Too little evidence from trials to show whether hospital bed rest for pregnant women has a beneficial effect on the unborn baby's growth. An unborn baby receiving too few nutrients can grow more slowly than expected in the womb (impaired fetal growth). Bed rest is sometimes suggested to mothers of these babies with the view that less maternal physical ...

Too little evidence to show whether the unborn baby's growth improves when pregnant women take calcium channel blockers, and more research is needed. Calcium channel blocker drugs relax muscles and lower blood pressure by reducing the intake of calcium into some cells. It has been thought that these drugs may improve the growth of an unborn baby who ...

Anticoagulants are beneficial and safe for preventing a second stroke in people with nonrheumatic atrial fibrillation and recent cerebral ischaemia. Nonrheumatic atrial fibrillation (NRAF) is a heart rhythm disorder commonly found in patients who have had a stroke. Patients with NRAF have an irregular heart beat and this can cause the formation of a ...

Anticoagulants are more effective than antiplatelet drugs to prevent a second stroke in people with atrial fibrillation. Nonrheumatic atrial fibrillation (NRAF) is a heart rhythm disorder commonly found in patients who have had a stroke. Patients with NRAF have an irregular heart beat. This can cause the formation of a blood clot in the left atrium ...

There is not enough evidence to show if glycerol can reduce the disabling effects of brain swelling due to acute stroke. Brain swelling (or oedema) is a major cause of early death and long-term disability after stroke (a sudden catastrophe in the brain either because an artery to the brain blocks, or because an artery in or on the brain ruptures and ...

No evidence to show whether blood flow through the placenta is improved in pregnant women who have transcutaneous electrical nerve stimulation (TENS) therapy for suspected placental insufficiency. Babies who do not get enough nutrients and oxygen from their mothers may compensate this situation with some changes in the blood vessels which may lead to ...
