目的探讨超声提示胎儿脐带绕颈孕妇临产后连续胎心监护对围生儿预后的影响。方法对2004年12月至2005年4月辽宁盘锦市第四人民医院产前诊断脐带绕颈的132例孕妇,入产房后,常规采用外监测法进行连续性产时胎心监护。结果132例超声提示脐带绕颈孕妇中发现重度变异减速及频发晚期减速不祥图形30例(占22.7%),发生在潜伏期者6例(占20%),活跃期21例(占70%),第2产程3例(10%),均及时改行急诊剖宫产。无重度新生儿窒息,轻度新生儿窒息3例,全部复苏成功,无围生儿死亡。结论对产前超声提示脐带绕颈孕妇进行全产程胎心监护,有助于及时发现胎儿窘迫并及早处理,可有效避免新生儿重度窒息和围生儿死亡。
Objective To investigate the effect of ultrasound on the prognosis of perinatal infants after continuous labor of fetal heart rate monitoring. Methods From December 2004 to April 2005, a total of 132 prenatal diagnosis of umbilical cord around the neck of the Fourth People ’s Hospital of Panjin City, Liaoning Province were enrolled in the delivery room. The fetal heart rate was routinely monitored by external monitoring method. Results In the 132 cases of umbilical cord around the neck, there were 30 cases (22.7%) with abnormal mutation and severe ominous pattern of delayed decelerations, 6 cases (20%) with latent period and 21 cases (70%) with active stage. , The second stage of labor in 3 cases (10%), promptly switched to emergency cesarean section. No severe neonatal asphyxia, mild neonatal asphyxia in 3 cases, all successful recovery, no perinatal death. Conclusion Prenatal ultrasound suggests that the umbilical cord around the neck pregnant women during full-term fetal heart rate monitoring, help to detect fetal distress and early treatment, can effectively prevent neonatal severe asphyxia and perinatal death.
