Introduction
In general, if you puncture your finger while washing seafood, you should immediately clean and disinfect the wound, remove any foreign objects, apply medication, provide local wound care, and seek medical attention promptly. Additionally, individuals with underlying medical conditions such as diabetes, hyperthyroidism, or hypothyroidism should be especially cautious after such injuries and are advised to seek professional medical help early to prevent complications.

Generally, if a finger is punctured while washing seafood, it can be managed by immediately cleaning and disinfecting the wound, removing any foreign objects, medical intervention, local care, and seeking timely medical attention. Specific measures are analyzed as follows:

1. Immediate Cleaning and Disinfection

After the injury, the wound should be flushed immediately with running clean water to remove residual seafood juices and debris from the surface. After rinsing, disinfect the wound and surrounding skin with iodophor or medical alcohol to kill potential bacteria and parasites, thereby reducing the risk of infection. Handle gently during the process to avoid excessive squeezing, which may push foreign matter deeper into the wound.

2. Removal of Foreign Objects

If foreign bodies such as shell fragments or spines remain in the wound, they should be carefully removed using sterilized tweezers or a needle tip to ensure complete clearance. Maintain hand stability during removal. If the object is deeply embedded or difficult to extract, do not force the procedure, as this may worsen tissue damage.

3. Medical Intervention

To prevent infection, topical antibiotics such as mupirocin ointment or erythromycin ointment may be applied under medical guidance. If allergic reactions occur, medications such as cetirizine hydrochloride tablets, fexofenadine hydrochloride tablets, or loratadine capsules can be used. Before using any medication, confirm that there are no contraindications for personal use.

4. Local Wound Care

After treatment, cover the wound with sterile gauze or a bandage to keep it dry and clean, avoiding contact with water and contaminants. Protect the injured hand during daily activities to prevent compression or friction on the wound. Change dressings regularly and monitor the healing progress.

5. Seek Timely Medical Attention

Seek immediate medical help if symptoms such as redness, swelling, pus discharge, increased pain, fever, numbness of the finger, or spreading swelling occur. Punctures from seafood carrying specific bacteria may lead to severe infections—do not delay treatment.

In addition, individuals with underlying conditions such as diabetes, hyperthyroidism, or hypothyroidism should be especially cautious after such injuries. It is advisable to seek professional medical assistance early to prevent complications.
