Clinical Analysis Of287Cases Of Preterm Premature Rupture Of Membranes’

ObjectiveSpontaneous preterm is a common complication of pregnancy, including spontaneous preterm delivery and premature rupture of membranes in spontaneous abortion. The incentives of spontaneous preterm is complex.Domestic and foreign research data shows:premature rupture of membranes in spontaneous preterm is often the result of the interaction of a variety of factors,for example:premature rupture of membranes, intrauterine infection, lower genital tract and urinary tract infections, uterine expansion. Among them the excessive and endocervix relaxation is the main incentive. Premature rupture of membrane in spontaneous abortion incentives are extremely complex,.The clinical treatment of which is just symptomatic treatment, The time of pregnancy termination in particular is still in the exploratory stage. This study, a retrospective analysis of the past-patient medical records, summarized and analyzed the impact of child pregnancy outcome related factors,in order to make a reference for the clinical timing of delivery.Thus,improve PPROM pregnancy outcomes and reduce the perinatal child morbidity and mortality reference.MethodsSelect the samples from hospitalized delivery patients in the First Affiliated Hospital of Zhengzhou University from March2008to March2012, including287preterm prerupture of membranes cases and119spontaneous premature rupture of membranes cases. Extract the hospitalization information of the spontaneous preterm,then filter the information in accordance with the diagnostic criteria for spontaneous preterm and eliminating standards. At last,find,analyze and registration the observed parameters to analyze.ResultsLower genital tract infection incidence is higher in the observation group than the control group(P<0.05).The highest proportion in the lower genital tract infection is mycoplasma infection, followed by HPV infection.Uterine malformations,cephalopelvic disproportion, intrauterine pressure increase (multiple pregnancy, polyhydramnios) are associated with the occurrence of spontaneous preterm.Results of the comparison of the two sets of mode of delivery and gestational age are following.First,the vaginal delivery rate in the observation group was higher(P<0.05).Second,in both groups,gestational week>34w pregnant women’s cesarean rate higher than the gestational week <34w pregnant women (P <0.05).Third,puerperal infection rate was higher in the observation group (P <0.05).Fourth,in observation group, postpartum haemorrhage, retained placenta incidence rate higher than that of the control group (P<0.05).Fifth,Two sets of with, the difference of the gestational week in vaginal delivery patients was not statistically significant (P>0.05).Sixth, among patients with vaginal delivery, the incidence of fetal distress and abnormal labor had an increasing trend compared with the observation group, but the difference was not statistically significant (P>0.05). The outcome of perinatal children of these two groups will displayed later.First,the neonatal infection rate was higher in the observation group (P<0.05).Second,the incidence of hyaline membrane disease is higher in the observation group (P <0.05).Third,neonatal asphyxia rate of the observation group had an increasing trend, but the difference was not statistically significant (P>0.05).Fourth,the Apgar <7points, neonatal asphyxia, neonatal hyper-bilirubinemia, neonatal meconium aspiration syndrome, perinatal child mortality incidence of the observation group had an increasing trend, but the difference was not statistically significance (P>0.05).Conclusions1.The lower genital tract infection is the most common incentives of PROM.2.The incidence rates of neonatal infection in PPROM group is higher than in PROM group, but the incidence rates of neonatal pulmonary hyaline membrane disease is lower. The mortality of neonatal in the two groups has no difference.
