1519例胎儿心电图的临床价值和相关因素分析

Analysis of 1519 case FECG clinical value and related factors.

目的 对 15 19例胎儿全部实行常规胎儿心电图 (FECG)监测工作 ,探讨胎儿心电图应用情况 ,并对异常FECG结合临床 ,进行临床原因分析。方法 采用随机抽样方法 ,应用杭州产FECG -D型胎儿心电图分析仪进行监测。结果 发现采用横导联方式进行监测检出率为 5 3.5 % ;在孕 2 2w进行监测检出率为 4 5 .8% ;异常FECG检出率为 7.6 4 %。结论 对15 19例FECG的监测发现采用横导联方式并在孕 2 2w～ 2 6w期间进行监测检出率最高、波形效果好。

Objective: We monitored 1519 cases FECG to find out the application of FECG and analysed the clinical factors of abnormal FECG. Methods 1519 cases were randomized and we applied the FECG-D Analysis Meter to monitor. Results: The monitoring rate of precordial leads was higher than other leads; the monitoring rate of more than 22 weeks gestational age was higher than other gestational age; the monitoring rate of head position was higher than other fetal positions; the monitoring rate of abnormal FECG was 7.64%, among that FECGof fetal distress and umbilical cord factor manifested mostly ST-T change, FECG of amniotic fluid opacity and umbilical cord factor manifested mostly fetal tachycardia. Conclusion We found out that the effect of wave form was best and the monitoring rate was the highest under the circumstance of precordial leads and between more than 22 weeks gestational age and 26 weeks gestational age.
