目的:研究产时胎心监护的可量化指标与新生儿窒息的关系及临床应用价值。方法:选取本院2015年1月至2015年12月收治的255例分娩产妇进行研究。根据新生儿窒息情况分组,其中36例新生儿窒息病例为观察组,219例非窒息病例为对照组。对两组产妇的不同产程阶段进行胎心监护,并做好记录。比较两组孕产妇的分娩情况和围产儿结局、胎儿产时胎心监护量化指标变化。结果:对照组产妇产程中羊水污染比率、合并脐带胎盘因素比率、手术助产率均低于观察组,差异具有统计学意义(P<0.05);对照组单位时间内变异减速与晚期减速个数与观察组比较,差异均无统计学意义(P>0.05);对照组持续减速时间、单位时间内减速幅度低于观察组,差异具有统计学意义(P<0.05)。结论:产时胎心监护的持续减速时间、平均减速幅度这2个可量化指标所占的胎心基线比例可作为辅助解读产时胎心监护依据,对产时新生儿胎心监护的可量化指标进行密切监测,可有效改善新生儿窒息结局。
OBJECTIVE: To study the relationship between quantitative indicators of labor during labor and neonatal asphyxia and its clinical value. Methods: A total of 255 women who gave birth during January 2015 to December 2015 in our hospital were selected for study. According to the neonatal asphyxia group, of which 36 cases of neonatal asphyxia cases were observed group, 219 cases of non-asphyxia cases for the control group. On the two groups of different stages of labor stage of fetal heart rate monitoring, and make a record. The maternal childbirth and perinatal outcome were compared between the two groups, and the changes of quantitative indicators of fetal heart rate monitoring during fetal delivery were compared. Results: The rate of amniotic fluid contamination, the ratio of umbilical cord placenta, and the rate of operation-assisted birth in the control group were all lower than those in the observation group (P <0.05). In the control group, the rate of degeneration and late deceleration Compared with the observation group, the difference was not statistically significant (P> 0.05). The control group sustained deceleration time, deceleration rate per unit time was lower than the observation group, the difference was statistically significant (P <0.05). Conclusions: The baseline of fetal heart rate during the second trimester of fetal heart rate monitoring during delivery can be used as a basis to interpret the labor-time fetal heart rate monitoring. The fetal heart rate monitoring during delivery can be quantified Indicators for close monitoring, can effectively improve neonatal asphyxia outcome.
