| 中文摘要: |
| 目的 对足月孕妇羊水进行超声回声强度(EI)定量分析,为临床及时诊断胎儿宫内窘迫提供客观的羊水性状指标。方法 对27例足月妊娠孕妇羊水池进行EI定量测定。根据手术分娩后羊水性状分为正常羊水组(16例)及羊水粪染组(11例),比较两组间EI灰阶(GS)、分贝(dB)差异。结果 羊水粪染组灰阶及分贝最大值明显高于正常羊水组。结论 超声组织定征可用于临产前羊水性状的监测。 |

| Objective To find a reliable method to observe the character of amniotic fluid by quantitative analysis of ultrasonic echo intensity (EI) on amniotic fluid in term pregnancy. To provide an Objective index of amniotic fluid character to diagnose fetal distress in time. Methods The EI amniotic fluid in 27 term pregnancy was determined and analysed. After operation, they were divided into two groups according to the character of the amniotic fluid, and compared their difference between gray scale (GS) and decibel (dB). Results The maximum values of GS and dB in meconium-stained amniotic fluid group were higher than those in normal amniotic fluid group. Conclusion Ultrasonic tissue characterization can be used in monitoring the character of amniotic fluid before rupture of membranes and in labor in term pregnancy. |
