Many post-operative patients, “talk about sarcoid”, because some people were repaired again because of this. After going through the pain of surgery, it is easy to relax, but it is hard to avoid worrying and fearing when you have to move the knife and cut again. What is a sarcoma? Do sarcomeres have a role to play? When do they need to be trimmed? Is there a way not to trim? Here are some answers.
I. What is a bud?
The fresh meat in the process of wound repair, the “meat buds” in our mouth, in fact, refers to “granulation tissue”. Granulation tissue refers to the process of tissue damage, to replace the necrotic tissue and the formation of new capillary-rich infantile stage of fibrous connective tissue. Granulation tissue is an essential tissue in any wound repair process. To the naked eye, the surface of granulation tissue is fine-grained, bright red, soft and moist, easy to bleed when touched without pain, and resembles tender flesh, hence the name “granulation”.
Second, the characteristics of the granulation is very easy to bleed but not painful.
The granulation tissue often contains a certain amount of edema fluid, so it looks fresh and tender, and sometimes it is elevated with the plane of the wound. The granulation tissue contains abundant capillaries with thin walls, so there may also be a small amount of blood oozing when gently touched during the dressing change. However, the granulation tissue does not contain nerve fibers, so even if touched, the pain is not obvious.
Third, the role of granulation picks up.
1, anti-infection to protect the wound.
2, filling wounds and other tissue defects.
3, mechanization or wrapping necrosis, thrombus, inflammatory exudate and other foreign bodies.
IV. End of granulation forming scar.
Granulation tissue can begin to appear within 2 to 3 days after tissue injury to fill wounds or mechanize foreign bodies. Over time, granulation tissue matures in the order of its growth. Water absorption decreases gradually after maturation, inflammatory cells decrease and gradually disappear, and capillaries become occluded and decrease in number. Eventually the granulation tissue matures into fibrous connective tissue and transforms into scar tissue.
V. Abnormal granulation overgrowth.
There are times when the granulation is also edematous and overgrown. It appears to protrude from the wound, bleeds extremely easily, and is extraordinarily fragile. This can often be seen in some postoperative wounds of anal diseases. This is an abnormal granulation, called “pterygium” in Chinese medicine, which can cause the wound to not heal or to heal slowly, or in some cases to form a false healing. The main reasons for this are
1, oversized wounds, such as large abscesses and post-operative trauma of anal fistulae.
2. excessive wound tension, such as post-operative trauma of anal fissures and circumferential mixed hemorrhoids.
3, weaker individuals.
4, blind use of drugs to promote wound healing.
5.Local impermeability, humidity, and excessive use of oily drugs.
VI. Treatment of abnormal granulation Pruning is not the only method.
In order to promote faster and better healing of the wound, abnormal granulation needs to be treated.
1. Compress oil gauze strips when changing medication on larger wounds.
2.Clean, change the excipients in time depending on the amount of secretions and try to keep the area relatively dry.
3.Use 20% concentrated sodium chloride to wet dress the wound.
4.Concentrated saline or alum water sitz bath.
5.Protruding or turning out the trauma of the granulation will need to be trimmed in time.
