The Role of Ischaemia-reperfusion Injury in the Pathogenesis of Muscle Wasting After Thoracic Aortic Surgery (RIMMAS)
Observational Study Into the Effect on Muscle Wasting and Multiple Organ Function of Ischaemia-reperfusion Injury After Major Aortic Surgery
調査の概要
詳細な説明
Some patients who are critically ill develop a syndrome of muscle weakness called Intensive Care Unit Acquired Paresis. This syndrome involves the development of severe muscle wasting and weakness and affects all skeletal muscles including the muscles which help one breathe. Muscle wasting and weakness whilst critically ill cause prolongation of mechanical ventilation, longer stays on the ICU, reduced mobility and prolonged rehabilitation in survivors. It has also been shown to increase the risk of death on ICU, due to an inability to wean patients from mechanical ventilation. Most patients recover; however in some, the effects last for many years and patients may not recover fully.
Although there is some understanding of why this syndrome develops, the molecular processes underlying the muscle wasting are not well understood. From the current scientific evidence, the investigators have identified a group or family of proteins believed to be important in the development of this condition, the activity of which are regulated by disease processes thought to lead to Intensive Care Unit Acquired Paresis (e.g. infection, inflammation, oxidative stress, immobility).
This research aims to investigate the role of these proteins in human tissue from patients who are at risk of Intensive Care Unit Acquired paresis. Even patients who do not go on to develop the full syndrome, in the early stages of ICU care, show some signs of muscle changes and loss of strength.
