Abstract: Objective To compare the therapeutic effect of silver ion antibacterial dressing and povidone iodine gauze on the incision and drainage of the abscess.
Methods From March 2019 to November 2019,62 patients were included in this study,and divided randomly into the observation group and the control group with 31 cases in each group.The patients in the observation group were treated with silver ion antibacterial dressing,while the patients in the control group were treated with povidone iodine gauze.The patients in the two groups were recorded in detail.The infection control time of abscess incision was compared before treatment,the third day and the second week after the first treatment,the number of dressing changes and wound healing time of the two groups,and the clinical effect of the patients was evaluated.
Results .The time of wound control in the observation group was (13.9±1.81)d,shorter than that in the control group (23.4±2.32)d(P<0.05);the BWATBWAT(Bates-Jensen Wound  assessment tool，BWAT) score of the observation group in the second week after the first treatment was (14.98±1.51),lower than that in the control group (19.78±2.46)(P<0.05);the times of drug change and wound healing in the Observation group were significantly shorter than that in the control group(P<0.05).
Conclusion Compared with the traditional povidone iodine gauze,the silver ion antibacterial dressing can control the wound infection and improve the wound healing more quickly,and the dressing change times are less,the wound healing time is obviously shortened.
