Hand transplantation, a vascularized composite allotransplantation, is a complex procedure involving multidisciplinary collaboration. A 21-year-old man who lost both his forearms was put on the transplant waiting list. Three years later, a 24-year-old brain-dead male donor was selected on basis of blood typing and human leukocyte antigen typing.
Immunosuppression of the recipient was initiated preoperatively with tacrolimus, mycophenolate mofetil, and antithymocyte globulin (ATG) 1 mg/kg infusion over 6 h. Methyl prednisolone 500 mg was give before ATG. Intravenous (IV) meropenem 2 g stat followed by 8 hourly and levofloxacin 500 mg stat followed by once-daily dosing were administered preoperatively for antimicrobial prophylaxis.
Under local anesthesia, right internal jugular vein was cannulated with a 7F triple-lumen catheter. The recipient was induced with propofol and vecuronium for muscle relaxation and morphine as analgesic. He was intubated and maintained in oxygen and nitrous oxide (1:2) mixture with isoflurane (1%), under mechanical ventilation. Supraclavicular brachial plexus block was given bilaterally with 10 mL bupivacaine 0.25% under ultrasonic guidance. Left femoral arterial line and two 16G venous access were secured on the left saphenous and right femoral veins.
Preparation of donor's forearms and dissection of the recipient's forearms were performed simultaneously by two teams of surgeons. The forearm preparation was followed by bony fixation, followed by end-to-end anastomoses of the arteries, veins, and nerves. Methyl prednisolone 500 mg IV was given before reperfusion. Although revascularization was stormy due to continuous ooze from the surgical site, the mean arterial pressure was maintained at 65–85 mmHg by administration of fluids, packed red blood cells (PRBCs), and blood products. The patient developed transient hyperkalemia and metabolic acidosis immediately following reperfusion and was managed with calcium gluconate, glucose insulin bolus, and sodium bicarbonate administration.
The surgery lasted for 14 h, and a total of 11.5 L of crystalloids, 1.5 L of hydroxyl ethyl starch, 8 units of PRBCs, 6 units of fresh frozen plasma, 4 units of pooled platelets, and 300 mL albumin were given. Intraoperatively, adequate urine output of >0.5 ml/kg/h was maintained. The estimated blood loss was around 5200 ml.
Postoperatively, the patient was ventilated for 5 h until fully awake and normothermic. After 2 weeks under intensive unit care, he was shifted to the ward and made an uneventful recovery [Figure 1].
The anesthetic goal in such cases is to maintain optimum blood flow to the allograft and avoidance of vasopressors to prevent vasospasm. Because of hemodynamic instability, necessitating massive transfusion, coagulopathy, and rhabdomyolysis acute kidney injury could happen., Improved oxygenation to donor hands is ensured by hemodilution and controlled hypertension by means of volume expansion. Hemoglobin of around 10 g/dL is usually sufficient.
Postoperatively, the aim is to maintain good graft perfusion and detect the occurrence of immediate complications, acute rejection, or infections. Postoperative regional blocks cause vasodilatation and improve blood flow, in addition to postoperative analgesia. The Pittsburgh Upper Extremity Transplant Anesthesiology Protocol offers guidelines and recommendations for the management of hand transplantation. It mainly focuses on fluid management, intraoperative monitoring of the patient, and regional anesthesia strategies.
