Prematurity and High-Risk Infants
Introduction[edit | edit source]
Prematurity is a significant healthcare problem occurring on over 10% of live birth every year.[1] The World Health Organization (WHO) estimates there are 15 million preterm births every year. [2] The WHO categorizes preterm birth into the following three categories:
- extremely preterm (< 28 weeks)
- Very preterm (28–32 weeks)
- Moderate to late preterm (32–36 weeks)[3]
Complications of Preterm Birth[edit | edit source]
Preterm infants have an increased risk for neurodevelopmental disorders and delayed growth with some developing neurological sequelae such as cerebral palsy, decreased intelligence and delayed neurodevelopment.[4]Neurodevelopment and growth in preterm infants can be affected by:
- gestational age
- birth weight
- length of hospitisation
- Apgar score
- cardiopulmonary resuscitation (CPR)
- ventilation
- breastfeeding[4]
Infants born at an earlier gestational age are at a higher risk for complex medical conditions, recurrent hospitisations and neurodevelopmental impairments,[5]. Developmental delays and chronic diseases that result from preterm birth may persist into adulthood and consequently, require a heavy burden on the patients, families and healthcare system.[4]
Neonatal Intensive Care Unit (NICU)[edit | edit source]
[1,2]. I[1]. Preterm infants face several challenges during their neonatal intensive care unit (NICU) stay, including cardiorespiratory problems, infections, and neurological challenges, while continuing to grow and attain neurodevelopmental milestones for NICU discharge [3]. [4].[1]
Complications[edit | edit source]
Due to a shortened period of in utero organ development, premature infants are at higher risk of chronic respiratory, cardiac, renal, and endocrine system disorders later in life.
s the third trimester of pregnancy (> 28 weeks) is a period of rapid organ growth and maturation, premature infants are born before major organ development is complete. Survivors of premature birth may have later adverse health effects related to organs failing to achieve optimal development or undergoing more rapid decline.10[3]
