If the splinter is shallow, you can remove it by yourself, but if it is too deep, you need to go to the hospital for treatment. 1. If the thorn is shallow and the end of the thorn is exposed outside the skin, you can use tweezers or a sterilized needle to remove the thorn; or use transparent tape to stick on the affected area, and then in the direction of the thorn, quickly tear off the transparent tape, which can often bring out the thorn. After removal the wound is sterilized with iodophor to prevent infection. After success, it needs to be sterilized with topical alcohol or iodine vapour to prevent infection. 2. If the above measures fail to remove the stinger, or if the stinger is stuck deeper into the skin and the end is not inside the skin, failure to remove it in time may induce inflammation, with redness, swelling, heat and pain. At this time, you can go to the hospital, the doctor cut the skin, with professional instruments to remove the bandage, and change the medicine regularly. If infection occurs, you need to timely cut and drain the pus, while taking amoxicillin, cefaclor and other antibiotics to prevent infection. Note that after taking the puncture need routine injection of tetanus antitoxin to prevent tetanus.
