摘　　要：目的:探讨胎儿监护胎心基线细变异增加的原因、胎儿宫内储备能力及缺氧情况。方法:选择96例胎儿监护胎心基线细变异增加的图形及96例正常胎心监护图做对照进行临床分析,细变异增加的图形分完全性、间断性,据图形了解其原因并预测胎儿宫内储备能力及缺氧的程度。结果:96例胎心率基线细变异增加的原因与脐带因素有关(如脐带先露、绕颈、身、肢体、过短)。完全性图形占89.7%;间断性图形占63.1%;对照组占11.4%。结论:胎儿监护胎心基线细变异增加的图形与脐带因素有关,而脐带因素是导致胎儿宫内窘迫的主要原因之一,如果出现该图形,未加关注及处理,那么继续发展可致胎儿宫内缺氧。胎心基线细变异增加的图形可以及早了解胎儿宫内储备能力及宫内缺氧程度,及早关注对降低新生儿窒息及死亡率具有重要的临床意义。Objective： To explore the reason of the incrcase of fetal monitoring fetal heart rate baseline thin variability and fetal intrauterine stockpiling ability and lack of oxygen. Methods： The graphs of 96 cases of the increase of fetal monitoring fetal heart rate baseline and the graphs of 96 cases of normal fetal heart monitoring was analyzed. The baseline thin variability graphs had perfectibility and discontinuity. The cause of thin variability increase and predict intrauterine stockpiling ability and extent of the lack of oxygen were fould out by the the graphs. Results. The cause of the thin variability increase in 96 patients was related to the umbilical cord. For example, presentation of cord , cord around neck and body and limbs too short. The perfectibility graph was 89.7% , the discontinuity was 63. 13%. Conclusion： The thin variability increase of fetal monitoring fetal heart rate baseline is related to umbilical cord , while the umbilical cord is one of the main causes of fetal intrauterine distress. If that kind graph appears, hut not well cared for or dealt with, it may cause lack of oxygen in the fetal intrauterine. The graphs of thin variability of fetal heart rate baseline can help to know fetal intrauterine stockpiling ability and the extent of intrauterine lack of oxygen. It has great clinic significance in reducing neonate .asphysia and death rate.
