Ensure that the surgical site is clean to prevent infection. If there is blood scab or secretion on the wound, it can be wiped with sterile physiological saline;
Local wounds after operation can be bandaged with pressure or cold compress with ice packs, but the pressure should not be too high to avoid damaging the surgical site. If there is bleeding and severe hematoma after operation, it is necessary for us to go to the hospital for follow-up in time.
