Beschreibung
Inclusion Criteria:
- end stage renal disease requiring dialysis
- age >18y
- normal cognitive function.
Exclusion Criteria:
- severe left ventricular dysfunction (EF<50%)
- known cardiomyopathy
- symptomatic CAD known valvular disease
- severe anemia (Hgb<7.0)
- patients with prior transplants o
- patients who suffered surgical complications as communicated by the surgical team.
We chose these exclusion criteria to prevent enrolling patients who would not tolerate aggressive hydration possible in the treatment group. The exclusion criteria may be excessively restrictive, however, given the current practice that frequently results in rapid large volume loading without a monitor of intravascular volume status.

Experimental: goal directed fluid therapy
The "treatment" group will initially be given a 1L bolus after induction over 20 minutes (first liter may be Lactated Ringers solution or Plasmalyte, subsequent fluid will be Plasmalyte) followed by maintenance infusion at a rate of 5mL/kg/hr until the graft kidney is removed from ice. After removing the organ from ice, the kidney recipient will be administered supplemental crystalloid until PVI is 10 or lower. Plasmalyte will be warmed in accordance to the departmental hypothermia protocol. A PVI of 12 or lower will be maintained until emergence of anesthesia, at which time the PVI monitor will be removed and all patients will be managed by existing standards (pain control, fluid replacement, hemodynamic goals, etc). a.At the time the treatment group begins receiving goal directed fluid therapy the anesthesia team is to wean any vasopressors aggressively with the goal of terminating infusion as quickly as is safe. |

Aktiver Komparator: Control Group
Control patients will be given a constant infusion of crystalloid (first liter may be Lactated Ringers solution or Plasmalyte, subsequent fluid will be Plasmalyte) at a rate determined by the following: 70mL/kg for the duration of the surgery, 1L bolus after induction (over 20-30 minutes) followed by the remainder as a constant infusion determined by (70mL/kg * wt - 1000mL) / 160 minutes (using the local average of approximately 180 minutes of operative time). a.A Masimo PVI monitor will be placed on the patient on an extremity not affected by an AV fistula and recorded for evaluation, but no fluid administration decisions will be made based on it (providers will not have access to its values). |

Effect of Plethysmography Directed Fluid Administration Tranplanted Kidney
Zeitfenster: 1 year
|
To determine the effect of plethysmography directed fluid administration on the incidence of delayed graft function in kidney transplantation.The treatment group will recieve fluid in a well described short period around the time of anastomosis based on a fingertip adhesive monitor.
By preventing hypovolemia at the time of reperfusion, we expect the transplanted kidney to demonstrate improved function in the near term.

Pleth Variability
Zeitfenster: 1 year
|
Pleth Variability Index (PVI) is a validated non-invasive monitoring method used to assess intravascular volume status, and may prove superior to dosing fluids based on existing parameters (heart rate, blood pressure, anecdotal protocols).
