Abstract
INTRODUCTION Survivors of critical illness often experience significant morbidities, including muscle weakness and impairments in physical functioning. This muscle weakness is associated with longer duration mechanical ventilation, greater hospital costs and increased postdischarge impairments in physical function, quality of life and survival. Compared with standard of care, the benefits of greater protein intake combined with structured exercise started early after the onset of critical illness remain uncertain. However, the combination of protein supplementation and exercise in other populations has demonstrated positive effects on strength and function. In the present study, we will evaluate the effects of a combination of early implementation of intravenous amino acid supplementation and in-bed cycle ergometry exercise versus a 'usual care' control group in patients with acute respiratory failure requiring mechanical ventilation in an intensive care unit (ICU). METHODS AND ANALYSIS In this multicentre, assessor-blinded, randomised controlled trial, we will randomise 142 patients in a 1:1 ratio to usual care (which commonly consists of minimal exercise and under-achievement of guideline-recommended caloric and protein intake goals) versus a combined intravenous amino acid supplementation and in-bed cycle ergometery exercise intervention. We hypothesise that this novel combined intervention will (1) improve physical functioning at hospital discharge; (2) reduce muscle wasting with improved amino acid metabolism and protein synthesis in-hospital and (3) improve patient-reported outcomes and healthcare resource utilisation at 6 months after enrolment. Key cointerventions will be standardised. In-hospital outcome assessments will be conducted at baseline, ICU discharge and hospital discharge. An intent-to-treat analysis will be used to analyse all data with additional per-protocol analyses. ETHICS AND DISSEMINATION The trial received ethics approval at each institution and enrolment has begun. These results will inform both clinical practice and future research in the area. We plan to disseminate trial results in peer-reviewed journals, at national and international conferences, and via nutritional and rehabilitation-focused electronic education and knowledge translation platforms.

Trials 2019; 20:456. [PMID: 31340849 PMCID: PMC6657179 DOI: 10.1186/s13063-019-3547-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2019] [Accepted: 06/29/2019] [Indexed: 01/09/2023] Open
Abstract
BACKGROUND Forty per cent of critically ill patients are affected by intensive care unit-acquired weakness (ICU-AW), to which skeletal muscle wasting makes a substantial contribution. This can impair outcomes in hospital, and can cause long-term physical disability after hospital discharge. No effective mitigating strategies have yet been identified. Application of a repetitive vascular occlusion stimulus (RVOS) a limb pressure cuff inducing brief repeated cycles of ischaemia and reperfusion, can limit disuse muscle atrophy in both healthy controls and bed-bound patients recovering from knee surgery. We wish to determine whether RVOS might be effective in mitigating against muscle wasting in the ICU. Given that RVOS can also improve vascular function in healthy controls, we also wish to assess such effects in the critically ill. We here describe a pilot study to assess whether RVOS application is safe, tolerable, feasible and acceptable for ICU patients. METHODS This is a randomised interventional feasibility trial. Thirty-two ventilated adult ICU patients with multiorgan failure will be recruited within 48 h of admission and randomised to either the intervention arm or the control arm. Intervention participants will receive RVOS twice daily (except only once on day 1) for up to 10 days or until ICU discharge. Serious adverse events and tolerability (pain score) will be recorded; feasibility of trial procedures will be assessed against pre-specified criteria and acceptability by semi-structured interview. Together with vascular function, muscle mass and quality will be assessed using ultrasound and measures of physical function at baseline, on days 6 and 11 of study enrolment, and at ICU and hospital discharge. Blood and urine biomarkers of muscle metabolism, vascular function, inflammation and DNA damage/repair mechanism will also be analysed. The Health questionnaire will be completed 3 months after hospital discharge. DISCUSSION If this study demonstrates feasibility, the derived data will be used to inform the design (and sample size) of an appropriately-powered prospective trial to clarify whether RVOS can help preserve muscle mass/improve vascular function in critically ill patients.

