Prednisone
Most common etiology of CAP
Strep pneumonia
Most common cause of influenza pneumonia
Influenza A and B
Most frequent pneumonia complication
Premature rupture of membranes
Pneumonia complications in fetus
Low birth weight
Bacterial pneumonia management
Hospitalize pregnant women with pneumonia by Xray
Antibiotic therapy in bacterial pneumonia
Macrolide - initial monotherapy
Fluoroquinolone - severe cases
B-lactams (co-amox)
Management of influenza pneumonia
Supportive
Neuraminidase inhibitors to shorten course
Fetal response to maternal hypoxemia
Decrease cardiac output
Sign of a Potentially fatal asthma attack
Central cyanosis
