Key result
Noninvasive quantification of central venous pressure by ultrasound showed significant correlation with invasive measurements (preoperative r=0.90; postoperative r=0.93, P<0.01).
Why the study?
Does noninvasive quantification of central venous pressure by ultrasound accurately correlate with invasive measurement in patients requiring intraoperative or postoperative management?
Observational (n=76)
Does noninvasive quantification of central venous pressure by ultrasound accurately correlate with invasive measurement in patients requiring intraoperative or postoperative management?
Effect estimate: r=0.90 (preoperative) and r=0.93 (postoperative)
p-value: p=<0.01
A novel ultrasound-based method for noninvasive central venous pressure measurement demonstrates strong correlation and agreement with invasive catheter measurements.
Ultrasound CVP estimation appears feasible; hypothesis-generating and requires prospective validation before any clinical use.

Xing et al. (2015) conducted an observational in Patients requiring central venous pressure monitoring (n=76). Noninvasive quantification of central venous pressure by ultrasound vs. Invasive central venous pressure measurement was evaluated on Correlation and agreement between noninvasive and invasive CVP measurements (r=0.90 (preoperative) and r=0.93 (postoperative), p=<0.01). Noninvasive quantification of central venous pressure by ultrasound showed significant correlation with invasive measurements (preoperative r=0.90; postoperative r=0.93, P<0.01).
