To lessen the risks associated with cannulation of the internal jugular vein, a method to identify the contours of the carotid artery and internal jugular vein at the site of cannulation is proposed. This method uses a doppler flow detector equipped with an adjustable electronic filter which selectively enhances the sound component due either to the arterial or venous flow. This method has been applied clinically and was found to be useful in the identification of the vessels. Since doppler flow detectors are readily available in many hospitals and the required modification is simple, we hope that other institutions will find this technique useful in their clinical practice.
为降低颈内静脉插管相关风险，本文提出一种在插管部位识别颈动脉和颈内静脉轮廓的方法。该方法使用配备可调电子滤波器的多普勒血流探测器，该滤波器可选择性增强动脉或静脉血流产生的声音成分。此方法已应用于临床，发现对血管识别很有用。由于许多医院都很容易获得多普勒血流探测器，且所需修改简单，我们希望其他机构会发现该技术在其临床实践中有用。
