The nursing points after replantation of severed fingers are as follows: First, pay attention to avoid catching a cold at the surgical site. Patients can't smoke, and they can't smell secondary smoke. These factors will lead to spasm and stenosis of finger artery, affect the blood supply at the distal end of finger, and even lead to finger necrosis in severe cases. Second, after replantation of severed fingers, attention should be paid to keeping fingers fixed, reducing the tension of nerves and blood vessels, and checking the firmness of fixation every day to prevent thrombosis or movement.

Nursing measures: ① Early nursing measures: In the next three weeks, the key point is to prevent and control the occurrence of infection, so as to promote the healing of soft tissue. Can be used for infrared ray, ultrashort wave and ultraviolet ray physiotherapy, accelerates blood circulation, eliminates swelling, and is beneficial to wound healing at an early date. ② Mid-term nursing measures: 4~6 weeks after operation, the key point is to prevent joint injury, muscle tendon adhesion and muscle ginger contraction. Active activity, PPM adjuvant therapy. But the action should be gentle, so as not to damage the tissue being repaired. ③ Postoperative nursing measures: 6-8 weeks after operation, the key point is to speed up and improve the recovery of nerve function, soften scars as much as possible, especially reduce adhesion, and strengthen exercise and sensory training.

After trauma and surgery, we need a lot of protein to promote wound healing, encourage eating more high-protein foods such as chicken, fish, meat, eggs and bean products, pay attention to supplementing vitamins, iron and calcium, correct anemia, enhance resistance and promote fracture healing. Also eat more fresh fruits and vegetables, drink more water, and prohibit eating stimulating foods such as sour and spicy food.

Most of the replanted limbs recovered certain or quite ideal functions. In some cases, although the amputated limb survived, unfortunately, the replanted limb was still useless and formed a heavy creature. The purpose of replantation of severed limbs is to restore the function of injured limbs and make patients work as soon as possible. Therefore, on the basis of the broken limb, the injured limb must be restored to its maximum function.

From the fifth day after operation, the patient was instructed to actively exercise wrist joint, healthy interphalangeal joint and palm interphalangeal joint for 3 hours every day. On day 14 after operation, the patient practiced extracting or kidnapping sandbags. The weight of sandbags is 50- 100g. Continue to actively exercise patients' normal joints for 3 hours a day. On the 45th day after operation, the speed of passive movement should be slow and the strength should be gradually increased. When the limit angle is reached, keep it at 10-20min, and then slowly reduce the external force, so as to repeatedly stretch and buckle. The range of passive movement is increasing every day or week from small to large. The active actions of the patient's interphalangeal joints include palm, palm, opponent, fist and fist-making. Auxiliary use of rubber band nets, screws, nuts and other tools to train fingers, 6 hours a day.
