Comparison of Conventional Central Venous Pressure with Peripheral Venous Pressure and External Jugular Venous Pressure in Patients with Sepsis

Abstract

therapy in patients with sepsis admitted to ICU. However, insertion of central venous catheter is associated with serious complications. We, therefore measured external jugular venous pressure (EJVP), peripheral venous pressure (PVP) and correlated with central venous pressure (CVP) measured by conventional technique and thus technical difficulty and complications can be avoided. Aims: To evaluate the correlation between conventional CVP with EJVP and PVP values in patients with sepsis. Settings and Design: Prospective observational study. Methods and Material: Study done on 54 patients admitted with sepsis requiring fluid resuscitation. CVP, EJVP and PVP measurements were taken using a water column manometer in cm H2O. All the three venous pressures were repeated 3 times following every fluid challenge of 250 ml. Statistical analysis used: Pearson's correlation and Bland–Altman's analysis. Results: The observations were analyzed by dividing the patients into 2 groups on the basis of CVP measurements Group A (CVP ≤ 10) Mean difference between CVP with PVP and EJVP is >2 cm H2O and p value is insignificant. Group B (CVP >10) Mean difference between CVP with PVP and EJVP is <2 cm H2O and p value (p<0.001) is strongly significant. Conclusions: The present study concludes that, there is definite correlation between CVP, EJVP and PVP in a given patient. Further concludes the difference between CVP and EJVP/PVP was minimum (<2 cm H2O) when the CVP was >10 cm H2O.
