Early rehabilitation relieves diaphragm dysfunction induced by prolonged mechanical ventilation: a randomised control...

Area of Science:

• Critical Care Medicine
• Pulmonology
• Rehabilitation Therapy

Background:

• Prolonged mechanical ventilation (MV) in intensive care units (ICUs) is associated with diaphragm dysfunction.
• Diaphragm dysfunction can impede ventilator weaning and prolong recovery.
• Early rehabilitation interventions are being explored to mitigate these effects.

Purpose of the Study:

• To investigate the therapeutic efficacy of early rehabilitation therapy in patients undergoing prolonged MV.
• To assess the impact of rehabilitation on diaphragm function and ventilator weaning parameters.

Main Methods:

• A prospective randomized controlled trial involving 80 patients on MV for >72 hours.
• Patients were randomized into a rehabilitation group (n=39) or a control group (n=41).
• Rehabilitation involved six levels of exercises; diaphragm function was assessed using ultrasound (US).

Main Results:

• Prolonged MV significantly decreased diaphragmatic excursion (DE) and diaphragm thickening fraction (DTF) in both groups.
• The rehabilitation group showed significantly higher DTF and a smaller decrease in DTF after 3 days of therapy.
• Ventilator and intubation durations were significantly shorter in the rehabilitation group compared to the control group.

Conclusions:

• Early rehabilitation is feasible and effective in ameliorating diaphragm dysfunction caused by prolonged MV.
• Rehabilitation facilitates ventilator weaning and extubation in critically ill patients.
• Diaphragm ultrasound (US) is recommended for monitoring mechanically ventilated patients.
