Neonatal Assessment and Care

Overview

Neonatal Assessment and Care encompasses the comprehensive clinical examination and national screening programmes performed on every newborn infant within the first 72 hours of life to detect congenital abnormalities, birth injuries, and conditions requiring early intervention. The newborn physical examination is performed by a trained paediatrician or neonatal nurse practitioner and systematically evaluates all major organ systems. Early detection of conditions such as developmental dysplasia of the hip, congenital heart disease, congenital cataracts, and retinoblastoma is critical as treatment outcomes are dramatically better when initiated in the neonatal period before complications develop.

Types of Neonatal Assessment and Care

• Newborn physical examination — systematic head-to-toe clinical assessment within 72 hours of birth examining all major organ systems
• Newborn blood spot screening (heel prick) — dried blood spot sample collected at day 5 testing for 9 metabolic and endocrine conditions
• Newborn hearing screening — automated otoacoustic emission (AOAE) test performed before discharge from the maternity unit
• Pulse oximetry screening — pre- and post-ductal oxygen saturation measurement to screen for critical congenital heart disease
• 6 to 8 week check — second complete newborn examination performed by the GP including developmental assessment and first immunisations

Risk Factors of Neonatal Assessment and Care

• Prematurity (born before 37 weeks gestation) significantly increasing the risk of developmental, neurological, and metabolic complications
• Family history of congenital heart disease, metabolic conditions, or inherited genetic syndromes requiring targeted neonatal assessment
• Maternal infections during pregnancy (rubella, CMV, toxoplasmosis) that can adversely affect fetal development and neonatal health
• Difficult or traumatic delivery including prolonged second stage, shoulder dystocia, or instrumental delivery increasing birth injury risk
• Maternal diabetes increasing the risk of neonatal macrosomia, hypoglycaemia, respiratory distress, and cardiac anomalies
• Consanguinity or known carrier status for autosomal recessive metabolic conditions detected by newborn blood spot screening

Symptoms of Neonatal Assessment and Care

• Cyanosis (blue discolouration of the lips and tongue) suggesting critical congenital heart disease or respiratory compromise
• Absent or reduced femoral pulses on both sides suggesting coarctation of the aorta requiring urgent cardiac referral
• White or absent red reflex on ophthalmoscopy suggesting congenital cataract or retinoblastoma requiring urgent ophthalmology
• Hip clunk or instability on Barlow and Ortolani testing suggesting developmental dysplasia of the hip
• Failure to pass meconium within 24 hours of birth suggesting Hirschsprung's disease or anorectal malformation
• Jaundice (yellow skin and sclera) appearing within the first 24 hours of life suggesting haemolytic disease of the newborn
• Poor feeding, lethargy, and temperature instability in the first days of life suggesting neonatal sepsis or metabolic disease
• Abnormal muscle tone — either floppy (hypotonia) or stiff (hypertonia) — suggesting neurological injury or chromosomal abnormality
