After plastic surgery, it should be noted that there will be some pain in the wound that day, but it will gradually decrease with the passage of time. Patients should not rush to take painkillers, because aspirin drugs will aggravate wound bleeding. 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. Once there is bleeding and severe hematoma after operation, you should go to the hospital for follow-up in time.
