(b) In the study group, the degree of wound wetness on the 7th postoperative day was less than that on the 3rd postoperative day. (c) On the third day after surgery, the wound surface of the control group was oozing, accompanied by a large area of surrounding skin wet. (d) Fluid that can flow is still visible on the surface of the wound, although there is no obvious fluid in the skin surrounding the wound.
