For people who have had a biopsy, the next day when removing the gauze, you should wash your hands and then tear off the tape by hand, remove the outer gauze, and then use sterile forceps to remove the inner gauze. Currently, in clinical practice, when replacing gauze, one should wash hands first, tear off the adhesive tape holding the gauze, then remove the outer gauze and put it into the dirt tray; for the inner gauze, one needs to use sterile tweezers to remove it, and then disinfect the wound after checking the wound, disinfecting the wound for 2~3 times, and then cover it with a new dressing. If the wound has healed, it is only necessary to remove the original gauze and sterilize the skin. For people who have undergone tissue removal biopsy, it is important to keep the incision site clean and dry, change the dressing regularly to prevent bacterial infections, eat a light diet, and pay attention to rest to facilitate the recovery of the condition. To remove the gauze on the second day after the biopsy, you need to go to the hospital to be operated by a professional physician.
