Essay about Development Of Preterm Infant : Definition Of Prematurity
Definition of prematurity:
Preterm birth is known as an early delivery done before the 37th week of gestational age. The burden of preterm newborns has been rising during the last 20 years worldwide (Acolet et al., 1993).
Problems of prematurity: Preterm infants have a smaller birth weight than full-term infants and also have feeding difficulties due to suckling troubles or incoordination of swallowing and breathing. Also, neonatal intensive care unit (NICU) admitted premature infants are exposed to many stressful conditions that can affect their weight. In addition, weight gain becomes the main criteria for hospital discharge following intensive care treatment (Beck et al., 2010). Premature infants are at risk of poor growth during admission and after discharge from the NICU. Close monitoring and subsequent interventions also required to promote growth (Mansor et al., 2012).
Growth abnormalities during early infancy may persist into adulthood, especially in patients who were preterm infants. This was reported in a study of very low birth weight (VLBW, <1500 g) infants, where authors found them to have a height less than the third percentile at 20 years of age than that of normal birth weight controls (10 versus 5 percent) (Hack et al., 2002).
The fetal acquisition of nutrition from mother is divided into 3 phases:
1. Absorption phase: Zygote is nourished by cellular cytoplasm and…
