Neonatal Disorders Flashcards
Problems related to prematurity
- Temperature Regulation
- Infection
- Feeding
- Hypoglycaemia
- Apnoea
- Jaundice
Complications of prematurity
Necrotising enterocolitis
- Patent ductus arteriosus
- Retinopathy of prematurity
- Damage dt immature CNS
Respiratory stress syndrome causes
Due to surfactant deficiency of abnormality
•Usually due to prematurity
•Surfactant abnormality may be seen in babies born to diabetic mothers and those who have rhesus isoimmunisation.
•Elective caesarian exacerbates the condition.
Presentation RDS
- Increased WOB
- Signs of respiratory distress.
- X-ray diffuse symmetrical reticular granular pattern with air bronchograms.
- Clinical signs present from 4 hours after delivery.
- Regardless of prematurity surfactant will be produced at 48 hrs post delivery, the condition is therefore self limiting as long as secondary
Treatment of RDS
Supportive
•Exogenous surfactant
•Antibiotics
Prevention
•Beta-2 stimulants to mother if premature labour is expected (amonophylline, steroids, thyroxin and thyrotropic releasing hormone)
•Exogenous surfactant given to the baby at birth.
Chronic lung Disease
Infants who are still oxygen dependent at one month are defined as having neonatal chronic lung disease (CLD I). A small proportion of these have cystic changes on x-ray and they are classified as having bronchopulmonary dysplasia (CLD II).
•Those with BPD remain oxygen dependent for many months and often require home oxygen
Causes of CLD
Multi-factorial and includes prematurity, genetic predisposition and low antioxidant status.
•High inspired oxygen concentrations and ventilation at high pressures increase risk.
•Also associated with development of a PDA as well as with cytomegalovirus.
CLD
Prevention
•High frequency oscillation ventilation may be helpful.
Management
•Wean infants ASAP
•Nebulise with caution as often get paradoxical deterioration in lung function with deoxygenation prior to bronchodilation. A metered dose inhaler with a spacer does not
Physio mx of neonate
MINIMAL HANDLING
• No routine therapy
•Assess each infant individually
• Retention of secretions and lobar collapse due to plugging are the main indications for chest physio.
Indications of PT
Meconium aspiration
- Aspiration of feed or vomit
- Chronic lung disease
- Postoperatively
CI PHYSIO
- Unstable infant
- Pulmonary haemorrhage
- Respiratory distress syndrome
Physiotherapy techniques
Positioning and postural drainage •Percussion and vibration •Manual hyperinflation •Suction •Saline installation
