Low-dose dopamine for women with severe pre-eclampsia.

BACKGROUND

Hypertensive disorders during pregnancy are important causes of maternal mortality and morbidity worldwide. The long-term outcome of surviving mothers will depend largely on whether intracranial haemorrhage or renal failure developed. Low-dose dopamine is used for the prevention and treatment of acute renal failure, but its role in the management of pregnant women with severe pre-eclampsia is unclear.

OBJECTIVES

To assess the effects of low-dose dopamine used for oliguria in severe pre-eclampsia on mothers and their children.

SEARCH STRATEGY: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (June 2006).

SELECTION CRITERIA: Randomised trials comparing low-dose dopamine (dosages not higher than 5 microgram/kg/minute) with either placebo or no dopamine in women with severe pre-eclampsia and acute renal failure, or who are considered to be at risk of acute renal failure.

DATA COLLECTION AND ANALYSIS: The two review authors assessed trial quality and data independently.

MAIN

RESULTS

Only one randomised placebo controlled trial of six hours' duration, including 40 postpartum women, was found. This study showed a significant increase in urinary output over six hours in women receiving dopamine. It is unclear if this was of any benefit to the women.

AUTHORS'

CONCLUSIONS

It is unclear whether low-dose dopamine therapy for pre-eclamptic women with oliguria is worthwhile. It should not be used other than in prospective trials.
