Background and study aims
Hyperemesis gravidarum (HG) is severe nausea and vomiting occurring during pregnancy. It is fairly common, affecting about 2% of pregnant women, and hospital admission is needed for treatment. HG can lead to dehydration and starvation. The main treatment for HG is intravenous rehydration (fluids given directly into a vein through a drip). It is not known which fluid is best for the initial treatment of HG. Normal saline solution contains salt in the same concentration as blood. Dextrose-saline solution in addition to salt also contains dextrose (a form of sugar). Dextrose will provide calories at a time when the patient is not likely to be drinking or eating properly yet due to HG, which may allow a quicker recovery from starvation. The amount of glucose that we intend to administer over the 24-hour study period is probably about half of the carbohydrate intake in an average woman’s diet when she is eating normally. We are investigating whether the addition of dextrose to the intravenous solution used to treat women at the point of their hospitalisation for HG will result in a quicker recovery from starvation and make the patient feel better faster.
Who can take part?
Women aged 18 and over, hospitalised for the first time in their current pregnancy due to uncomplicated HG, and no more than 16 weeks pregnant.
What does the study involve?
Participants are randomly allocated to receive either normal saline solution or dextrose-saline solution.
What are the possible benefits and risks of participating?
In HG patients with severe thiamine deficiency (which can occur after prolonged starvation), dextrose infusion can cause a condition called Wernicke’s encephalopathy. To prevent this, before starting rehydration, all participants will receive a multivitamin intravenous injection containing thiamine.

| Scientific title | Dextrose saline versus saline solution infused for the initial rehydration of hyperemesis gravidarum: a randomized trial |
| Study acronym | DexSal Trial |
| Study objectives | Rehydration with the intravenous infusion of 5% dextrose-0.9% saline is hypothesised to result in a quicker resolution of ketonuria and generate a higher level of perceived well being compared to 0.9% saline. |
| Ethics approval(s) | University Malaya Medical Centre Ethics Committee, 22/09/2010, ref: 811.8 |
| Health condition(s) or problem(s) studied | Hyperemesis gravidarum |
| Intervention | Three litres of 5% dextrose-0.9% saline or three litres of 0.9% saline solution infused intravenously over 24 hours. |
| Intervention type | Drug |
| Pharmaceutical study type(s) | |
| Phase | Not Applicable |
| Drug / device / biological / vaccine name(s) | 5% dextrose, 0.9% saline |
| Primary outcome measure | 1. Resolution of ketonuria at 24 hours (using urine dipstick) 2. Well being at 24 hours using a Visual Numerical Rating scale (VNRS) |
| Secondary outcome measures | 1. Correction of hyponatraemia (≥ 136 mmol/l) 2. Correction of hypochloraemia (≥ 100 mmol/l) 3. Hyperglycaemia (any glucose level ≥ 8 mmol/l) 4. Nausea score at enrollment, 8. 16 and 24 hours (using VNRS) 5. Duration of intravenous (i.v.) rehydration during hospitalisation 6. Doses of of i.v. anti-emetic 7. Admission to discharge interval |
