摘要
目的研究产前骨盆三维导航在阴道分娩中的临床应用。方法2016年1月至2017年3月,通过三维灰度和能量多普勒超声检查对子宫颈进行经阴道超声检查,共118名女性符合所有的入选标准,构成了研究对象,年龄为(37.25±4.28)岁;根据国际超声医学协会妇产科学指南,在胎儿头部的跨丘脑平面中经腹部测量头围;使用WS80A Elite超声设备获得耻骨联合的正中矢状图;使用Oblique View Extended Imaging(OVIX)软件在存储的体积上离线测量耻骨弓角度;通过Pearson相关系数分析连续变量之间的线性相关性。结果妊娠年龄(29.37±3.24)岁,身高(163.23±10.87)cm,首次产前检查时BMI(23.23±2.46)kg/m^2,分娩时孕妇BMI(28.37±3.25)kg/m^2,分娩时孕龄(40.03±1.32)周,胎儿出生时体重(3354.26±254.17)g,催产素使用为103例(87.29%);孕妇耻骨弓角度范围66.3°~140.0°,孕妇耻骨角度(109.24°±9.23°),耻骨弓角度范围120°~140°例数为83例(70.34%),较其他范围例数多,差异具有统计学意义(P<0.05);胎儿体积<9.0mm^3中正常54例(90%),早产/出生体重低6例(10%);胎儿体积≥9.0mm^3中正常50例(86.21%),早产/出生体重低8例(13.79%),差异具有统计学意义(P<0.05);孕妇身高(OR:0.94,95%;CI:0.92~0.98,P<0.05)、胎儿头围(OR:1.14,95%;CI:1.08~1.17,P<0.05)和耻骨弓角度(OR:0.90,95%;CI:0.88~0.93,P<0.05)与阴道分娩独立相关,差异具有统计学意义。结论通过产前骨盆三维导航,妊娠36周后胎儿头围和孕妇耻骨弓角度的超声评估可以确定分娩期间风险,对于这些孕妇来说,早期计划分娩可能是有益的。
Objective To study the clinical application of three-dimensional navigation of prenatal pelvis in vaginal delivery.Methods From January 2016 to March 2017,transvaginal ultrasonography was performed on the cervix by 3 D grayscale and power Doppler ultrasonography.A total of 118 women met all the inclusion criteria and constituted our research population,the mean age of 37.25±4.28 years.The head circumference was measured abdominally in the transthalamic plane of the fetal head according to the International Society of Ultrasound Medical Obstetrics and Gynecology;the median sagittal view of the pubic symphysis was obtained using the WS80 A Elite ultrasound device;the pubic arch angle off-line on the stored volume was measured using Oblique View Extended the Imaging(OVIX)software.The linear correlation between continuous variables was analyzed by Pearson correlation coefficients.Results The average age of pregnant women was(29.37±3.24)years old;the average height was(163.23±10.87)cm;the BMI was(23.23±2.46)kg/m^2 during the first antenatal examination and the BMI was(28.37±3.25)kg/m^2 during childbirth;the gestational age was(40.03±1.32)weeks during childbirth.The body weight was(3354.26±254.17)g;the oxytocin was used in 103(87.29%)cases;the average pubic arch angle of pregnant women was 109.24°±9.23°(range 66.3°~140.0°).The number of females with pubic arch angle ranged from 120°to 140°was 83(70.34%),which was more significant than other ranges(P<0.05).There were 54%normal cases(90%)with fetal volume<9.0 mm^3,including 6 cases(10%)of low premature delivery/birth weight,and 50 normal cases(86.21%)with fetus volume≥9.0 mm^3,including 8 cases(13.79%)of low premature birth/birth weight,with statistically significant differences(P<0.05).Height of pregnant women(OR:0.94,95%CI:0.92~0.98,P<0.05),fetal head circumference(OR:1.14,95%CI:1.08~1.17,P<0.05)and pubic arch angle(OR:0.90,95%CI:0.88~0.93,P<0.05)was independently associated with vaginal delivery.Conclusions Ultrasound assessment of the fetal head circu
