分娩期内窒息是足月婴儿神经发病的一个重要原因并由于乏氧和低灌注可促成一系列生化反应。遗憾的是对窒息没有一致的临床定义,而且已经设计出几种方法说明这种情况并预测以后的结局。胎儿可很好适应艰苦的分娩。在阴道分娩过程中,胎儿有某种程度的窒息几乎是不可避免的,但得到了各种生理保护机制的对抗。最初的适应涉及有利于大脑、心肌和肾上腺的心输出量的重新分布。在乏氧期,随着乳酸的产生和细胞内ATP的消耗而出现无氧糖酵解。这种状态是完全可逆的,而无需处理。但当代产科的处理是针对有心率改变或酸中毒这种“受 Asphyxia during labor is an important cause of full-term infantile neuropathy and can contribute to a series of biochemical reactions due to hypoxia and hypoperfusion. Unfortunately there is no consistent clinical definition of asphyxia, and several methods have been devised to account for this situation and predict future outcomes. The fetus can be well adapted to difficult labor. In the process of vaginal delivery, the fetus has some degree of asphyxia almost inevitable, but has been a variety of physical protection mechanisms confrontation. Initial adaptation involves redistribution of cardiac output that favors the brain, myocardium and adrenal glands. During hypoxia, anaerobic glycolysis occurs with the production of lactic acid and the depletion of intracellular ATP. This state is completely reversible without any treatment. However, the treatment of contemporary obstetrics is aimed at heart rate changes or acidosis this "by
