1992年3月～12月我们对48例产妇采用不同的给药途径注射催产素,观察对第三产程的影响,结果发现脐静脉注射催产素对于缩短第三产程、预防产后出血,较肘静脉注射和肌肉注射作用迅速,收到了良好效果.报道如下.1资料与方法1.1 一般资料 为了便于观察,我们将受试者分为三组:脐静脉注射组(A组)16例;肘静脉注射组(B组)16例;肌肉注射组(C组)16例.其中A组16例中经产者8例,经孕初产妇2例,初孕妇6例;B组16例中经产妇7,经孕初产妇2例,初孕妇7例;C组经产妇5例,经孕初产妇1例,初孕妇10例.1.2 方法 A组:胎儿娩出后立即给予催产素20单位加0.9%氯化钠注射液20ml脐静脉注射.B组:胎儿娩出后立即给予催产素20单位加0.9%氯化钠注射液20ml母体肘静脉注射.C组:胎儿娩出后立即给予催产素20单位加0.9%氯化钠注射液20ml母体肌肉注射.2 结果2.1 第三产程时间即胎儿娩出后到胎盘娩出的时间,见表1对三组有序数据进行秩和检验.P<0.01,有极显著性差异.A组第三产程最短.2.2 胎盘、胎膜娩出的完整性 A组16例胎盘胎膜均能整体剥离并完整娩出,无1例行人工剥离胎盘术;B组16例中有2例行人工剥离胎盘术.这2例均为经孕初产妇;C组16例中有5例行人工剥离胎盘术.其中经产妇1例,经孕初产妇3例,初孕妇1例,并有2例行清宫术,这2例均为经孕初产妇.2.
From March to December 1992, 48 pregnant women were given different routes of administration of oxytocin to observe the effects on the third stage of labor. The results showed that oxytocin injected into the umbilical vein was effective in shortening the third stage of labor, preventing postpartum hemorrhage, Injection and intramuscular injection of rapid effect, received good results .Report as follows.1 Materials and Methods 1.1 General information In order to facilitate the observation, we divided the subjects into three groups: umbilical vein injection group (group A) in 16 cases; elbow vein injection Group B (group B) 16 cases; intramuscular injection group (group C) 16 cases.Among group A group of 16 cases in the production of 8 cases, 2 cases of early pregnancy and 6 cases of early pregnant women; , 2 cases of first trimester pregnancy, 7 cases of first trimester women, 5 cases of pregnant women in group C, 1 case of early pregnant women and 10 cases of early pregnant women.1.2 Method Group A: 20 units of oxytocin plus 0.9% of chlorine Sodium 20ml injection of sodium umbilical vein group B. Group B: immediately after delivery of the fetus given oxytocin 20 units plus 0.9% sodium chloride injection 20ml maternal elbow vein injection.C group: immediately after delivery of the fetus given oxytocin 20 units plus 0.9% Sodium chloride injection 20ml maternal intramuscular injection.2 results 2.1 The third stage of labor that the time of delivery of the fetus to the placenta after delivery, see Table 1 rank order test of the three groups of data.P <0.01, there is a significant difference.A group of the shortest third stage of labor.2.2 placenta, the integrity of the fetal membrane delivery A group of 16 cases of placenta fetal membranes can be completely stripped And complete delivery, no routine manual dissection of placenta accreta; B group of 16 patients in 2 cases of manual dissection placenta accreta .Two cases are pregnant primiparous; C group of 16 cases, 5 cases of manual dissection placenta accreta .Among them, one case of mothers, 3 cases of first trimester pregnancy, 1 case of early pregnant women, and 2 cases of curettage, these two cases are by the first trimester of pregnancy.
