Brief Summary

Advances in intensive care and mechanical ventilation (MV) in the past two decades have increased critically ill patient survival. However, some patients require prolonged MV (PMV) and are deconditioned due to respiratory insufficiency caused by underlying disease, adverse effects of medications, and prolonged immobilization. Patients in the intensive care unit (ICU) are often confined to their beds, which results in inactivity, immobility, and severe osteomyoarticular system dysfunction. Our hypothesis is that an early mobilization protocol improves muscle thickness (MT) of the quadriceps femoris, peripheral muscle strength, perceived functional status, gait speed, quality of life, duration of mechanical ventilation, ICU length of stay of the critically ill patient.

The purpose of this study is to evaluate the effects of implementation an early mobilization protocol in critically ill patients in the Intensive Care Unit of the University Hospital of Santa Maria.

Early Mobilization protocolEarly mobilization protocolEarly Mobilization protocol: Patients in the treatment group additionally received a progressive cycling exercise session 7 days a week, until the last day of ICU stay, using a bedside cycle ergometer (MOTOmed Letto 2, RECK-Technik GmbH \& Co. KG, Betzenweiler, Germany). Cycling exercise will be realized during 30 consecutive minutes, initially in continuos and passive (classified patients with RASS - 4) exercise, at a fixed pedaling rate of 20 cycles/min and after in actively (classified patients with RASS 0), with an exercise intensity of 3-5 on the Borg rate of perceived exertion scale.
Primary Outcome Measures
NameTimeMethod
Muscle thickness (MT) of the quadriceps femoris.Change from baseline at 14 day of ICU admission, an average of 1 month.

MT of the quadriceps femoris will be assessed by ultrasonography (baseline and 14 day).

Muscle thickness (MT) of the diaphragm.Change from baseline at 14 day of ICU admission, an average of 1 month.

MT of the diaphragm will be assessed by ultrasonography (baseline and 14 day).

Secondary Outcome Measures
NameTimeMethod
Gait speedStudy completion, an average of 2 months (hospital discharge)

Gait speed will be measured by the six-meter gait speed test (GST)

Quality of life following hospital dischargeThree months after hospital discharge SF36

Quality of life will be measured by a questionnaire 36-item Short Form Health Survey

MortalityPatients will be followed until three months after hospital discharge
Length of hospital stayPatients will be followed until hospital discharge, an expected 4 to 6 weeks
Rectus femoris cross-sectional areaChange from baseline at 14 day of ICU admission, an average of 1 month.

Rectus femoris cross-sectional area will be assessed by ultrasonography (baseline and 14 day).

Rectus femoris and vastus intermedius thickness.Change from baseline at 14 day of ICU admission, an average of 1 month.

Rectus femoris and vastus intermedius thickness will be assessed by ultrasonography (baseline and 14 day).

Peripheral muscle strength of the lower limbsStudy completion, an average of 2 months (hospital discharge)

Peripheral muscle strength of the lower limbs will be measured by 30 second chair stand test

Vastus intermedius, rectus femoris and diaphragm echo intensity.Change from baseline at 14 day of ICU admission, an average of 1 month.

Vastus intermedius, rectus femoris and diaphragm echo intensity will be assessed by ultrasonography (baseline and 14 day)

Muscle strengthFirst day of the patient was cooperative and responsive and at day 14 of ICU admission, an average of 1 month.

Muscle strength in arms and legs will be measured by the Medical Research Council (MRC) scale.

ICU length of stayPatients will be followed until ICU discharge, an expected 2 days to 3 weeks.
Weaning AccelerationPatients will be followed until ICU discharge, an expected 2 days to 3 weeks
Side effects of mobilization protocolDuring and 30 minutes after mobilization therapy during ICU stay, approximately 1 to 2 weeks.

Haemodynamic response to mobilization. Response in systolic and diastolic blood pressure. Response in heart rate. Response in peripheral oxygen saturation.
