简要总结
Patients admitted to the Neurosciences Intensive Care Unit (NSICU) are at particular risk of developing ICU-associated weakness and myopathy, given the unique risks of early mobilization in these patients, which include increased intracranial pressure, hemodynamic instability, vasospasm, decreased cerebral blood flow with resultant cerebral ischemia, and delirium. Interventions that could provide some of the benefits of early mobilization without these risks would be of great utility in the NSICU. A number of studies have demonstrated that electrical stimulation of the lower extremity muscles, generally the quadriceps, can retard disuse atrophy and loss of strength associated with medical ICU stays, and one study has shown reduced length of intubation and accelerated functional recovery. This pilot trial will evaluate the impact of electrical stimulation on patients in the NSICU, with a hypothesis that electrical stimulation treatments will reduce the length of hospital stay and intubation and improve functional recovery. In this trial, intubated patients admitted to the NSICU will have electrical stimulation applied to the quadriceps muscle groups on both lower extremities simultaneously for 45 minutes at a time for a total of 5 treatments each week, for up to 14 days or until ICU discharge, whichever comes first.
详细描述
The purpose of this pilot trial is to estimate the effect of electrical stimulation (e-stim) to the bilateral quadriceps on duration of intubation, ICU and hospital length of stay, and functional recovery in the NSICU in comparison to historical matched controls. The objectives of this initial pilot and feasibility study are to estimate the effect size to power a future full scale randomized controlled trial of this intervention and to optimize study logistics for a future full scale trial. The specific aims of the trial are:
Specific Aim 1 - Feasibility: Determine whether at least 4 of 5 planned treatments can be performed as described, and whether there is adequate patient population meeting inclusion criteria available for study
Specific Aim 2 - Efficacy: Evaluate efficacy of e-stim by comparing length of ICU stay (days from admission to "intermediate level of care" ordered in Epic) and duration of intubation (days) of subjects to that of historical controls.
Specific Aim 3 - Exploratory: Evaluate functional recovery (measured by modified Rankin Scale [mRS] and Extended Glasgow Outcome Scale [GOSE] at NSICU discharge) of subjects compared to that of historical controls.
Hypothesis: The investigators hypothesize that e-stim treatments will reduce the length of hospital stay and intubation and improve functional recovery.
