Musculoskeletal Ultrasound Study in Critical Care: Longitudinal Evaluation (MUSCLE)

Details and patient eligibility
About
Each year, 110,000 English/Welsh patients are admitted to Intensive Care Units (ICU). Many face prolonged disability as a result. Over two thirds have moderate-extreme limitation in their usual activity a year later, and one-third are severely affected, being unable to continue "most activities," or to live independently. Quite why known- but severe muscle wasting isn't may play an important role. We hope to find out, measuring the degree of wasting in patients, and seeking potential causes. We shall also address the mechanism of wasting, which may reflect an altered balance of activity in muscle growth pathways and those that break muscle down. We'll do this by collecting data, taking regular blood tests, scanning the leg muscles with an ultrasound machine, and analysing small muscle samples. In addition, we'll accurately and objectively measure how impaired these patients become, using specialist questionnaires, special monitoring equipment, simple walking tests and occasional special ('Cardio-Pulmonary') exercise tests. We'll try to see how badly activity is limited, and tease out whether muscle weakness plays a significant role in this. Finally, keeping muscles working (hard to do when unconscious/drowsy/bed-bound) may maintain muscle mass, so we'll see whether maintaining muscle activity using painless electrical stimulation will help.
