为羊水过少、胎膜早破患者补充羊水量，降低剖宫产率，提高围产儿存活率，采用静脉留置针在Ｂ超监测下经腹穿刺于羊膜腔内，滴注林格氏液。羊水过少组（简称治疗Ⅰ组）３０例，对照Ⅰ组２３例；胎膜早破组（简称治疗Ⅱ组）３６例，对照Ⅱ组 ３０例、羊水过少者当滴注至羊水指数上升≥１０ ｃｍ时，停止滴注；胎膜早破合并早产未临产者，保留针套，间歇滴注至７２ ｈ，结束分娩。胎膜早破已临产者维持滴注直至分娩。结果：两组病例经治疗者剖宫产率明显降低，治疗Ⅰ、Ⅱ组分别为５３．３％（１６／３０），８．３％（３／３０）．与对照Ⅰ、Ⅱ组９１．３％（２１／２３），９０％（２７／３０）比较，有极显著意义（Ｐ＜０． ０１）。产褥病率下降，治疗组与对照组比较，有显著意义（ Ｐ＜０． ０５）、胎膜早破合并早产（２８～３４周）者治疗１１例，无１例围产儿死亡，对照组１０例，围产儿死亡４例，两者比较有显著意义（ Ｐ ＜０． ０５）。提示：采用静脉留置计经腹穿刺羊膜腔内滴注林格氏液治疗羊水过少、胎膜早破效果满意、操作简便安全、无菌性强，值得临床推广。
To oligohydramnios, premature rupture of membranes in patients with amniotic fluid supplement, reduce the rate of cesarean section and improve perinatal survival rate, the use of intravenous catheter needle in the B-ultrasound abdominal puncture in the amniotic cavity, infusion of Ringer’s solution. 30 cases of oligohydramnios (referred to as treatment group Ⅰ), 23 cases of control group Ⅰ; 36 cases of premature rupture of membranes group (referred to as treatment group Ⅱ), 30 cases of control group Ⅱ, oligohydramnios when instillation to amniotic fluid index increased ≥ 10 cm, stop drip; premature rupture of membranes combined with preterm labor without labor, retention needle sets, intermittent infusion to 72 h, the end of childbirth. Premature rupture of membranes have been instilled infusion until the childbirth. Results: The rate of cesarean section in the two groups of patients was significantly lower than that in the two groups (53.3% (16/30) and 8.3% (3/30) respectively). Compared with the control Ⅰ, Ⅱ group 91.3% (21/23), 90% (27/30), a very significant (P <0.01). (P <0.05), premature rupture of membranes combined with premature delivery (28-34 weeks) were treated in 11 cases, no one perinatal death, the control group 10 cases, 4 cases of perinatal death, the two have more significant (P <0. 05). Tip: The intravenous catheter ablation of amniotic fluid in the amniotic fluid injection of Ringer’s too little amniotic fluid, premature rupture of membranes satisfactory results, easy to operate safe, sterile and worthy of clinical promotion.
