Investigation of preterm birth and preterm infants in Guangzhou regional district

Objective To investigate the incidence and relevant data of preterm birth and the outcomes of preterm infants delivered at different gestational weeks and for different causes.Methods A total of 997 women with preterm delivery in Huadu People's Hospital and Nanfang Hospital their 1 138 neonates of the previous mothers were enrolled as the research object in this survey from January 2005 to December 2010.The clinical features,maternal and neonatal outcomes were analyzed.Results(1) The incidence and constitute a premature than:six years of premature birth occurred in 10.6%(997/9 395).In the cause of premature birth order,PPROM of premature birth first(41.3%,412/997),the second was iatrogenic preterm(34.8%,347/997) and spontaneous preterm(23.9%,238/997).Cure source sex in premature main reason were preeclampsia in 154 cases(44.4%,154/347),lead the placenta in 72 cases(20.7%,72/347),fetal distress in 62 cases(17.9%,62/347),abruption in 34 cases(9.8%,34/347) and pregnancy with function mostly the function of 25 cases of disease(7.2%,25/347).(2) Pregnant weeks premature end with different:32 weeks premature mortality and complications of significantly higher than 32 to 34 weeks and frequency 34 weeks premature infants(P 0.05).Quartile 34 weeks premature cure rate was high,complications and death rate was significantly lower than the other two groups(P 0.05).(3) Different reasons and premature end:spontaneous preterm premature complications,the highest rate in the lowest,and the difference was statistical significance than other two groups(P 0.05).Iatrogenic preterm premature deaths,and the difference was statistical significance than other two groups(P 0.05).PPROM premature complications supreme,and the difference was statistical significance than other two groups(P 0.05).Conclusion Preterm birth before 32 weeks is associated with high perinatal mortality rate,which would be highlighted in prevention.Improved the prenatal care and antenatal care and timely detection of pregnancy complications should be implemented.Reduction of the iatrogenic preterm birth and proper prevention of PPROM are important measurements in decreasing the prevalence of preterm birth.
