Artificial Induction of Labour in Full-term Singleton Pregnancy : Comparative Randomized Trial of Two Strategies

Rate of vaginal deliveries (both spontaneous or instrumentally assisted)

Number of spontaneous vaginal deliveries

Number of instrumentally assisted vaginal deliveries, including the reason for the assistance

Number of C-section including the reason for the C-section. The reasons for the C-section can be : a failure of dilatation at the first stage of the labour (between 0 and 10 cm), an absence of foetal descent at the second stage of labour, a foetal reason or a maternal reason)

Time elapsed between the beginning of the induction and the beginning of the labour

Cumulated number of spontaneous vaginal deliveries at 12 hours, 24 hours and 48 hours

Rate of labour induction failure is measure by the number of C-sections carried out due to a latency phase (0-6cm), which lasted more than 24 hours, together with the administration of oxytocin for at least 12 to 18 hours after the membranes artifically broke.

Number of secondary or tertiary use of Propess, Foley catheter of intra-veinous oxytocin

Number of peridural anaesthesia during labour

Uterine hyperstimulation is described as a number of contractions of 6 or more within 10 minutes, repeating at least twice). Foetal impact is defined as a slowing of the foetal heart rate.

Uterine hyperstimulation is described as a number of contractions of 6 or more within 10 minutes, repeating at least twice). Foetal impact is defined as a slowing of the foetal heart rate.

Uterine hypertonia is describes as a frequency of contractions every 2 minutes or less together with a slowing of the foetal heart rate.

Rate of post-partum haemorrhagia above 500 mL, above 1000 mL, transfusion level and number of packed red blood cells transfused

Number of patients with a uterine rupture

Number of patients with intra-uterine infections (body temperature above 38°C measured twice within 30 minutes, associated to 2 criteria within the followings: foetal tachycardia above 160 beats per minute, pain of the uterus or painful uterus contractions ou spontaneous labour induction, or purulent amniotic fluid.

Number of patients with post-partum infections (body temperature above 38°C with antibiotic treatment, urinary tract infections, bacteriological endometritis)

Number of fetuses with neonatal asphyxia

Number of newborn babies hospitalized in Neonatal intensive care unit

Number of proven bacteriological infections in newborn babies

Number of women who experienced metrorrhagias while putting in place the dilatation balloon or the vaginal pad (dinoprostone)

Measurement of Pain will be made using an Visual Analog Scale (VAS). The pain level will be linked to the inflation of the dilatation balloon and requiring the partial deflation of the balloon

Measurement will be made using a Visual Analog Scale (VAS) and will be recorded at different times of the dilatation balloon or the dinoprostone vaginal pad set up

Patient experience will be assessed using the W-DEQ (Wijma Delivery Expectancy/Experience Questionnaire)

The costs of the treatment and duration of the hospitalization will be measured
