Ultrasonic Measure Fetal Collarbone Length Predict Fetal Birth Weight Of Research

Purpose:To study ultrasound diagnostic instrument measurement fetal collarbone length Predictclinical value of fetal birth weight,Provide reference data for clinical research.Methods:The clinical tests, using high resolution four dimensional color spectrum were of diagnosticinstrument (GE Voluson8).Use the color doppler ultrasound diagnostic instrument to pregnantwomen in before childbirth0~3days measurement data:(1) Records of100cases of pregnantwomen age, fetal weeks of gestation, use electronic scales after birth weight newborn record thedata,use electronic accounting weight newborn (error <10g),born in implementation of5min;also recorded after birth of neonatal collarbone length.(2) After the birth of clavicle newbornlength and after birth weight newborn data with SPSS13.0package statistical analysis,concluded between the linear regression equation.(3) In addition we acquisition in45casespregnant women and fetal measurement data,and verify the feasibility of the formula. fetalestimated weight data and the length of clavicle use the repetitive measure method,Each datameasured three times, take the mean to record.Result:1)At37to42weeks fetal an average length of clavicle2.95±0.41cm,a range of2.20~3.80cm.2)Different birth weight group of clavicle length overall difference fetus a statisticallysignificant (F=10.759, P <0.001).The birth weight of clavicle length that are:Fetus birth weightfor2500~g,collarbone length is2.49±0.25cm；fetus birth weight for3000～g,collarbonelength is2.87±0.35cm；fetus birth weight for3500～g,collarbone length is3.11±0.39cm；fetus birth weight for4000～g,collarbone length is3.42±0.16cm.3) Linear regression statistics analysis shows that: b＝468.857, P <0.001,linear regressionequationY2031.696468.857X,the formulaY for fetus birth weight (g), X for fetus birthlength of clavicle(cm); fetus birth of clavicle length and fetus birth weight between werepositively correlated (r＝0.568, P <0.001).4)45cases in the results of the validation, fetal weight estimation formula standard has32cases, accounting for71.1%. Conclusion:1.A new way to measure fetal clavicle prediction feasibility fetal weight length.2.The new method is easy to operate.3.Ultrasonic physicians operation level and fetal position has certain requirements.
