胎儿由于各种原因造成缺氧,均可导致胎儿宫内窒息,缺氧与窒息二者互为因果关系。根据胎儿窘迫的发病原因,目前采用的治疗方法有:一、孕妇左侧卧位胎儿窘迫可发生在孕妇长时间仰卧位时。此时子宫压迫腹主动脉、下腔静脉或盆腔血管,导致低血压综合征而使子宫胎盘灌注量减少。如孕妇立即转为左侧卧位,能立即减少子宫对下腔静脉的压迫而增加子宫胎盘血流,这是最简单而有效的治疗方法。有时如脐带受压,改为侧卧位也可松动脐带, Fetal hypoxia caused by a variety of reasons, can lead to fetal asphyxia, hypoxia and asphyxia both cause and effect relationship. According to the causes of fetal distress, the current treatment methods are: First, the left fetal position of fetal distress can occur when the pregnant woman supine for a long time. At this point the uterus pressure abdominal aorta, inferior vena cava or pelvic vessels, leading to hypotension syndrome and uterine placental perfusion decreased. Such as pregnant women immediately into the left lateral position, can immediately reduce the uterine pressure on the inferior vena cava and increase uterine placental blood flow, which is the most simple and effective treatment. Sometimes, such as umbilical cord compression, to the lateral position can also loose the umbilical cord,
