What Is a Soft Tissue Graft?

The original meaning of transplantation refers to moving a plant to another place for planting, and then extending it to an organ transplant that transfers a living body or part of a living body, such as transferring one person's liver instead of another person's liver, which is called liver transplantation. In software engineering, programs are often regarded as living organisms. Moving source code from one environment to another can also be called transplantation.

In information

If the new vector of the transplanted living body part is very different from the original vector, this transplant is generally called grafting, for example, grafting the branches of an apple tree to a peach tree.

Human transplantation is the transplantation of autologous or allogeneic cells, tissues and organs to a part of the body to restore the anatomical structure and function of the damaged organ or tissue.

Blood transfusion was the earliest cell transplantation, and later tissue transplants were developed, such as skin, mucosa, omentum, bone marrow, fat, fascia, muscle, tendon, blood vessel, nerve, bone and cartilage. Due to the development of microsurgery and immunosuppressive drugs, organ transplantation is progressing rapidly.

(A) points of postoperative care of skin transplantation:

The skin grafting limbs should be restricted to prevent skin movements from affecting survival and elevating the affected limbs. Keep the dressings clean and dry, and change them immediately if they become soiled. Inform patients not to scratch the wound, and sick children should be restrained with both hands. Observe the wound frequently. If pus or blood accumulates under the skin, it should be treated immediately.

(B) Nursing points of replantation of severed limbs:

1.Disinfection, isolation and infection prevention measures

The patients lived in a single room after the operation. The indoor air and utensils had to be disinfected. The room temperature was maintained at 20-25 degrees and the humidity was 50% -60%. There was special care to limit visits. Use antibiotics to prevent infection, but try to use intramuscular injection to prevent venous thrombosis.

2 Observe vital signs:

Measure body temperature, pulse, breathing and urine volume regularly, record the amount of fluid in and out for 24 hours, and observe whether there is insufficient blood volume and the occurrence of postoperative complications (especially acute renal failure).

3 Care of replanted limbs

1) Lift the limb and replant the limb to the level of the heart to ensure venous return.

2) Eliminate vascular spasm. Replanted limbs can be irradiated with lamps (light distance 30-45cm) within one week after operation to make the limb blood vessels dilate; smoking is strictly prohibited.

3) Observe the local circulation, if the skin color changes from ruddy to pale, indicating arterial and dysfunction or embolism; scattered ecchymosis of the skin, suggesting partial venous embolism; large or all dark purple skin, indicating that the vein is completely embolized. Within 10 days after surgery, the skin temperature should be measured every 1-4 hours. The skin temperature of the replanted limb should be 1-2 degrees higher than the normal side. If the skin temperature drops suddenly, the difference between the affected side and the healthy side is more than 3 degrees, which indicates arterial embolism. If the temperature decreases slowly, the distance is more than 3 degrees within 1-2 days. For venous embolism. Capillary filling time is less than 1 second, the skin is bruised, and the affected limb is swollen, which is a venous reflux disorder. If the capillary filling time is prolonged to more than 2 seconds, the skin is pale, cold, and dry, and the blood supply to the artery is insufficient. If the limb is swollen, the circumference of the limb should be measured frequently, and follow-up observation should be made to find the cause and treatment, otherwise it may cause limb necrosis.

4 Functional exercise

Provide health education to patients, explain the importance of early activities, and help develop exercise plans. From the day when the replantation survives, the affected limb maintains a functional position and is absolutely rested, but can be used for proper massage and muscle strengthening. After 3-4 weeks, the soft tissue has healed. After the external fixation is removed, the patient is instructed to make active movements in all directions of the affected joint. It can also be used for more powerful contracture and joint function traction for systematic rehabilitation training.

(Three) hair transplantation and its principle

Hair transplant is an autologous hair transplant. The principle is to extract healthy hair follicles in the back of the human body, separate them under special circumstances, and then transplant them to the patient's hair loss area.

Hair transplant surgery is currently the most effective method for treating hair loss, and one-time hair transplantation can achieve perfect results. There are two main methods of hair transplant surgery, which are FUT technology and FUE technology.
