Ratio of crown-rump distance to total length in preterm and term infants.
نویسندگان
چکیده
The known measurements for the determination of body proportions cannot be used practically in the neonate. The ratio of crown-rump distance to total length appears the most useful index for objective evaluation of disorders that influence body proportions in the neonate. Normal standards for this ratio in newborn infants from 27 to 41 weeks' gestation are presented in relation to gestational age and birth weight.

Background: Preterm infants frequently experience oral feeding difficulties due to undeveloped oral- motor skills and lack of coordination between sucking, swallowing and breathing. Infants’ ability to orally consume all feedings while maintaining physiological stability and weight gain is necessary for their discharge.

متن کاملComparison of Vitamin D Level in Preterm and Term Infant–Mother Pairs: A Brief Study
Background: Recent studies have demonstrated the high prevalence of vitamin D deficiency in the general population. Pregnancy and preterm delivery are known as risk factors for vitamin D deficiency. Consequently, vitamin D level in women with preterm deliveries might vary from those with term pregnancies. In this study, we aimed to compare vitamin D level in term and preterm infant–mother pairs...

We quantitated the growth patterns of the normal fetal heart and the right and left ventricles from postmortem hearts obtained from 55 spontaneously aborted human fetuses from the completion of cardiogenesis to term. Fetal gestational age was assessed by menstrual history of the mother, crown-rump length, head circumference, and body weight and ranged from 8 to 40 weeks. Each heart was perfused...
