Brief summary

This study aimed to know the consistency of intravascular volume measurement using USG of IVC compared to VPW chest x-ray

Detailed description

Approval from Ethical Committee of Faculty of Medicine Universitas Indonesia was acquired prior conducting the study. Validation and reliability test were done for USG operators by assessing IVC in 20 patients supervised by intensivists. Subjects were given informed consent before participating in the study. Subjects underwent the chest x-ray examination with supine position. The measurement of VPW was done by radiologists, considered normal if the value is 53 ± 5 mm, overload if VPW \> 71 mm. The subjects then underwent the IVC diameter measurement using USG Philips En Visor C, with transthoracal subcostal approach. The result is considered normal if IVC diameter is 1.5 - 2.5 cm and overload if \>2.5 cm, otherwise the subjects is excluded. If the IVC can not be done, subjects will be excluded.

Interventions

DIAGNOSTIC_TESTInferior vena cava (IVC) diameter using USG

IVC diameter is measured from the distal of right hepatic pain and inferior vena cava meeting point using Philips En Visor C USG.

DIAGNOSTIC_TESTVascular pedicle width (VPW)

VPW is measured by drawing a line from the left subclavian artery exit point from aorta perpendicular to the point where superior vena cava crosses with right bronchi.
