Safety and Performance of Muscle Activation for Critical Care Patients

Not Applicable
Terminated
Conditions
Critically-ill
Interventions
Procedure: Thermal-aided muscle activation
Registration Number
NCT01552616
Lead Sponsor
Niveus Medical, Inc.
Brief Summary

Critically-ill patients who have long stays in the hospital often face prolonged periods of bed rest. It is known that these patient develop profound weakness and debilitation. The effectiveness of existing muscle activation devices that could otherwise prevent the onset of debilitation in an immobilized patient has not been demonstrated widely in this cohort. It is hypothesized that using thermal methods to augment existing muscle activation techniques may demonstrate improved performance with no corresponding change in the safety profile.

Activation TreatmentThermal-aided muscle activation-
Primary Outcome Measures
NameTimeMethod
Muscle Activation EffectivenessDay of ICU Discharge, expected on average 5 days

Research team will assess whether or not visible or palpable muscle contractions can be activated in the target patient population.

Secondary Outcome Measures
NameTimeMethod
Muscle MassAt enrollment, at ICU discharge (expected average days), at hospital discharge (expected average 10 days)

Muscle mass will be measured at several time points during the patient stay.

Muscle StrengthAt enrollment, at ICU discharge (expected average days), at hospital discharge (expected average 10 days)

Muscle strength will be assessed using MRC scales at various time points throughout the study

Activities of Daily LivingAt hospital discharge (expected average 10 days)

The subject's proficiencies and independence in Activities of Daily Living will be assessed prior to hospital discharge.

Six Minute WalkAt time of first ambulation (expected average 7 days), at hospital discharge (expected average 10 days)

A 6 minute walk test administered per ATS guidelines will be undertaken by all patients prior to discharge. When possible at least 2 six minute walk tests will be administered.

Time to ambulationDuring timeframe when patient moves out of bed, expected on average 5 - 8 days into study

The time needed for a patient who had previously been subjected to bed rest to ambulate will be noted through chart review and nursing interviews.

Length of stayAt end of study, expected on average after 10 days

The subject's length of stay will be recorded from chart review.

Ventilator DependencyDuring active ventilation and weaning period, expected to last on average 4 - 7 days per patient

Chart review will be used to determine the number of ventilator days and the ventilator weaning time for each subject
