Aim: Determination the correlation between inferior vena cava collapsibility index (IVCCI), passive leg rising test (PLRT), central venous pressure (CVP), and lactate and veno-arterial carbon dioxide difference (ΔpCO2) parameters that are used for evaluating hypovolemia in critical patients in intensive care units and determining the disposability of ΔpCO2 for this reason.
Materials and Methods: When patients were supine-neutral position, CVP was measured. CVP values less than 8 mmHg (CVP <8 mmHg) were evaluated as hypovolemia. When the patients were at the same position, with the echocardiography (ECHO) probe of ultrasonography device, inferior vena cava (IVC) was monitored and IVCCI values were calculated. IVCCI values larger than 45% (IVCCI >45%) were evaluated as hypovolemia. The patients were applied blood pressure-controlled passive leg lifting test (PLLT), and >12% increase at systolic blood pressure was accepted as positive. After that, simultaneous central venous and arterial blood gas of patients were studied, and ΔpCO2 and arterial lactate levels were controlled.
Results: As a result of our study, we have detected a medium level negative correlation (p=0.02) between IVCCI and CVP, and medium level positive correlation between IVCCI and PLLT. However, weak positive correlation (p=0.032) has been detected between IVCCI and lactate level. Any correlation detected between ΔpCO2 and other parameters.
Conclusion: IVCCI can be used for volume evaluation of intravascular fluid since it is a noninvasive method and at the same time, it is statistically in correlation with CVP, PLLT and lactate.
