Antepartum pneumonia in pregnancy.

Thirty-nine patients satisfying criteria for antepartum pneumonia in pregnancy were retrospectively reviewed. Twenty-one patients had culture-proved bacterial pneumonias. Streptococcus pneumoniae was the most common organism isolated (13/39). Significant anemia (hemoglobin less than or equal to 10 gm) was present in 49% of patients (19/37) on admission. In the patients presenting in the second and third trimesters (25 to 36 weeks) of pregnancy, 85% (11/13) were delivered at term. The perinatal mortality rate for the entire group was 40/1,000. There were no maternal deaths.
