Impact of Hyperoncotic Albumin to Support Blood Loss Replacement

Bladder cancer occurs mainly in old comorbid patients. The standard treatment of localized muscle invasive bladder cancer is pelvic lymph node dissection and open radical cystectomy with urinary diversion. Optimal perioperative fluid management for this surgery is challenging and still controversial in terms of how much to perfuse, choice of fluids (crystalloids and colloids) to restore hydrated state and volemia.
Fluid treatment is usually performed with either balanced crystalloids fluids or iso-oncotic synthetic colloids, plasma or 5% albumin. Because crystalloids quickly equilibrate between the intravascular and interstitial volumes, they are mainly used to treat dehydration and temporary volume deficits. Iso‐oncotic colloids remain intravascular for a prolonged period. Doubts have been raised about synthetic colloids, and the natural albumin has been used more extensively. Albumin is the main protein responsible for plasma oncotic pressure and its volume expansion effect. An alternative therapeutic option is the mobilization of tissue fluid by infusing a small amount of hyper-oncotic fluid like the 20% albumin solution (endogenous fluid recruitment).
There are still unknown aspects of the physiological effects of hyper-oncotic albumin. One of them is the, in this study investigated, effect of 20% albumin on plasma volume expansion, fluid recruitment, and crystalloid kinetic in the frame of blood loss replacement during cystectomy.
It is expected that fluid replacement with crystalloid will be better sustained intravascularly with the administration of 20% albumin.
