分娩期评价胎心率(FHR)主要是依据其基线特征和周期性心动减速,而对FHR的增速强调较少。但人们公认胎心率的加速反应可提示胎儿健康。本文研究100例妇女在分娩活跃期用声振刺激后,胎心率的反应与胎儿后果的关系。在足月分娩活跃期,用电池供能的声振声源固定在孕母腹壁,对准胎儿头部刺激5秒钟,以内监测的胎头电极和外监测宫缩的方法记录胎心率和宫缩,将所记录的FHR图型分成四组:(1)正常型:胎心基线正常,基线变异正常,无明显周期性变化;(2)可疑型:基线呈过速或过缓型,或基线变异减小;(3)警戒型:轻到中度的变 Fetal birth evaluation Fetal heart rate (FHR) is mainly based on its baseline characteristics and periodic cardiac deceleration, while less emphasis on the growth of FHR. However, it is generally acknowledged that the accelerated fetal heart rate response may indicate fetal health. This article studies the relationship between fetal heart rate response and fetal outcomes in 100 women who have been stimulated with acoustic stimulation during the active parturition. During the period of full-term childbirth, the battery-powered sound-vibration sound source was fixed on the abdominal wall of the pregnant mothers and aligned with fetal head stimulation for 5 seconds to monitor fetal heart rate and fetal heart rate Contractions, the recorded FHR patterns were divided into four groups: (1) normal type: normal baseline fetal heart rate, normal baseline variation, no significant periodic changes; (2) suspicious type: baseline was too fast or too slow, Or baseline variation decreases; (3) alert type: light to moderate change
