BACKGROUND: Reduction of sacrococcygeal pressure is the most direct and effective method to prevent the early sacrococcygeal pressure injury. Currently, there are a variety of materials in the market, but there is still insufficient evidence for the correct selection of pressure-relieving mattress in clinical practice. OBJECTIVE: To measure the sacrococcygeal pressure value, sacrococcygeal skin temperature value and observe the change of skin color of healthy people lying supine on three kinds of mattresses at different periods, in order to explore a medical mattress with better decompression effect. METHODS: Totally 33 healthy subjects were selected from First Affiliated Hospital of Guangzhou University of Chinese Medicine aged 18 to 35 years old, body mass index of 18.5-23.9 kg/m². At 1, 2, and 3 days of the experiment, subjects were recumbent in latex mattresses, static pressure ulcers prevention mattresses, and ordinary mattress. At set time points (0, 0.5, 1.0, 1.5, 2.0 hours), the sacral pressure value, the tail in the cauda equina compression of color, and skin temperature were detected. RESULTS AND CONCLUSION: (1) After 0.5-2 hours of test, the sacrotail pressure of latex mattress group was lower than that of static pressure ulcers prevention mattresses group and ordinary mattress group (P < 0.05). (2) There was no significant difference in the temperature values of the compression parts of the three mattress groups during 0-0.5 hours (P=0.587). During 0.5-2.0 hours of the test, the temperature of pressure position in latex mattress group was lower than that in static pressure ulcers prevention mattresses group and ordinary mattress group (P < 0.05). (3) During 0.5-1.5 hours of the test, the color of the sacrococcygeal compression parts of the subjects in the three mattress groups did not change. During the experiment of 1.5-2.0 hours, the color of the sacrococcygeal compression site of the subjects in the latex mattress group did not change, while that of the static pressure ulcers prevention mattresses group altered in one case, and that of the ordinary mattress group altered in two cases. (4) The results showed that, compared with the other two mattresses, the latex mattress can effectively reduce the sacrococcygeal pressure, and has good heat dissipation and air permeability, and plays an effective role in preventing the early pressure injury.

BACKGROUND: Soft silicone silver ion dressing, a kind of high molecular weight organic compound prepared with Safetac technology, has the characteristics of anti-infection, good permeability and good air permeability. It can provide a good moist environment for wound healing. OBJECTIVE: To evaluate the effectiveness of soft silicone silver ion dressings in repairing deep II degree and milder bum wounds. METHODS: A computer-based retrieval of CNKI, VIP, WanFang, CBM, PubMed, Embase and Web of Science databases was performed. The randomized controlled trials conceming soft silicone silver ion dressing for repairing deep II degree and milder bum wounds were selected. The treatment group was treated with a single soft silicone silver ion dressing, or a soft silicone silver ion dressing combined with conventional treatment, or combined with other treatments. The control group was treated with conventional treatment, or other treatments, or placebo. After screening, data extraction and quality evaluation, meta-analysis was performed using Review Manager 5.3 software. RESULTS AND CONCLUSION: (1) Eleven articles were included, involving 784 patients, 381 patients in the treatment group and 403 patients in the control group. (2) The results of meta-analysis showed that the bum wound healing rate in the treatment group was higher than that in the control group [OR=11.56, 95%Cl (9.60, 13.53), P < 0.000 01; OR=13.29, 95%Cl (7.54, 19.04), P < 0.000 01; OR=4.10, 95%Cl (2.28, 5.93), P < 0.000 1; OR=1.17, 95%Cl (0.42, 1.93), P=0.002] at 7, 14 and 21 days, and the last measurement. The healing time of bum wounds in the treatment group was shorter than that in the control group [OR=-2.81, 95%Cl (一3.49, -2.12), P < 0.000 01]. The degree of pain in bum wounds in the treatment group was lower than that in the control group [OR=0.38, 95%Cl (-0.53,一0.24), P < 0.000 01]. There was no significant difference in the positive rate of bacterial culture on wound surface [OR=1.16, 95%Cl (0.47, 2.85), P=0.74], bum wound infection [OR=1.44, 95%Cl (0.47, 4.41), P=0.52], dressing frequency [OR=-8.04, 95%Cl (-18.82, 2.74), P=0.14], wound treatment cost [OR=-98.26, 95%Cl (-272.91, 76.40), P=0.27] and adverse reaction [OR=0.61, 95%Cl (0.31, 1.20), P=0.15] between treatment and control groups. (3) These results show that the application of soft silicone silver ion dressing on deep II degree and milder bum wounds can improve wound healing rate, shorten wound healing time and alleviate pain.
