虽然Gesell等曾对早产儿肌张力和反射的评估做过阐述,但受到当时条件的限制,胎龄28至32周前存活儿极少。由于产科和儿科护理水平的提高,提高了胎龄23至24周早产儿存活的可能性,存活者多无严重缺陷。本文是关于极小早产儿肌张力及反射的研究报道。方法对象为42名1983年生,体重<1300g的早产儿;胎龄24～32周(2/3≤28周)。黑人占71%随访均无脑瘫。生后1周起由个儿神经病学家每周对肌张力和反射发育系统检查一次,直至出新生儿监护中心(NICU)。以经后龄(胎龄+周龄)记录发育情况平均观察至38周。上下肢发育差异应用配对t检
Although Gesell et al. Described the assessment of muscle tone and reflexes in preterm infants, it was limited by prevailing conditions and there were very few surviving babies between 28 and 32 weeks of gestation. Due to the improved obstetric and pediatric care, the chance of surviving preterm infants at gestational age 23 to 24 weeks is increased, with no serious defects among survivors. This article is about the study of muscular tension and reflex in very young premature infants. METHODS: Forty-two preterm infants with a birth weight of <1300g were enrolled in 1983 and gestational age ranged from 24 to 32 weeks (2 / 3≤28 weeks). Blacks accounted for 71% of the patients without cerebral palsy. Week 1 week after the onset of neurological neurologist once a week on the muscular tension and reflex development system until a neonatal care center (NICU). The postnatal age (gestational age + week age) records the development of the average observed until 38 weeks. Application of paired t test on differences in upper and lower limb development
