Premature infants typically weigh less than 2.5 kilograms at birth and have weaker immune systems, requiring particularly attentive care. Focusing on the six major complications associated with prematurity is crucial for ensuring proper postnatal feeding and nursing of these infants.
1. Cardiovascular Diseases:
As lung issues gradually improve, the persistent open ductus arteriosus allows excessive blood flow from the aorta to the lungs, potentially causing heart failure and impaired lung function.Some extremely low birth weight infants may also develop respiratory distress syndrome, presenting with rapid breathing and cyanosis.
3. Gastrointestinal Disorders:
Premature infants are prone to malabsorption issues, making breast milk the preferred feeding option. If formula substitution is necessary, it should be introduced gradually in small, incremental amounts.Additionally, a very small percentage of preterm infants develop necrotizing enterocolitis, which requires specialized treatment. 4. Periventricular and Intraventricular Hemorrhage: Due to the immature structure of the ventricles and fragile blood vessels in the brains of preterm infants, increased intracranial pressure can easily cause rupture and bleeding.These are generally classified into four grades. Mild hemorrhages that do not cause ventricular enlargement are often absorbed by the brain. However, significant bleeding leading to ventricular enlargement or spreading into brain tissue may impair neurological function, resulting in delayed motor development or behavioral disorders. A brain ultrasound should be performed after birth, with regular follow-up examinations if issues are detected.
5. Retinopathy of Prematurity (ROP):
Prematurity may disrupt normal development of retinal blood vessels, leading to eye abnormalities and increased susceptibility to nearsightedness. Regular follow-up examinations at a pediatric ophthalmology clinic are recommended.
6. Infections:
Premature infants possess underdeveloped immune systems, making them vulnerable to viral infections. Infections can rapidly progress to sepsis or even meningitis, requiring close monitoring.
