Efficacy of mummy on healing of pressure ulcers: A randomized controlled clinical trial on hospitalized patients in intensive care unit

Background: Mummy is a mineral substance which according to Persian medicine texts, may be useful in treatment of chronic ulcers. Objective: The present study was performed with the aim of determining the effect of mummy on healing of pressure in male patients who had been hospitalized due to cerebrospinal injury in the Intensive Care Unit. Methods: This randomized, placebo-controlled clinical trial was performed on 75 patients who had pressure ulcer at Shahid Bahonar Hospital in Kerman, Iran, from September 2016 to March 2017. The control group received normal saline and routine wound dressing, while the intervention group received mummy water solution 20% in addition to normal saline and routine wound dressing on a daily basis. Data was recorded based on the PUSH method. In both groups, ulcers were evaluated on days 0, 7, 14, 21 and 28 for the variables of ulcer surface area, the amount of exudate and type of tissue. Data analysis was done through SPSS 21 and using t-test, Repeated Measure Analysis, Cox Regression and Chi-square. Results: Both groups showed reduction in the average ulcer surface area (3.26 to 0.53 in the intervention group and 5.1 to 3.46 in the control group), the average exudate amount (1.26 to 0.26 in the intervention group and 1.83 to 1.06 in the control group) and the average tissue score (1.36 to 0.23 in the intervention group and 2.13 to 1.26 in the control group). Over the entire study period, the intervention group showed more acceptable signs of healing compared to the control group (p<0.05). Conclusion: The healing process was more prominent in the intervention group than the control group. Clinical trial registration: The trial was registered at the Iranian Registry of Clinical Trials with registered NO. (IRCT2014042917494N1) (29/04/2014). Funding: No financial support for the research.
