What is Finger Reimplantation Surgery? Re-implantation of severed finger is a highly delicate surgery to reanastomose the completely or incompletely severed finger under the optical microscope, thoroughly clean and create the bone, tendon and vascular skin repair surgery, plus postoperative comprehensive treatment in all aspects, so as to make the finger survive and restore its certain function. Contraindications to surgery 1, suffering from systemic diseases, poor physical condition, or complicated with serious organ damage, not allow a long time for surgery should not be reimplanted. 2.The broken finger is accompanied by multiple fractures or serious soft tissue injuries. 3, the integrity of the finger vascular bed is severely damaged, such as finger severance caused by crush injuries, manifested as subcutaneous petechial hemorrhage on both sides of the finger, even if the blood vessels are connected, due to extensive blood seepage from the soft tissues, thrombosis, and re-implantation of the finger is still difficult to survive. 4. If the time limit for reimplantation exceeds too much and the tissue has been degenerated, it is not suitable for reimplantation. Without refrigeration, the severed finger ischemia 24 hours may still be reimplanted to survive, such as after the injury immediately after the refrigeration treatment, reimplantation time limit can be extended to more than 30 hours. However, the shorter the time of ischemia, the higher the survival rate of replantation, on the contrary, the longer the time of ischemia, the lower the survival rate of replantation. The success of replantation of amputated fingers is not only the success of surgery, but also closely related to the postoperative nursing work, including the temperature of the ward, the patient’s activity level and cigarettes have an effect on the vascularization of the replanted limb, which requires the nursing staff to be careful to communicate and patiently persuade the nursing staff that the smoking ban in the ward area is necessary because nicotine has an important effect on the vasculature, which can lead to necrosis of the amputated finger. Postoperative patients are kept warm with a baking lamp, and nurses will check the patient’s condition every half an hour to an hour to see whether the color of the finger end is red and whether the temperature of the finger end is normal, and if adverse symptoms are found, they will be dealt with immediately. Patients should also be instructed to perform functional exercises as early as possible, such as passive finger flexion and extension exercises, flexion and extension of the wrist and elbow joints, and abduction and internal rotation of the arm, three times a day, 20-30 groups at a time. Finger reimplantation prevention 1, how to stop bleeding correctly: can not use handkerchiefs, belts, leather tube and other bundles in the upper part of the wrist, so not only can not stop bleeding, but also aggravate the bleeding, and some even cause necrosis of the finger, because the upper part of the wrist does not stop bleeding, but only to prevent venous return to make more bleeding. The correct way to stop bleeding is: use clean cotton products in the bleeding part of the pressure bandage can be, both effective and reliable, and will not bring adverse consequences. 2.Prevent further contamination: the purpose is to make the wound not to be invaded by external bacteria. The correct method is: use sterilized dressing to wrap the wound, also can be used clean cotton products to wrap, must not be in the wound on the application of purple potion and other drugs, which will affect the doctor to correctly determine the injury. 3, to prevent injury to aggravate the injury: this refers to when the finger fracture, incomplete disarticulation, if not fixed, let it move freely can make the original uninjured vascular nerve injury. The correct method is to use a small wooden board, iron and other temporary fixed, so that there is also the role of pain.
