Clinical Trial Summary

The study will investigate the effects of neuromuscular electrical stimulation (NMES) in patients with septic shock. The objective of this study will be investigate the effects of neuromuscular electrical stimulation (NMES) in patients with septic shock.

Description:

The study will investigate the effects of neuromuscular electrical stimulation (NMES) in patients with septic shock. It will be a randomised crossover clinical trial. Thirty-one patients will enrolled.The study will be divided in two phases, the first will be held in the first 72 hours of septic shock and the second after three days of first assessment. Patients will be selected, randomly, to the intervention Protocol (NMES) and control (positioning). After this procedure the patients will be allocated in Group 1 (NMES and control) or group 2 (control and NMES), with a wash-out period of 4 to 6 hours in between . The main outcome will be the study of mobilization of endothelial progenitor cells (EPCs). The secondary outcome will be the metabolic and hemodynamic 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 effects of NMES in patients with septic shock.

Eligibility

Inclusion Criteria:The patients admitted to the intensive care unit will be considered

• they present in the first 72 hours the diagnosis of septic shock according to the international consensus definition of septic shock, and
• stable hemodynamics through fluid resuscitation, and
• vasoactive drugs and mechanical ventilation. Exclusion Criteria:The exclusion criteria will be patients aged less than 18 years and greater than 65 years, pregnant women, brain death, neuromuscular diseases, use of pre-existing neuromuscular blocker in the last 24 hours, prior to the study protocol.
• Contraindications for the use of NMES: fractures, burns and skin lesions, systemic vascular impairment diseases such as systemic lupus erythematosus, thromboembolic disease, deep vein thrombosis (which was not therapeutically anticoagulated for a time greater than 36 hours), lower limb amputations, cardiac pacemaker, thrombocytopenia less than 20,000/mm3, BMI greater than 35 kg/m2, important lower extremity oedema, agitation and/or signs of pain during the electrical stimulation.
• Contraindications to begin or continue NMES procedure: Mean arterial blood pressure less than 65 mmHg, use of vasopressor >50% of the maximum dose (dopamine >12.5 µg/kg per minute; vasopressin >0.02U/min and norepinephrine >1 µg/kg per minute), heart rate <50 or >140 bpm, arrhythmias with hemodynamic consequences, myocardial ischemia, temperature <34 or >39oC, intracranial pressure >20 cmH2O, decrease in 10% of SpO2 baseline value or <88% for more than one minute.

Intervention

Device:
• Neuromuscular Electrical Stimulation
The patient will be positioned on a headboard at 30° in the decubitus position with the limbs raised to 20°. The location of the electrical current will be cleared with trichotomy when necessary. Adhesive electrodes 90 x 50 mm will be positioned in the gastrocnemius. The stimulator device will be the Neurodyn II (Ibramed, Sao Paulo, Brazil) to provide symmetrical biphasic pulses of 50 Hz, 250 µsec pulse duration, 2 seconds on (1 second of time of rise and 1 second of time of decay), and 5 seconds of rest during 30 minutes at an intensity capable of generating visible contractions and articular motion.

Other:
• Decubitus Position with the limbs raised to 20º
The patient position will be the same used for intervention protocol (headboard to 30°, decubitus position with the limbs raised to 20°) for 30 minutes, without NMES.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Change of hemodynamic and respiratory variables	It will be measured heart rate, blood pressure, oxygen saturation and breathing frequency.	It will be taken at the baseline and at the end of the each intervention.The data will be collected in two phases, the first will be held in the first 72 hours of septic shock and the second after three days of first assessment.
Other	Change of Cirtometry	Measurements of the circumference of the gastrocnemius muscle.	Patients will be measured at the first, the third and the seventh day
Primary	Change of counts of Endothelial Progenitor Cells (EPCs)	Change of counts of mobilization of endothelial progenitor cells will be quantified by cytometry markers:+/CD133+/CD45-, CD34+/CD133+/CD45-/VEDFR2 e CD45-/VEGFR2+.	It will be taken at the baseline and at the end of the each intervention.The data will be collected in two phases, the first will be held in the first 72 hours of septic shock and the second after three days of first assessment.
Secondary	Change of Oxygen consumption (VO2), Carbon dioxide production (VCO2) and Resting energy expenditure (REE).	Indirect calorimetry is a noninvasive method that analyzes the amount of heat generated. by the whole body according to the substrate utilization. The data provided by calorimetry are: Resting Energy Expenditure (REE) which is calculated from the amount of oxygen consumed (VO2) and carbon dioxide produced (VCO2) through the respiratory gases.	It will be taken at the baseline and at the end of the each intervention.The data will be collected in two phases, the first will be held in the first 72 hours of septic shock and the second after three days of first assessment.
