摘要: 背景 呼吸窘迫综合征(RDS)是导致早产儿死亡的重要原因,需不断加强临床预防及治疗,但目前关于脐血维生素A、E水平与早产儿发生RDS的关系研究报道较少。 目的 探讨脐血维生素A、E水平与早产儿发生RDS的关系。 方法 选取2021年1月—2022年1月在石家庄市第四医院出生的早产儿304例,根据RDS发生情况将其分为RDS组120例与非RDS组184例。收集与早产儿发生RDS可能相关的临床特征并检测脐血维生素A、E水平;早产儿发生RDS及RDS严重程度的影响因素分析采用多因素Logistic回归分析。 结果 RDS组早产儿胎龄、出生体质量小于非RDS组,1 min Apgar评分≤7分比例、5 min Apgar评分≤7分比例、维生素A缺乏发生率高于非RDS组,脐血维生素A、E水平低于非RDS组(P<0.05)。RDS组早产儿中轻症86例,重症34例;重症RDS早产儿脐血维生素A水平低于轻症RDS早产儿,维生素A缺乏发生率高于轻症RDS早产儿(P<0.05)。多因素Logistic回归分析结果显示,脐血维生素A水平为早产儿发生RDS的影响因素〔OR=2.208,95%CI(1.156,4.218),P<0.05〕;维生素A缺乏为早产儿发生重症RDS的影响因素〔OR=6.835,95%CI(2.537,18.416),P<0.05〕。 结论 发生RDS的早产儿脐血维生素A、E水平较低,脐血维生素A水平为早产儿发生RDS及其严重程度的影响因素,建议在妊娠期适当补充维生素A以减少早产儿RDS的发生及减轻其严重程度。

Abstract:

Background

Respiratory distress syndrome (RDS) is an important cause of death in preterm infants, which needs to be constantly strengthened in clinical prevention and treatment, but the relationship of umbilical cord blood vitamin A and E levels with the development of RDS in preterm infants has been rarely reported.

Objective

To investigate the relationship of vitamin A and E levels in umbilical cord blood with RDS in preterm infants.

Methods

A total of 304 preterm infants in the Fourth Hospital of Shijiazhuang from January 2021 to January 2022 were selected and divided into the RDS group (n=120) and non-RDS group (n=184) according to the incidence of RDS. Clinical features that may be related to the occurrence of RDS in preterm infants were collected, vitamin A and E levels in umbilical cord blood were detected. Multivariate Logistic regression analysis was used to analyze the influencing factors of the occurrence and severity of RDS in preterm infants.

Results

The gestational age, birth weight, vitamin A and E levels in umbilical cord blood of preterm infants in the RDS group were lower than those in the non-RDS group, the proportions of newborn's Apgar score in one-minute≤7, newborn's Apgar score in five-minute≤7, and incidence of vitamin A deficiency were higher in the RDS group than those in the non-RDS group (P<0.05). There were 86 cases with mild RDS and 34 cases with severe RDS in the RDS group; the vitamin A level in umbilical cord blood in cases with severe RDS was significantly lower than cases with mild RDS, while the incidence of vitamin A deficiency was significantly higher than cases with mild RDS (P<0.05). Multivariate Logistic regression analysis showed that vitamin A level in umbilical cord blood was the influencing factor of the occurrence of RDS in preterm infants〔OR=2.208, 95%CI (1.156, 4.218), P<0.05〕, and vitamin A deficiency was the influencing factor of the occurrence of severe RDS〔OR=6.835, 95%CI (2.537, 18.416), P<0.05〕.

Conclusion

Vitamin A and E levels in umbilical cord blood are relatively lower in preterm infants with RDS, vitamin A level is the influencing factor of the occurrence and severity of RDS in preterm infants, suggesting that vitamin A supplementation should be applied during pregnancy to reduce the occurrence or severity of RDS in preterm infants.
