摘　　要：目的探析分娩前1周孕妇充盈膀胱对超声诊断评估结果的影响。方法270例正常分娩的胎儿,均在孕妇分娩前1周膀胱充盈(A组)和膀胱未充盈(B组)时及胎儿娩出时(C组)行超声检查,测量胎儿股骨长(FL)、腹围(AC)、胎儿双顶径(BPD)、头围(HC)等,并对胎儿体质量进行估算。对比三组的生长发育参数、标准切面获取率、超声绝对误差值,并分析孕妇超声诊断结果。结果A组的体质量、HC、BPD均高于B组,差异有统计学意义(P<0.05);A组与B组的AC、FL对比,差异无统计学意义(P>0.05);A组的体质量低于C组,差异有统计学意义(P<0.05),但两组HC对比差异无统计学意义(P>0.05);B组的体质量、HC均低于C组,差异有统计学意义(P<0.05)。A组HC、BPD标准切面的获取率为91.85%,高于B组的65.19%,差异有统计学意义(P<0.05);A组绝对误差值占出生体重<10%比例100.00%高于B组的75.56%,绝对误差值占出生体重<5%比例87.41%高于B组的70.00%,超声预估胎儿体质量(EFW)-出生体质量(BW)平均绝对误差(78.8±64.3)g低于B组的(141.2±92.6)g,差异有统计学意义(P<0.05)。270例孕妇的膀胱最大容量(325.7±22.9)ml、最小容量(78.5±7.7)ml、平均容量(161.4±13.0)ml。膀胱充盈后发现19例胎盘位置存在异常,其中12例低置胎盘,7例边缘性前置胎盘;2例帆状脐带入口伴血管前置,其中中央型1例。结论在孕妇分娩前1周膀胱充盈状态下实施超声检查,EFW与实际体重更为接近,可清晰显像母体宫颈、胎儿附属物等。Objective To discuss and analyze the effect of bladder filling 1 week before delivery on ultrasound diagnosis results.Methods The 270 pregnant women who gave birth normally underwent ultrasound examination when the bladder was filled(group A)and not filled(group B)within 1 week before delivery,and during delivery(group C).The fetal femoral length(FL),abdominal circumference(AC),biparietal diameter(BPD)and head circumference(HC)were measured,and the fetal body mass was estimated.The growth and development parameters,acquisition rate of standard section and absolute error of ultrasound were compared among the three groups,and the ultrasound diagnosis results were analyzed.Results The body mass,HC and BPD of group A were higher than those of group B,and the difference was statistically significant(P<0.05).There was no statistically significant difference in AC and FL between group A and group B(P>0.05).The body mass of group A was lower than that of group C,and the difference was statistically significant(P<0.05),but there was no statistically significant difference in HC between the two groups(P>0.05).The body mass and HC of group B was lower than that of group C,and the difference was statistically significant(P<0.05).The acquisition rate of HC and BPD standard section of group A was 91.85%,which was higher than 65.19%of group B,and the difference was statistically significant(P<0.05).The proportion of absolute error value to birth weight<10%100.00%of group A was higher than 75.56%of group B,proportion of absolute error value to birth weight<5%87.41%was higher than 70.00%of group B,and ultrasonic estimated fetal weight-body weight(EFW-BW)mean absolute error(78.8±64.3)g was lower than(141.2±92.6)g of group B.The difference was statistically significant(P<0.05).The largest bladder capacity,smallest bladder capacity and average bladder capacity of 270 pregnant women were(325.7±22.9),(78.5±7.7)and(161.4±13.0)ml.After the bladder filling,19 cases of abnormal placenta position were found,including 12 cases of low p
