To understand the risk factors for respiratory distress syndrome (RDS) by comparing the perinatal conditions of preterm infants with different severities of RDS.
A total of 667 preterm infants with RDS were classified into 4 groups according to the chest X-ray severity: grade I (217 cases), grade II (225 cases), grade III (126 cases) and grade IV (99 cases). The perinatal conditions of the preterm infants were reviewed retrospectively.
There were no significant differences in the gender, the percentage of twins, the percentage of the younger one in twins, maternal age, the percentage of using antenatal corticosteroids, the percentage of premature rupture of membranes, the percentage of placental abruption, the delivery mode and the fertilization mode in preterm infants with different severities of RDS. With the increasing severity of RDS, the birth weight and the gestational age decreased, and the percentage of the infants with Apgar score ≤7 or maternal pregnancy-induced hypertension increased (P<0.05).
The severity of RDS is related to gestational age, birth weight and perinatal asphyxia in preterm infants.
通过比较不同严重程度呼吸窘迫综合征（RDS）早产儿的围产期情况，了解RDS的危险因素。
将667例患有RDS的早产儿根据胸部X线严重程度分为4组：Ⅰ级（217例）、Ⅱ级（225例）、Ⅲ级（126例）和Ⅳ级（99例）。对早产儿的围产期情况进行回顾性分析。
不同严重程度RDS早产儿在性别、双胎比例、双胎中较小胎儿比例、母亲年龄、产前使用糖皮质激素比例、胎膜早破比例、胎盘早剥比例、分娩方式及受精方式方面差异均无统计学意义。随着RDS严重程度增加，出生体重和胎龄降低，Apgar评分≤7分的婴儿比例或母亲妊娠期高血压比例增加（P<0.05）。
早产儿RDS的严重程度与胎龄、出生体重及围产期窒息有关。
