Objective:To investigate the effect of different temperature and time treatment of Xiaoying Fang on wound healing after mixed hemorrhoid surgery.Methods:A total of 160 patients with mixed hemorrhoids who underwent surgical treatment in Fuyang Hospital of Traditional Chinese Medicine from September 2020 to October 2023 were prospectively selected as the study objects, according to the random number table method and the patients who withdrew were excluded, and 157 cases were finally enrolled, and the patients were divided into observation group 1 (39 cases), observation group 2 (40 cases), observation group 3 (38 cases) and observation group 4 (40 cases). The four groups were all treated with Xiaoying Fang hip bath after surgery. The temperature and time of hip bath in group 1 were observed at 38 - 41 ℃ for 10 min, group 2 at 38 - 41 ℃ for 15 min, group 3 at 42 - 45 ℃ for 10 min, and group 4 at 42 - 45 ℃ for 15 min. Wound pain, edema, wound granulation growth and wound healing were compared between the four groups after treatment.Results:At the 3rd and 5th day of treatment, the visual analogue scale (VAS) scores in the observation group 1 and observation group 2 were lower than those in the observation group 3 and observation group 4: (4.33 ± 1.19), (4.43 ± 1.13) scores vs. (5.15 ± 1.05), (5.40 ± 1.26) scores; (2.46 ± 1.25), (2.63 ± 0.54) scores vs. (3.61 ± 1.22), (3.85 ± 1.05) scores, there were statistical differences ( P<0.05). The wound edema scores in the observation group 2 were lower than that in the observation group 1, observation group 3 and observation group 4: (1.43 ± 0.50) scores vs. (2.21 ± 0.83), (2.05 ± 0.84), (1.98 ± 0.86) scores; (0.88 ± 0.22) scores vs. (1.38 ± 0.54), (1.00 ± 0.23), (0.93 ± 0.25) scores, there were statistical differences ( P<0.05). On the 3rd, 5th and 7th day of treatment, the wound granulation growth scores in the observation group 2 was lower than that in the observation group 1, observation group 3 and observation group 4: (0.80 ± 0.08) scores vs. (1.36 ± 0.13), (1.42 ± 0.13), (1.53 ± 0.15) scores; (0.65 ± 0.18) scores vs. (1.08 ± 0.17), (1.07 ± 0.21), (1.03 ± 0.10) scores; (0.35 ± 0.08) scores vs. (0.74 ± 0.17), (0.97 ± 0.15), (0.78 ± 0.09) scores, there were statistical differences ( P<0.05). There was significant difference in wound healing among the four groups after operation 7 d ( H = 9.84, P<0.05). The total effective rate of wound healing in the observation group 2 was the highest, which was 92.50% (37/40). Conclusions:The optimal temperature and treatment time of Xiaoying Fang hip bath are 38 - 41 ℃ and 15 min.
