Outcome Measures

Primary Outcomes (3)

  • Caesarean Delivery

    Number of Caesarean deliveries in the prediction group

    24 months

  • Acceptability of Intrapartum Ultrasound

    Acceptability of transabdominal and transperineal ultrasound to pregnant and labouring women. Use of modified W-DEQ questionnaires pre and post assessment. We recorded the number of women who completed both questionnaires.

    24 months

  • Feasibility of Ultrasound Labour Parameters

    The outcome was the number of women who had all labour parameters measured by ultrasound.

    24 months

Study Arms (3)

Acceptability

To assess acceptability of intervention. Some patients from this group also participated in the other groups.

Feasibility

Is it possible for ultrasound to measure labour parameters, where vaginal examinations are best avoided e.g. vaginismus or contraindicated (PPROM) with controls. Some patients from this group also participated in the other groups.

Predictive Model

Nulliparous term labouring women with cephalic presentation. Some patients from this group also participated in the other groups.