[PMID: 31219229 DOI: 10.1111/nicc.12455] [Citation(s) in RCA: 82] [Impact Index Per Article: 16.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2018] [Revised: 05/07/2019] [Accepted: 05/20/2019] [Indexed: 12/12/2022]
Abstract
BACKGROUND The aim of this meta-analysis was to assess if early mobilization and rehabilitation in the intensive care unit (ICU) could reduce ICU-acquired weakness (ICU-AW), improve functional recovery, improve muscle strength, shorten the length of ICU and hospital stays, and reduce the mortality rate. METHODS A comprehensive literature search in PubMed, Embase, Web of Science, SinoMed (Chinese BioMedical Literature Service System, China), and National Knowledge Infrastructure, China (CNKI) was performed. Results were expressed as a risk ratio (RR) with 95% confidence intervals (95% CIs) or weight mean difference (WMD) with 95% CIs. Pooled estimates were calculated using a fixed-effects or random-effects model according to the heterogeneity among studies. RESULTS Fifteen randomized controlled trials involving a total of 1941 patients were included in this meta-analysis. Pooled estimates suggested that early mobilization significantly reduced the incidence of ICU-AW (RR = 0.49, 95% CI: 0.26, 0.91; P = .025), shortened the length of ICU (WMD = -1.82 days, 95% CI: -2.88, -0.76; P = .001) and hospital (WMD = -3.90 days, 95% CI: -5.94, -1.85; P < .001) stays, and improved the Medical Research Council score (WMD = 4.47, 95% CI: 1.43, 7.52; P = .004) and Barthel Index score at hospital discharge (WMD = 21.44, 95% CI: 10.97, 31.91; P < .001). Moreover, early mobilization also decreased complications such as deep vein thrombosis (RR = 0.16, 95% CI: 0.04, 0.59; P = .006), ventilator-associated pneumonia (RR = 0.26, 95% CI: 0.11, 0.63; P = .003), and pressure sores (RR = 0.14, 95% CI: 0.04, 0.44; P = .001). However, early mobilization did not reduce the ICU mortality rate (RR = 1.31, 95% CI: 0.97, 1.76; P = .074), improve the handgrip strength (WMD = 4.03 kg, 95% CI: -0.68, 8.74; P = .094), and shorten the duration of mechanical ventilation (WMD = 0.20 days, 95% CI: -0.10, 0.50; P = .194). CONCLUSION This study indicated that early mobilization was effective in preventing the occurrence of ICU-AW, shortening the length of ICU and hospital stay, and improving the functional mobility. However, it had no effect on the ICU mortality rate and ventilator-free days. RELEVANCE TO CLINICAL PRACTICE ICU-AW is a common neuromuscular complication of critical illness, and it is predictive of adverse outcomes. Early mobilization of critically ill patients is a candidate intervention to reduce the incidence and severity of ICU-AW. Some clinical studies have demonstrated this, whereas others found opposite results. The aim of our study is to assess if early mobilization and rehabilitation in the ICU could reduce the ICU-AW, improve functional recovery, improve muscle strength, shorten length of ICU and hospital stay, and reduce the mortality rate.

