胎粪吸入综合征(简称 MAS)是由于胎粪吸入胎儿气管和肺导致机械性梗阻和化学性炎症引起。死亡率大约25％,占整个围产儿死亡的2％。不但羊水过少导致胎粪粘稠,而且脐带受压刺激迷走神经均可能与 MAS 有关。Miyazaki 和 Nevarez已证明产时羊膜腔内输注生理盐水对纠正羊水过少和减轻由于脐带受压引起的可变减速有益。为了努力改善产时伴粘稠胎粪病人的母婴后果,作者1987年元月～1988年4月随机抽取了80例产时伴稠胎粪的足月孕妇(羊水碉、粘、混浊并含明显的颗粒物质认为是“稠胎粪”),其中不包括有绒毛膜羊膜炎体征及任何胎儿窘迫迹象的病人。随机选择44例接受常规处理,36例接受羊膜腔由输液。给接受羊膜腔内输液的病人放入宫腔内压力导管,开始经导
Meconium aspiration syndrome (MAS) is caused by meconium aspiration of fetal trachea and lungs leading to mechanical obstruction and chemical inflammation. The mortality rate is about 25%, accounting for 2% of the total perinatal death. Not only oligohydramnios causes meconium sticky, and umbilical cord compression vagus nerve stimulation may be related to MAS. Miyazaki and Nevarez have demonstrated that intra-amniotic infusions of saline during labor can be beneficial in correcting oligohydramnios and in reducing variable deceleration due to umbilical cord compression. In order to try to improve the maternal and infant outcomes of patients with viscous meconium during delivery, the author randomly selected 80 full-term pregnant women with amniotic fluid during pregnancy (amniotic fluid, sticky, cloudy and containing Obvious particulate matter is considered “meconium”) and does not include patients with signs of chorioamnionitis and any signs of fetal distress. Forty-four patients were randomly selected for routine treatment and 36 received amniotic fluid infusion. To accept the intra-amniotic fluid infusion into the intrauterine pressure catheter, began to guide
