B型超声诊断胎儿脐带绕颈及其临床意义(附155例分析)

B-mode Ultrasonography Uiagnozing Fetal Umbilical Cord Loop on Cervical and Clinical Siginificance (155 Kxamples and Atteclied)

本文对677例28～43周的孕妇作了回顾性分析,诊断脐带绕颈155例,确诊率为95.5%(148/155)。其中头位诊断例数142例,确诊率为98.6%(140/142),臀位诊断例数13例,确诊率为61.5%(8/13)。另外,通过绕颈组与未绕颈组对比观察,脐带绕颈组羊水粪染明显高于未绕颈组(P<0.01)。脐绕颈易致胎儿宫内窘迫,甚至胎死宫内,且绕颈周数越多,皮肤压迹越深,对胎儿危害越大。B型超声诊断胎儿脐带绕颈筒便、直观、无损伤,无痛苦,较之其它诊断技术有其独到之处,可作为产科常规检查项目之一。

The study was a retrospectly analysis on 667 gravidus ranged form 28 to 43 weeks,of whith 155 gravidus were diagnozed as umbilical cord loop on cervical by ultrasonic wave.the correct diag-noses is 95. 5%. In the 155 gravidus, 98. 6% of the cephalic position were diagnozed correctly, 61. 5% of the breech position were diagnozed correctly. Furthemore ,the freqency of amniotic fluid infected by fecal in fetal umbilical cord loop on cervical was higher tban that no loop on cerviacl (P< 0. 01). Um-bilical cprd loop on cervical was declined to detal inter-uterine distress, even dead in uterine. The mumber of circuit was more,the cutaneous imperssions was deeper,the injure on fecus was bigger. In brief, with simple,directness,no damage.no pain,B-ultrasonic wave has the originality on diagnosis to be a obstetrical general check.
