The Analysis Of The Factors Related To Preterm Infants Asphyxia

Objective:To analysis the factors related to the preterm infants asphyxia andprovide clinical guidelines for the treatment of preterm labor.Methods：1.Statistics the maternal age, gestational weeks, complication，themode of delivery and whether associated with premature rupture ofmembranes(PROM) of preterm birth born in Second Hospital Affiliated toChongqing Medical University from January2012to February2014，toanalysis the factors effect on preterm infants asphyxia by Logisticregression.2.185cases of preterm premature rupture of membranes (PPROM)are grouped according to the membrane rupture time, correcting otherrelated factors on the effects of preterm infants asphyxia, to evaluate theeffect of the membrane rupture time on the preterm infants asphyxia.Results: Collected589cases associated with preterm birth, eliminateunqualified medical records43cases,92cases of twins are excluded,selected to meet the requirements of454premature cases included in thestatistics, the results are as follows: 1. Maternal age had no significant effect on preterm infants asphyxia(p>0.05).2. The smaller gestational age, the greater probabilityof occurrence of the preterm infants asphyxia (p <0.05, the regressioncoefficient is-0.8939).3. The pregnant women complicated with HDCP, GDM, ICP,hypothyroidism, hyperthyroidism, congenital heart disease, scarring of theuterus, placenta accrete, true umbilical cord knot and other complicationshave significant affect on the rate of preterm infants asphyxia, Theoccurrence probability of preterm infants asphyxia in pregnant women whowere merged complications during pregnancy is3.832fold than thepregnant women without complications (p <0.05, OR value=3.832).4. The mode of delivery has significant affect on the rate of preterminfants asphyxia. The probability of preterm infants asphyxia in preterminfants who were delivered by uterine-incision delivery is2.125fold thanthe preterm infants who were delivered by vaginal birth (p <0.05, ORvalue=2.125).5. PROM has no obvious effect on preterm infants asphyxia (p>0.05),but the membrane rupture time has effect on the probability of preterminfants asphyxia, the longer the time of rupture of membranes, the greaterthe probability of preterm infants asphyxia (p<0.05).Conclusions:Fetal gestational age, mode of delivery, pregnant women merged complications and the membrane rupture time were all the influencingfactors of preterm infants asphyxia, and maternal age had no significanteffect on preterm infants asphyxia.
