If a very fine splinter is stuck in the finger, it can be removed directly if the location is not deep; if the location is deeper, it is recommended to consult a doctor in time and remove it under the guidance of a professional physician. 1. Superficial trauma: If the splinter is shallow and visible to the naked eye, it can be removed on its own and then sterilized with iodine povidone and observed regularly. 2. Deep trauma: If the location of the splinter is relatively deep and cannot be removed by oneself, one should consult a doctor in time and remove the foreign body under the guidance of a professional physician, and then decide whether it is necessary to carry out traumatic treatment or local disinfection and bandaging according to one’s personal situation, and if necessary, one can be inoculated with tetanus vaccine. If secondary infection occurs after the finger is stabbed, with pus, redness, swelling, pain and other symptoms of the finger, oral antibiotics such as cefixime and amoxicillin should be taken under the guidance of a medical professional to prevent and treat the infection.
