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 the rabies vaccine.
However, if you are very concerned, you may consider self-paying for the rabies vaccine series of four doses (which costs approximately several thousand New Taiwan Dollars).
2.
It is advisable for you to visit a surgical outpatient clinic at a regional hospital or higher to manage the wound.
Besides 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.
Feeding or approaching stray or wild animals is not recommended, as various research reports 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 conducted.

More Info

When it comes to cat scratches, especially on sensitive areas like the lip, there are several important considerations to keep in mind. While you mentioned that there was no significant bleeding and only a minor abrasion, it’s crucial to monitor the injury closely for any signs of complications.

First and foremost, even minor injuries can become infected, particularly when they occur in areas that are frequently exposed to bacteria, such as the mouth. Cat scratches can introduce bacteria from the cat's claws or saliva into the wound. Therefore, it is essential to keep the area clean. You can gently wash the affected area with mild soap and water, and then apply an antiseptic ointment to help prevent infection.

Since you have received a tetanus shot within the last five years, you are likely protected against tetanus, which is a good thing. However, if you notice any signs of infection, such as increased redness, swelling, warmth, or pus coming from the wound, you should seek medical attention promptly. Infections can escalate quickly, and early intervention is key to preventing more serious complications.

Additionally, be aware of any systemic symptoms that may arise. If you develop a fever, chills, or feel generally unwell, these could be signs of a more serious infection that requires immediate medical evaluation. Cat scratch fever, caused by the Bartonella henselae bacteria, is another potential concern, although it typically presents with more systemic symptoms such as swollen lymph nodes, fever, and fatigue.

In terms of wound care, it’s advisable to avoid picking at the scab or the area around the scratch, as this can introduce more bacteria and lead to infection. Keeping the area moisturized can also promote healing, but be cautious not to overdo it, as excessive moisture can also lead to maceration of the skin.

If the scratch does not show signs of improvement within a few days, or if you have any concerns about the healing process, it would be wise to consult a healthcare professional. They may recommend a topical antibiotic or, in some cases, oral antibiotics if there is a significant risk of infection.

In summary, while a minor cat scratch on the lip may not seem serious, it is essential to monitor the wound for signs of infection, maintain proper hygiene, and seek medical advice if any concerning symptoms develop. Your previous tetanus vaccination is a positive factor, but vigilance is key to ensuring a smooth recovery.
