Traditional Versus Goal Directed Perioperative Fluid Therapy in High Risk Patients
|ClinicalTrials.gov Identifier: NCT01473446|
Recruitment Status : Terminated (High exclusion rate)

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.

No Intervention: Control
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.
|Experimental: Goal directed fluid therapy||
Procedure: Goal directed fluid therapy guided by LiDCOrapid
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.
- Postoperative complications [ Time Frame: 5 days after surgery ]
- Length of hospital stay [ Time Frame: 3 month after surgery ]
- Complications until discharge and readmission within 30 days [ Time Frame: 3 month after surgery ]
- Mortality within 30 days and 3-month after surgery [ Time Frame: 3 month after surgery ]
- Renal function [ Time Frame: 5 days after surgery ]defined by RIFLE criteria
- Vasoactive agents need [ Time Frame: 3 month after surgery ]Difference in the number of patients in need of vasoactive agents, during surgery and in the postoperative period.
