Post-Cryotherapy Care for Warts: Managing Blisters and Wound Healing

After cryotherapy for a viral wart, the blister has burst, and the area has also come off?

Hello Doctor, I have developed viral warts on my hands and feet.
I have undergone several cryotherapy sessions since April 30, with the most recent one on June 11.
After the cryotherapy, blisters formed, and the doctor advised me to sterilize a needle and puncture the blisters, then apply an anti-inflammatory ointment.
As a result, on June 17, the dead skin fell off, but after it came off, a new wound appeared, exposing the dermis, and it has been bleeding or oozing fluid.

1.
How should I care for this wound?
2.
Will covering the wound with gauze slow down the healing process?
3.
After cryotherapy, what precautions should I take to prevent infecting my 4-month-old baby?
4.
Since I also have warts on my hands, can the skin that comes into contact with water during bathing get infected?
5.
I also have warts on my feet; how should I clean them?
6.
Can I apply salicylic acid to the wound since it is currently open?
Thank you for your response.

1.
For wound care, you can use povidone-iodine for disinfection, followed by saline solution for further cleaning, and then apply an antibiotic ointment.
Finally, cover the wound with gauze or an adhesive bandage.

2.
Using breathable gauze will not hinder wound healing; however, if there is excessive exudate that makes the gauze damp, you should change the dressing.

3.
If ongoing treatment is maintained, it is unlikely to spread to other areas or to other individuals.

4.
Normal cleaning is sufficient.

5.
Salicylic acid is not suitable for wound care.
Wishing you peace and happiness.

Post-cryotherapy care for warts is crucial to ensure proper healing and to prevent complications such as infection or further irritation. Here’s a comprehensive guide on how to manage blisters and wounds after cryotherapy, particularly in your case where you have experienced some complications.

1. Wound Care: After cryotherapy, it is common for blisters to form as the skin reacts to the freezing treatment. If a blister has formed, it is generally advisable to leave it intact to protect the underlying skin. However, if the blister is large and painful, your doctor may have advised you to drain it using a sterilized needle. If you have already done this and the blister has burst, it’s important to keep the area clean. Gently clean the wound with mild soap and water, then apply an antiseptic ointment. Cover the area with a sterile bandage or gauze to protect it from dirt and bacteria.

2. Healing Process: Covering the wound with a bandage or gauze will not necessarily slow down the healing process; in fact, it can help protect the area from infection and further irritation. However, it’s essential to change the dressing regularly, especially if it becomes wet or soiled. If you notice excessive bleeding or the wound continues to ooze, consult your healthcare provider for further evaluation.

3. Preventing Transmission: To prevent spreading the virus that causes warts to your baby, practice good hygiene. Wash your hands thoroughly after touching the affected areas and avoid direct contact with the warts. It’s also advisable to keep the warts covered when you are around your baby. Avoid sharing towels, razors, or any personal items that may come into contact with the warts.

4. Bathing Precautions: When washing, be cautious around the areas with warts. Use a gentle soap and avoid scrubbing the warts or any open wounds. If you have warts on your hands, consider using gloves while bathing to minimize the risk of spreading the virus to other parts of your body or to your baby.

5. Cleaning the Feet: For warts on your feet, ensure that you wash them thoroughly but gently. Avoid soaking your feet for extended periods, as this can soften the skin and potentially lead to further irritation. After washing, dry your feet completely, especially between the toes, and apply any recommended topical treatments as directed by your healthcare provider.

6. Use of Salicylic Acid: Salicylic acid is a common treatment for warts, but it should not be applied to open wounds or broken skin. Since you currently have a wound that is bleeding or oozing, it is best to avoid using salicylic acid until the area has healed completely. Once the skin has closed and is no longer open, you can discuss with your healthcare provider about resuming salicylic acid treatment for the warts.

In summary, proper wound care after cryotherapy is essential for healing and preventing complications. Keep the area clean and protected, practice good hygiene to prevent spreading the virus, and consult your healthcare provider if you have any concerns about the healing process or if the wound does not improve. Always follow your doctor's specific instructions regarding wound care and treatment options.
