The relationship between central venous pressure and pulmonary capillary wedge pressure was studied in 18 patients with severe pregnancy-induced hypertension. Although statistically a linear relationship for the group as a whole could be identified, analysis on a case-by-case basis revealed different results. In 10 patients, a linear correlation between central venous pressure and pulmonary capillary wedge pressure was observed. However, accurate prediction of pulmonary capillary wedge pressure from central venous pressure was not possible even in this group because of large interindividual variations. In seven patients no correlation between central venous pressure and pulmonary capillary wedge pressure could be identified. In the last patient a curvilinear relationship existed between central venous pressure and pulmonary capillary wedge pressure. Additionally, in five cases of pulmonary edema, a negative gradient of colloid osmotic pressure to pulmonary capillary wedge pressure gradient was observed. Our data suggest that central venous pressure is not a clinically reliable predictor of pulmonary capillary wedge pressure.
对18例重度妊娠高血压综合征患者的中心静脉压与肺毛细血管楔压之间的关系进行了研究。虽然从统计学角度看，整个研究组存在线性关系，但逐例分析得出了不同的结果。10例患者中，观察到中心静脉压与肺毛细血管楔压之间存在线性相关性。然而，即使在该组中，由于个体差异较大，也无法根据中心静脉压准确预测肺毛细血管楔压。7例患者中，未发现中心静脉压与肺毛细血管楔压之间存在相关性。最后1例患者，中心静脉压与肺毛细血管楔压之间存在曲线关系。此外，在5例肺水肿病例中，观察到胶体渗透压与肺毛细血管楔压梯度之间呈负梯度。我们的数据表明，中心静脉压在临床上并非肺毛细血管楔压的可靠预测指标。
