Any kind of surgery in the patient after surgery need to have an observation stage, this observation stage is mainly to observe the patient for the operation will not have some kind of postoperative adverse reaction and so on. Finger reimplantation is the same, so how to deal with it after finger reimplantation? 1, systemic observation and treatment of amputation of the patient’s ward should be strictly sterilized isolation, and maintain a certain indoor temperature (22 ± 2 ℃), humidity and proper ventilation. In addition to observing the possible combined injury of craniocerebral, thoracic and abdominal organs, some important complications after amputation and replantation should be fully recognized and dealt with in a timely manner, which mainly include hypovolemia, acute renal failure, fat embolism, low plasma protein, imbalance of water and electrolyte balance, and infections. 2, the observation and treatment of local conditions Once the circulatory crisis of replanted limbs occurs, first of all, we need to quickly determine whether it is an arterial or venous crisis by observing the indicators in Table 15-2, and then further identify whether it is vasospasm or thrombosis. Most circulatory crises that occur suddenly are due to thrombosis. Gradual onset of inadequate blood supply is usually due to vasospasm. Vasospasm can be repeated, are the phenomenon of insufficient arterial blood supply, after blood transfusion, 6-10% low molecular dextrose anhydride, Tolazoline and other anticoagulant, antispasmodic drugs, local insulation or sympathetic ganglion closure and other treatments can be gradually improved. If there is suspected thrombus, should be timely surgical exploration, remove the thrombus or excision of the anastomosis and then suture. 3, re-implantation wound infection Once the infection has been formed, the wound should be incised and drained, and appropriate antibiotics should be used for local wet compresses. Adjust the antibiotics after bacterial culture and drug sensitivity test. Pay attention to systemic supportive therapy, if necessary, can be several times in small quantities of fresh blood plasma. 4, postoperative anticoagulation treatment problems Routine intravenous drip 6% low molecular dextran injection 500~1000ml/day, intramuscular injection of Tolacrine 25mg and poppy base 30mg/6~8h and other drugs. Generally do not need heparin and bicoumarin and other anticoagulant therapy, the key to careful and precise suturing techniques, and a variety of antispasmodic and anticoagulant can only play a secondary role for the combination of thoracic and abdominal and craniocerebral injuries, as well as ulcerative disease, esophageal varices of the patient, potentially fatal bleeding, should be pre-supposed to be full attention. 5, the application of hyperbaric oxygen under normal air pressure human arterial blood oxygen content of 8.53mmol/l, and the physical state of oxygen accounts for only 0.13mmol/l. Hyperbaric oxygen at 3 atmospheric pressure can reach 2.01~2.68mmol/l, 22 times more than the normal pressure. Therefore, hyperbaric oxygen can make the cells get sufficient oxygen supply, the sodium pump resumes operation, the edema gradually subsides, and the microcirculation of the tissue cells is improved. These are some very detailed answers on how to deal with the postoperative treatment of finger reimplantation, these postoperative treatment of finger reimplantation need to do are required to be completed in the hospital, so the key to these postoperative care is the need for patients to fully cooperate with the doctor. And be sure to keep a good mood.
