Key result
Fluid administration linked to increases in CCA diameter positively correlating with CVP in post-surgical adults.
Why the study?
The study aimed to evaluate the relationship between changes in common carotid artery diameter and central venous pressure in response to a fluid challenge in spontaneously breathing adult patients after major surgeries.
Does the change in common carotid artery diameter correlate with central venous pressure in response to a fluid challenge in spontaneously breathing adult patients after major surgeries?
Observational (n=65)

Effect estimate: r = 0.589
p-value: p=0.001
Changes in common carotid artery diameter correlate with central venous pressure during fluid challenges in surgical ICU patients, but cannot provide a reliable diagnostic cut-off for fluid responsiveness.
No takes yet. Share an insight, caveat, or question.
Carotid diameter changes may track CVP after fluid challenge in post-op patients; leaves open reliable thresholds for responsiveness assessment.
A 2019 study conducted an observational in Intravascular fluid status after major surgeries (n=65). Fluid challenge was evaluated on Correlation between changes in central venous pressure and common carotid artery diameter (r = 0.589, p=0.001). Fluid administration in post-surgical adults yielded a positive correlation between the percentage increase in common carotid artery diameter and central venous pressure (r=0.589, P=0.001).
