Research Summary
Objectives : to evaluate the effectiveness of silver-impregnated silicone foam gauze in wound treatment for patients with second-degree burns.
Methods : 84 patients with second degree burns were selected, divided into 2 groups: study group and control group (n=42). After the burn was cleaned, the patient in the study group was covered with silver-impregnated silicone sponge on the burn surface, while the patient in the control group was applied silver sulfadiazine cream (60g/100cm2). The two groups were examined and evaluated for their wounds weekly. The researcher takes the wound fluid to perform a bacterial culture, then quantifies and records the relevant indicators.
Result: 37 patients in the study group (88.1%) and 36 patients in the control group (85.7%) recovered almost normally, only 3 (7.1%) cases in the study group and 2 (4.8%) cases in the control group the wound did not fully recover. The healing rate in the two groups was almost the same (p>0.05), but the patients who did not recover in the group using silver silicone sponge had a faster healing rate than the control group (88%, 90% , 91% and 65%, 78%, p<0.05). In general, the healing time was much faster in the study group than in the control group (22.3±3.1 and 25.1±4.4, p<0.05). The study showed that, from day 7 to day 21, the wound in the group using silver silicone sponge gauze improved better than the group using silver sulfadiazine cream (p<0.05), however, when evaluated in On day 28, researchers found almost no difference between the two groups. The percentage of patients who were positive when carrying out a bacterial culture of wound fluid was also significantly different between the two groups at day 7, 14, and 21, with the percentage of patients being positive in the study group and the group. controls were 23.8%, 14.3%, 6.1% and 40.4%, 35.7%, and 25.6%, respectively. The skin around the wound in the study group was less damaged than the control group. The researcher observed that the percentage of patients with normal wound skin was 96.3% in the study group and 88.6% in the control group (p>0.05 except day 14). Most days during wound treatment (except for the 28th day), patients in the study group had symptoms of inflammation, pain with the rate of positive patients in the study group and control group were 23.8%, 14.3%, 6.1% and 40.4%, 35.7%, 25.6%, respectively. The skin around the wound in the study group was less damaged than the control group. The researcher observed that the percentage of patients with normal wound skin was 96.3% in the study group and 88.6% in the control group (p>0.05 except day 14). Most days during wound treatment (except for the 28th day), patients in the study group had symptoms of inflammation, pain with the rate of positive patients in the study group and control group were 23.8%, 14.3%, 6.1% and 40.4%, 35.7%, 25.6%, respectively. The skin around the wound in the study group was less damaged than the control group. The researcher observed that the percentage of patients with normal wound skin was 96.3% in the study group and 88.6% in the control group (p>0.05 except day 14). Most days during wound treatment (except for the 28th day), patients in the study group had symptoms of inflammation, painmuch lower than the control group (p<0.05). This difference was clearly shown at day 7 and day 14 (p<0.01). From day 7 to day 28, the study group felt less burning than the control group (p<0.05). Although, both groups felt anxious every time the dressing was changed (p>0.05), but the dressing change was much easier in the research group than in the control group (p<0.05).
Bottom Line: Silver-impregnated silicone foam swabs make removing bacteria faster, easier and safer. Not only that, silver-impregnated sponges also help promote healing, shorten treatment time, and patients do not experience pain each time the gauze is changed.
