Summary

Intravascular volume assesment is important for the management of the patients in the intensive care unit. Respiratory variation ratio of the inferior vena cava (IVC) can be determined by ultrasonography (USG) and is a useful tool for hemodynamic evaluation of the patient.

Aim of this study is to search for correlation between respiratory variation ratios of the internal jugular vein (IJV) and the IVC before and after passive leg raise. Another aim of this study is to search for variability between ultrasonographic measurements of different doctors.

Conditions

  • Critically Ill

Interventions

OTHER

USG measurement

IVC was visualized in the subxiphoid long axis by using convex probe (5-1 MHz). Diameters of IVC was measured 2 cm caudally to the junction of hepatic vein in M-mode. IJV diameter was measured in the short axis by using linear probe (12-5 MHz) and M-mode. IJV visualized in the junction of cricothyroid membrane level and midclavicular line. Maximum and minimum diameter values were measured in the M mode. Distensibility (maximum diameter - minimum diameter / minimum diameter) and collapsibility (maximum diameter - minimum diameter / maximum diameter) indices were calculated after USG measurements were done.
