Programmed intermittent epidural bolus regimen vs continuous epidural infusion: a retrospective study of motor block and obstetric outcomes using the Robson's Ten Group Classification System.

Introduction of PIEB for maintenance of labour analgesia was associated with reduced incidence of motor block in our institution compared with CEI. Presenting results according to Robson's TGCS in future studies may allow better elucidation of the impact of neuraxial analgesia on maternal and obstetric outcomes.
