BackgroundLow central venous pressure (low-CVP) is the clinical standard for fluid therapy during major liver surgery. Although goal-directed fluid therapy (GDFT) has been associated with reduced morbidity and mortality in major abdominal surgery, concerns remain on blood loss when applying GDFT in liver surgery. This randomized trial compared outcomes of low-CVP and GDFT during major liver resections.MethodsIn this surgeon- and patient-blinded RCT, patients undergoing major open liver resections (≥3 segments) were randomized between low-CVP (n = 20) or GDFT (n = 20). Primary outcome was intraoperative blood loss. Secondary outcomes included the quality of the surgical field (VAS scale 0 (worst)-100 (best)) and major morbidity (≥grade 3 Clavien-Dindo).ResultsDuring surgery, CVP was 3 ± 2 mmHg in the low-CVP group vs. 7 ± 3 mmHg in the GDFT group (P < 0.001). Blood loss (1425 vs. 1275 mL; P = 0.640) and the rate of major morbidity (40% vs. 50%, P = 0.751), did not differ between low-CVP and GDFT, respectively. The quality of the surgical field was comparable between groups (low-CVP 83% vs. GDFT 80%, P = 0.955).ConclusionIn major open liver resections, GDFT was not associated with differences in intraoperative blood loss, major morbidity or quality of the surgical field, compared to low-CVP. Larger RCTs are needed to confirm this finding. Registration number: NTR5821 (www.trialregister.nl).Copyright © 2021 The Authors. Published by Elsevier Ltd.. All rights reserved.
