CORRELATION BETWEEN CENTRALLY AND PERIPHERALLY TRANSDUCED VENOUS PRESSURE IN PATIENTS UNDERGOING CRANIOTOMY

Abstract

Background: Central venous pressure monitoring is a critical tool in assessing fluid status and cardiac function in patients undergoing major surgeries like craniotomy. However, central venous catheterization carries risks such as infection and thrombosis. Peripheral venous pressure, which can be measured with a simpler and less invasive technique, may offer a viable alternative if it correlates well with CVP.
Objective: To evaluate the correlation between central venous pressure (CVP) and peripheral venous pressure (PVP) in patients undergoing craniotomy and assess the potential of PVP as a less invasive alternative to CVP for hemodynamic monitoring.
Methods: This study included 60 patients undergoing craniotomy at the Department of Anesthesia. CVP and PVP were measured at various time points: immediately post-catheter insertion, 30 minutes post-operatively, 1 hour post-operatively, and 24 hours post-operatively. The correlation between CVP and PVP was analyzed using Pearson’s correlation coefficient and Bland-Altman analysis.
Results: There was a strong positive correlation between CVP and PVP across all time points, with correlation coefficients ranging from 0.84 to 0.88 (p < 0.001). The data suggest that PVP reliably reflects CVP, making it a feasible alternative for venous pressure monitoring in patients undergoing craniotomy.
Conclusion: Peripheral venous pressure correlates well with central venous pressure in patients undergoing craniotomy, offering a less invasive and safer alternative for hemodynamic monitoring. Further research is warranted to validate these findings in broader surgical and clinical contexts.
