Abstract

Background
Superior vena cava collapsibility (SVC C), inferior vena cava distensibility (IVC D) and internal jugular vein distensibility (IJV D) can be used as dynamic parameters for assessment of fluid responsiveness.
Settings and Design
This study aimed to compare between superior vena cava collapsibility, inferior vena cava distensibility and internal jugular vein distensibility as regard their efficacy for fluid responsiveness assessment post cardiac surgery.
Methods
30 patients of American Society of Anaesthesiology (ASA) physical status II or III, of both sexes, aged (18-60) years scheduled for on pump CABG surgery were enrolled in the study.
Results
SVC CI had a 75% sensitivity for detection of fluid responsiveness with 80% positive predictive value. It had a specificity of 78.57% with 73.33% negative predictive value. It had an accuracy of 76.67%. IVC DI has a 68.75% sensitivity for detection of fluid responsiveness with 68.75% positive predictive value. It had a specificity of 64.29% with 64.29% negative predictive value. It had an accuracy of 66.67%. IJV DI had a 56.25% sensitivity for detection of fluid responsiveness with 60% positive predictive value. It had a specificity of 57.14% with 53.33% negative predictive value. It has an accuracy of 56.67%.
Conclusions
SVC CI had more sensitivity, specificity and accuracy in fluid responsiveness prediction followed by IVC DI and IJV DI respectivelys.
