ClinicalTrials.gov processed this data on August 23, 2015
Link to the current ClinicalTrials.gov record.

Condition(s) targeted: Hemorrhage; Complicating Delivery, Coagulation Defect

Intervention: 5% Human Albumin " Behring" (Drug); Lactated Ringer (Drug)

Phase: Phase 4

Status: Enrolling by invitation

Sponsored by: Kirsten Cleemann Rasmussen

Official(s) and/or principal investigator(s):
Niels H Secher, MD PHD Prof, Study Chair, Affiliation: Rigshospitalet, University of Copenhagen


In a randomized clinical trial, the purpose is to investigate if perioperative coagulation and hemorrhage is influenced by colloid or crystalloid.

Clinical Details

Official title: Effect of Colloid Versus Crystalloid on Coagulation in Elective Urological Surgery

Study design: Allocation: Randomized, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Outcomes Assessor), Primary Purpose: Treatment

Primary outcome: Measurement of coagulation during surgery and in the recovery room

Secondary outcome:

Measurement of postoperative surgical complications

Measurement of hemorrhage and use of blood products during anesthesia and in the recovery room

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(╬▒) 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.
