摘要
本文目的是综述外周静脉压(PVP)波形的生理学特点、获取方法及临床应用进展.PVP与中心静脉压高度相关和一致,是一种有潜力的替代指标.经上肢浅静脉留置导管,连接压力传感器进行外周静脉波形分析(PIVA),或腕关节掌侧皮肤表面放置专门的压电传感器,进行非侵入性静脉波形分析(NIVA),均可早期识别低血容量状态,包括出血和脱水.对于心力衰竭患者,PIVA/NIVA可准确评估容量过负荷,甚至预测短期恶化风险.PVP主要缺陷是波幅低、信号弱,需要进一步改进以提高临床应用能力.
Abstract
The objective of this paper is to review the physiological characteristics,acquisition methods,and clinical application of peripheral venous pressure(PVP)waveform.PVP is highly correlated and consistent with central venous pressure,which is a potential proxy.Early identification of hypovolemic states,including bleeding and dehydration,can be achieved by placing a catheter through a superficial vein in the upper limb,attaching a pressure sensor for peripheral invasive vein waveform analysis(PIVA),or by placing a specialized piezoelectric sensor on the skin surface of the volar wrist for non-invasive vein waveform analysis(NIVA).In patients with heart failure,PIVA/NIVA can accurately assess volume overload and even predict short-term risk of worsening.The main defects of PVP are low amplitude and weak signal,which need to be further improved to improve the clinical application ability.
