Introduction

Under normal circumstances, whether it is advisable to disinfect a wound with povidone-iodine daily depends on the specific condition of the wound. When the wound is contaminated, it may be beneficial to disinfect it daily with povidone-iodine. However, if the wound is in the healing stage, daily disinfection with povidone-iodine may not be recommended. Before using povidone-iodine for disinfection, it is advised to first clean the wound with normal saline or medical alcohol.

　　Under normal circumstances, whether it is beneficial to disinfect a wound with povidone-iodine daily depends on the specific condition of the wound. When the wound is contaminated or healing poorly, disinfecting with povidone-iodine daily is better. If the wound is currently healing, daily disinfection with povidone-iodine may not be advisable. If experiencing any physical discomfort, timely medical consultation is recommended. Detailed analysis is as follows:

　　When the wound is contaminated, such as being dirtied by soil or dust, or when the wound has already shown signs of infection, such as redness, swelling, intensified pain, or when healing is poor with conditions like cracking or tissue necrosis, disinfecting the wound daily with povidone-iodine can effectively kill surface bacteria, prevent further infection, create a relatively clean environment for wound healing, and help promote recovery. In these cases, disinfecting daily with povidone-iodine is appropriate.

　　If the wound is clean and fresh, with no obvious bleeding or exudate and is in the normal healing process, disinfecting with povidone-iodine daily may overly irritate the wound, damage newly formed tissue cells, and interfere with the normal healing process. At this stage, the wound requires a relatively stable environment to promote tissue repair and regeneration, and excessive disinfection may have counterproductive effects. Therefore, when the wound is already clean, shows no signs of infection, and healing has begun, daily use of povidone-iodine disinfection should be avoided.

　　Before using povidone-iodine for disinfection, it is recommended to first clean the wound with normal saline or medical alcohol to remove dirt, blood, and other contaminants from the wound surface, thereby enabling povidone-iodine to work more effectively.

When to remove stitches after appendicitis surgery?

The timing for suture removal after appendectomy mainly depends on the surgical method and wound healing. Most patients have their stitches removed 5 to 10 days after surgery, although the exact timing should be adjusted according to individual circumstances. In daily life, it is important to keep the wound clean and dry before suture removal, avoiding contact with water and friction to prevent infection. After suture removal, strenuous exercise and activities involving abdominal strain should be avoided in the short term to minimize tension on the wound.

What are the dietary principles after polypectomy of the intestine?

In general, after removal of intestinal polyps, the intestine is left with a small wound surface, and dietary management is a key factor in preventing bleeding and promoting healing. The overall principle can be summarized as starting with a liquid diet, progressing to a semi-liquid diet, then soft foods, and finally returning to a regular diet. Throughout this period, it is essential to adhere to a low-residue, low-fiber, mild, and frequent small-meal regimen. If persistent bloating, cramping pain, or rectal bleeding occurs, eating should be stopped immediately and the surgeon should be contacted.
