Randomized Trial of Intraoperative Intravascular Effect of Hyper-oncotic 20% Albumin, Iso-oncotic 5% Albumin and Ringer Lactate During Haemorrhage in Cystectomy. A Prospective Randomized Active-controlled Single Centre Trial
In Brief
A Phase 4 clinical trial evaluating Hyperoncotic Albumin 20%, Isooncotic Albumin 5%, and 1 other intervention for Blood Loss, Surgical and Fluid Retention. Completed, enrolled 42 participants across 1 site.
Detailed Summary
Fluid intravascular replacement is usually performed with either balanced crystalloids or iso-oncotic colloids, (synthetic colloids, plasma and 5% albumin). Doubts have been raised about synthetic colloids, and albumin solutions have been used more extensively. Albumin is the main protein responsible for plasma oncotic pressure and its volume expansion effect. The mobilization of extravascular fluid by infusing a hyper-oncotic solution like 20% albumin solution has been shown, causing endogenous fluid recruitment and blood volume expansion. The primary objective of this study is to compare the effect on plasma volume expansion and fluid recruitment of 3 different types of fluids (Albumin 5% and Albumin 20% and Ringer-lactate) during the hemorrhagic phase of the cystectomy procedure. Secondary objectives are the assessment of the hemodynamic parameters during surgery and the follow-up of pro-ANP and pro-BNP peptides. Glycocalyx proteins will be followed to evaluate endothelial wall shedding and microcirculation damages.

Interventions
Intravenous administration during removal of the bladder (i.e. the bleeding part) of cystectomy procedures.
Intravenous administration of Albumin 5% 12ml/kg (ideal body weight) completed by a Ringer-lactate crystalloid ratio 1:1 to total amount of blood loss during removal of the bladder (i.e. the bleeding part) of cystectomy procedures.
Intravenous administration of Ringer-lactate ratio 3:1 of total of blood loss during removal of the bladder (i.e. the bleeding part) of cystectomy procedures.
