Measurement of Intravascular Volume Using USG of IVC Diameter Compared to VPW Chest X-ray

Study Overview
=================
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.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Inferior vena cava (IVC) diameter<br>subjects underwent IVC diameter measurement after VPW measurement | Diagnostic Test: Inferior vena cava (IVC) diameter using USG<br>* IVC diameter is measured from the distal of right hepatic pain and inferior vena cava meeting point using Philips En Visor C USG.<br>|
| Active Comparator: Vascular pedicle width (VPW)<br>Supine chest x ray was done and the VPW is assessed by radiologists. | Diagnostic Test: Vascular pedicle width (VPW)<br>* 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.<br>|
