“…It has been suggested that the IVC/Ao index can be used as a useful non‐invasive tool to assess patients' volume status and guide fluid management 39 . In a study by Menon et al, 8 the IVC/Ao index was found to be useful for the analysis of fluid requirements in pregnant women who presented to the emergency department. In a study conducted in Nigeria, the IVC/Ao index was reported to be beneficial in determining the degree of dehydration and the optimal treatment modality in children 9 .…”

“…The size and shape of the IVC are related to central venous pressure and circulating blood volume. The sonographic evaluation of the IVC is the instantaneous demonstration of its volume using a non‐invasive method 7,8 . It has been suggested that the caval aortic index (IVC/Ao index), which is a new parameter for the evaluation of body fluid status, may be useful in demonstrating hypovolemia in newborns, dehydrated children, and pregnant women 8–10 …”

[8][9][10] The intima/media layers in the aortic wall of fetuses with growth restriction and low-birth-weight newborns have been found to be significantly thicker than those of fetuses and neonates with normal growth. 11 These changes that occur in FGR may be an early sign of atherosclerosis, which may lead to complicated outcomes in adult life.…”

ObjectiveTo examine the inferior vena cava (IVC) diameter, aortic diameter, and caval aortic index in fetuses with growth restriction and to compare the findings with fetuses from uncomplicated pregnancies at similar gestational weeks.MethodsThis prospective study was conducted with a total of 176 pregnant women. According to the diagnostic criteria, 84 pregnancies diagnosed with fetal growth restriction (FGR) were compared with a control group of 92 uncomplicated pregnancies at similar gestational weeks.ResultsThe aortic and IVC diameter values were significantly lower in the FGR group (P < 0.001), whereas the caval aortic index was similar between the two groups. The examination of the ultrasound parameters of the cases with FGR according to the neonatal intensive care requirement revealed similar aortic diameter and caval aortic index values but a significantly smaller IVC diameter in the cases requiring neonatal intensive care (P = 0.022).ConclusionWe determined that the aortic and IVC diameter values were smaller in the fetuses with growth restriction, but the caval aortic index was similar in the two groups. The measurement of the IVC diameter in FGR may be useful in predicting the neonatal intensive care requirements of these fetuses.

Background Shock is a potentially fatal condition in neonates that requires timely fluid resuscitation and hemodynamic monitoring. Echocardiography may improve assessment and treatment, but reference values across gestational age (GA) and birth weight (BW) are lacking. This study aimed to correlate key indicators with GA and BW of newborns with nonhemodynamic abnormalities, provide corresponding reference ranges, and evaluate them in neonates with early onset septic (EOS) -shock. Methods A total of 200 control group newborns were enrolled, and the inferior vena cava diameter (IVC), inferior vena cava collapse index (IVC-CI), and inferior vena cava to abdominal aorta ratio (IVC/AO) were recorded using echocardiography. Neonates were grouped based on GA, BW, days of age, and patent ductus arteriosus (PDA). 18 cases of neonatal EOS shock were also monitored using echocardiography. Results IVC and AO significantly increased with GA and BW (P < 0.05). IVC-CI and IVC/AO did not correlate with GA, BW, day of age, and PDA. Compared to control group, the EOS-shock group had significantly decreased IVC and IVC/AO and increased IVC-CI (P < 0.05). Cut-off values for indicating EOS-shock were > 34.15% for IVC-CI, < 47.58% for IVCmin/AO, and < 66.11% for IVCmax/AO. Conclusions IVC-CI, IVCmin/AO, and IVCmax/AO are applicable to all neonates. Although the number of neonates with EOS-shock is limited, the cut-off values still show certain diagnostic value. Further research is needed to determine the universality of the population and the role in the diagnosis and treatment of shock in neonates.
