Cat scratch on the lip?

Hello, doctor.
I would like to ask about a cat scratch on the inside of my lip.
There is no obvious bleeding, but the skin is broken.
I received a tetanus shot within the last five years.
Is there anything else I need to pay special attention to? Thank you!

Dear Mr.
Kai:
1.
Your issue pertains to a cat scratch; it is recommended to observe or confine the cat for 10 days.
If the cat becomes ill or dies, you should consider receiving a rabies vaccination.
Of course, if you are very concerned, you may consider paying out of pocket for the rabies vaccine, which consists of four doses (totaling approximately several thousand New Taiwan Dollars).
2.
It is advisable for you to visit a surgical outpatient department at a regional hospital or higher to manage the wound.
In addition to the risk of rabies, animal bites are more commonly associated with aerobic or anaerobic bacterial infections, as well as cat scratch fever; sometimes antibiotic treatment may be necessary.
If you still have questions, it is recommended to discuss them with your family physician.
3.
It is not advisable to feed or approach stray or wild animals, as various studies have specifically pointed this out.
Clinically, we often encounter cases where patients have been bitten or scratched due to feeding or approaching stray animals.
Of course, if it is a domestic cat, regular check-ups and necessary vaccinations should also be performed.

More Info

When dealing with a cat scratch on the lip, especially if it involves broken skin, there are several important considerations to keep in mind. First and foremost, it’s essential to assess the severity of the scratch and monitor for any signs of infection. Although you mentioned that there is no obvious bleeding, the broken skin can still be a potential entry point for bacteria, which could lead to an infection.

Immediate Care Steps
1. Clean the Wound: The first step is to thoroughly clean the area. Use mild soap and water to gently wash the scratch. This helps remove any dirt or bacteria that may have been introduced during the scratch.

2. Disinfect: After cleaning, apply an antiseptic solution, such as hydrogen peroxide or an alcohol-free antiseptic wipe, to the area. This further reduces the risk of infection.

3. Monitor for Infection: Keep an eye on the scratch for any signs of infection, which may include increased redness, swelling, warmth, pus, or if the area becomes increasingly painful. If any of these symptoms develop, it’s important to seek medical attention promptly.

4. Avoid Irritation: Since the scratch is on the lip, be cautious about irritating the area further. Avoid spicy foods, acidic foods, or anything that might cause discomfort.

Tetanus Consideration
You mentioned that you received a tetanus shot within the last five years. Generally, the tetanus vaccine is effective for about ten years. However, if you have any concerns about your vaccination status or if the scratch was particularly deep or contaminated, it’s a good idea to consult with a healthcare provider. They can assess whether a booster is necessary.

When to Seek Medical Attention
You should seek medical attention if:
- The scratch shows signs of infection as mentioned earlier.

- You experience significant pain or swelling that does not improve.

- You notice any systemic symptoms such as fever, chills, or malaise.

- The scratch does not begin to heal after a few days.

Additional Considerations
- Cat Scratch Disease: While most cat scratches are minor, it’s worth noting that cats can carry a bacterium called Bartonella henselae, which can cause Cat Scratch Disease (CSD). Symptoms of CSD may include swollen lymph nodes, fever, and fatigue. If you develop these symptoms after the scratch, it’s important to consult a healthcare provider.

- Allergic Reactions: If you notice any unusual reactions, such as hives or swelling beyond the area of the scratch, this could indicate an allergic reaction, and you should seek medical help.

Conclusion
In summary, while a cat scratch on the lip may not seem serious, it’s crucial to take proper care of the wound to prevent infection. Given your recent tetanus vaccination, you are likely protected, but always err on the side of caution and consult a healthcare professional if you have any doubts or if symptoms arise. Taking these steps will help ensure that your scratch heals properly and without complications.
