胎心率延长性减速24例临床分析

Clinical analysis of FHR prolonged deceleration:a report of 24 cases

目的 :探讨胎心率延长性减速 (PD)的临床意义。方法 :对 2 4例PD进行临床分析 ,取同期胎心监护正常者 3 8例作为对照。结果 :2 4例PD中最常见的相关因素为脐带绕颈和羊水过少。PD组羊水污染率显著高于对照组 ( P <0 .0 5 ) ,但两组新生儿窒息率、剖宫产率无显著差异 ( P >0 .0 5 )。PD合并其它异常图型其羊水重度污染率显著高于单纯PD组 ( P<0 .0 1)。结论 :PD常提示脐带异常或羊水过少 ,PD合并其它异常图型者需尽快结束分娩。

Objective:To explore the clinical significance of FHR prolonged deceleration(PD).Method:24 cases of PD were analyzed and compared to 38 normal individuals.Result:The relative factors were nuchal cord and oligohydramnios in 24 cases of PD.The incidence of MSAF in PD group were statistically higher than those in normal group(P<0.05).but there were no significant differences in the rates of neonatal distress and cesarean section morbidity between PD group and normal group(P>0.05).To cases of PD accompanied with other abnormality patterns,the incidence of severe MSAF were higher than those cases of simple PD(P<0.01).Conclusion:PD indicated cord abnormality or olighydramnios.To cases of PD accompanied with other abnormality patterns,the delivery should be finished in a short period.
