Clinical Analysis Of 166 Cases In Medical-indicated Preterm Labor

Objective Objective to analyze the etiology of the the medical-indicated preterm labor delivery in our hospital.Analysis of the difference between the gestational weeks and the mode of delivery in the the medical-indicated preterm labor and other types of preterm labor.The effect of different use time and different gestational weeks on the pregnancy outcome of preterm infants in the the medical-indicated preterm labor.Methods Clinical records of 166 cases of premature delivery in the Affiliated Hospital of Binzhou Medical College obstetrics childbirth treatment from December,2016 to November,2017 are retrospectively analyzed,and 390 patients with spontaneous premature delivery period of delivery.The difference between the gestational weeks and the way of delivery is compared between the two types.Analysis of the causes of terminating pregnancy in the medical-indicated preterm labor,the effect of different time and different gestational weeks on the pregnancy outcome of preterm infants.The SPSS 17 software package is used for analysis and processing.The frequency data is represented by percentage(%).Chi square test is used to compare the count data.P<0.05 showed significant difference.Results(1)The cause in the the medical-indicated preterm labor:endemic diseases of pregnancy,pregnancy combined with internal and external diseases,prenatal hemorrhage and placental factors,twin pregnancy,uterine factors,fetal factors,oligohydramnios,etc.(2)The rate of cesarean section of the medical-indicated preterm labor is 96.39%,and the rate of spontaneous premature delivery is only 27.18%.However,the rate of cesarean section is 47.84%for the total preterm labor.(3)There is no significant difference in the distribution of gestational weeks between two types of preterm birth,and the selection of the same type of premature delivery is not significantly related to the gestational age.The patients who terminated the pregnancy for more than 34 weeks of pregnancy accounted for 65.66%of the preterm labor.(4)The incidence of asphyxia and NRDS in preterm infants decreased with the prolongation of gestational weeks.The rate of asphyxia and the incidence of NRDS in preterm infants decreased significantly after 34 weeks of pregnancy.(5)The effect of reducing the incidence of NRDS is more than 24 hours after the termination of pregnancy.Conclusion(1)The causes of the medical-indicated preterm labor are multifarious.(2)There is no significant difference between therapeutic preterm delivery and natural preterm delivery in gestational weeks,and there was no significant difference between the choice of delivery modes and gestational weeks.(3)The main way to terminate pregnancy in the the the the medical-indicated preterm labor is cesarean section.Natural premature delivery mainly terminates pregnancy by vaginal delivery.Meanwhile,for patients with total preterm labor,vaginal delivery is still the main reason,probably because natural premature labor is still the main type of preterm birth.(4)After evaluating the prognosis of mother and fetus,most of the weeks of termination of pregnancy are more than 34 weeks,indicating that human intervention played a certain role.(5)Therefore,if the mother and child are still stable,we should try to prolong the gestational weeks.And try to terminate pregnancy 24 hours to 7 days after the treatment of fetal lung maturation,improve the survival rate of preterm infants and reduce the rate of disability.
