【目的】通过检测早产儿生后3～5d及1月尿碘水平,评价本地区早产儿碘营养状态,以及时的干预。【方法】78例分别收集早产儿生后3～5d及生后1月晨尿10mL,采用离子色谱的方法进行尿碘检测。产科和儿科常规使用含碘消毒剂消毒皮肤,对尿碘异常者营养干预及减少碘暴露。【结果】78例早产儿生后3～5d,有45例碘营养适中,8例碘营养不足,25例碘营养过剩;生后1月尿碘值稍下降但无差异,碘营养适中59例,碘营养不足6例,碘过剩13例。顺产的早产儿尿碘水平高于剖宫产尿碘水平[(380.3±153.1)、(250.4±120.5)μg/L](P<0.05)。对尿碘异常者给予干预后,尿碘异常减少。【结论】本地区早产儿尿碘适中,对碘不足及过剩者干预可以及时纠正,早产儿尽量减少碘暴露。
【Objective】 To evaluate the iodine nutrition status of preterm infants in preterm infants by detecting the level of urinary iodine 3 ~ 5 days and January of preterm infants after birth, and timely intervention. 【Methods】 78 cases were collected 3 to 5 days after birth and 1 month after birth, respectively. The urinary iodine was detected by ion chromatography. Obstetric and pediatric routine use of iodine disinfectant disinfect the skin, urine iodine abnormal nutrition intervention and reduce iodine exposure. 【Results】 Among the 78 preterm infants, 3 to 5 days after birth, there were 45 cases of moderate iodine nutrition, 8 cases of iodine deficiency, 25 cases of iodine excess nutrition; after January urinary iodine value decreased slightly but no difference, moderate iodine nutrition in 59 cases , Iodine deficiency in 6 cases, iodine excess in 13 cases. The level of urinary iodine in preterm infants was higher than that in cesarean section [(380.3 ± 153.1), (250.4 ± 120.5) μg / L] (P <0.05). Urinary iodine abnormalities after intervention, urinary iodine abnormalities decreased. 【Conclusion】 Preterm infants in this area have moderate urinary iodine, which can be promptly corrected for intervention of iodine deficiency and excess. Premature infants can minimize iodine exposure.
