PurposeTo investigate a new noninvasive method to assess central venous pressure (CVP) in hemodialysis patients, based on the ultrasonographic measurement of the collapsing point of the internal jugular vein (CVPni).
Materials and methodsIn this preliminary, noninterventional, single center study, we enrolled 22 dialyzed patients with an indwelling jugular catheter. CVPni was compared to the gold-standard invasive measurement of CVP using the central venous catheter (CVPi). Agreement between CVPi and CVPni was assessed by Bland and Altman Method. Correlation was assessed by linear regression.
ResultsA strong correlation was observed between CVPi and CVPni (OR=3.47 [2.96; 4.07], P<.0001). For overloaded patients, the area under the curve for the operating characteristic curve was 0.971 (IC95: 0.915; 1.000). For under-loaded patients, area under the curve was 0.971 (IC95: 0.917; 1.000). The mean bias between intra-individual CVPi and CVPni measures was 0.57 cm H2O (SD: 3.1 cm H2O).
ConclusionCVPni appears as a noninvasive and reliable technique. Further studies are required to confirm these results and to assess the direct clinical impact of this new method.
