Managing Wound Care After a Fishing Accident: Tetanus and Infection Concerns

Cutting your hand while fishing?

Hello, Doctor: I accidentally scraped off a layer of skin next to my nail with a hexagonal screw at the back of a boat while participating in a fishing activity.
Although I treated it with Betadine at the time, I did not closely check if the screw was rusty.
Seven hours later, I went to a clinic for a tetanus shot and took a three-day course of antibiotics prescribed by the doctor.
I would like to ask: 1.
The clinic nurse advised me to cover the wound with a synthetic skin, but I read online that tetanus is caused by anaerobic bacteria.
Will this make me more susceptible to tetanus? 2.
After the wound heals, will the tetanus bacteria remain in my body and cause illness? I am particularly concerned about cellulitis and tetanus due to the injury from the screw at the seaside fishing area.
Thank you, Doctor, for your thoughtful response.

Hello! There's no need to worry since you've received a tetanus shot.
Clean the wound with saline solution, apply antibiotic ointment, and change the dressing daily.
Avoid contact with tap water, and it should heal in a few days.
Take care! Changhua Hospital cares about you!

More Info

In managing wound care after a fishing accident, particularly one involving a puncture or scrape from a potentially rusty object, there are several important considerations regarding tetanus and infection risks.

Firstly, it’s commendable that you took immediate action by cleaning the wound and seeking medical attention for a tetanus shot and antibiotics. Tetanus is caused by the bacterium *Clostridium tetani*, which is an anaerobic organism, meaning it thrives in environments with little to no oxygen. This is why wounds that are deep, dirty, or caused by objects like rusty nails can pose a higher risk for tetanus infection. However, the fact that you received a tetanus booster shot within a reasonable time frame (7 hours post-injury) significantly reduces your risk of developing tetanus.

1. Use of Artificial Skin: The use of artificial skin or a wound dressing can be beneficial in protecting the wound from external contaminants and promoting healing. While it is true that anaerobic bacteria can thrive in certain conditions, using a sterile dressing does not inherently increase your risk of tetanus. In fact, keeping the wound covered can help prevent infection by keeping out dirt and bacteria. It is essential, however, to ensure that the dressing is changed regularly and that the wound is kept clean and dry.

2. Tetanus Persistence: Once you receive a tetanus vaccine or booster, the body develops immunity to the toxin produced by *C. tetani*. The bacteria itself does not remain in the body after vaccination; rather, the immune system is primed to respond if it encounters the toxin in the future. Therefore, you do not need to worry about the tetanus bacteria lingering in your body after the wound heals.
Regarding your concerns about cellulitis (a skin infection) and other infections, it is crucial to monitor the wound for signs of infection, which can include increased redness, swelling, warmth, pain, or discharge. If you notice any of these symptoms, it is advisable to seek medical attention promptly. The antibiotics you received should help prevent bacterial infections, but if the wound does not improve or worsens, further evaluation may be necessary.

In addition to monitoring the wound, here are some general wound care tips:
- Keep the Wound Clean: Clean the wound daily with mild soap and water. Avoid using alcohol or hydrogen peroxide, as these can irritate the tissue and delay healing.

- Apply Antibiotic Ointment: After cleaning, applying a topical antibiotic ointment can help prevent infection.

- Change Dressings Regularly: Change the dressing at least once a day or whenever it becomes wet or dirty.

- Watch for Symptoms: Be vigilant for any signs of infection, such as fever, increased pain, or spreading redness.

- Follow Up: If you have any concerns about the healing process or if symptoms of infection arise, do not hesitate to return to your healthcare provider for further evaluation.

In summary, while your injury does pose some risk for infection and tetanus, your proactive measures and medical care significantly mitigate these risks. Continue to care for your wound properly, and keep an eye out for any signs of complications. If you have any doubts or concerns, consulting with a healthcare professional is always the best course of action.
