Abstract: Objective To investigate the clinical effect of vacuum sealing drainage(VSD) combined with silver ion dressing to treat infectious orthopedic wounds. Methods 30 patients who met the screening criteria from October 2019 to June 2021 were selected and randomly divided into experimental group and control group,15 patients in each group.The control group was treated with conventional VSD,and the experimental group was treated with VSD combined with silver ion dressing.One week later,the bacterial clearance rate and granulation tissue coverage rate of the two groups were analyzed and compared.The wound healing time and total effective rate of the two groups were recorded and statistically analyzed. Results After one week,the bacterial clearance rate of the experimental group was (97.90±1.34)%,which was significantly higher than that of the control group(89.58±1.26)%(P<0.05).The coverage rate of granulation tissue in experimental group was (89.59±2.05)%,which was significantly higher than (76.02±1.69)% in control group(P<0.05).The wound healing time of the experimental group was (17.67±1.18)days,which was significantly shorter than that of the control group(22.33±2.09)days(P<0.05).The effective rate of the experimental group was 93.33%,higher than that of the control group(73.33%),and the difference was statistically significant(P<0.05).Conclusion For infectious orthopedic wounds,VSD combined with silver ion dressing can effectively reduce wound infection and promote wound healing.
