To evaluate the correlation between central venous pressure (CVP) and inferior vena cava (IVC) diameters measured by ultrasonography (Ultrasound) in critically ill patients.
Intubated critically ill patients were enrolled. The CVP values were measured using a U-tube manometer and were compared to the IVC diameters and collapsibility index, which were measured by bedside Ultrasound. Patients younger than 18 years old, who were not intubated, who had an abdominal pressure greater than 12 mmHg, and/or who were admitted for trauma were excluded from the study.
Eighty three patients with a mean age of 73.6±11.2 years were enrolled. The most common diagnosis was sepsis (21 patients, 25.30%). IVC inspiration measurements were statistically significantly correlated with CVP measurements (p0.05, r: 0.1). IVC collapsibility measurements showed a negative correlation with CVP measurements (p<0.01, r: 0.68).
There is a strong correlation between CVP and IVC diameters and the collapsibility index. This is a new formula for evaluating CVP, based on our statistical analyses.
评估危重症患者中心静脉压（CVP）与超声测量的下腔静脉（IVC）直径之间的相关性。
纳入经气管插管的危重症患者。使用U型管压力计测量CVP值，并将其与通过床边超声测量的IVC直径和塌陷指数进行比较。年龄小于18岁、未插管、腹压大于12 mmHg和/或因创伤入院的患者被排除在研究之外。
纳入83例患者，平均年龄73.6±11.2岁。最常见的诊断是脓毒症（21例患者，25.30%）。IVC吸气测量值与CVP测量值在统计学上显著相关（p>0.05，r：0.1）。IVC塌陷测量值与CVP测量值呈负相关（p<0.01，r：0.68）。
CVP与IVC直径及塌陷指数之间存在强相关性。基于我们的统计分析，这是一种评估CVP的新公式。
