Traditional Versus Goal Directed Perioperative Fluid Therapy in High Risk Patients
Traditional Versus Goal Directed Perioperative Fluid Therapy in High Risk Patients. A Randomized, Assessor-blinded Study
Is goal directed fluid therapy reducing postoperative complications in comparison to traditional fluid therapy for gastro surgical ASA III/IV patients?
The investigators compare two groups of patients: one group receives goal directed fluid therapy guided by LiDCOrapid stroke volume variation (SVV), the other gets the "traditional" fluids, ie the current regime.

Standard monitoring.
Initial optimization of fluid status is performed by pulse, BP and anaesthesiologist assessment with Ringer acetate.
Followed by an infusion of 10ml/kg/t Ringer acetate.
Urinary output and blood pressure is used as a surrogate parameter: the infusion rate is increased by a fall in blood pressure or urine output <0.5ml/kg/t.
Bleeding replaced with HES 1:1, otherwise see table for fluid therapy page 9. Vasoactive agents (noradrenaline / phenylephrine) is given if the anesthesiologist considers this necessary.
Postoperative give 1000ml Glucose 5%.
HES or Ringer when low blood pressure, eventually noradrenaline as vasoactive agent.

Standard monitoring. The patient is connected to the LiDCOrapid monitor via an arterial line placed in a.radialis. A bolus of 500 ml Ringer acetate is given before anesthesia. If the stroke volume (SV) increases more than 10%, repeat the procedure until the SV is not increasing. After that, induction of anesthesia. Maintenance fluid is given as Ringer acetate 2ml/kg/t. Continuous monitoring of stroke volume variation (SVV). If SVV> 10%, give a fluid bolus 6ml/kg Ringer acetate. Repeat until SVV <10%. Bleeding is being replaced 1:1 with hydroxyethyl starch. SAG by bleeding >1000ml. By fall in blood pressure and SVV <10%, start vasoactive treatment with epinephrine. Postoperative is given Glucose 5% 80ml/h. |
