OBJECTIVE To assess the cost effectiveness of alternating pressure mattresses compared with alternating pressure overlays for the prevention of pressure ulcers in patients admitted to hospital. DESIGN Cost effectiveness analysis carried out alongside the pressure relieving support surfaces (PRESSURE) trial; a multicentre UK based pragmatic randomised controlled trial. SETTING 11 hospitals i...
BACKGROUND Adult mechanical ventilators have traditionally been pressure- or time-triggered. More recently, flow triggering has become available and some adult ventilators allow the choice between pressure or flow triggering. Prior studies have supported the superiority of flow triggering during continuous positive airway pressure, but few have compared pressure and flow triggering during press...
A comprehensive review is presented on current international trends regarding research and management of severe acute brain trauma. Controversial issues are thoroughly discussed and an attempt is made to clarify questionable aspects from pertinent publications in the international literature. A proposition is made to manage not only intracranial pressure and perfusion pressure, but also cerebra...
