Finger reimplantation surgery is a kind of surgery mainly for some patients who have broken their fingers for a short period of time and the preservation of their fingers is still very good, this kind of surgery is still very simple in the treatment. But any surgery, the most critical step is the postoperative care steps, then how to care for the broken finger reimplantation surgery after surgery? 1, systemic care: the patient after a long period of trauma and surgery, blood loss, the operation should be supplemented with a sufficient amount of whole blood, postoperative close observation of the casualty’s skin color, blood pressure, pulse and peripheral venous filling degree, the initial determination of anemia, and do the routine blood tests and hematocrit, central venous pressure determination, if necessary, in order to take timely measures, high amputation, should pay attention to acute renal failure and toxemia. In case of high amputation, attention should be paid to whether there is acute renal failure and toxemia. 2, local care: ① move the patient slowly and gently, lying position, the affected limb is raised appropriately, slightly above the level of the heart, the reimplanted limb can be placed on the bedside of the special small wooden table, laying aseptic towel, covered with a protective frame. ② the affected limb is properly fixed with a dressing or plaster cast, the bandage should not be too tight, fingers (toes) exposed, covered with sterile towel or gauze, in order to observe blood circulation, pay attention to prevent the casualty from moving the limb after sleeping, so that the blood vessels are compressed and spasm. ③regularly observe the skin color, temperature nail capillary filling and record, arterial blood supply is insufficient when the reimplantation of the end of the limb pale, deflated fingers, skin elasticity disappeared, deepening wrinkles, skin temperature decreased, arterial pulsation weakened or disappeared, nail capillary filling time is prolonged, venous reflux obstruction is manifested as the end of the skin color bruising, swelling, blistering skin, skin temperature decreased, nail Capillary filling time becomes shorter, the bleeding of the end of the needle finger is purple, and the blood circulation obstruction should be reported to the doctor in time. These are some of the ways and means of post-operative care for finger reimplantation, which is not very difficult for the patient or the patient’s family. The main thing is that the patient must have enough confidence in their own recovery, and have patience, so that the recovery will be better.
