Role of inferior vena cava and right ventricular diameter in assessment of volume status: a comparative study

Impact of individual characteristics on sonographic IVC diameter and the IVC diameter/aorta diameter index

“…ACCEPTED MANUSCRIPT 13 Our study also establishes the reference ranges for maximum IVC diameter Our results are generally in agreement with several previous surveys that have found that IVC diameter varies greatly between individuals and is not substantially influenced by individual characteristics [10,11].…”

“…to our knowledge, the data available on the normal sonographic values of IVC are sparse[10,13,14]. A study conducted by Rein et al in 1982 enrolled only 10 healthy subjects and has been cited 19 times since 2006 [10].…”

Flat or fat? Inferior vena cava ratio is a marker for occult shock in trauma patients

“…It has also been shown that in patients with a contracted IVC on ultrasound, a fluid challenge reliably increased IVC diameter and decreased serum lactic acid [11]. Also, clinical evidence of hypovolemia, such as dry mucous membranes, decreased skin elasticity, and cool extremities has been correlated with a contracted IVC on ultrasound [12]. As trauma services are seeing an increase in geriatric trauma patients, the issue of OS becomes more salient.…”

Management of sepsis: from evidence to clinical practice

“…In these conditions the reduced right output leads to caval hypertension. 77,78 The inferior vena cava (IVC) 79,80 is a large bore, extremely compliant, vessel (Appendix Figure 21); its size correlates with the patient's volume status (Appendix Table 6); the vessel contracts and expands with every respiratory cycle and the variations of the size give us a reliable estimation of the right atrial pressure and of PVC.…”
