胎心监护变异减速与脐带缠颈孕妇体位变化的相关研究

Correlation research on the embryo heart monitoring variable deceleration and the umbilical cord entangle the neck pregnant woman body posture change

目的探讨胎心监护变异减速与脐带缠颈孕妇体位变化的关系。方法把我院孕36w后胎心监护出现变异减速的316例孕妇随机分成两组，左侧卧位胎心监护有变异减速的166例孕妇，采取半卧位或右侧卧位，为观察组；单以左侧卧位进行胎心监护的150例孕妇为对照组。观察两组胎心监护曲线图、脐带缠颈例数、分娩方式及围产儿情况。结果观察组与对照组相比，正常图形较多，轻度变化减速（MVD）、重变异减速（SVD）、脐带缠颈发生率较少，胎儿窘迫、新生儿窒息率减少，差异均有极显著性（P〈0．01）；两组分娩方式无显著差异。结论左侧卧位胎心监护有变异减速的孕妇，改变体位后，胎心监护曲线可恢复正常，脐带压迫解除，甚至使缠绕的脐带松脱，胎儿窘迫、新生儿窒息减少。

Objective To explore the correlation between the embryo heart monitoring variable deceleration （VD） and the umbilical cord entangle the neck pregnant woman body posture changes. Methods 316 cases of 36 w pregnant women with fetus heart rate monitoring （i.e. embryo to supervise） and the VD were randomly divide into two groups, those with left side decubitus embryo heart monitoring still having the VD, 166 patients adopted half decubitus or right flank position as the observation group, other 150 pregnant women who carried on the embryo heart monitoring by only left side decubitus were selected as the control group.Embryo heart monitoring diagram of curves and B ultra sieves were observed in two groups to find out the belt to entangle the neck example number, the childbirth way and encircles produced the situation. Results The observation group and the control group were compared, the normal graph formation rate increased, the mild variable decel- eration （MVD）, the severe variable deceleration （SVD）, the umbilical cord entangles the neck formation rate reduced, the fetal distress, the newborn suffocates rate decreased（P〈 0.01） there was no significant difference in the childbirth way. Conclusion Left side decubitus embryo heart monitoring could make the pregnant women with VD, change their body postures, restore the embryo heart monitoring curve normally, relieve the umbilical cord oppression, even cause the winding umbilical cord to loosen, reduce the fetal distress newborn suffocate rate.
