Diagnostic Accuracy of the Inferior Vena Cava Collapsibility to Predict Fluid Responsiveness in Spontaneously Breathing Patients With Sepsis and Acute Circulatory Failure

Abstract

The collapsibility index of the inferior vena cava during a deep standardized inspiration is a simple, noninvasive bedside predictor of fluid responsiveness in nonintubated patients with sepsis-related acute circulatory failure.

Can point‐of‐care ultrasound predict spinal hypotension during caesarean section? A prospective observational study

“…In women who had ΔVTI (supine‐legs elevated) values between 8% and 21%, the measurement was inconclusive for the prediction of hypotension; however, we could predict hypotension or its absence with a high sensitivity or specificity in 70% of cases. This performance is higher than that of other measurements used in clinical practice, emphasising the potential importance of ultrasound in obstetrics .…”

“…Several ultrasound measurements have been proposed as tools for predicting fluid responsiveness. These include inferior vena cava collapsibility, aortic blood flow peak velocity and even carotid flow . However, none of these has been validated in the pregnant population.…”

Does respiratory variation of inferior vena cava diameter predict fluid responsiveness in spontaneously ventilating children with sepsis

“…Multiple studies in spontaneously ventilating adults have reported the accuracy of respiratory variation in IVC diameter as a predictor of fluid responsiveness, [34][35][36][37][38][39][40] with a pooled AUROC of 0.76. 24 The majority of these studies enrolled mixed patient populations, including those with trauma, dehydration and postoperative surgical patients.…”

Euvolemia—A critical target in the management of acute kidney injury

“…Ultrasound evaluation of the inferior vena cava (IVC) can provide valuable information. If the IVC is dilated (>2.5 cm) and fails to collapse during the respiratory cycle, it is unlikely that the patient will respond to additional fluid; whereas a decline of >25%‐40% in diameter during respiration is highly predictive of fluid responsiveness …”

“…If the IVC is dilated (>2.5 cm) and fails to collapse during the respiratory cycle, it is unlikely that the patient will respond to additional fluid; whereas a decline of >25%-40% in diameter during respiration is highly predictive of fluid responsiveness. 35,36 Improvements in ultrasound technology have led to the use of bedside lung ultrasonography as a way to assess fluid overload. The finding on lung ultrasound of "B-line" artifacts (comet tail like vertical projections from the pleura) indicates fluid within the intra-alveolar septum.…”
