The pressure in the internal jugular vein was measured with the head in three different positions using, first, a short cannula and then a catheter with a round occluded end and two side-holes. These pressures were compared with the central venous pressure. In the horizontal position using the catheter, the two venous pressure measurements were similar. With the open-ended cannula, results could be unreliable with the head turned towards the side of cannulation.
使用短套管,然后使用带有圆形闭塞端和两个侧孔的导管,在头部处于三个不同位置时测量颈内静脉压力。将这些压力与中心静脉压进行比较。在水平位置使用导管时,两次静脉压力测量结果相似。使用开口套管时,若头部转向插管侧,结果可能不可靠。
