Intraoperative fluid optimisation using stroke volume variation in high risk surgical patients
DOI 10.1186/ISRCTN95085011
ClinicalTrials.gov identifier
EudraCT number
Public title Intraoperative fluid optimisation using stroke volume variation in high risk surgical patients
Scientific title Intraoperative fluid optimisation using stroke volume variation in high risk surgical patients: a randomised prospective single-centre study
Acronym SVVOPT
Serial number at source N/A
Study hypothesis Stroke volume variation guided fluid optimisation during major abdominal surgery in comparison with standard haemodynamic management may reduce organ dysfunction development and postoperative morbidity in high risk surgical patients.
Lay summary Not provided at time of registration
Ethics approval Local Research Ethics Committee of University Hospital in Plzen, approved on 14/06/2007
Study design Open randomised controlled trial
Countries of recruitment Czech Republic
Disease/condition/study domain Fluid optimisation of high risk surgical patients undergoing major abdominal surgery
Participants - inclusion criteria High risk surgical patients of both gender scheduled for intraabdominal surgery with presumed blood loss of more than 1,000 ml or longer than 120 minutes with open peritoneal cavity.
Participants - exclusion criteria 1. Patients aged less than 18 years
2. Patients with irregular heart rhythm
3. Those with body weight less than 55 kg or more than 140 kg
Anticipated start date 01/07/2007

Target number of participants 120
Interventions Patients were randomised into protocol or control group using sealed envelopes method.

Fluid management in control group patients was managed using routine cardiovascular and clinical monitoring.

Haemodynamic optimisation of protocol group patients was provided with colloid boluses of 3 ml/kg guided by stroke volume variation and other haemodynamic variables according to the protocol based on data obtained by Vigileo™/FloTrac™ monitor.

After operation fluid management and overall postoperative care was the same in both groups.

Patients were followed at least 30 days after operation, if hospitalised at this day then till hospital discharge.
Primary outcome measure(s) Postoperative morbidity based on occurrence (rate and number) of postoperative infectious and organ complications until 30 days after operation.
Secondary outcome measure(s) 1. Duration of hospital and intensive care unit (ICU) stay
2. All cause mortality
3. Biochemical parameters of oxygen debt during operation and in early postoperative period (8 hours)
