Plain English Summary

Background and study aims
Nausea and vomiting are common symptoms during early pregnancy, occurring in about 70–85% of pregnancies. Some pregnant women experience excessive nausea and vomiting, known as hyperemesis gravidarum, which leads to dehydration and significant weight loss. Hospitalisation is typically needed to rehydrate patients through a drip and to control nausea and vomiting with medication. In hyperemesis gravidarum, nausea may be triggered by just the thought of food, and vomiting often follows drinking or eating. In women recently hospitalised for hyperemesis it is not known whether there is benefit to a short (12 hour) delay in eating and drinking to allow rehydration and medication to take effect before eating and drinking is restarted. On the other hand, continuing to feed at the same time as rehydration and medication may permit the quickest recovery path. The aim of this study is to find out which is the better approach.

Who can participate?
Pregnant women aged 18 or over with hyperemesis gravidarum

What does the study involve?
Participants are randomly allocated to one of two groups. One group is encouraged eat and drink as soon as possible after hospitalisation. The other group is told to delay eating and drinking (fast) for the first 12 hours after hospitalisation, then resume eating and drinking at their own pace. Both groups receive intravenous rehydration (a drip), thiamine (vitamin) supplementation and anti-emetic (anti- vomiting) medication as standard inpatient treatment for hyperemesis gravidarum. Frequency of vomiting, nausea, patient satisfaction and duration of hospitalisation are measured.

What are the possible benefits and risks of participating?
We do not foresee any major benefits or significant risks. It is not clear which intervention will prove to be superior and there is a distinct likelihood the interventions may produce similar outcomes.

Scientific titleDelayed compared with early oral intake in the initial manangement of hyperemesis gravidarum: a randomised trial
Study hypothesisAn initial 12-hour period of fasting (delayed oral intake) at hospitalisation for hyperemesis gravidarum to allow for hydration and anti-emetic medication to become effective compared to early feeding will result in less nausea and vomiting and higher patient satisfaction at 24 hours.
Ethics approval(s)University Malaya Medical Centre Medical Ethics Committee, 04/02/2016, approval no. 1206.12
ConditionHyperemesis gravidarum
InterventionParticipants are randomized to:
1. Delayed oral intake (fasting) for the first 12 hours after hospitalisation for hyperemesis gravidarum followed by resumption of taking fluids and solids orally at the participants own pace
2. Encouraged to take fluids and solids orally as soon as, as much as and as often as tolerated after hospitalisation for hyperemesis gravidarum

Both arms are to receive intravenous rehydration, oral thiamine supplementation and intravenous anti-emetic as standard inpatient treatment for hyperemesis gravidarum
Intervention typeBehavioural
Primary outcome measure1. Frequency of vomiting in the first 24 hours
2. Nausea score (using a Visual Numerical Rating Scale from 0 to 10) at enrollment, 8, 16 and 24 hours
3. Patient’s satisfaction score (using a Visual Numerical Rating Scale from 0 to 10) at 24 hours
Secondary outcome measures1. Duration of hospitalisation
2. Ketonuria at 24 hours
3. An 8-item symptoms questionnaire at 24 hours
4. Participant preference on feeding regimen in a future hospitalisation for hyperemesis gravidarum at 24 hours
5. Participant recommendation of their feeding regimen to a friend in the same circumstances at 24 hours
