Fifty pregnant patients with acquired and congenital heart disease between 38-41 weeks were randomised into elective induction and spontaneous labour groups only after bishop score was equal to or more than 6.It was concluded that induction of labour with oxytocin is a relatively safe procedure in women with low risk heart disease with NYHA class I and II. It resulted in a similar caesarean delivery rate and was not associated with more maternal and neonatal complications.

Arms Assigned Interventions
Active Comparator: induction of labour
drug- infusion of 30U oxytocin diluted in 500ml normal saline given at rate of 3mU/min and subsequently dose increased 3mU/min every 45 min
Drug: Oxytocin
Arm - Induction of labour
No Intervention: Spontaneous Labour
patients were allowed to go into spontaneous labour

Detailed Description:

Induction of labour was done with oxytocin. An infusion of 30U oxytocin diluted in 500ml normal saline was prepared and given through infusion pump at initial rate of 3mU/min. Subsequently dose was increased 3mU/min every 45 min till adequate uterine contractions were established.

Epidural analgesia was provided wherever feasible or Injection Morphine 2-5mg was given intravenously for pain relief.
