[Intraoperative anesthetic management of kidney failure in adult liver transplantation. Conventional hemodialysis].
OBJECTIVE
To evaluate our application of indications, use and benefits of conventional hemodialysis during surgery in patients with advanced liver disease and acute or chronic renal failure undergoing liver transplantation (LP), liver retransplantation (LRT) or combined hepatorenal transplantation (CHRT).


METHODS
We retrospectively reviewed the cases of 22 patients with advanced liver disease, 11 with acute renal failure and 11 with chronic renal failure. We performed 6 LT, 5 LRT and 11 CHRT. The following data were recorded in the periods before, during and immediately after surgery: metabolic, hemodynamic and coagulation parameters; bicarbonate, calcium and inotropic drug requirements; incidences during reperfusion of the graft; surgical technique used; and survival.


RESULTS
Seven patients (32%) needed hemodialysis, 4 (18%) needed ultrafiltration, 7 (32%) needed both and 4 (18%) required neither. For 6 patients total clamping of the inferior vena cava (ICV) was required with external venovenous bypass. For 8 patients total clamping of the IVC was performed without venovenous bypass. For 8 others IVC clamping was partial with retrohepatic preservation (piggy-back). There were 2 deaths during surgery, 4 more within the first month after surgery and 4 more in the second month. Overall survival was 36.4% among acute patients and 72.7% among CHRT patients.


CONCLUSIONS
1) Conventional hemodialysis during surgery is feasible and gives good results; 2) conventional "high efficiency" hemodialysis is more effective and useful in these patients than is either slow, continuous hemodialysis or filtration; 3) the survival rate of CHRT patients is similar to that of patients undergoing LT with normal kidney function, and 4) partial IVC clamping in the anhepatic phase may decrease the need for ultrafiltration.
