BACKGROUND: Early mobility within the ICU is associated with a number of positive outcomes including reductions in ICU and hospital length of stay and better functional recovery. The exact definition of 'early' mobility is still not defined, with the actual ability to mobilise limited by a number of perceived factors. The Sara Combilizer is a combined tilt table and stretcher chair, which allows passive transfer of patients out of bed. This study aimed to assess whether the introduction of the Sara Combilizer reduced time taken to first mobilise for patients mechanically ventilated for at least five days and at risk of ICU acquired weakness...

BACKGROUND: The promotion of early mobilization following critical illness is tempered by national reports of patient and institutional barriers to this approach. We carried out a survey to assess current knowledge, perceptions and practices of Canadian physicians and physiotherapists with respect to acquired weakness and early mobilization in adults in the intensive care unit (ICU). METHODS: We conducted a cross-sectional, self-administered postal survey among critical care physicians and physiotherapists in all 46 academic ICUs in Canada in 2011-2012...

Veno-venous extracorporeal membrane oxygenation (ECMO) has become a viable and increasingly utilized option for the treatment of refractory hypoxemia in severe acute respiratory distress syndrome (ARDS). However, options are limited for ARDS patients who fail to wean from ECMO. The high rates of infection, presence of extrapulmonary end organ damage, ICU-acquired weakness, and high short-term mortality associated with ARDS are all significant hurdles that make lung transplantation a difficult prospect to consider...

BACKGROUND: Treatment of critical illness on intensive-care-units (ICU) results often in persistent invasive endotracheal intubation which might delay rehabilitation and increases the risk of mortality. Recent longitudinal studies have described the recovery of critically ill people, but the detailed time course of decannulation in patients with chronic critical illness with ICU- acquired muscle weakness (ICUAW) is not well known. AIM: The aim of our study was therefore to describe the decannulation times and associated risk factors in patients who are chronic critically ill with ICU acquired weakness...

OBJECTIVE: In sepsis, the disease course of critically ill patients is often complicated by muscle failure leading to ICU-acquired weakness. The myokine transforming growth factor-β1 increases during inflammation and mediates muscle atrophy in vivo. We observed that the transforming growth factor-β1 inhibitor, secreted frizzled-related protein 2, was down-regulated in skeletal muscle of ICU-acquired weakness patients. We hypothesized that secreted frizzled-related protein 2 reduction enhances transforming growth factor-β1-mediated effects and investigated the interrelationship between transforming growth factor-β1 and secreted frizzled-related protein 2 in inflammation-induced atrophy...

Systemic inflammation and duration of immobilization are strong independent risk factors for the development of intensive care unit-acquired weakness (ICUAW). Activation of the pro-inflammatory transcription factor nuclear factor-κB (NF-κB) results in muscle wasting during disuse-induced skeletal muscle atrophy (ICU bed rest) and septic shock. In addition, NF-κB-mediated signaling plays a significant role in mechanical ventilation-induced diaphragmatic atrophy and contractile dysfunction. Older trials investigating high dose glucocorticoid treatment reported a lack of a sustained anti-inflammatory effects and an association with ICUAW...

OBJECTIVE: The relationship between neuromuscular blocking agents and neuromuscular dysfunction acquired in critical illness remains unclear. We examined the association between neuromuscular blocking agents and ICU-acquired weakness, critical illness polyneuropathy, and critical illness myopathy. DATA SOURCES: PubMed, EMBASE, Web of Science, Cochrane Central Register of Controlled Trials, Cumulative Index of Nursing and Allied Health Literature, and bibliographies of included studies were searched from database inception until September 24, 2015...

OBJECTIVES: Recovery from ICU-acquired muscle weakness extends beyond hospital stay. We hypothesized that immobilization, more than inflammation, plays a prominent role in the delayed recovery from critical illness. DESIGN: Prospective, randomized, controlled, experimental study. SETTING: Animal laboratory, university hospital. SUBJECTS: Male Sprague-Dawley rats. INTERVENTIONS: Animals were divided to have one hind limb immobilized (n = 129) or sham-immobilized (n = 129) on day -12...

