Intervention / Behandling
Detaljeret beskrivelse
Patients will be given 5-7 ml/kg of crystalloid (lactated Ringer's) in the immediate preoperative period, which will be followed by 4 ml/kg/h crystalloid for maintenance normalized to ideal body weight [Men: Ideal Body Weight (in kilograms) = 52 kg + 1.9 kg for every 2.5 cm over 150 cm; Women: Ideal Body Weight (in kilograms) = 49 kg + 1.7 kg for every 2.5 cm over 150 cm].
They will then be randomly assigned to additional volume replacement, guided by esophageal Doppler, to either lactated Ringer's solution of Voluven starch.

Intervention / Behandling |
|---|---|
|
Aktiv komparator: Crystalloid
Lactated Ringers solution will be used for fluid replacement.
|
For goal directed volume management we use corrected aortic flow time (FTc) and stroke volume derived from esophageal Doppler as in previous studies.
In case of hypovolemia, detected by esophageal Doppler monitoring (CardioQ, Deltex Medical Group PLC, Chichester, UK) according to a previously published algorithm, an additional fluid bolus of 250 ml of LR will be given over a period of 5 minutes.

Aktiv komparator: Colloid
Low-molecular weight colloid HES 130/0.4
(Voluven) will be used for fluid replacement

In case of hypovolemia, detected by esophageal Doppler monitoring (CardioQ, Deltex Medical Group PLC, Chichester, UK) according to a previously published algorithm, an additional fluid bolus of 250 ml of Hydroxyethylstarch 6% 130/0.4
(Voluven®Fresenius-Kabi, Bad Homburg, Germany) will be given over a period of 5 minutes.
