Hypovolemia During Liver TransplantationNCT01650116
Evaluation of Hemodynamics and Amount of Blood Flowing Through the Kidneys During Liver Transplant by Measuring Some Physiological Substances in Blood and Urines
An observational study of Hypovolemia During Liver Transplantation and Renal Hypoperfusion During Liver Transplantation, run by Azienda Ospedaliera di Padova at 1 site in Italy.
Trial summary
The purpose of this study is to verify any existing relationship between urinary parameters (such as excretion of sodium, chlorine, urinary partial CO2 pressure [PuCO2]) and general volemic indicators (such as PiCCO, ScvO2, O2 delivery) during liver transplant. Read more about this study

About this study
Official title: Evaluation of Sodium Urinary Excretion, Chlorine Urinary Excretion, Urinary Partial CO2 Pressure as Renal Perfusion Indicators During Liver Transplant. Comparison With Other Polemic State Indicators (Such as PiCCO, ScvO2, O2 Delivery).
The purpose of this study is to verify any existing relationship between urinary parameters (such as excretion of sodium, chlorine, urinary partial CO2 pressure [PuCO2]) and general volemic indicators (such as PiCCO, ScvO2, O2 delivery) during liver transplant.
- Conditions
- Hypovolemia During Liver Transplantation, Renal Hypoperfusion During Liver Transplantation
- Keywords
- hypovolemia, renal hypoperfusion, liver transplantation, sodium, chloride, PuCO2, ScvO2, PiCCO, O2-delivery, hemodynamic indexes
- Medical subject headings
- Hypovolemia
What is being measured
The primary outcome is the main question the study is designed to answer.
Determination of hemodynamic indicators (PiCCO, ScvO2, O2-delivery) and three urinary analytes (sodium, chloride, CO2 partial pressure)
Measured: During the stay of the patient in the operating room (in average 8 hours) and the subsequent stay in the post-surgery intensive care unit (in average 5 days)

Where is the study taking place?
The record lists 1 site in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?

What does the primary outcome measure?
Determination of hemodynamic indicators (PiCCO, ScvO2, O2-delivery) and three urinary analytes (sodium, chloride, CO2 partial pressure) (time frame: During the stay of the patient in the operating room (in average 8 hours) and the subsequent stay in the post-surgery intensive care unit (in average 5 days)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Nov 2014.