Effects of neuromuscular electrical stimulation in critically ill patients: A systematic review and meta-analysis of randomised controlled trials. Aust Crit Care 2019; 33:203-210. [PMID: 31160215 DOI: 10.1016/j.aucc.2019.04.003] [Citation(s) in RCA: 31] [Impact Index Per Article: 6.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2019] [Revised: 03/29/2019] [Accepted: 04/07/2019] [Indexed: 11/20/2022] Open
Abstract
OBJECTIVES We performed a systematic review and meta-analysis to examine the effect of neuromuscular electrical stimulation (NES) on prevention of critical care myopathy and its effect on various clinical outcomes in the intensive care unit (ICU). REVIEW METHODS USED This study involved systematic review and meta-analysis of randomised controlled trials (RCTs) comparing NES (applied to different muscle groups combined with usual care) and usual care (passive and active exercises along with early mobilisation and rehabilitation). Included studies enrolled adult patients managed in the ICU for medical or surgical diseases who were or were not mechanically ventilated. The primary outcome was global muscle strength measured by the Medical Research Council grading system. Secondary outcomes included ICU mortality, duration of mechanical ventilation (MV), and ICU length of stay. Risk ratio for dichotomous data and mean difference (MD) for continuous data with their corresponding 95% confidence interval (CI) were calculated. DATA SOURCE A search in major electronic databases, including PubMed, Cochrane Library, and Embase, from inception to November 2018 was carried out. RESULTS Six RCTs were included, representing 718 patients. The mean age 60 ± 15.3 years, and 60.6% were male. There was no significant difference between NES and usual care on global muscle strength measured by Medical Research Council grading system (MD: 0.45; 95% CI: -2.89 to 3.80; p = 0.79), ICU mortality (risk ratio: 1.30; 95% CI: 0.95-1.78; p = 0.10), duration of MV (days) (MD: -2.07; 95% CI: -5.06 to 0.92; p = 0.18), or ICU length of stay (days) (MD: -3.06; 95% CI: -9.79 to 3.68; p = 0.37) in comparison with the usual therapy alone in critically ill patients. CONCLUSION NES combined with usual care was not associated with significant differences in global muscle strength, ICU mortality, duration of MV, or ICU length of stay in comparison with usual care alone in critically ill patients. Further RCTs are needed to determine patients with maximum benefit and to examine NES safety and efficacy.

Abstract
Intensive care unit-acquired weakness (ICU-AW) is the most common neuromuscular impairment in critically ill patients. We discuss critical aspects of ICU-AW that have not been completely defined or that are still under discussion. Critical illness polyneuropathy, myopathy, and muscle atrophy contribute in various proportions to ICU-AW. Diagnosis of ICU-AW is clinical and is based on Medical Research Council sum score and handgrip dynamometry for limb weakness and recognition of a patient's ventilator dependency or difficult weaning from artificial ventilation for diaphragmatic weakness (DW). ICU-AW can be caused by a critical illness polyneuropathy, a critical illness myopathy, or muscle disuse atrophy, alone or in combination. Its diagnosis requires both clinical assessment of muscle strength and complete electrophysiological evaluation of peripheral nerves and muscles. The peroneal nerve test (PENT) is a quick simplified electrophysiological test with high sensitivity and good specificity that can be used instead of complete electrophysiological evaluation as a screening test in non-cooperative patients. DW, assessed by bilateral phrenic nerve magnetic stimulation or diaphragm ultrasound, can be an isolated event without concurrent limb muscle involvement. Therefore, it remains uncertain whether DW and limb weakness are different manifestations of the same syndrome or are two distinct entities. Delirium is often associated with ICU-AW but a clear correlation between these two entities requires further studies. Artificial nutrition may have an impact on ICU-AW, but no study has assessed the impact of nutrition on ICU-AW as the primary outcome. Early mobilization improves activity limitation at hospital discharge if it is started early in the ICU, but beneficial long-term effects are not established. Determinants of ICU-AW can be many and can interact with each other. Therefore, future studies assessing early mobilization should consider a holistic patient approach with consideration of all components that may lead to muscle weakness.

Abstract
The 2018 Paris Intensive Care symposium entitled "Update in Neurocritical Care" was organized in Paris, June 21-22, 2018, under the auspices of the French Intensive Care Society. This 2-day post-graduate educational symposium comprised several chapters, aiming first to provide all-board intensivists with current standards for the clinical assessment of altered consciousness states (including coma and delirium) and peripheral nervous system in critically ill patients, monitoring of brain function (specifically, electro-encephalography) and best practices for sedation-analgesia-delirium management. An update on the treatment of specific severe brain pathologies-including ischaemic/haemorrhagic stroke, cerebral venous thrombosis, hypoxic-ischaemic brain injury, immune-mediated and infectious encephalitis and refractory status epilepticus-was also provided. Finally, we discuss how to approach some difficult decisions, namely the role of decompressive craniectomy and prognostication models in patients with head injury. For each chapter, the scope of the present review was to provide important issues and key messages, provide most recent and relevant literature in the field, and briefly describe new developments in the field.

