Introduction

Keeping the wound clean and sterile helps prevent infection. Contaminants such as dust and bacteria can easily cause infection, affect normal wound healing, and thus increase the likelihood of scarring. The wound should be promptly rinsed with buffered physiological saline or clean water as directed by a physician after injury, to remove surface contaminants. During the wound healing process, regularly clean the skin around the wound to prevent accumulation of secretions.

To prevent scarring after a wound, it is important to perform proper wound management and care, such as cleaning and disinfecting the wound, appropriately protecting the wound, avoiding sun exposure and ultraviolet radiation, refraining from scratching, and using anti-scar medications. The details are as follows:

1. Wound Cleaning and Disinfection

Maintaining a clean and sterile wound helps prevent infection. Contaminants such as dust and bacteria can easily cause infection, interfere with normal wound healing, and increase the likelihood of scarring. Immediately after injury, the wound should be rinsed with buffered physiological saline or clean water as directed by a physician to remove surface debris. During the healing process, regularly clean the skin surrounding the wound to prevent accumulation of secretions.

2. Appropriate Wound Protection

Properly protecting the wound can reduce external irritation and promote wound repair, thus decreasing the probability of scarring. Choose breathable dressings that do not exert excessive pressure on the wound as advised by a physician. Avoid vigorous friction or damaging the newly formed tissue, as this may interfere with wound healing.

3. Avoid Sun Exposure and Ultraviolet Radiation

Ultraviolet light increases melanin production, leading to pigmentation and affecting the uniformity of skin color during the healing process. Apply sunscreen when going outdoors and wear long-sleeved clothing to cover the affected area.

4. Avoid Scratching

Itching may occur during the healing process. However, scratching may damage newly formed skin tissue, cause reinjury to the wound, delay healing, and increase the risk of scar formation. If the itching is unbearable, gently tapping the skin around the wound may help relieve the discomfort.

5. Use of Anti-Scar Medications

Anti-scar medications can inhibit excessive proliferation of fibroblasts and reduce inflammatory reactions, thereby helping to prevent scar formation. As directed by a physician, begin applying medications such as asiaticoside cream, sodium heparin cream, or vitamin E cream after the wound has healed to help soften existing scars.

During the recovery period, it is also recommended to improve your diet by increasing intake of foods rich in protein and vitamin C, such as chicken, fish, fresh fruits, and vegetables.

What Fruits Should Be Eaten After a Miscarriage (Small Confinement Period)?

The “small confinement” period after miscarriage refers to the time during which a woman’s body recovers following a miscarriage. Generally, during this period, patients may consume moderate amounts of fruits such as apples, cherries, grapes, papayas, and blueberries. Additionally, mild fruits like strawberries and longans may be consumed in small quantities. In daily life, it is also advisable to avoid cold or cooling fruits (e.g., refrigerated or chilled fruits) and instead consume fruits at room temperature.
