BACKGROUND: Critically ill patients frequently suffer muscle weakness whilst in critical care. Ultrasound can reliably track loss of muscle size, but also quantifies the arrangement of the muscle fascicles, known as the muscle architecture. We sought to measure both pennation angle and fascicle length, as well as tracking changes in muscle thickness in a population of critically ill patients. METHODS: On days 1, 5 and 10 after admission to critical care, muscle thickness was measured in ventilated critically ill patients using bedside ultrasound...

BACKGROUND: Critical illness is associated with muscle loss, weakness and poor recovery. The impact that illness and the ensuing metabolic response has on obese patients is not known. Objectives were to test if obese patients lose less muscle depth compared to non-obese patients; if a reduction in muscle depth was associated with reduced strength and recovery; and to assess the feasibility of these methods with a range of body mass index's (BMI). METHODS: A prospective observational pilot study of muscle depth in critically ill patients categorised by BMI was performed...

OBJECTIVE: To establish evidence-based guidelines for the use of bedside cardiac ultrasound, echocardiography, in the ICU and equivalent care sites. METHODS: Grading of Recommendations, Assessment, Development and Evaluation system was used to rank the "levels" of quality of evidence into high (A), moderate (B), or low (C) and to determine the "strength" of recommendations as either strong (strength class 1) or conditional/weak (strength class 2), thus generating six "grades" of recommendations (1A-1B-1C-2A-2B-2C)...

The majority of patients admitted to the ICU require mechanical ventilation as a part of their process of care. However, mechanical ventilation itself or the underlying disease can lead to dysfunction of the diaphragm, a condition that may contribute to the failure of weaning from mechanical ventilation. However, extended time on the ventilator increases health-care costs and greatly increases patient morbidity and mortality. Nevertheless, symptoms and signs of muscle disease in a bedridden (or bed rest-only) ICU patient are often difficult to assess because of concomitant confounding factors...

Over the last 10 years we have significantly reduced hospital mortality from sepsis and critical illness. However, the evidence reveals that over the same period we have tripled the number of patients being sent to rehabilitation settings. Further, given that as many as half of the deaths in the first year following ICU admission occur post ICU discharge, it is unclear how many of these patients ever returned home. For those who do survive, the latest data indicate that 50-70% of ICU "survivors" will suffer cognitive impairment and 60-80% of "survivors" will suffer functional impairment or ICU-acquired weakness (ICU-AW)...

OBJECTIVE: To compare sarcopenia and frailty for outcome prediction in surgical intensive care unit (SICU) patients. BACKGROUND: Frailty has been associated with adverse outcomes and describes a status of muscle weakness and decreased physiological reserve leading to increased vulnerability to stressors. However, frailty assessment depends on patient cooperation. Sarcopenia can be quantified by ultrasound and the predictive value of sarcopenia at SICU admission for adverse outcome has not been defined...

Bilateral diaphragmatic paralysis (BDP) manifests as respiratory muscle weakness, and its association with critical illness polyneuropathy (CIP) was rarely reported. Here, we present a patient with BDP related to CIP, who successfully avoided tracheostomy after diagnosis and management.A 71-year-old male presented with acute respiratory failure after sepsis adequately treated. Repeated intubation occurred because of carbon dioxide retention after each extubation. After eliminating possible factors, septic shock-induced respiratory muscle weakness was suspected...

RATIONALE: Diaphragm atrophy and dysfunction have been reported in humans during mechanical ventilation, but the prevalence, causes, and functional impact of changes in diaphragm thickness during routine mechanical ventilation for critically ill patients are unknown. OBJECTIVES: To describe the evolution of diaphragm thickness over time during mechanical ventilation, its impact on diaphragm function, and the influence of inspiratory effort on this phenomenon. METHODS: In three academic intensive care units, 107 patients were enrolled shortly after initiating ventilation along with 10 nonventilated intensive care unit patients (control subjects)...

Intensive care unit-acquired weakness (ICU-AW) causes significant morbidity and impairment in critically ill patients. Recent advances in neuromuscular ultrasound (NMUS) allow evaluation of neuromuscular pathology early in critical illness. Here we review application of ultrasound in ICU-AW. MEDLINE-indexed articles were searched for terms relevant to ultrasound and critical illness. Two reviewers evaluated the resulting abstracts (n = 218) and completed full-text review (n = 13). Twelve studies and 1 case report were included...

INTRODUCTION: Acute muscle wasting in the critically ill is common and associated with significant morbidity and mortality. Although some aetiological factors are recognised and muscle wasting can be detected early with ultrasound, it not possible currently to predict in advance of muscle loss those who will develop muscle wasting. The ability to stratify the risk of muscle wasting associated with critical illness prior to it becoming clinically apparent would provide the opportunity to predict prognosis more accurately and to intervene at an early stage...

BACKGROUND: Skeletal muscle wasting and weakness are common in patients with sepsis in the intensive care unit, although less is known about deficits in diaphragm and limb muscles when mechanical ventilation also is required. OBJECTIVE: The objective of this study was to concurrently investigate relative differences in both thickness and strength of respiratory and peripheral muscles during routine care. DESIGN: A prospective, cross-sectional study of 16 alert patients with sepsis and 16 people who were healthy (control group) was used...

The use of ultrasonography has become increasingly popular in the everyday management of critically ill patients. It has been demonstrated to be a safe and handy bedside tool that allows rapid hemodynamic assessment and visualization of the thoracic, abdominal and major vessels structures. More recently, M-mode ultrasonography has been used in the assessment of diaphragm kinetics. Ultrasounds provide a simple, non-invasive method of quantifying diaphragmatic movement in a variety of normal and pathological conditions...

OBJECTIVES: Acute muscle wasting in the critically ill is common and causes significant morbidity. In a novel human model of acute muscle wasting following cardiac surgery, known or potential circulating modulators of muscle mass--insulin-like growth factor-1, myostatin, and growth and differentiation factor-15--were measured over a week. It was hypothesized that patients who developed acute muscle wasting would show distinct patterns of change in these mediators. DESIGN: A prospective longitudinal observational study of high-risk elective cardiac surgical patients identifying, by ultrasound, those developing muscle wasting...

COMMENT
Robert D Stevens, Nicholas Hart, Bernard de Jonghe, Tarek Sharshar
Muscle weakness is prevalent in critically ill patients and can have a dramatic effect on short- and long-term outcomes, yet there are currently no interventions with proven efficacy in preventing or treating this complication. In a new randomized trial, researchers found that serial electrical muscle stimulation significantly mitigated ultrasound-defined muscle atrophy, and the treatment was not linked to adverse effects. Although preliminary, these results, together with other recent studies, indicate a paradigm shift to a proactive approach in managing neuromuscular complications in the ICU...
