Case 1
Management of symptomatic pneumothorax:
Chest tube insertion Needle aspiration
Case 2
Unremarkable pregnancy 38 weeks’ gestation Elective Caesarian Section Presented respiratory distress
Focused respiratory history
Intrapartum
fetal distress during labour and delivery presence of meconium stained liquor duration of rupture of membranes evidence of chorioamnionitis (maternal fever) nature of labour and route of delivery medications administration of intrapartum antibiotics for
evidence of central cyanosis respiratory support vital signs: RR, HR, T, BP, SpO2
Physical examination
Examination
Auscultation of breath sounds presence of grunting, inspiratory stridor,
at 30 minutes

Case 1 post surfactant
Case 1
Ventilation setting unchanged Baby deteriorated rapidly, increase
oxygen concentration from 40% to 100%, mottled, heart rate is 188 bpm, air entry on left side decreased
Lack of surfactant, resulting in progressive collapse of the alveoli
Primarily a disease of preterm babies; its incidence increases with decreasing gestational age.
