Detection of hypovolemia by non-invasive hemodynamic monitoring during major surgery using Ringer´s solution, 5% albumin, or 20% albumin as infusion fluid: a post-hoc analysis of a randomized clinical trial.

ABSTRACT:

Background

Fluid loading with crystalloids is the conventional treatment of major hemorrhage but might tend to create fluid overload. We studied hemodynamic profiles of fluid replacement therapies during major surgical hemorrhage and compared the ability of pulse pressure variation (PPV), plethysmographic variation index (PVI), cardiac output (CO) and Guyton´s approach to detect hypovolemia.

Methods

In this single center randomized controlled trial, fluid replacement therapy to treat hemorrhage in 42 patients was randomized to consist of either 5% albumin (12 mL/kg) or 20% albumin (3 mL/kg) over 30 min, both completed by Ringer lactate replacing blood loss in a 1:1 ratio, or Ringer solution alone in a 3:1 ratio. Measurements included CO, PPV, PVI, arterial and central venous
