Introduction

In general, if the symptoms of paronychia are mild, applying iodophor may lead to spontaneous healing. However, if the condition is severe, it may not resolve on its own and medical advice should be followed for treatment. Paronychia refers to inflammation of the tissue around the nail, often caused by bacterial infection. In its early stages, when symptoms are mild, paronychia may only present as slight redness, swelling, and pain in the tissue surrounding the nail.

Generally, if the symptoms of paronychia are mild, applying iodophor may lead to spontaneous healing. However, if the condition is severe, it may not resolve on its own. If used, it should be under medical guidance. Detailed explanation is as follows:

Paronychia refers to inflammation of the tissues surrounding the fingernails, often caused by bacterial infection. In the early stages of paronychia when symptoms are mild, characterized only by slight redness, swelling, and pain around the nail without pus or discharge, iodophor can exert antibacterial effects and help control the infection. Applying iodophor several times daily for disinfection, maintaining local cleanliness and dryness, and avoiding pressing or rubbing the nail area may allow the inflammation to gradually subside and achieve spontaneous recovery.

If paronychia worsens with significant pus formation or an abscess has developed, applying iodophor alone may not be sufficient to achieve a cure. At this stage, the antibacterial effect of iodophor is relatively limited and may fail to fully control the localized infection, potentially leading to further deterioration. In such cases, prompt medical attention is necessary, and doctors may perform incision and drainage to remove the pus as part of the treatment.

In daily life, to prevent the occurrence or recurrence of paronychia, it is important to maintain clean and dry skin around the nails and avoid cutting the nails too short or too deeply.

Can iodophor be used to disinfect pressure ulcers?

In general, pressure ulcers can be disinfected with povidone-iodine. If you need to use povidone-iodine for disinfection, it is recommended to consult a doctor's advice. Pressure ulcers occur due to prolonged localized pressure on the body, leading to circulatory impairment and tissue ischemia and hypoxia, resulting in ulceration and necrosis. Such wounds are prone to harboring large amounts of bacteria. Povidone-iodine has a broad-spectrum antimicrobial effect and can rapidly kill various bacteria, fungi, viruses, and other microorganisms.
