1. The Neonatal Period

2. Be able to define the neonatal period Know how and when jaundice can present and when to initiate treatment Be able to recognise gastro-oesophageal reflux and how to advise parents Be able to answer MCQs and clinical image questions Learning Outcomes

3. For term infants the neonatal period lasts from birth until 28 days of age For pre-term infants the neonatal period extends from birth to 44 post-menstrual weeks of age Neonatal Definitions

4. Pre-term = born before 37 completed weeks of gestation, accounting for 10% of births Term = born between 37 and 42 completed weeks of gestation Post-term = born >42 completed weeks of gestation, accounting for less than 5% of births Neonatal Definitions

5. Neonatal Jaundice

6. Yellow discoloration of sclera and skin Due to accumulation of bilirubin May indicate serious underlying disease Neonatal Jaundice

7. Physiological jaundice: – Presents at 2-3 days of age – In an otherwise healthy infant – Often associated with difficulty establishing feeds – Usually resolves within 2 weeks Neonatal Jaundice

8. Early jaundice: – Within 24 hours of birth – Always pathological Prolonged jaundice: – Lasts >14 days in term/>21 days in pre-term infants – Most common cause is breast milk jaundice Conjugated jaundice: – Usually due to neonatal liver disease Neonatal Jaundice

9. Investigation varies depending on: – Age at presentation – Duration of symptoms Investigations may include: – Bilirubin (conjugated/unconjugated/total) – FBC, blood group and DCT – U+Es Neonatal Jaundice

11. Management involves; – Treatment of the underlying cause – Correction of hyperbilirubinaemia Phototherapy Exchange transfusion Untreated jaundice may lead to kernicterus Neonatal Jaundice

12. Gastro-oesophageal Reflux

13. Non-forceful regurgitation of gastric contents into the oesophagus Occurs due to incompetence of gastro- oesophageal sphincter If persistent may result in gastro-oesophageal reflux disease Gastro-oesophageal Reflux

14. Presenting signs & symptoms include: – Non-forceful regurgitation – Irritability – Resistance and arching with feeding – Failure to thrive – Apnoeas – Cough and stridor Gastro-oesophageal Reflux

15. Diagnosis is clinical Potential investigations: – FBC – 24 hour oesophageal pH study – Manometry – Barium meal – Endoscopy Gastro-oesophageal Reflux

16. Management: – Conservative Reassurance, not overfeeding and upright positioning – Medical Thickeners, anti-regurgitation formula, gaviscon H2 receptor antagonists, proton pump inhibitors – Surgical Gastro-oesophageal Reflux

43. Neonatal jaundice is common Common causes include physiological jaundice and breast milk jaundice Jaundice in the first 24 hours is always pathological Treatment may be conservative, phototherapy or exchange transfusion Untreated may lead to disability and death Prognosis in the developed world is excellent Key Facts: Neonatal Jaundice

44. Non-forceful regurgitation after feeds Presents between 1-4 months of age If persistent may lead to GORD Management is usually conservative Usually resolves by 10-18 months Key Facts: Reflux
