Brief summary
The study will investigate the effects of neuromuscular electrical stimulation (NMES) in critically ill patients. The objective of this study will be investigate the effects of neuromuscular electrical stimulation (NMES) in critically ill patients.
Detailed description
The study will investigate the effects of neuromuscular electrical stimulation (NMES) in critically ill patients. It will be a randomised crossover clinical trial. Thirty-one patients will enrolled. Patients will be selected, randomly, to the intervention Protocol (decubitus position with the limbs raised and NMES) and control (decubitus position with the limbs raised without NMES).The patients will be allocated in Group 1 (intervention and control) or group 2 (control and intervention) with a wash-out period of 4 to 6 hours between them. The main outcome will be metabolic data. Linear mixed model will be used for analysis of dependent variables and estimated values of the mean of the differences of each effect. The results of this study will allow better understanding of the metabolic effects of NMES in patients critically ill.
Interventions
This device produces a muscle contraction in response to a externally generated low-voltage electric impulse, which is conducted through electrodes placed on the skin over the muscle group to be stimulated.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change of Oxygen consumption (VO2),from baseline and interventions. | VO2 will be taken during the each intervention, it will be taken only the first day | Change of Oxygen consumption (VO2) will be evaluated by calorimetry |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change of Carbon dioxide production (VCO2) from baseline and interventions. | VCO2 will be taken during the each intervention, it will be taken only the first day | Change of Carbon dioxide production (VCO2) will be evaluated by calorimetry |
Other
| Measure | Time frame | Description |
|---|---|---|
| Change of Resting energy expenditure (REE) from baseline and interventions. | REE will be taken during the each intervention, it will be taken only the first day | Change of Resting energy expenditure (REE) will be evaluated by calorimetry |
