A known insulin-dependent diabetic parturient at 32 weeks' gestation was tr
eated with oral steroids for presumed exacerbation of asthma. This resulted
in maternal ketoacidosis and a non-reassuring fetal heart rate trace for w
hich caesarean section was considered. Cessation of steroids and aggressive
management of ketoacidosis resulted in improved maternal and fetal conditi
on without the need for emergency caesarean section. (C) 2001 Harcourt Publ
