分娩镇痛初产妇采用自由体位纠正胎方位异常的研究

Study on the use of free position delivery for correcting abnormal fetal positions in primiparous women during labor analgesia

目的探讨自由体位在分娩镇痛初产妇纠正胎方位异常中的应用效果。方法选取分娩镇痛足月初产妇为研究对象,按入院时间分为对照组及干预组。对照组104例行常规仰卧位或半坐卧位分娩,干预组129例采用自由体位分娩。比较两组产妇胎方位异常纠正率、缩宫素使用、分娩方式、第二产程及总产程时间、产后2 h阴道流血量、会阴损伤情况及新生儿Apgar评分。结果干预组胎方位自然纠正率显著高于对照组,两组分娩方式比较,差异有统计学意义(均P<0.05);两组缩宫素使用、会阴损伤、产程时长、产后2 h阴道流血量及新生儿Apgar评分比较,差异无统计学意义(均P>0.05)。结论自由体位分娩能够有效纠正胎方位异常,促进正常分娩,改善不良妊娠结局。

Objective To explore the effect of applying free positioning to primiparous women during labor analgesia for correcting abnormal fetal positions.Methods Full-term in-labor primiparas with abnormal fetal position were selected and divided into 2 groups according to the time of admission.The control group(n=104)was subjected to routine supine positioning or semi-sitting positioning during labor,while the intervention group(n=129)was subjected to free positioning.The rates of fetal position correction and oxytocin use,the mode of delivery,the duration of second stage of labor and all stages of labor,and the vaginal blee-ding volume within 2 h postpartum,the incidence rate of perineal injury,and neonatal Apgar score were compared between the two groups.Results The rate of fetal position natural correction in the intervention group was significantly higher than that in the control group;the mode of delivery had significant difference between the 2 groups(both P<0.05).The rates of oxytocin use and perineal injury,the duration of labor stages,the vaginal bleeding volume within 2 h postpartum,and neonatal Apgar score had no significant differences between the 2 groups(all P>0.05).Conclusion Free position delivery can effectively correct abnormal fetal position,boost a natural birth,and improve adverse pregnancy outcomes.
