After a patient’s hand is pierced by a shrimp, the wound can be completely healed in 7-10 days after a standard dressing change. After being stabbed by shrimp, patients should promptly seek surgical consultation. If the wound is not deep and the contamination is not serious, a simple gauze bandage or band-aid can be used to protect the wound after local disinfection, and the wound should be changed at an interval of 3 days to observe the wound condition. If there is an increase in wound redness, swelling and pain, it should be removed promptly. If the wound is purulent, the wound should be widened, pus should be discharged and drained, and the wound should be treated with daily medication changes and oral anti-infective medication, and generally the wound will heal in about 7-10 days. If the wound is large, it should be thoroughly debrided and sutured. Depending on the patient’s history of tetanus vaccination, tetanus vaccination or tetanus antitoxin injection is given to prevent tetanus. In addition, patients should also pay attention to protecting the wound from water and avoiding wound contamination during the recovery period.
