A doctor removes sutures by snipping the thread near the knot and gently pulling the string loose, according to WebMD. Patients should never remove sutures at home or without a doctor's permission. Some thread dissolves on its own over time and is not manually removed.
Removing stitches normally causes no pain, but WebMD warns that it can feel uncomfortable or strange. Stitches can remain in place for a few days to several weeks depending on the severity of the injury and the duration of the healing process. Surgical thread is made out of silk, nylon or other materials. If the thread breaks or pops, the patient should return to the doctor immediately.
WebMD recommends stitches for a cut that is deep and jagged or that bleeds profusely and continuously as well as for a cut located where it may leave a visible scar or a cut that feels numb. Doctors do not recommend sutures for certain types of serious wounds, such as punctures.
To begin the suturing process, the doctor begins by numbing and cleaning the area, then removing any debris or foreign objects still lodged in the wound. They remove any dead issue and pull the edges of the cut together before stitching the injury. The patient must then keep the area as dry and clean as possible and apply an antibiotic ointment regularly to prevent infection.
