胎心率的变化可以作为胎儿宫内窘迫诊断的一种指标,但也不是唯一可靠的指标。因胎心率改变由多种因素决定,它的变化和出生后Apgar评分并不一定完全符合。临床上仅凭听取胎心率而诊断胎儿宫内窘迫必须慎重。羊水中染有胎粪问题也是作为胎儿宫内窘迫的指标之一,它与Apgar评分关系亦不完全相符,但与胎心变化同时存在则较有意义。当前如何正确诊断胎儿宫内窘迫仍是一个值得商榷的问题,若诊断正确,可避免一部分不必要的剖腹产。
Fetal heart rate changes can be used as an indicator of fetal distress, but not the only reliable indicator. Because changes in fetal heart rate are determined by a variety of factors, its changes do not necessarily coincide with Apgar scores at birth. Only by listening to fetal heart rate and fetal distress in the diagnosis must be careful. Amniotic fluid stained with meconium is also one of the indicators of fetal distress, it does not completely match Apgar score, but with fetal heart rate changes at the same time there is more meaningful. How to correctly diagnose fetal distress at present is still a question worth discussing. If the diagnosis is correct, we can avoid some unnecessary caesarean section.
