October 17, 2014 updated by: Kirsten Cleemann Rasmussen

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

5% Human Albumin is used for fluid therapy during surgery. This study evaluate whether affected coagulation competence induced by Human Albumin leads to a significant perioperative blood loss when compared to administration of lactated Ringer´s solution.

Data are gathered by the investigators, analysed by the sponsor, and remain confidential throughout the process. The investigators shall be involved in all stages of the study development and vouch for the completeness and accuracy of the data. No third part shall influence the protocol, trial conduct, data analysis, or reporting.

The investigators will include 40 patients undergoing cystectomy. Heart rate, mean arterial pressure, cardiac output are measured after induction of anaesthesia and insertion of the arterial catheter (T0), after establishing normovolaemia but before surgery (T1), after resection of the urinary bladder (T2), at the end of the surgery (T3), and two hours thereafter in the recovery room (T4).

Arterial blood is drawn for whole blood viscoelastic haemostatic assays to record clot initiation (R-Time), formation (Maximal Amplitude, MA), alpha angle(α) and lysis (Ly30) depicting haemostatic competence (thrombelastography). The investigators analyze blood for haemoglobin, creatinine, platelets, and fibrinogen. Furthermore, blood is drawn from the central venous catheter for lactate and blood gas variables (ABL 825, Radiometer, Copenhagen, Denmark). To avoid excessive administration of Human Albumin, patients receive lactated Ringer´s solution if considered needed after the infusion 25 mL/kg of the allocated fluid (non-study fluid).

The fluid balance inclusive the blood loss was calculated after cystectomy, at the end of surgery, and two hours thereafter. The investigators register complications postoperatively inclusive hospital stay until discharge.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Measurement of coagulation during surgery and in the recovery room
Time Frame: up to 1 day after surgery
Changes in fibrinogen, platelets, hemoglobin, alpha angle and maximum amplitude
up to 1 day after surgery

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Measurement of postoperative surgical complications
