Abstract:Objective To investigate the effect of early, middle and late three stages of Chinese medicine decoction gauze sequential dressing change on wound healing after low simple anal fistula operation. Methods One hundred and eighteen patients with low simple anal fistula from January 2018 to January 2020 in Lu′an Hospital of Traditional Chinese Medicine of Anhui Province were selected by using stratified sampling method. They were divided into two groups by using random number table method, with 59 cases in each group. Control group was treated with Vaseline Oil, and study group was treated with gauze of traditional Chinese medicine decoction at early, middle and late three stages. Visual analogue scale (VAS), wound bleeding score, wound exudate score and wound area were compared between two groups before and after treatment, and the wound healing rate, wound healing time and postoperative wound related complications were counted. Results The overall analysis showed that there were significant differences in VAS, wound bleeding and exudate score between groups, time point comparison and interaction (P < 0.05). It was suggested that the postoperative wound bleeding and exudation of two groups were significantly improved, and the pain became lighter and lighter. Further pairwise comparison, intra group comparison: VAS score of the patients in two groups decreased gradually compared with that before treatment in the first week, the second week and the third week after operation (P < 0.05). Comparison between groups: VAS of study group at the first week, the second week and the third week after operation was significantly lower than that of control group (P < 0.05). Intra group comparison: at the first week, the second week and the third week after operation, the wound bleeding, exudate integral and wound area of two groups were gradually reduced compared with those before treatment (P < 0.05). Comparison between groups: the wound bleeding, exudation integral and wound area of study group at the first week, the second week and the third week after operation were lower or smaller than those of control group (P < 0.05). The wound healing rate of study group was higher than that of control group at the third week after operation, and the wound healing time was shorter than that of control group (P < 0.05). The incidence of wound related complications in study group was lower than that in control group (P < 0.05). Conclusion The sequential dressing change of traditional Chinese medicine decoction gauze in the early, middle and late three stages after the operation of low simple anal fistula can reduce the degree of pain, reduce the blood and liquid oozing from the wound, improve the wound healing effect and reduce the risk of wound related complications.
