Open the tape and gauze. When there is adhesion, be careful not to uncover the gauze and disinfect it locally. If there is a drainage strip, you can take it out with tweezers, observe the situation in the drainage cavity, clean the drainage cavity with physiological saline cotton ball or hydrogen peroxide, and place a new drainage strip or gauze. Wrap sterile gauze outside until the drainage cavity is clean and there is no secretion, so there is no need to place drainage strips. Let it heal itself. I hope my suggestion is helpful to you and I hope it will be adopted. Beautiful mood team wishes you health!
