妊娠晚期胎儿电子监护评价指标的应用与护理

Application and nursing of evaluation indexes of fetal electronic monitoring in late pregnancy

目的 探讨胎儿无应激试验（NST）与脐动脉血流S/D异常值对妊娠晚期胎儿的影响,寻求最佳的护理措施.方法 选择妊娠28周以上NST试验异常105例作为研究组,进行脐动脉血流检测和有效的护理干预措施,回顾性资料98例作为对照组.结果 研究组105例NST异常中,Fischer评分5～7分103例,＜5分2例;脐动脉血流S/D值正常者87例、轻度异常16例、重度异常2例.轻度异常者S/D值为（3.716±0.432）分,吸氧后,S/D值变为（3.132±0.398）分,差异有统计学意义（t=3.977,P＜0.01）.研究组胎儿窘迫、新生儿窒息、低体重儿及围产儿病死率均低于对照组.结论 妊娠晚期有必要常规联合进行NST试验和脐动脉血流检测,及早发现胎儿宫内异常,及时采取有效的监护和护理干预措施,减少新生儿并发症和窒息,降低围产儿病死率.

Objective To investigate the influence of Nan-stress test （NST） and abnormal umbilical blood flow S/D on fetus in late pregnancy, and to explore the effective nursing. Methods A total of 105 cases with abnormal NST, above 25 weeks pregnancy, were selected to be undergone umbilical blood flow graph and effective nursing interventions. Retrospective data of 98 cases were selected as control group. Results According to the results of NST positive eases of the case group, 103 cases with NST Fischer score 5 ～7（98.1% ）, 2cases with less than 4 （ 1.9% ）. Umbilical blood flow S/D of 87 cases were normal （ 82.9% ）, 16 cases were mild abnormity（ 15.2% ）, 2 cases were severe abnormality（ 1.9% ）. Umbihcal blood flow S/D of mild abnormity was （3.716±0.432）, it became lower （3. 132±0.398） after Oxygen was given to the cases. The rates of fetal distress ,neonatal asphyxia, low birth wight neonatal and perinatal mortality in case group were lower than that of the control group. Conclusions NST and umbilical blood flow monitoring should be done as routine tests in late pregnancy in order to detect the fetal abnormal potential reserve, carry into effective monitoring and nursing and reduce neonatal complications , asphyxia and perinatal mortality.
