Isolated ductus arteriosus responds by marked constriction to increases in perfusion pressure. If, however, these increases exceed 90 mm Hg-130 mm Hg, the vessel suddenly dilates and its responsiveness becomes depressed. The importance of these findings in postnatal closure of ductus arteriosus is discussed.
孤立的动脉导管对灌注压升高的反应是显著收缩。然而,如果这些升高超过90毫米汞柱至130毫米汞柱,该血管会突然扩张,其反应性会降低。本文讨论了这些发现对出生后动脉导管关闭的重要性。