BACKGROUND: Critical illness myopathy is an acquired skeletal muscle disorder with severe myosin loss and muscle weakness frequently seen in intensive care unit (ICU) patients. It is unknown if impaired excitation-contraction coupling contributes to the muscle weakness. METHODS: We used a unique ICU model where rats were deeply sedated, post-synaptically pharmacologically paralyzed, mechanically ventilated and closely monitored for up to ten days. Single intact fibers from the flexor digitorum brevis muscle were isolated and used to measure force and free myoplasmic [Ca(2+)] ([Ca(2+)]i) during tetanic contractions...

OBJECTIVES: To evaluate the internal consistency, validity, responsiveness, and minimal important difference of the Functional Status Score for the ICU, a physical function measure designed for the ICU. DESIGN: Clinimetric analysis. SETTINGS: Five international datasets from the United States, Australia, and Brazil. PATIENTS: Eight hundred nineteen ICU patients. INTERVENTION: None. MEASUREMENTS AND MAIN RESULTS: Clinimetric analyses were initially conducted separately for each data source and time point to examine generalizability of findings, with pooled analyses performed thereafter to increase power of analyses...

ICU acquired weakness (ICUAW) is a common complication of critical illness characterized by structural and functional impairment of skeletal muscle. The resulting physical impairment may persist for years after ICU discharge, with few patients regaining functional independence. Elucidating molecular mechanisms underscoring sustained ICUAW is crucial to understanding outcomes linked to different morbidity trajectories as well as for the development of novel therapies. Quadriceps muscle biopsies and functional measures of muscle strength and mass were obtained at 7 days and 6 months post-ICU discharge from a cohort of ICUAW patients...

Sarcopenia occurring as a primary consequence of aging and secondary due to certain medical problems including chronic disease, malnutrition and inactivity is a progressive generalized loss of skeletal muscle mass, strength and function. The prevalence of sarcopenia increases with aging (approximately 5-13 % in the sixth and seventh decades). However, data showing the prevalence and clinical outcomes of sarcopenia in intensive care units (ICUs) are limited. A similar condition to sarcopenia in the ICU, called ICU-acquired weakness (ICU-AW), has been reported more frequently...

Caring for critically ill patients receiving mechanical ventilation in the intensive care unit (ICU) is an immense challenge for clinicians. Interventions to maintain physiological stability and life itself can cause a number of adverse effects that have a marked impact on patients beyond the period of critical illness or injury. These ICU-acquired conditions include but are not limited to weakness, depression, and post-intensive care syndrome, all of which markedly affect patients' quality of life after they leave the unit...

BACKGROUND: Functional mitochondria in skeletal muscle of patients with protracted critical illness and intensive care unit-acquired weakness are depleted, but remaining mitochondria have increased functional capacities of respiratory complexes II and III. This can be an adaptation to relative abundancy of fatty acid over glucose caused by insulin resistance. We hypothesized that the capacity of muscle mitochondria to oxidize fatty acid is increased in protracted critical illness. METHODS: We assessed fatty acid oxidation (FAO) and mitochondrial functional indices in vitro by using extracellular flux analysis in cultured myotubes obtained by isolating and culturing satellite cells from vastus lateralis muscle biopsy samples from patients with ICU-acquired weakness (n = 6) and age-matched healthy controls (n = 7)...

BACKGROUND: Intensive care unit (ICU) and mechanical ventilation (MV) acquired limb muscle and diaphragm dysfunction may both be associated with longer length of stay and worse outcome. Whether they are two aspects of the same entity or whether they have a different prevalence and prognostic impact remains unclear. This study was designed to quantify the prevalence and coexistence of these two forms of ICU-acquired weakness and their impact on outcome. METHODS: In patients undergoing a first spontaneous breathing trial (SBT) after at least 24 h of MV, diaphragm dysfunction was evaluated using twitch tracheal pressure in response to bilateral anterior magnetic phrenic nerve stimulation (a pressure <11 cmH2O defined dysfunction) and ultrasonography (thickening fraction (TFdi) and excursion)...
