Arterial catheters, routinely used in neonatal intensive care units, have been associated with serious complications. In the present studies, retrograde blood flow occurring during routine flushing of peripheral and umbilical catheters is described. This retrograde flow is associated with a significant elevation of blood pressure at distant sites. These phenomena depend on the volume flushed and on the velocity of the flushing process. These phenomena can be prevented by flushing a small volume of 0.5 mL for a period of five seconds.
动脉导管常用于新生儿重症监护病房，但其会引发严重并发症。在本研究中，描述了外周和脐动脉导管常规冲洗过程中出现的逆行血流。这种逆行血流与远处部位血压的显著升高有关。这些现象取决于冲洗量和冲洗过程的速度。通过以5秒的时长冲洗0.5 mL的少量液体，可预防这些现象。
