Effect of Early Mobilization on Respiratory and Limb Muscle Strength and Functionality of Nonintubated Patients in Critical Care: A Feasibility Trial

الملخص EN

Purpose.

To assess the potential effectiveness or efficacy of early mobilization on respiratory and peripheral muscle strengths and functionality in nonintubated patients.

Methods.

For 40 nonintubated patients over 18 years of age with over 24-hour intensive care unit (ICU) stay allocated to a single intervention, an incremental mobilization protocol was initiated.

Maximal inspiratory and expiratory pressures (MIP and MEP), peripheral muscle strength (handgrip strength (HGS) and Medical Research Council scale (MRC-s)), and functionality (FIM, ICF-BMS, PFIT-s, and FSS-ICU scales) were evaluated at ICU admission and discharge.

Results.

All outcomes were significantly improved (pre vs.

post values): MIP (43.93 ± 21.95 vs.

54.12 ± 21.68 cmH2O; P<0.001), MEP (50.32 ± 28.65 vs.

60.30 ± 21.23; P=0.002), HGS (25.5 (9.58) vs.

27.5 (9.48); P=0.046), MRC-s (58.52 ± 2.84 vs.

59.47 ± 1.81; P=0.023), FIM (54.4 ± 22.79 vs.

69.48 ± 12.74), ICF-BMS (28.63 ± 16.19 vs.

14.03 ± 11.15), PFIT-s (9.55 ± 2.34 vs.

11.18 ± 1.32) (P<0.001), and FSS-ICU (28.7 ± 9.1 vs.

32.6 ± 5.0; P=0.001).

The ceiling effect at admission/discharge was in MRC-s (60/82.5%), FSS-ICU (50/70%), and FIM (35/62.5%).

The floor effect occurred at discharge in ICF-BMS (7.5/52.5%).

Conclusions.

The early mobilization protocol seemed effective at maintaining/increasing the respiratory muscle strength and functionality of nonintubated patients in critical care.

Ceiling effect was high for MRC-s, FSS-ICU, and FIM scales.
