目的探讨小于胎龄儿产科的高危因素及围生期并发症发生情况。方法对540例早产儿,其中小于胎龄儿(SGA)74例,适于胎龄儿(AGA)466例,进行产科高危因素分析并比较围生期各种并发症的发病率。结果妊娠合并多胎妊娠、妊高征、孕母来自农村发生率SGA组高于AGA组(P<0.05)。围生期新生儿窒息、颅内出血、急性坏死性小肠结肠炎(NEC)发生率SGA组高于AGA组(P<0.05)。Logistic回归分析显示妊高征、贫血、多胎妊娠、孕母职业是小于胎龄儿产科的高危因素。结论妊高征、贫血、多胎妊娠、孕母职业可能是小于胎龄儿产科的危险因素。应注重妊娠期合并症及围生期并发症的治疗。
Objective To investigate the risk factors of obstetrics in infants younger than gestational age and the incidence of perinatal complications. Methods A total of 540 preterm infants, including 74 small gestational age (SGA) and 466 gestational age children (AGA), were included in this study. The risk factors of obstetrics were analyzed and the incidences of various complications during perinatal period were compared. Results Pregnancy complicated with multiple pregnancy, pregnancy-induced hypertension, pregnant women from the rural incidence of SGA group was higher than AGA group (P <0.05). Perinatal neonatal asphyxia, intracranial hemorrhage, and acute necrotizing enterocolitis (NEC) were higher in the SGA group than in the AGA group (P <0.05). Logistic regression analysis showed that pregnancy-induced hypertension, anemia, multiple pregnancy and maternal occupation were risk factors of obstetrics in gestational age. Conclusion Pregnancy-induced hypertension, anemia, multiple pregnancies and maternal occupations may be risk factors for obstetrics and gynecology in infants younger than gestational age. Should pay attention to complications of pregnancy and perinatal complications of treatment.
