产程中综合干预对分娩的影响

EFFECTS OF COMPREHENSIVE INTERVENTION IN LABOUR ON PARTURIENTS

1目的 探讨产程中综合干预对分娩的影响。 2方法 选择初产、单胎、足月妊娠、头位 ,进入活跃期未破膜 ,无异常并发症的产妇 2 0 0例随机分为两组。对观察组在不同时相进行一系列干预 ,包括人工破膜、静注地西泮、产妇采取相应体位、徒手扩张宫颈、徒手旋转胎头。 3结果 与对照组比较 ,观察组活跃期及第二产程时间明显缩短 (t=5 .0 4,2 .38,P<0 .0 1,0 .0 5 ) ,活跃期宫口开大和胎头下降速度明显增快 (t=3.13,3.89,P<0 .0 1) ,手术产率和新生儿窒息率明显下降 (χ2 =4.19,4.35 ,P<0 .0 5 )。 4结论 产程中综合干预安全、易行。

Objective\ To study the effects of comprehensive intervention in labour on parturients.\ Methods\ 200 parturients chosen with primiparity, single fetus, term pregnancy, head presentation, unbroken membranes into active phase, and no abnormal complication were randomly divided into two groups (study group: n =100, control group: n =100). For the study group, a series of comprehensive interventions were carried out according to the different periods of labour, including artificial rupture of membranes, injecting diazepam into the veins, parturients adopting corresponding positions, manual dilatation of the cervix and manual rotation of the fetal head.\ Results\ The lengths of the active phase and the second stage in the study group were shorter than those in the control group ( t=5.04,2.38,P <0.01,0.05). During the active phase, the average speeds of the dilatation of cervix and the descent of head presentation were quicker than those in the control group ( t=3.13,3.89,P <0.01). The operative birth rate (1%) and the rate of apnea neonatorum (4%) were lower than those in the control group ( χ 2=4.19,4.35, P <0.05). \ Conclusion\ The measures of corresponding prophylactic intervention on parturients according to the periods of labour are safe, practical and effective.
