BACKGROUND
Leg oedema from venous insufficiency is not dangerous but it can cause women symptoms such as pain, feelings of heaviness, night cramps and paraesthesiae. Leg oedema can be a sign of pre-eclampsia when associated with raised blood pressure or proteinuria.
OBJECTIVE
The objective of this review was to assess the effects of treatment to relieve the symptoms associated with varicosity in pregnancy and to reduce leg oedema.
METHODS
We searched the Cochrane Pregnancy and Childbirth Group trials register.
METHODS
Randomised trials of any form of treatment for varicosity or leg oedema in pregnancy.
METHODS
Trial quality was assessed and data were extracted independently by two reviewers.
RESULTS
Three trials of three different treatments were included. A total of 115 women were involved. In one trial, two thirds of women given rutoside capsules in the last three months of pregnancy noted an improvement in symptoms compared with only one third given placebo (odds ratio 0.30, 95% confidence interval 0.12 to 0.77). They had a decrease in ankle circumference at 36 weeks' gestation after eight weeks of treatment, while women given placebo had a small increase. In one trial, women with ankle oedema had a small non-significant reduction in lower leg volume when treated with external pneumatic intermittent compression for 30 minutes. Fifty minutes immersion in water at 32 degrees Celsius resulted in greater diuresis and fall in blood pressure than 50 minutes bedrest.
CONCLUSIONS
Rutosides appear to relieve symptoms of venous insufficiency in late pregnancy. However it is not known if the drug is safe in pregnancy. External pneumatic compression appears to reduce ankle swelling. Immersion in water for 50 minutes results in diuresis and fall in blood pressure. It is not known for how long these changes are sustained nor whether they are of any benefit.
