If a rose thorn sticks to your hand, you must determine whether the rose thorn has broken off and whether it has remained inside the soft tissue of the skin. First of all, you can press the wound where the thorn was stabbed locally. If there is no needle-like sensation, just dull pain, there is usually no thorn inside, and you can disinfect it 2-3 times repeatedly with hydrogen peroxide and iodophor. If the piercing is very deep and there is dirt or other contaminants on the thorns of the rose, it is recommended to go to the hospital to inject tetanus antitoxin to prevent tetanus bacillus infection, and also to apply antibiotics for 2-3 days to prevent other bacterial infections as appropriate. If the thorns are found inside, you must go to the hospital and cut the skin after local anesthesia of the finger to find out the thorns of the rose, then give them to be removed and stitch up the wound.
