Sticking your hand in a shrimp is likely to induce the risk of infection due to the fact that seafood can have a very high number of microbial bacteria on its surface, which are not treated in a timely manner. It can be treated by iodophor as well as tetanus antitoxin injection. 1. Apply povidone-iodine: When the patient’s hand is pierced by a shrimp, the wound must be rinsed with plenty of water, and the local area should be disinfected and cleaned with povidone-iodine and alcohol. This will prevent microorganisms and bacteria from entering the wound and infecting the area. 2. Injection of tetanus antitoxin: If the patient’s hand is more serious by the shrimp, and there is bleeding phenomenon, you can first squeeze the blood out of the surface, and then inject tetanus antitoxin to prevent tetanus infection. When the patient’s hand was shrimp after treatment, in an hour or two after the gradual reduction of symptoms, if the pain persists, and there is no sign of alleviation, do not rule out that the wound has been infected. It is recommended that the patient go to the local hospital in time for the relevant treatment, so as not to delay the condition.
