10 mins - 85-90%
choanal atresia
- congenital anomaly of the nasal cavity in which there is narrowing of one or both nasal passages. As newborn babies breathe through their nose, in bilateral choanal atresia there is immediate obstructive breathing that is relieved only when the baby cries
micrognathia - pierre robin sequence
- triad of features that cause respiratory compromise
- small jaw, large tongue and cleft palate
- risk of resp distress 3x greater at 37 weeks compared to 39-40 weeks
RDS and hyaline membrane disease
- caused by inadequate production of surfactant in the lungs.
- Surfactant is normally produced by type II pneumocytes and has the property of lowering surface tension. Most alveolar surfactant is produced after 30 weeks of gestation. Inadequate surfactant production causes air sacs to collapse on expiration and greatly increases the energy required for breathing
- Leads to hypoxia and retention of co2
- Signs = tachypnoea, expiratory grunting, diminished breath sounds, cyanosis and nasal flaring
transient tachypnoea
- Aka wet lung
- retained fetal lung fluid and can be complicated by a mild surfactant deficiency. It is more common in infants born by caesarean without labour
- rapid breathing, nasal flaring, sternal recession, grunting and cyanosis
meconium aspirate syndrome
- breathes a mixture of meconium and amniotic fluid into the lungs around the time of birth. it occurs rarely in infants born at less than 36 weeks gestation. In approximately 10%–15% of labours there is meconium-stained amniotic fluid (MSAF). The majority of infants born through MSAF will experience only mild respiratory distress that resolves over 24–48 hours
chronic lung disease
- need for either mechanical ventilation or CPAP and / or receiving supplemental oxygen at a corrected gestational age of 36 weeks or beyond the 28th day of life. It is a multifactorial condition
- mechanical ventilation, prematurity, severity of respiratory distress syndrome, oxygen toxicity, patent ductus arteriosus, inflammatory changes in the lung and duration of mechanical ventilation
air leak syndrome
- Pneumothorax is a lung disorder in which air in the lungs leaks out through holes in the lung tissue into the spaces outside the lung airways
- pneumothorax —air leaks into the space between the chest wall and the outer tissues of the lungs
pneumomediastinum
air leaks into the mediastinum (the space in the thoracic cavity behind the sternum and between the two pleural sacs containing the lungs)
pneumopericardium
air leaks into the sac surrounding the heart
pulmonary interstitial emphysema (PIE)
air leaks and becomes trapped between the alveoli, the tiny air sacs of the lungs
Congenital diaphragmatic hernia
- defect in the diaphragm muscle with herniation of the abdominal contents into the thorax through the defect.
- pulmonary hypoplasia (PH), the response to artificial ventilation and the presence of therapy-resistant pulmonary hypertension
oesophageal atresia
- congenital anomaly in which the oesophagus ends in a blind pouch
- 85% of cases it is associated with a fistula (connection) between the trachea and the oesophagus
Pneumonia
- a form of acute respiratory infection that affects the lungs.
- PROM, maternal fever, chorioamnionitis risk factors
- GBS (poor feeding, lethargy, cyanosis) bad resp signs
- Chest x-ray, FBC, blood cultures, arterial blood gases IV abx
apnoea
- No resp effort for more than 20 secs
- Not accompanied by cyanosis or brady
- Pre-term infants of <34 weeks = admin methylxanthine (caffeine citrate or aminophylline) – smooth muscle relaxant and a cardiac muscle and CNS stimulant
circulation
- Colour in presence of a patent airway and adequate ventilation is useful in assisting diagnosis
- Cyanotic – indicate congenital heart disease
- Pallor indicates shocks and haemorrhage
- Yellow – severe ABO incompatibility
congenital heart disease
transposition of the great arteries
- Most common approx. 5% of all CHD cases
- Two circulations – the pulmonary artery arising from the left ventricle and the aorta from the right ventricle
- Severe cyanosis is important clinical sign and immediate arterial oxygen sats should be recorded
- Chest x-ray shows ‘egg on the side’ outline of the heart – echo for diagnosis
- Intact ventricular septum and no atrial communication is a cardiac emergency – needs balloon atrial septostomy – commence prostaglandin and stabilisation
tetralogy of fallot
- Comprises a large ventricular septal defect, an overriding aorta and a right ventricular outflow obstruction and right ventricular hypertrophy
left sided heart obstruction
- Coarctation of the aorta narrowing of aorta, takes blood from the ventricle of the heart to the rest of the body
- Hypoplastic left heart syndrome underdeveloped left ventricle, atrial septal anomalies and hypoplastic ascending aorta and coronary arteries with blood passing into the aorta through the patent ductus arteriosus – maintained with prostaglandin
- Tachypnoea, enlarged liver, decreased femoral pulses, decreased urine output, murmur
