Abstract:
Objective: To determine the correlation between central
venous pressure (CVP) measured by conventional central
venous access and ultrasonographic measurement of
internal jugular vein (IJV) height and inferior vena cava (IVC)
diameter. Methods: A prospective, cross-sectional,
convenience sampling observational study. Results: 25
patients from the Emergency Department (ED) Universiti
Kebangsaan Malaysia Medical Centre (UKMMC) were
studied between 1st March and 30th April 2013. The median
age was 63 years (95% CI 54-67). There was a significant
correlation between IJV height and CVP using central
venous access (r=0.64 p<0.001). Correlation between IVC
diameter in end expiration and CVP was 0.74 (p<0.001). An
IJV height measurement >8cm predicted a CVP >8cm H2O
(sensitivity 71.4%, specificity of 83.3%). Conclusion:
Measurement of IJV height and IVC diameter by
ultrasonography correlates well with invasive CVP and is
useful for the assessment of volume status in critically ill
patients in the ED.
