Abstract:
PURPOSE: For evaluation of volume status in the emergency department, central venous pressure (CVP) measurement is a standard practice. However, this is an invasive method. Measuring inferior vena cava (IVC) size through ultrasound is promising as a non-invasive method. However, few studies have been reported in Korea. Therefore this study measured IVC size and collapsibility in order to examine the clinical usefulness. METHODS: In a prospective study setting, IVC size was measured with ultrasound for patients whose CVP was measured in the emergency department. IVC size of healthy applicants was measured. RESULTS: The healthy group included 100 people: 68 men and 32 women. The average IVC size of men was 1.8+/-0.4 cm and that of women was 1.8+/-0.3 cm. For collapsibility, men were 0.28+/-0.14 and women were 0.23+/-0.14, thus there was no statistical difference in size and collapsibility between men and women. The patient group included 51 people, average age was 59.9+/-18.5, and 28 (54.9%) were men. This group showed a significant negative correlation between CVP and collapsibility. IVC Max was 1.7+/-0.5 cm, IVC Min was 1.2+/-0.5 cm, median collapsibility was 0.26 (0.15-0.38), mean lactate was 6.4+/-4.4 mmol/L, and median CVP was 10.0 (1.0-14.5) cmH2O. CONCLUSION: IVC collapsibility can be used as a reference measure, or even instead of CVP in certain cases.
