Single case links maternal propranolol to neonatal complications; hypothesis-generating and leaves open causality in IHSS pregnancy.
A case is presented of a low birth weight infant born prematurely with depressed respiration, sinus bradycardia, and hypoglycemia associated with maternal propranolol therapy during pregnancy and up until labor and delivery. The need for caution in the casual use of propranolol during pregnancy in an asymptomatic patient with IHSS and the potential fetal complications are emphasized.
