Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A co-design, consensus-based activity was undertaken to develop the intervention arm of the study. This was developed in following evidence synthesis and in collaboration with representatives from obstetrics, anaesthetics, midwifery, neonatalology, lactation consultants, consumers and dietitians.

Women randomised to the intervention group will receive:
1. A brief (5-10 minutes) educational discussion (1-7 days prior to induction of labour) with the research midwife on optimising hydration during labour through oral intake. This discussion centres on advice on what, how much and when to eat and drink during labour.
2. No routine intravenous therapy administered as 'maintenance hydration' during labour
3. Intravenous boluses administered at clinician discretion (Hartmanns or Normal Saline 250-500 ml)

Midwives will be administering and monitoring all fluids and foods ingested. This will be documented on a Study specific Fluid Balance Chart, with all input and output measured and recorded.

Education will be provided face to face (twice weekly for 6 weeks) by a member of the research team in addition to a 10-minute recorded video which explains the study and intervention. This will be distributed to all midwifery and obstetrics staff working in Birthing suites within the study site. An information pack will also contain relevant documentation and will be held within the Birthing Suites. A log of all staff that have attended the education will be kept.

Treatment: Other
Comparator / control treatment
Standard Care, which involves:
1. No specific advice on what to eat and drink in labour (other than what is generally available)
2. Intravenous therapy of Hartmanns or Normal Saline @ 125ml/hr from commencement of oxytocin infusion for induction of labour, until birth of baby, as a maintenance fluid.
3. Intravenous boluses administered at clinician discretion as per usual care (Normal Saline or Hartmanns 250-500ml).
3. Unrestricted, ad hoc oral intake

Statistical methods / analysis
Feasibility outcomes will be reported descriptively and assessed in terms of the implications for a fully powered study. Baseline variables and secondary outcomes will be used to calculate estimates of effects, rather than inferential analysis, as this study is not powered to detect this. A costing analysis, incorporating length of stay information, will be undertaken to inform the development of an economic evaluation in a future trial.

Summary
Brief summary
This is a two-part study which involves two aims:
1. To develop a consumer- and evidence-informed maternal intrapartum hydration assessment and management intervention protocol for nulliparous women undergoing induction of labour which maintains maternal euvolaemia during parturition.
2. To evaluate the feasibility of undertaking a randomised control trial of the intervention developed in stage one with nulliparous women undergoing induction of labour within the RBWH.
