Abstract

Deleterious effect of volume overload on the different organs and body tissues raise the need for new devices and techniques for assessment of fluid responsiveness in the perioperative period.
Static methods for fluid management as CVP became not reliable. Dynamic ones are more preferable nowadays due to their accuracy and being more presentable for actual blood volume and its changes during lung and heart cycles including their interactions.
Many studies have been carried out trying for discovering new dynamic maneuvers characterized by being easy, non-invasive, with fewer complications, and in the same time with high sensitivity and specificity.
This study was aiming for comparing the reliability and effectiveness of the PVI and dIVC as easy and non-invasive predictors of perioperative fluid responsiveness by simultaneous recording in all our surgical ICU sedated mechanically ventilated patients.
PLR was used in our study as a harmless reversible technique for fluid challenge, and TTE was used as a gold standard method of identification of fluid responsiveness by an increase in CI≥ 15% post PLR.
The study was conducted on 88 randomly chosen patients in surgical ICU in Ain Shams University hospitals after approval of the medical ethical committee. They were divided according to fluid responsiveness by TTE into responders and non-responders groups.
Demographic data of the two groups were documented. All patients were adequately monitored and assessed by PVI and dIVC then compared with CI obtained by TTE before and after PLR. Patients with 15% increase in CI or more were defined as responders.
The results of the study revealed that there were no significant difference between the two groups regarding demographic data.
The study revealed that PVI and dIVC may be used as non-invasive tools for fluid assessment in ICU with high sensitivity and specificity than CVP, and PVI especially is easier due to its continuous reading, being operator independent and higher reliability than dIVC.
