ObjectiveTo evaluate the effects of two different autolytic debridment on subcutaneous wounds. MethodsThirty-eight patients with subcutaneous wounds treated from January to December 2015 were numbered according to the sequence of admission, and were randomly divided into trial group and control group, with 19 patients in each group. All the patients had yellow surface. Patients in the control group were treated with amorphous hydrogel, while those in the trial group were treated with both amorphous hydrogel and alginate dressing. Then, we compared the two groups in terms of the debridement time, frequency of changing dressing, granulation growth, wound contraction rate at the end of debridement period, and leakage rate. ResultsThe debridement time in the trial group was (21.11±5.86) days, and it was significantly shorter than that in the control group[(26.69±9.68) days] (P<0.05); the frequency of changing dressing was (7.21±2.12) times, which was less than that in the control group[(9.37±3.32) times] (P<0.05); and granulation growth was better than that in the control group (2.58±0.61 vs. 1.95±0.71, P<0.05). The wound contraction rate at the end of debridement period in the trial group was (47.00±26.24)%, which was higher than that in the control group[(29.03±22.62)%] (P<0.05); and the leakage rate (0.0%) was lower than the control group (3.3%) (P<0.05). ConclusionUsing amorphous hydrogel and alginate dressing for subcutaneous wounds is better than amorphous hydrogel alone for autolytic debridement, and can lower the leakage rate.
