Pencil puncture wounds should be rinsed with saline and hydrogen peroxide, followed by routine disinfection of the wound, and depending on the depth of the wound, a decision should be made on whether or not to inject tetanus.
Pencil puncture wounds should first be rinsed with saline, and if the wound is deep, hydrogen peroxide should also be used. Afterwards, it should be routinely disinfected with povidone-iodine.
If the puncture wound is deep and prone to an anaerobic environment, an injection of tetanus antitoxin, or tetanus immunoglobulin, is also needed to prevent infection by Clostridium tetani.
If there is secondary bacterial infection, it can be treated with topical antibiotic medications such as erythromycin ointment and fusidic acid cream. If necessary, you can combine oral anti-infective drugs, such as amoxicillin, cefadroxil and so on.
Pencil puncture is recommended to go to the hospital for examination, according to the specific circumstances of the treatment as prescribed by the doctor.
