Introduction: Central Venous Pressure is a valuable parameter in the management of critically ill surgical patients in the ICU. Non-invasive methods to extrapolate the volume status of the patient can aid clinicians in expediting proper treatment. The objective of this study is to find a correlation between Inferior Vena cava (IVC) diameter and collapsibility index (CI) with Central venous pressure (CVP) in critically ill surgical patients. Methods: This cross-sectional study included  60 critically ill patients from  September 2020 – 31st February 2021. We recorded the patient's age, sex, heart rate, blood pressure, CVP, volume status, IVC minimum, and maximum diameter. After taking consent and explaining the procedure to the patient, the maximum IVC anteroposterior diameter was noted at the end of inspiration and end of expiration in centimeters. IVC collapsibility index was calculated using the formula ([IVCdmax-IVCdmin]/IVCdmax*100%). Following this, the CVP of the patient was measured. Results: Among the patients evaluated, 32 were females. The mean age of the participants was 44.90 ± 15.76 years. The mean central venous pressure maintained was 11.10 ± 2.11cm H2O with an inferior vena cava collapsibility index of 29.69 ± 8.75. There was a negative correlation between CVP and IVC collapsibility index (%), which was statistically significant (r = -0.701, n = 60, p < 0.01). A strong positive correlation between CVP and maximum IVC diameter (r = 0.712, n = 60, p < 0.01) and minimum IVC diameter (r = 0.796, n = 60, p < 0.01) was found. Conclusion: Inferior Vena Cava diameter and IVC Collapsibility Index can be used as a reliable substitute to central venous pressure to determine the patient's volume status.

Status Assessment

Fluid therapy is an essential component part management of critically ill patients. Proper estimation of the amount of needed fluids is of great importance due to the well-established adverse effects of marked negative and positive fluids balance. Central venous pressure has been widely used by ICU physicians for volume status assessment. Several methods have been postulated for volume status assessment, among which is the inferior vena cava collapsibility index. As the inferior vena cava is a thin-walled capacitance vessel that adjusts to the body’s volume status by changing its diameter depending on the total body fluid volume. Giving the fact that bed-side ultrasonographic measurement of inferior vena cava diameters is an available, non-invasive, reproducible and quiet easy-to-learn technique, it can provide a safe and quiet reliable replacement of central venous pressure measurement for assessment of volume status assessment. The aim of this study was to find statistical correlation between central venous pressure and caval index, as a step towards validating the above mentioned replacement. 86 critically ill patients from ICU population were enrolled. Simultaneous measurements of central venous pressure and inferior vena cava collapsibility index were observed and recorded on four sessions. Patients were also grouped based on their mode of ventilation and central venous pressure values in order to compare the strength of correlation between various populations. The results showed that Inferior vena cava collapsibility index has significant inverse correlation with CVP value (r= -85, p value ˂0.001 at 95% CI) and it better correlated with mean arterial blood pressure and lactate clearance as compared to central venous pressure. However it correlated better with CVP in spontaneously breathing patients (r= -0.86, p value ˂0.001) than in mechanically ventilated patients (r= -0.84, p value ˂0.001). Inferior vena cava collapsibility index has shown to correlate better with CVP value in lower values (˂ 10 cmH2O) (r= -0.8, p value ˂0.001) than in higher values (≥ 10 cmH2O) (r= -0.6, p value ˂0.001). In addition, an inferior vena caval collapsibility index cut-off value of 29% was shown to discriminate between CVP values ˂10 cmH2O and values ≥10 cmH2O with high Sensitivity (88.6%) and specificity (80.4%). In conclusion, inferior vena cava collapsibility index has a strong inverse relationship with central venous pressure which is more pronounced at low central venous pressure values. Point-of-care ultrasonographically-measured inferior vena cava collapsibility index is very likely to be a good alternative to central venous pressure measurement with a high degree of precision and reproducibility. However, Wide scale studies are needed to validate its use in different patient populations.

Important Study

To the Editor.— I applaud the important study done by Lloyd et al on the "Accuracy of Central Venous Pressure Measurement From the Abdominal Inferior Vena Cava"1 Those of us who help take care of critically ill children know too well the risks and technical difficulties of establishing internal jugular and central venous lines in children. The authors report that the intra-abdominal venous pressure closely reflects that of the intrathoracic venous pressure. They offer the caveat that this may not be accurate in patients with an obstruction to the inferior vena cava by a thrombus or extrinsically by a tumor.
