Factors Affecting The Residual Of Postpartum Placenta And Treatment Analysis

Objective:To explore and analyze the risk factors affecting the residual of postpartum placenta,and to analyze the risk factors by non-conditional Logistic regression analysis method,then to make the scientific and reasonable prevention and treatment strategies of the independent risk factors of the results.Methods:880 cases of full term pregnant women of vaginal delivery in our hospital from January 2014 to October 2015 were selected, including 58 cases of postpartum placental residue, and 822 cases without postpartum placental residue.The former were as observation group,and the latter were as cintrol group.The factors that may result in the post natal placenta residue were determined by the single factor analysis method,and the factors affecting the degree of the more significant factors were analyzed by the non-conditional Logistic regression analysis method.According to the independent risk factors in the analysis results,the preventive measures were formulated to reduce the risk of the occurrence of the placenta,and the treatment of the patients with placental residues should be treated in time.Results:(1)The factors that may affect the residual of postpartum placenta factors of were analyzed by non-conditional Logistic regression analysis and rank sum methods, and the results show that there were no differences in the factors such as prenatal body mess index more than or equal to 28kg/m2,gestation more than or equal to 37 weeks, births, postpartum bleeding,birth time, total birth times and the body mess of newborns between the two groups(P>0.05),while the differences in the factors such as age more than or equal to 35 years old,complicated gestational diabetes mellitus,pregnancy complicated with hypertension,this pregnancy from the last time less than or eaqual to 2 years,history of abortion, natural childbirth the third production process time, uterine atony, uterine atony complicated with postpartum hemorrhage, scar uterus, placenta mode of delivery, mode of delivery, placenta, postpartum injection contractions more than or equal to 2d and so on between the two groups were statistically significant(P < 0.05).(2)The risk factors of postpartum placental residue are ranked according to the degree of danger:natural childbirth the third production process time(OR=10.945), postpartum bleeding more than or equal to 500ml(OR=10.045),uterine inertia(OR=9.864), scar uterus(OR=7.162), Hand stripping placenta(or=8.152), postpartum injection contractions less than 2d(OR=6.418), this pregnancy from the last time less than or eaqual to 2 years(OR=6.214), history of abortion(OR=6.187), pregnancy complicated with hypertension(OR=5.483), complicated gestational diabetes mellitus(OR=4.264), age more than or equal to 35 years old(OR=2.481) and so on were the independent risk factors of postpartum placental residues.Conclusion:(1)Analysis of the risk factors of postpartum placenta residue had significant ly important clinical significance for preventing patients witht postpartum placental residue.(2)The risk factors of postpartum placental residue are ranked according to the degree of danger:natural childbirth the third production process time(OR=10.945), postpartum bleeding more than or equal to 500ml(OR=10.045),uterine inertia(OR=9.864),scar uterus(OR=7.162), Hand stripping placenta(or=8.152), postpartum injection contractions less than 2d(OR=6.418), this pregnancy from the last time less than or eaqual to 2 years(OR=6.214), history of abortion(OR=6.187), pregnancy complicated with hypertension(OR=5.483), complicated gestational diabetes mellitus(OR=4.264), age more than or equal to 35 years old(OR=2.481) and so on.(3)We should be accordance with to develop personalized coping strategies in the clinical treatment of pregnant women with the above factors.Do not prematurely over forcibly knead crowded uterine, and the tocolytic agents should be given according to the delivery of the placenta process, as well as in the production process of intravenous injection of oxytocin).Postpartum can be injected oxytocin, in order to facilitate the removal of the remaining placental tissue fragments in vitro.
