Early Assessment of Quadriceps Muscle Recovery by Dynamometry and 3D Ultrasound in Intensive Care Patients Under Invasive Mechanical Ventilation

Официальное название

Early Assessment of Quadriceps Muscle Recovery by Dynamometry and 3D Ultrasound in Intensive Care Patients Under Invasive Mechanical Ventilation: A Monocentric and Prospective Study.

Обзор

Patients in intensive care often develop acquired muscle weakness (ICUAW or Intensive Care Unit Acquired Weakness) due to immobilization and muscle atrophy. Early mobilization can help reduce weakness and improve functional recovery, but practices vary. Muscle strength assessment, particularly using the MRC (Medical Research Council) score, is crucial, though it has precision limitations. Additional methods, such as manual dynamometry and functional scales, are needed to better track muscle recovery. The quadriceps, important for function, requires early evaluation, but there is a lack of specific data in intensive care to predict medium-term functional recovery.

Вмешательства

• Другое Early assessment of quadriceps muscle strength
  Patients will undergo non-invasive assessment of quadriceps muscle strength using manual dynamometry and 3D ultrasound. These assessments will be conducted regularly during their ICU stay to evaluate early recovery. The intervention is part of routine patient care and does not involve additional treatments or procedures.
