Chronic utero-placental insufficiency may result in progressive hypoxia culminating in fetal decompensation and acidosis and this is termed 'chronic' or 'long-standing' hypoxia. It is essential to recognise the features of chronic hypoxia on the CTG trace so as to institute timely and appropriate action. The current guidelines may not capture a fetus who starts labour already compromised or limited in its ability to compensate for hypoxic or mechanical stresses during labour. The aim of this short review is to explore the CTG features that allow the clinician to recognise a fetus who may present with an antenatal insult such as chronic hypoxia, anaemia, infection, fetal arrhythmias and preexisting non-hypoxic brain injury.
慢性子宫胎盘功能不全可能导致渐进性缺氧，最终导致胎儿失代偿和酸中毒，这被称为“慢性”或“长期”缺氧。识别CTG（电子胎心监护）描记图上慢性缺氧的特征至关重要，以便及时采取适当措施。当前的指南可能无法涵盖那些在分娩开始时就已经处于受损状态或在分娩期间补偿缺氧或机械性应激能力受限的胎儿。这篇简短综述的目的是探讨CTG特征，使临床医生能够识别可能存在产前损伤的胎儿，如慢性缺氧、贫血、感染、胎儿心律失常和既往存在的非缺氧性脑损伤。
