“…and CVP. In 2017, Vaish et al [22] carried out a study on 50 patients staying in pediatric intensive care unit and stated that there is a positive correlation between VCI diameter and CVP, and a negative correlation between VCI diameter and VCI-CI. Besides, they indicated in this study that effective volume treatment increases VCI diameter and decreases VCI-CI.…”

Background: Accurate and rapid assessment of intravascular volume status of the patients in emergency services and intensive care units at diagnosis, treatment and follow-up stages is crucial yet rather difficult. The purpose of hemodynamic monitoring is to determine cardiovascular insufficiency and to provide the most suitable treatment for unstable patients in critical condition. Aim: The study aims to compare vena cava inferior diameter, vena cava inferior- collapsibility index (for spontaneously breathing patients) and vena cava inferior- distensibility index (for patients breathing on mechanical ventilation support) measurement by ultrasonography to central venous pressure measurement by placing invasive catheter for assessment of the intravascular volume status and making an accurate volume replacement in emergency service and intensive care units and to determine the correlation between them. Material and Methods: The study was carried out prospectively on the patients above the age of 18 who applied to the emergency service clinic between the dates of 01.06.2014 and 01.04.2015 or who stayed in the emergency intensive care unit between these dates. Measurements were taken from vena cava inferior in both the inspirium and expirium phases by using M mode and they were recorded in millimeter. Simultaneous central venous pressure measurements were performed on the patients by using manometric devices and the results were recorded in cm H2O. Results: 43.3% of the patients were female (n: 26) and 56.7% were male (n: 34), and the mean age is 70.58 ± 14.86. The study found high degree of positive correlation between central venous pressure and vena cava inferior diameters and high degree of negative correlation between vena cava inferior- collapsibility index . The study also found that there is a high degree of negative correlation between vena cava inferior- distensibility index and central venous pressure in patients receiving mechanical ventilatory support. Conclusion: Measurement of respiratory variation in vena cava inferior diameter by using ultrasonography is a quick, reliable, easily applicable, cost-efficient and non-invasive method in critical patients receiving mechanical ventilatory support or have spontaneous respiration in emergency services and intensive care units and it can be useful in assessing the volume status and estimating central venous pressure.

Background Operations performed with the patient in the prone position can pose a significant challenge to the anesthesiologist. Hypotension is a commonly encountered complication. Intravascular volume depletion and decreased cardiac output secondary to decreased preload are thought to be the most likely cause of hypotension in the prone position. Measurement of inferior vena cava (IVC) diameter via point-of-care ultrasound examination (POC_US) has been used to provide an estimate of intravascular volume status. However, this measurement is most often obtained with the patient in the supine position. Materials and methods In this study, we describe a technique for evaluating IVC diameter via POC_US in the prone position. Right lateral long axis imaging of the IVC was used to assess the intravascular volume status of 10 patients undergoing lumbar spine surgery in the prone position. In addition, we used a non-invasive measure of cardiac output to correlate changes in IVC width with changes in cardiac output. Results Images of the IVC in the prone position were obtainable in all 10 patients. IVC diameter increased in six out of 10 patients on going from supine to prone position. The increase in IVC diameter corresponded to an increase in cardiac output, measured noninvasively in five out of the six patients. Conclusions Our findings indicate that POC_US examination of the IVC is possible in the prone position. Further study of a larger patient population could demonstrate the utility of this technique in assessing intravascular volume status in patients undergoing surgery in the prone position.

“…Correct fluid therapy is essential in decreasing the risk of mortality and morbidity related to multiple organ failure 26 and CCE can provide information on volume status and fluid responsiveness. 27 There are two methods to assess volume status and fluid responsiveness with CCE. The first is to examine inferior vena cava (IVC) diameter.…”

CCE can be used to guide pericardiocentesis.…”

Recently, the use of point-of-care ultrasonography (POCUS) by pediatricians especially in emergency and intensive care departments has become increasingly popular. Critical care echocardiography (CCE) quickly and accurately identifies cardiac function, allowing intensivists to manage critically ill pediatric patients by manipulating vasoactive-inotrope-fluid treatment based on the echocardiographic results. Training courses for POCUS are increasingly available and more intensivists are learning how to use CCE. In this review, we focus on the importance and utility of CCE in pediatric intensive units and how it assists in the management of hemodynamically unstable pediatric patients. We highlight the common measurements carried out by intensive care specialists and emphasize the role of the CCE methods in PICUs.

The Correlation Between Inferior Vena Cava Diameter Measured by Ultrasonography and Central Venous Pressure

Abstract: Effective fluid resuscitation improves IVC diameters with a decrease in CI. IVC diameter has a positive correlation to CVP and CI has a negative correlation to CVP.
