Whether the pus in the patient’s body with pus will be absorbed by itself is objectively analyzed based on the patient’s own absorption ability, the amount of pus in the body and whether the pus causes acute infection. If the patient is old and weak, his own absorption ability is poor, and there is serious infection and large amount of pus formation in the body, the pus cannot be absorbed by itself, and the local infection will be progressively aggravated over time, and the amount of pus will gradually increase, thus causing serious infection in the patient, and even infectious shock, which is life-threatening. Second, if the patient belongs to young and strong, the body’s own repair ability is strong, the amount of pus in the body is small and does not cause acute infection, even if no active anti-infection treatment is given, a small amount of pus in the patient’s body can be absorbed by itself, thus achieving better treatment results and not causing serious complications.
