Muscle Changes in Critically Ill Children Following an Early Progressive Exercise in the Paediatric Intensive Care...

Area of Science:

• Pediatric Intensive Care
• Rehabilitation Medicine
• Pediatric Critical Care

Background:

• Critically ill children in the paediatric intensive care unit (PICU) often experience prolonged immobility.
• Immobilisation in the PICU can lead to negative physical health outcomes for children.

Purpose of the Study:

• To evaluate the effectiveness of an early progressive exercise (EPE) intervention for improving muscle weakness in PICU patients.
• To assess the safety and feasibility of implementing an EPE intervention in the PICU setting.

Main Methods:

• A single-centre, pre- and post-intervention study design was employed.
• The EPE intervention was initiated within 48-72 hours of PICU admission for children not requiring mechanical ventilation.
• Primary outcome measured was the 7-day change in right rectus femoris muscle cross-sectional area (RRMCSA).

Main Results:

• The EPE group showed a significantly smaller decrease in RRMCSA and right rectus femoris muscle thickness (RRMT) over 7 days compared to the pre-intervention group.
• Functional Status Score (FSS) was significantly lower (better) in the post-intervention group.
• A high completion rate (99.2%) of exercise sessions was observed with no reported adverse events.

Conclusions:

• Early progressive exercise (EPE) effectively slowed muscle atrophy in critically ill children without mechanical ventilatory support in the PICU.
• The EPE intervention demonstrated safety and feasibility, supporting its use in pediatric intensive care.
• Further research is recommended to confirm the long-term physical health benefits of early rehabilitation post-PICU discharge.