Abstract
PURPOSE OF REVIEW The intended purpose of nutritional and exercise interventions during ICU stay is often to limit the muscle loss associated with critical illness. Unfortunately, direct measurements of muscle protein turnover or potential surrogates have often been neglected in clinical trials. RECENT FINDINGS We discuss the potential advantages and drawbacks of common outcome measures for assessing changes in muscle structure and function over time, and how temporal changes in patient physiology require consideration. There is an increasing awareness of emphasizing functional outcomes in recent clinical trials. We here summarize the latest research on therapies attempting to limit muscle loss in ICU patients, with a focus on muscle protein metabolism. No recent or older studies show any effect of nutritional interventions on muscle protein gain, although some smaller studies show a promising positive effect on muscle thickness and function. Some studies show a positive effect of increased physical activity in the ICU on muscle mass and function but heterogeneity of the interventions and outcome measures make any general conclusions impossible. SUMMARY Several knowledge gaps remain regarding the importance of muscle protein regulation as a driver of improved physical function following ICU discharge. In our opinion, physiological investigations are needed to guide the design and interpretation of future clinical trials.

Abstract
Some patients admitted to the intensive care unit (ICU) because of an acute illness, complicated surgery, or multiple traumas develop muscle weakness affecting the limbs and respiratory muscles during acute care in the ICU. This condition is referred to as ICU-acquired weakness (ICUAW), and can be evoked by critical illness polyneuropathy (CIP), critical illness myopathy (CIM), or critical illness polyneuromyopathy (CIPNM). ICUAW is diagnosed using the Medical Research Council (MRC) sum score based on bedside manual muscle testing in cooperative patients. The MRC sum score is the sum of the strengths of the 12 regions on both sides of the upper and lower limbs. ICUAW is diagnosed when the MRC score is less than 48 points. However, some patients require electrodiagnostic studies, such as a nerve conduction study, electromyography, and direct muscle stimulation, to differentiate between CIP and CIM. Pulmonary rehabilitation in the ICU can be divided into modalities intended to remove retained airway secretions and exercise therapies intended to improve respiratory function. Physical rehabilitation, including early mobilization, positioning, and limb exercises, attenuates the weakness that occurs during critical care. To perform mobilization in mechanically ventilated patients, pretreatment by removing secretions is necessary. It is also important to increase the strength of respiratory muscles and to perform lung recruitment to improve mobilization in patients who are weaned from the ventilator. For these reasons, pulmonary rehabilitation is important in addition to physical therapy. Early recognition of CIP, CIM, and CIPNM and early rehabilitation in the ICU might improve patients’ functional recovery and outcomes.

Abstract
Introduction Acute rehabilitation in critically ill patients can improve post-intensive care unit (post-ICU) physical function. In-bed cycling early in a patient's ICU stay is a promising intervention. The objective of this study was to determine the feasibility of recruitment, intervention delivery and retention in a multi centre randomised clinical trial (RCT) of early in-bed cycling with mechanically ventilated (MV) patients. Methods We conducted a pilot RCT conducted in seven Canadian medical-surgical ICUs. We enrolled adults who could ambulate independently before ICU admission, within the first 4 days of invasive MV and first 7 days of ICU admission. Following informed consent, patients underwent concealed randomisation to either 30 min/day of in-bed cycling and routine physiotherapy (Cycling) or routine physiotherapy alone (Routine) for 5 days/week, until ICU discharge. Our feasibility outcome targets included: accrual of 1-2 patients/month/site; >80% cycling protocol delivery; >80% outcomes measured and >80% blinded outcome measures at hospital discharge. We report ascertainment rates for our primary outcome for the main trial (Physical Function ICU Test-scored (PFIT-s) at hospital discharge). Results Between 3/2015 and 6/2016, we randomised 66 patients (36 Cycling, 30 Routine). Our consent rate was 84.6 % (66/78). Patient accrual was (mean (SD)) 1.1 (0.3) patients/month/site. Cycling occurred in 79.3% (146/184) of eligible sessions, with a median (IQR) session duration of 30.5 (30.0, 30.7) min. We recorded 43 (97.7%) PFIT-s scores at hospital discharge and 37 (86.0%) of these assessments were blinded. Discussion Our pilot RCT suggests that a future multicentre RCT of early in-bed cycling for MV patients in the ICU is feasible. Trial registration number NCT02377830.

