Key result
Peripheral venous pressure showed an overall mean bias of 1.83 mmHg compared to central venous pressure, with 95% of measurements within ±2 mmHg, indicating its potential as a substitutional hemodynamic parameter.
Why the study?
Does peripheral venous pressure accurately estimate central venous pressure for volume status monitoring in hypovolemic patients with coronary artery disease?
Observational (n=20)
Yes
Does peripheral venous pressure accurately estimate central venous pressure for volume status monitoring in hypovolemic patients with coronary artery disease?
Mean Difference: 1.83 (95% CI 1.62–2.04)
Peripheral venous pressure shows a clinically acceptable agreement with central venous pressure and may serve as a less invasive substitute for volume status monitoring in hypovolemic patients with coronary artery disease.
May support peripheral venous pressure as a less invasive CVP surrogate in hypovolemic CAD; leaves open confirmation in randomized trials before practice change.
Background: Peripheral venous pressure (PVP) was known to have significant correlation with central venous pressure (CVP) in patients with normal and abnormal cardiac function. The purpose of this study is to evaluate the possibility of PVP as a substitute of CVP for volume status monitoring.

Lee et al. (2004) conducted an observational in Hypovolemia in Coronary Artery Disease (n=20). Peripheral venous pressure (PVP) measurement vs. Central venous pressure (CVP) measurement was evaluated on Mean bias between CVP and PVP (Mean bias 1.83 mmHg, 95% CI 1.62-2.04). Peripheral venous pressure showed an overall mean bias of 1.83 mmHg compared to central venous pressure, with 95% of measurements within ±2 mmHg, indicating its potential as a substitutional hemodynamic parameter.
