背景和目标。先前在成人中的研究已经证明了中心静脉压（CVP）和外周静脉压（PVP）之间的临床有用的相关性。本研究前瞻性比较了肾移植受者中心静脉导管与外周静脉导管的中心静脉压测量值。在伦理委员会批准和知情同意的情况下，30名连续的肾脏接受者被纳入研究。我们排除了患有严重瓣膜病或临床上明显的左心室衰竭的患者。对于30名患者，在5个不同的场合测量CVP和PVP。将传感器系统的压力管连接到中心静脉导管的远端腔或外周静脉导管，用于麻醉诱导后、诱导后、诱导后1小时、肾脏再灌注和手术结束后的测量，产生150个血液动力学数据点。每项血流动力学测量包括心率、平均动脉压、平均CVP和平均PVP。术中平均PVP为13.5 ± 1.8 mm Hg，平均CVP为11.0 ± 1.5 mm Hg。平均差异为2.5 ± 0.5（P <0.01）。重复测量方差分析显示PVP和CVP之间存在高度显著的相关性（P <0.01），Pearson相关系数为0.97。在本研究条件下，在无显著心功能不全的患者中，PVP与CVP在围手术期一致性较高。
Background and objective. Previous studies in adults have demonstrated a clinically useful correlation between central venous pressure (CVP) and peripheral venous pressure (PVP). The current study prospectively compared CVP measurements from a central versus a peripheral catheter in kidney recipients during renal transplantation.Methods. With ethics committee approval and informed consent, 30 consecutive kidney recipients were included in the study. We excluded patients who had significant valvular disease or clinically apparent left ventricular failure. For each of 30 patients, CVP and PVP were measured on five different occasions. The pressure tubing of the transducer system was connected to the distal lumen of the central or to the peripheral venous catheter for measurements following induction of anesthesia, after induction, 1 hour after induction, reperfusion of the kidney, and the end of the operation, yielding 150 hemodynamic data points. Each hemodynamic measurement included heart rate, mean arterial pressure, mean CVP, and mean PVP determined at end-expiration.Results. The mean PVP was 13.5 +/- 1.8 mm Hg and the mean CVP was 11.0 +/- 1.5 mm Hg during surgery. The mean difference was 2.5 +/- 0.5 (P < .01). Repeated-measures analysis of variance indicated a highly significant relationship between PVP and CVP (P < .01) with a Pearson correlation coefficient of 0.97.Conclusion. Under the conditions of this study, PVP showed a consistently high agreement with CVP in the perioperative period among patients without significant cardiac dysfunction.
