羊水补充疗法(amnioinfusion)是人工向羊膜腔内注入生理盐水或乳酸林格氏液,操作简单,常用以治疗或预防产时急性胎儿宫内窘迫。其适应症为频发重度胎心变异减速,延长减速、过期妊娠,IUGR、胎膜早破等所致羊水过少,以及羊水混有胎便等。其禁忌症为出现胎心迟发减速及变异减少的明显胎儿宫内窘迫或可疑胎盘早期剥离者。 治疗性羊水补充疗法:产时因脐带血循环受阻所致胎心变异减速最为多见,IUGR和胎膜早破致羊水量减少者(羊水指数≤5cm),易发生胎儿变异减速,但只要基线变异保持正常,不一定意味酸 Amnioinfusion is a kind of manual injection of physiological saline or lactated Ringer’s solution into the amniotic cavity. It is simple and commonly used to treat or prevent acute fetal distress during labor. The indications for frequent severe fetal heart rate variation deceleration, prolonged deceleration, expired pregnancy, IUGR, premature rupture of membranes caused by oligohydramnios, and amniotic fluid mixed with meconium and so on. The contraindications for fetal fetal retardation and mutation of obvious fetal distress or suspicious early placental dissection. Treatment of amniotic fluid supplementation therapy: during labor due to blocked cord blood circulation caused by fetal heart rate variation is the most common deceleration, IUGR and premature rupture of membranes caused by decreased amniotic fluid (amniotic fluid index ≤ 5cm), prone to fetal degeneration, deceleration, but as long as baseline variability Maintain normal, does not necessarily mean acid
