The Analysis Of Related Factors About The Prevent The Fetus Of Late Threatened Abortion

Objective: Analysising the related factors about the prevent the fetus result of latethreatened abortion,it is aim to as soon as possible to find the reason、early interventiontreatment, to improve the success rate of prevent the fetus, and to avoid the happeningof the inevitable abortion.Method:Among couples coming to da lian maternity hospital from April2012toMarch2013,we selected a total of227patients with late threatened abortion who wereto receive the treatment of prevent the fetus.among these181successful prevent thefetus cases, success rate of79.7%;46cases of inevitable abortion, prevent the fetusfailure rate of20.3%.All patients admitted to hospital with a detailed history, parallelroutine blood, CRP, thyroid function, virus, ultrasonic, vaginal and cervical secretionculture, analysising of factors that may affect Protect the fetus end.Statistical analysiswas performed using the SPSS17.0software.measuring data by using t test, countingdata by chi-square test, multi-factor analysis using the unconditioned Logisticregression analysis, predictive value using ROC analysis of diagnostic test, P valuesof <0.05were consedered significant.Results:1, Comparing prevent the fetus successful group with the inevitableabortion group, there is no statistical difference in average age, gestational age, but it islonger length of hospital stays in prevent the fetus successful group (P <0.05); Thereis statistically difference in anemia, RSA, infection, and cervical insufficiency aftercervical cerclage between the two groups(P <0.05); Multi-factor unconditionedLogistic regression analysis showed that infection, cervical insufficiency after cervical cerclage statistically difference (P <0.05), infection is the independent risk factor forinevitable abortion OR=5.796.cervical insufficiency after cervical cerclage isindependent protection factors for inevitable abortion OR=0.076; comparing betweenthe two groups, mycoplasma, active syphilis were statistically difference (P <0.05);As the increase of WBC、neutrophil percentage、neutrophils absolute value、CRP value,in the inevitable abortion rate was up,prevent the fetus success rate was down, whichwere both statistically different(P <0.05); As the increase of WBC, neutrophilpercentage, neutrophils absolute value,CRP value in the inevitable abortion rate was up,prevent the fetus success rate was down, which were both statistically different(P <0.05).Conclusion:1, The factors affecting prevent the fetus ending of the late threatenedabortion were anemia, RSA, infection, cervical insufficiency after cervical cerclage,and infection is independent risk factors for inevitable abortion, cervical insufficiencyafter cervical cerclage is independent protection factor for inevitable abortion.2,When late threatened abortion patients were infected with mycoplasma,syphilis inactive period, inevitable abortion rate increased.3.The higher the value of late threatened abortion patients WBC,neutrophils,CRP,thelower prevent the fetus success rate, the higher the inevitable abortion rate.4, WBC、neutrophils and CRP provided a moderate predictive value on the inevitableabortion, and it provided a certain basis for clinical doctors to use antibiotics, and CRPof inevitable abortion predictive value is the largest.
