The worldwide results published in the New England Journal of Medicine found the position of a patient’s head does not affect outcomes
A trial involving more than 11,000 patients suffering from stroke or brain attack has revealed that sitting up or lying flat after a stroke makes no difference to their recovery.
The research led by The George Institute for Global Health set out to discover if the bed position of people with the most common form of stroke, (acute ischaemic) reduced death or disability.
Some studies had indicated lying flat may improve recovery by increasing blood flow in the main arteries to the brain, but there were fears it also raised the risks of pneumonia.
The worldwide results published in the New England Journal of Medicine found the position of a patient’s head does not affect outcomes.
Lead investigator Professor Craig Anderson of The George Institute of Global Health, Sydney said, “Many stroke specialists believe that the way the body is positioned after stroke makes a difference to their patient’s recovery. But, there was really no conclusive evidence to back this up.“We know the first 24 hours of care post-stroke is crucial to recovery, so it was vital to find out if sitting up or lying down flat could make any difference.
National lead Principal Investigator Professor Jeyaraj D Pandian, Head of Neurology at Christian Medical College, Ludhiana stated, “Head position does not matter so much over and above good nursing care. It does not help with recovery, with mortality or how a patient feels. However, we also found there were no significant harms associated with either lying down flat or sitting up.” The study is the largest ever randomised nursing care trial and took place at 114 hospitals in nine countries (UK, Australia, China, Taiwan, India, Sri Lanka, Chile, Brazil, Colombia).
Professor Pandian added, “Patients were either assigned to lie flat with their face upwards or with their head raised to at least 30 degrees during the first 24 hours after being admitted to the hospital for a stroke. They were then assessed 90 days later. From India 499 patients were enrolled from six stroke centres (Christian Medical College, Ludhiana; PGIMER, Chandigarh; Dr Ramesh Super speciality Hospitals, Guntur; Narayana Hirudaya Mazumdhar Hospital Bangalore, SCTIMST Trivandrum and Baby Memorial Hospital, Calicut).
Professor Anderson said the results were very reassuring to lower to middle income countries, where lying flat is more commonly practiced due to the lack of motorised beds.
“What we found is that patients found lying flat somewhat uncomfortable, but it certainly didn’t make their condition any worse. Our findings suggest a review of current clinical practice guidelines is warranted,” Pandian added. The majority of patients who took part in the study had mild to moderate severity strokes, with an average age of 68 years.
This global trial was funded by National Health and Medical Research Council of Australia.
