妊娠合并脐带绕颈209例胎心监护分析

ANALYSIS OF FETAL HEART RATE IN MONITORING AROUND NECK IN209 PREGNANCIES WITH CORDAROUND NECK

２０９例脐带绕颈病人胎心监护发现：４６例出现自然减速，占２０．００％；７８例胎动时ＦＨＲ加速≥２５ｂｐｍ，占３７．３２％；９１例ＯＣＴ或ＣＳＴ中出现变异减速（ＶＤ）６２例，占６８．１３％。自然减速为胎儿宫内不良征象。有反应型ＮＳＴ出现自然减速应按无反应型ＮＳＴ处理。脐带统颈病人胎心监护出现自然减速、胎动时ＦＨＲ加速≥２５ｂｐｍ，或伴发ＶＤ时，羊水污染、低Ａｐｇａｒ评分的发生率明显增加。

The fetal heart rate monitoring of 209 patients with cord around neckfound: 46 of thd patients (20. 00%) exhibited FHR decelerations during the NST,78 of the patients (37. 32%) had accelerations more than or equal to 25 beat perminute with fetal movement, 91 patients had performed OCT or CST, 62 of the patients (68. 13%) exhibited variable deceleration (VD). FHR deceleration duringthe NST is a potentially ominous sign for fetal well being in uterin. The patientswho had FHR decelerations during reactive NST Should be managed according tononreactive NST. When the Fetal heart rate monitoring of patients with cordaround neck exhibited FHR decelerations during thd NST, FHR accelerations morethan or equal to 25 bpm with fetal movement, or complicated by VD, the incidenceof anmiotic fluid meconium low Apgar scores was markedly increased.
