Brief Summary:

Rationale : Electric muscle stimulation reduced critical-illness related weakness in patients with severe sepsis and septic shock. But optimal protocol of the stimulation in unknown.

Hypothesis: Focal muscle contraction may improved the muscle power and have systemic anti-inflammatory via cytokine secretion . The difference of electricity used in upper limb or lower limb stimulation may lead to different effect.

Study design: Stratified randomized parallel control study, comparing Biceps, Quadriceps electric muscle stimulation vs. non-stimulation group.

Participant: adult patients with severe sepsis and acute respiratory failure requiring mechanical ventilation.

Intervention: daily stimulation of bilateral Biceps or Quadriceps by programmed electric devices 32 minutes, 5 days/week


  1. Primary outcome: Ventilator-dependent days
  2. Secondary outcome: change of hand drip muscle power/interleukin-1b/interleukin-6/interleukin-8/TNF-alpha

Condition or disease Intervention/treatment Phase
Severe Sepsis Acute Respiratory Failure Muscle Hypotonia Inflammation Weakness Device: EMS Not Applicable

Detailed Description:

Background : Severe sepsis and septic shock remain top cause of admission to intensive care unit. Muscle weakness was found in 70-100% patients with severe sepsis and septic shock because of critical-illness induced polyneuropathy and myopathy. Previous study revealed electric muscle stimulation (EMS) could reduce such muscle weakness and mechanical ventilator-dependent days.

Hypothesis: different electricity may be needed for minimal contraction of upper or lower limb because of their muscle size. Induced muscle contraction may lead to myokine secretion and beneficial metabolic and anti-inflammatory effect. Stimulation on Quadriceps may be better than on Biceps.

Participant: adult(older than 20 years-old) patients with severe sepsis.septic shock and acute respiratory failure post mechanical ventilation.

Design: Stratified ( gender and age >50 years-old) Randomized parallel 3 arms study.

Intervention: Daily stimulation of Biceps of Quadriceps after third days in intensive care unit. Programmed electric stimulation device ( HELEX 573 model, strength aggressive. mode, 45-55Hz 32 minutes per day, voltage 30-70mA)

Primary Outcome Measures :
  1. ventilator-dependant days [ Time Frame: 21 days ]
    Patient days on mechanical ventilator ( Our National Health Insurance provide 21 days for acute intensive care at most)

Secondary Outcome Measures :
  1. Muscle strength improvement [ Time Frame: 21 days ]
    muscle power measurement by hand grip digital dynamometer every 2 days

Other Outcome Measures:
  1. Inflammatory cytokine change [ Time Frame: First 1 week. ]
    Serum interleukin(IL)-1B, IL-6, IL-8, IL-10, IL-15 and tumor necrosis factor(TNF)-alpha will be measured before/after first section of EMS, and after fifth EMS section.
