Optimal fluid resuscitation guided by central venous pressure (CVP) in patients having septic shock with ARDS is a perplexed issue having risk of underfilling and worsening of shock versus fluid overload leading to pulmonary edema. Whether stroke volume variation (SVV) (Flotrac-Vigileo system) guided fluid resuscitation has an impact on improvement of shock, oxygenation and mortality were tested in this single-center prospective study [1, 2].
Inclusion criteria were: (1) septic shock patients with dose of norepinephrine ≥0.1 μg/kg/minute or dopamine ≥10 μg/kg/minute; (2) CVP ≥12 mmHg; (3) PO2/FiO2 ratio ≤200 with ARDSnet protocol ventilation under deep sedation. Exclusion criteria were atrial/ventricular arrhythmias, spontaneous triggering of inspiration, established renal failure needing continuous renal replacement therapy (CRRT). During the 24-hour study period, SVV was continuously monitored with the third-generation Flotrac-Vigileo system (version 3.02). Intravenous fluids were given in the boluses of 250 to 500 cm3 to keep SVV <12% throughout the study period. Vasopressor infusion was titrated to keep MAP >70 mmHg.

SVV guided fluid therapy in septic shock with ARDS may improve shock by optimizing preload in a targeted way without worsening oxygenation.
