基于自由体位的分娩方式对产妇自身产程变化及分娩结局的影响分析

目的分析基于自由体位的分娩方式对产妇自身产程变化及分娩结局的影响,为该分娩方式应用于产妇、更好地服务分娩产妇提供理论依据。方法选取2017-2018年于金华浦江第二医院进行分娩的产妇200例随机分为研究组和参照组各100例,参照组采用传统分娩方式,研究组采用基于自由体位的分娩方式。对比两组产妇产程时间、宫口扩张情况、分娩方式、不良妊娠结局发生情况。结果研究组产妇第一、第二、第三产程时间及总产程时间分别为(388.55±102.38)min、(48.69±9.28)min、(6.78±2.45)min、(423.48±116.45)min,低于参照组的(455.29±112.35)min、(66.71±14.10)min、(11.27±3.22)min、(504.27±109.33)min,差异均有统计学意义(P<0.05)。研究组产妇宫口扩张速度(3.14±0.21)cm/h大于参照组产妇的(2.68±0.24)cm/h,宫口全开时间(6.78±1.35)h少于参照组产妇的(8.42±1.24)h,差异均有统计学意义(P<0.05)。两组产妇宫缩间歇时间差异无统计学意义(P>0.05)。研究组产妇自然分娩率61.00%高于参照组的27.00%,剖宫产率13.00%明显低于参照组的39.00%,差异均有统计学意义(P<0.05)。研究组胎儿窘迫、新生儿窒息、产妇下肢麻木/疼痛发生率分别为13.00%、9.00%、2.00%,低于参照组的33.00%、27.00%、10.00%,差异均有统计学意义(P<0.05)。结论基于自由体位的分娩方式可显著缩短产妇的自身产程时间,促进宫口扩张,改善分娩结局,减少不良妊娠结局的发生,临床应用价值较高。

Analysis on the effect of free-body delivery mode on the change of maternal labor process and delivery outcome

Objective To analyze the effect of free-body delivery mode on the change of maternal labor process and delivery outcome,provide a theoretical basis for application of this delivery mode and better service for pregnant women.Methods From 2017 to 2018,200 pregnant women giving birth to their babies in the Second Hospital of Pujiang were selected and randomly divided into study group and control group,100 women in each group.The women in control group were given routine delivery mode,while the women in study group were given free-body delivery mode.The observation indexes included labor time,the dilatation of uterine orifice,delivery mode,and adverse pregnancy outcome.Results The time of the first,the second,and the third stages of labor,and the time of total labor in study group were(388.55±102.38)minutes,(48.69±9.28)minutes,(6.78±2.45)minutes,and(423.48±116.45)minutes,respectively,which were statistically significantly lower than those in control group(455.29±112.35)minutes,(66.71±14.10)minutes,(11.27±3.22)minutes,(504.27±109.33)minutes](P<0.05).The dilatation rate of uterine orifice in study group was(3.14±0.21)cm/h,which was statistically significantly higher than that in control group(2.68±0.24)cm/h],the total opening time of uterine orifice in study group was(6.78±1.35)hours,which was statistically significantly less than that in control group(8.42±1.24)hours](P<0.05).There was no statistically significant difference in the interval time of uterine contraction between the two groups(P>0.05).The rate of spontaneous labor in study group was 61.00%,which was statistically significantly higher than that in control group(27.00%),the rate of cesarean section in study group was 13.00%,which was statistically significantly lower than that in control group(39.00%)(P<0.05).The incidence rates of fetal distress,neonatal asphyxia,lower limb numbness/pain in study group were 13.00%,9.00%,and 2.00%,respectively,which were statistically significantly lower than those in control group(33.00%,27.00%,10.00%)(P<0.05).Conclusion Free-body delivery mode can significantly shorten the length of maternal labor,promote dilatation of uterine orifice,improve delivery outcome,reduce the occurrence of adverse pregnancy outcome,the clinical application value is high.
