Plain English Summary

Background and study aims
This study will recruit 50 women with metastatic ovarian carcinoma (ovarian cancer that has spread) undergoing a tumour reduction operation. Colloid and crystalloid solutions are given into a patient’s vein (intravenously) during surgery to maintain blood volume. The aim of this study is to find out whether a colloid solution is better than a crystalloid solution for volume replacement (i.e. a lower amount of solution is needed).

Who can participate?
Women aged 18 or over with metastatic ovarian carcinoma undergoing a tumour reduction operation at the University Hospital, Campus Virchow-Klinikum of the Charité - University Medicine Berlin

What does the study involve?
Participants are randomly allocated to receive either a colloid or crystalloid solution intravenously during their surgery. The amount of fluid used is measured, along with other factors such as length of intensive care and hospital stay, complications, pain and quality of life.

What are the possible benefits and risks of participating?
There are no additional treatments or tests for the participants, and the study drugs are common medicines used in everyday hospital routine. The risk to participants is low and there is a low risk of side effects to the study drugs.

Where is the study run from?
Charité - University Medicine Berlin (Germany)

When is the study starting and how long is it expected to run for?
May 2009 to June 2011

Who is funding the study?
Charité - University Medicine Berlin (Germany)

Study information

Scientific title

Balanced crystalloids versus balanced colloids within a goal-directed haemodynamic protocol in patients undergoing gynaecological tumour resection: a prospective, randomised, controlled, double-blinded, two-armed single-centre trial



Study hypothesis

A balanced colloid solution is superior to a balanced crystalloid solution for volume replacement in regard of lower amounts of intra-operatively administered intravenous solutions.

Ethics approval

Gynaecological tumour resection


During gynaecological tumour resection:
1. Intra-operative oesophageal Doppler guided fluid management with a balanced colloid solution
2. Intra-operative oesophageal Doppler guided fluid management with a balanced cristalloid solution

The dosage will be guided by the stroke volume and the corrected flow time of the heart measured by the oesophageal Doppler. The duration of the study protocol identical to the administration of the study medication is from the beginning of the operation up to the end of the operation. Total intravenous Dose per day is 50 ml/kg BW/d for Volulyte and 50 ml/kg BW per day for Jonosteril. Follow up will be 3 months after drug application for all arms.

Phase IV

Drug names

Primary outcome measure

Differences of intra-operatively administered amount of intravenous fluids (balanced colloid versus balanced crystalloid solutions) within a goal-directed haemodynamic management

Secondary outcome measures

1. Doses and duration of therapy with catecholamines measured intra-operatively and post-operatively during intensive care unit (ICU) stay
2. Time and number of hypotensive episodes measured intra-operatively and post-operatively during ICU stay
3. The quantity of intravenous fluid admininstered to the patient during the first 18 hours after surgery
4. The quantity of fluids per day lost by drainage during the first three days after surgery
5. Time that discharge criteria were met (measured by Post-Anaesthetic Discharge Scoring System [PADSS])
6. Length of intensive care stay and length of hospital stay (LOS)
7. The rate of post-operative organ dysfuntions and complications (cardiac, pulmonal, renal, gastrointestinal)
8. The rate of post-operative delirium and the post-operative incidence of post-operative, cognitive dysfunction
9. Weight change until the fifth post-operative day
10. Peri-operative incidence of infections (according to the Centers for Disease Control and Prevention [CDC] and American Thoracic Society [ATS] criteria)
11. Patient, surgeon and anaesthetic satisfaction
12. Pain of the patient
13. Quality of life measured before the operation, at the day of hospital discharge and three months after surgery
14. Laboratory tests: peri-operative endothelial and immunological alterations

The secondary outcome measures were determined if above not specified within the study up to the 10th post-operative day.
