    • Background: Central venous pressure (CVP) measurement is a reliable method for evaluating intravascular volume status and cardiac function, however it is an invasive and expensive method that may result in some complications such as arterial puncture, pneumothorax, and development of infections.
    Methods The current study was performed to compare CVP measurements between central and peripheral catheters in infant and children with congenital heart disease during a period of time and to show if the change in CVP and peripheral venous pressure (PVP) is constant. The CVP and PVP in 30 patients were measured simultaneously within 10 consecutive hours.
    Results The mean difference between CVP and PVP was 1.48 ± 0.98 mmHg. The linear regression equation showed that cvp = 0.374 + 0.774 pvp (r = 0.725).
    Conclusion PVP measured from a peripheral intravenous catheter in infants and children with congenital heart disease is an accurate estimation of CVP and its changes has good concordance with CVP over a long time period.
