The absorption time of hemostatic gelatin sponge is not fixed, and it usually needs to be judged according to the actual situation of patients and the quality of hemostatic gelatin sponge. For patients with less bleeding at the wound site, using hemostatic gelatin sponge to stop bleeding takes a long time to absorb, and it takes 14-2 1 day to absorb. If the amount of bleeding is large, the absorption time will be shorter, about 4-5 days. In addition, the quality of hemostatic gelatin sponge will also affect the absorption time. For hemostatic gelatin sponge with good hemostatic effect and fast absorption speed, it usually takes 1-2 weeks to be completely absorbed; However, the poor quality hemostatic gelatin sponge needs more than 1 month to be completely absorbed.
