目的探讨分娩期胎儿监护与脐动脉血流速度测定联合应用对围产儿状况的评价。方法应用胎儿监护与脐动脉血流速度测定对225例分娩期孕妇进行观察研究。结果CST混合型和无反应型,脐血流S/D≥3者发生率比反应型者明显增高;第一产程末期与第二产程中,胎心率基线下降至80bpm,胎儿监护图形频法VDEDLD时,脐血流S/D≥3者发生率明显增高。在S/D≥3中,羊水污染程度加重,新生儿1分钟Apgar≤7分及低体重儿明显高于S/D<3组(p<0.005)。结论分娩期应用胎儿监护及脐动脉血流速度测定,可提高胎儿宫内窘迫的诊断率,及时判断出胎儿氧储备能力和健康状况,预防胎儿酸中毒和脑细胞损伤,为临床适时纠正胎儿宫内缺氧,改善胎儿预后状况,降低围产儿病死率,提供了可靠的依据.
Objective To investigate the application of fetal monitoring and umbilical artery blood flow velocity during delivery to assess the status of perinatal children. Methods Fetal monitoring and umbilical artery blood flow velocity were used to investigate 225 pregnant women during labor. Results The incidences of mixed and non-responsive CST and cord blood S / D≥3 were significantly higher than those of reactive type. The rate of fetal heart rate dropped to 80bpm at the end of the first stage of labor and in the second stage of labor, VDEDLD, umbilical cord blood flow S / D ≥ 3 were significantly higher incidence. In S / D≥3, the degree of amniotic fluid contamination was aggravated. Apgar≤7 points and low birth weight one minute in neonates were significantly higher than those in S / D <3 groups (p <0.005). Conclusions Fetal monitoring and umbilical artery blood flow velocity measurement during childbirth can improve the diagnostic rate of fetal distress, determine the fetal oxygen reserve capacity and health status in time, prevent fetal acidosis and brain cell injury, Within hypoxia, improve fetal prognosis, reduce perinatal mortality, provides a reliable basis.
