What is the reason for the slow wound healing after operation?

Surgery is a surgical department, and most patients treat diseases through surgery. Postoperative wound recovery is one of the keys to disease rehabilitation. Why is the wound healing slow? The following is the reason why I sorted out the slow healing of postoperative wounds. I hope it works for you.

The reason of slow wound healing after operation is 1. Age: The older you get, the slower the wound will heal. This is related to the comprehensive factors of the elderly.

2. Nutrition: Lack of protein, vitamins and trace elements can not provide necessary nutrition for tissue regeneration, which will delay wound healing. Trace elements related to wound healing include copper and zinc, and vitamins include vitamin A, vitamin C and vitamin E, etc. These substances are generally not lacking in normal people. However, the demand for wound healing is much higher than usual, and the patient's appetite is bad and food is less, which will also cause the demand to exceed the supply. It is very important to strengthen nutritional support after operation. Especially for patients who can eat, they should eat a digested high-protein and high-calorie diet.

3. Infection: There is a lot of exudate when the wound is infected, which will split the healed wound or stitched wound, or spread the infection and aggravate the injury.

4. Local blood circulation: On the one hand, local blood circulation ensures the oxygen and nutrition needed for tissue regeneration, on the other hand, it also plays an important role in absorbing necrotic substances and controlling local infection. Therefore, it is necessary to promote blood circulation through appropriate activities after operation.

5. Blood sugar: Diabetes patients have more sugar in their blood, accompanied by vascular diseases, which will affect wound healing. Controlling blood sugar before and after operation will directly affect the degree of wound recovery.

6. Smoking: The combination of carbon monoxide and hemoglobin in smokers' blood circulation reduces their ability to transport oxygen. Nicotine can contract peripheral blood vessels and affect wound healing.

7. Psychological factors: Psychological stress affects the function of neuroendocrine immune system and slows down wound healing.

8. Postoperative complications: Complications such as thrombosis, pneumonia, peritonitis and postoperative intestinal obstruction have a direct impact on wound healing.

9. Drugs: immunosuppressants, cell inhibitors and hormone anticoagulants have direct negative effects on wounds, which will inhibit cell proliferation and affect tissue repair.

10. ionizing radiation: radiation will destroy cells, damage small blood vessels, inhibit tissue regeneration and prevent scar formation.

Normal healing time after anorectal surgery

1. Hemorrhoids

In general, after hemorrhoid surgery, it usually takes 7 to 10 days for the affected area to gain weight and recover in about 30 days. Different people have different constitutions.

2. Anal fissure

The recovery time after operation depends on the patient's physique. Thread-hanging method was used in the operation. Generally, after 1 ~ 2 weeks, the thread will automatically break, and then the dressing will be changed to promote wound healing. Usually, the symptoms will obviously improve in a month or so. A few people have not been offline for two weeks and can only be removed by doctors, which may prolong the recovery time.

3. Anal fistula

It can be divided into high anal fistula, low anal fistula and complex anal fistula, and the low anal fistula usually recovers about 30 days after operation. The repair time of high complex anal fistula generally takes about 50 days. If the patient is allergic to certain drugs and has symptoms such as eczema during the recovery period, it will delay the wound healing.

4. Perianal abscess

The recovery time is different according to the patient's own situation and the size of abscess cavity. Smaller abscesses may take one to two weeks to heal, while larger abscesses take about two to four weeks to heal. Generally speaking, the wound of perianal abscess has not healed for more than one month after operation, which belongs to poor healing.

Common causes of slow wound healing

1. Infection: This is an important reason that affects wound healing. Infection can lead to tissue necrosis, vascular embolism, hypoxia and neutrophil release protease, which affects wound healing.

2. Improper wound treatment: poor postoperative drainage, postoperative wound stimulated by foreign body, or rough operation, incomplete removal of necrotic tissue, improper dressing change after operation, improper hip bath after operation, etc. Will cause slow wound healing.

3. The patient's physical factors: the patient's own chronic diseases such as malnutrition, physical weakness, anemia and vitamin deficiency can lead to slow wound healing.

Experts remind: If the patient's wound does not heal for a long time, or the wound inflammation, edema and pain continue unabated, he should go to the hospital for reexamination as soon as possible.

How to eat 1 balanced nutrition and supplement protein: Increasing the intake of protein in the diet can promote wound healing and reduce the chance of infection. Protein-rich foods include all kinds of meat, milk and eggs. In addition, the lack of lipid will lead to slow wound healing and affect recovery. Fish oil is rich in fatty acids, which has anti-inflammatory effect and is beneficial to wound healing. It can be taken in moderation.

2 zinc supplementation: zinc deficiency will weaken the function of fiber cells, slow down wound healing and be susceptible to infection. Zinc supplementation can improve skin regeneration ability, accelerate healing and reduce skin inflammation, herpes, rash and other skin diseases. Zinc mainly exists in peanuts, oysters, apples and other foods.

Vitamin A can maintain the normal structure and function of epithelial cells and promote wound healing. It mainly exists in carrots, animal livers, tomatoes and other foods. Increasing the intake of vitamin C can enhance the body's disease resistance and promote wound healing. Vitamin C mainly exists in fresh vegetables and fruits, among which jujube and pepper are treasure houses of vitamin C..
