A double blind, randomized trial on augmentation of labour with a combination of intravenous propranolol and oxytocin versus oxytocin only.

Objective: To compare the combination of intravenous propranolol and oxytocin with oxytocin only in augmentation of labour.

Study Design: A prospective randomized double-blind study in an obstetric department of a large university hospital in Finland.