Abstract
INTRODUCTION Neuromuscular weakness resulting in severe functional impairment is common in critical care survivors. This study aimed to evaluate effects of an early progressive rehabilitation intervention in mechanically ventilated adults at risk. METHODS This was a parallel, two-arm, assessor-blinded, randomised controlled trial with 6-months follow-up that was conducted in a mixed ICU of an academic centre in Switzerland. Previously independent, mechanically ventilated, critically ill adults with expected critical care stay ≥72 hours (n = 115) were randomised to a control group receiving standard physiotherapy including early mobilisation or to an experimental group with early endurance and resistance training combined with mobilisation. Primary endpoints were functional capacity (6-Minute Walk Distance) and functional independence (Functional Independence Measure) at hospital discharge. Secondary endpoints including muscle strength were assessed at critical care discharge. Safety was monitored closely by standard monitoring and predefined adverse events. RESULTS Physiotherapy started within 48 hours of critical care admission while 97% of participants were still ventilated and 68% on inotropes. Compared to the control group (n = 57), the experimental group (n = 58) received significantly more physiotherapy (sessions: 407 vs 377, p<0.001; time/session: 25min vs 18min, p<0.001) and had less days with sedation (p<0.001). Adverse events were rare (0.6%) and without consequences. There were no significant between-group differences in 6-Minute Walk Distance (experimental 123m (IQR 25-280) vs control 100m (IQR 0-300); p = 0.542) or functional independence (98 (IQR 66-119) vs 98 (IQR 18-115); p = 0.308). Likewise, no differences were found for the secondary outcomes, except a trend towards improved mental health in the experimental group after 6 months (84 (IQR 68-88) vs 70 (IQR 64-76); p = 0.023). CONCLUSIONS Early endurance and resistance training in mechanically ventilated, intensive care patients does not improve functional capacity or independence at hospital discharge compared to early standard physiotherapy but may improve mental health 6-months after critical care discharge.

Abstract
Muscle wasting occurs rapidly within days of an admission to the intensive care unit (ICU). Concomitant muscle weakness and impaired physical functioning can ensue, with lasting effects well after hospital discharge. Early physical rehabilitation is a promising intervention to minimize muscle weakness and physical dysfunction. However, there is an often a delay in commencing active functional exercises (such as sitting on the edge of bed, standing and mobilizing) due to sedation, patient alertness, and impaired ability to cooperate in the initial days of ICU admission. Therefore, there is high interest in being able to intervene early through nonvolitional exercise strategies such as electrical muscle stimulation (EMS). Muscle health characterized as the composite of muscle quantity, as well as functional and metabolic integrity, may be potentially maintained when optimal nutrition therapy is provided in complement with early physical rehabilitation in critically ill patients; however, the type, dosage, and timing of these interventions are unclear. This article explores the potential role of nutrition and EMS in maintaining muscle health in critical illness. Within this article, we will evaluate fundamental concepts of muscle wasting and evaluate the effects of EMS, as well as the effects of nutrition therapy on muscle health and the clinical and functional outcomes in critically ill patients. We will also highlight current research gaps in order to advance the field forward in this important area.
