected patients had symmetric ulcers
on both upper and lower extremities. The patients were randomly divided into two
groups: amnion and control. In the amnion group, the ulcer was covered with
cryopreserved amniotic membrane and in the control group it was treated with
local Dilantin powder application. The duration and success rate of complete
healing was compared between the two groups.
Results: The study group was composed of 24 pressure ulcers in 24 patients (19
males and 5 females) with a mean age of 44±12.70 years. The demographic
characteristics, ulcer area, and underlying diseases were similar in both groups.
The early sign of response, such as decrease in wound discharge, was detected
12-14 days after biological dressing. Complete pressure ulcer healing occurred
only in the amnion group (p< 0.001). Partial healing was significantly higher in
the amnion group (p< 0.03). Healing time in this group was faster than that the
control group (20 days versus 54 days). No major complication was recorded with
amniotic membrane dressing.
Conclusion: Cryopreserved amniotic membrane is an effective biologic dressing
that promotes re-epithelialization in pressure ulcers.
