Abstract
Background
Central venous pressure measurement has been the standard for patient monitoring during
hepatectomy to assure low pressure and reduce blood loss. Recently SVV has been employed
to monitor preload and guide fluid replacement during liver surgery. The aim of the
study is to determine if SVV correlates with CVP values and may replace CVP measurement.
Methods
From January 2021 to February 2022 thirty patients undergoing 32 liver resections
were included in the study. Repeated paired data of CVP and SVV were determined every
10 minutes throughout liver resection. The Correlation between CVP and SVV values
was calculated. Analysis was then stratified by surgical approach, hilar clamping
tempus, operative timing and PEEP values.
Results
A total number of 519 paired SSV/CVP values were recorded. Only a very weak correlation
between SSV and CVP was detected (Pearson coefficient -0.122/ p=0.005). The results
were unaltered after the stratified analysis by surgical approach, presence of hilar
clamping, operative timing and PEEP use, revealing no correlation between SSV and
CVP values.
Conclusion
The CVP /SVV values do not show a relevant correlation during liver surgery. CVP measurement
is still of value and should not be replaced by SVV monitoring to conduct a safe hepatectomy.
