Обзор

1. Evaluate Inferior Vena Cava Indices (Diameters , IVC-CI)\&carotid doppler measurements (corrected Carotid Flow Time ,Carotid Blood Flow ,Carotid Artery Peak Velocity Variations) as Non-Invasive Technique for volume guided management in AKI Patient. 2. Estimate correlation between IVC (Diameters , IVC-CI) \& carotid doppler measurements (corrected Carotid Flow Time ,Carotid Blood Flow ,Carotid Artery Peak Velocity Variations) as Non-Invasive Technique for volume guided management in AKI Patient.

Подробное описание

Acute kidney injury affects increasing numbers of patients worldwide, it was estimated approximately 15% of all subjects treated in hospitals develop Acute kidney injury,even a small increase in serum creatinine may be associated with increased risk of mortality , Oliguric AKI it imposes a great challenge for fluid management.

Recently, ultrasonography for estimating volume status has been widely recommended because of its non-invasive nature, ease of acquisition, and reproducibility of measurements.Among these ultrasound modalities, ultrasonographic assessment of the inferior vena cava \& Carotid doppler measurements .

In spontaneously breathing patients, the inferior vena cava (IVC) diameter and the IVC Collapsibility Index (IVC-CI) have been shown to correlate with the volume status and central venous pressure (CVP) . also has been shown to indicate fluid status in children , ventilated patients and healthy volunteers .

corrected Carotid Flow Time (CFT) unaffected by respiration predicting fluid responsiveness that has shown promising results.Studies to date have shown that corrected CFT increases in response to fluid administration or consumption , and decreases in response to volume removal in dialysis and blood donation .
