Large trial finds no benefit from restricting limb blood supply before heart surgery

Early small studies suggested that a period of restriction of blood supply to the arm just before cardiac surgery might confer some protection to the heart during surgery (please see ‘A review of restricting blood supply to a limb before heart surgery highlights the need for better evidence’). The NIHR funded this large, multi-centre trial ...

A review of restricting blood supply to a limb before heart surgery highlights the need for better evidence

This review of trials looked at a procedure that restricts blood supply to a limb just before heart surgery, which might prepare the heart for reduced blood flow during surgery. The technique was tested alongside the use of inhaled or injected anaesthetic. The review of 55 trials found the technique in combination with inhaled anaesthetic ...

Breathing training before major surgery may reduce lung complications afterwards

This review found that physiotherapist-led training in breathing before heart or major abdominal surgery was associated with a reduced risk of lung collapse or pneumonia after surgery. There was no evidence that it reduced the numbers of people ventilated for 48 hours or more, or the chance of death after the operation. Post-operative lung complications ...

The more active local authorities were in reducing access to alcohol, the greater the drop in admissions. Local authorities have two main powers that can be ...

Ultrasound guided nerve blocks are safe, effective and save time

This Cochrane review found that nerve blocks to provide local anaesthesia in the arms or legs of adults before a surgical procedure were safe and effective when guided by ultrasound compared to other guidance techniques. They were successful about nine times out of ten with ultrasound guidance, compared to about eight times out of ten ...

Vaginal progesterone suppositories did not boost the number of live births in women with recurrent miscarriage

A large trial found that vaginal progesterone suppositories taken in the first trimester of pregnancy were no better than a placebo at increasing live birth rates in women with previous unexplained recurring miscarriages. At 36 hospitals in the UK, and nine in the Netherlands, women under 40 used suppositories twice a day soon after a ...
