本文在1896例无负荷试验(NST)监护图型中出现自发胎心率减速图型16例,占NST图型的0.84%,分析表明NST出现自发胎心率减速异常都是胎儿缺氧的信号,表示胎盘储备功能不良,如合并基线变异减少或消失说明胎儿缺氧严重。应结合孕妇及胎儿其他指标进行综合判断,尽快终止妊娠。
In this paper, 1896 cases of no-load test (NST) monitoring pattern appeared spontaneous fetal heart rate deceleration pattern 16 cases, accounting for 0.84% of NST pattern analysis showed that spontaneous fetal heart rate NST deceleration are fetal hypoxia Of the signal, said placental reserve dysfunction, such as reduced baseline merger or disappearance of disappearance of fetal hypoxia.
