摘　　要：目的探讨孕36周后孕妇膀胱充盈后超声估测胎儿体质量(EFW)的临床应用价值。方法随机抽取2010年10月—2011年6月在我院分娩的正常头位胎儿106例;孕妇均在分娩前7 d内进行产前超声检查,孕周均≥36周。孕妇膀胱充盈(A组)和膀胱未充盈(B组)时均进行经腹部胎儿二维产前超声检查,并追踪其出生时(C组)体质量及头围。结果 (1)A、B组胎儿双顶径和头围的标准切面获取率分别为88.7%(94/106)、67.9%(72/106),二者比较差异有统计学意义(P<0.05)。(2)A、B和C组胎儿头围分别为(338.2±17.9)、(332.7±14.6)、(342.0±18.5)mm,胎儿体质量分别为(3 448±305)、(3 307±311)、(3 430±286)g,其中A组胎儿头围及体质量与C组比较差异无统计学意义(P>0.05);而A组与B组比较,B组与C组比较,差异均有统计学意义(P<0.05)。(3)A、B组胎儿双顶径分别为(93.1±10.5)、(90.8±6.9)mm,两组比较差异有统计学意义(P<0.05)。结论孕36周后产前超声诊断时孕妇充盈膀胱有利于胎儿双顶径、头围的标准切面获取,且胎儿头围及体质量的测量值更接近于出生后实际头围及体质量。Objective To explore the clinic value of ultrasonic estimating fetal weight after 36 gestational weeks through filling the bladder of pregnant women.Methods 106 late pregnant women with right position fetus in our hospital from October 2010 to June 2011 were randomly selected.All the pregnant women were examined by prenatal ultrasound less than 7 days before delivery and their gestational weeks were all over 36 weeks.Pregnant women with bladder filled（group A） and pregnant women without bladder filled（group B） were all given two dimensional ultrasonic examinations.Birth weight and head circumference（group C） at birth were tracked.Results（1） The acquisition rate of biparietal diameter and standard section of head circumference in group A and group B were 88.7%（94/106） and 67.9%（72/106） respectively,and the difference was statistically significant（P0.05）.（2） The head circumferences of fetuses in group A,group B and group C were（338.2±17.9）mm,（332.7±14.6）mm and（342.0±18.5）mm respectively,and the body weights were（3 448±305）g,（3 307±311）g and（3 430±286）g respectively.The head circumference and body weight between group A and group C showed no statistically significant differences（P0.05）,but it showed statistically significant differences both between group A and group B and between group B and group C（P0.05）.（3） The biparietal diameters of fetuses in group A and group B were（93.1±10.5）mm and（90.8±6.9）mm respectively,and the difference was statistically significant（P0.05）.Conclusion The proper filling of bladder when having ultrasonic examination is conducive to obtaining the standard views of biparietal diameter and head circumference.Besides,it is also more accurate in detecting head circumference and body weight of the fetuses.
