ABSTRACT: Objective
To estimate the effectiveness of Neuromuscular Electrostimulation (NMES) in adults with COPD undergoing MV.Method
A sensitive search was performed in MEDLINE, Embase, CENTRAL, CINAHL and other resources. Randomized Controlled Clinical Trials (RCTs) or non-RCTs that enrolled adults with COPD on MV due to an exacerbation of their disease were included. Two independent reviewers screened, extracted information, and assessed the risk of bias (RoB 2 tool) and the certainty of evidence (GRADE approach) from the included studies.Results
Four RCTs (144 participants) were included. Subjects who underwent NMES were able to move from bed to chair independently in less time (MD = 4.98 days less; 95% CI -8.55 to -1.47; 2 RCTs; low certainty of the evidence) and they were fewer days on MV (MD = 2.89 days less; 95% CI -4.58 to -1.21); 3 RCTs; low certainty of the evidence) than the control group. However, the effect of NMES on muscle strength is unclear (very low certainty of the evidence).Conclusions
NMES may improve functional independence and decrease MV time in adults with COPD; however, its effectiveness on muscle strength is uncertain. More and better RCTs are needed to determine with greater certainty the effectiveness of NMES in this population.

Project description:ObjectiveThis systematic review aimed in assessing the effects of different weaning protocols in people with neuromuscular disease (NMD) receiving invasive mechanical ventilation, identifying which protocol is the best and how different protocols can affect weaning outcome success, duration of weaning, intensive care unit (ICU) and hospital stay and mortality.DesignSystematic review.Data sourcesElectronic databases (MEDLINE, EMBASE, Web of Science and Scopus) were searched from January 2009 to August 2020.Eligibility criteria for selecting studiesRandomised controlled trials (RCTs) and non-RCT that evaluated patients with NMD (adults and children from 5 years old) in the weaning process managed with a protocol (pressure support ventilation; synchronised intermittent mandatory ventilation; continuous positive airway pressure; 'T' piece).Primary outcomeWeaning success.Secondary outcomesWeaning duration, ICU stay, hospital stay, ICU mortality, complications (pneumothorax, ventilation-associated pneumonia).Data extraction and synthesisTwo review authors assessed the titles and the abstracts for inclusion and reviewed the full texts independently.ResultsWe found no studies that fulfilled the inclusion criteria.ConclusionsThe absence of studies about different weaning protocols for patients with NMD does not allow concluding the superiority of any specific weaning protocol for patients with NMD or determining the impact of different types of protocols on other outcomes. The result of this review encourages further studies.Prospero registration numberCRD42019117393.

Project description:BackgroundNeuromuscular electrical stimulation (NMES) is widely used as a rehabilitation methods to restore muscle mass and function in prolonged immobilization individuals. However, its effect in mechanically ventilated patients to improve clinical outcomes remains unclear.MethodsA comprehensive search was conducted using PubMed, Embase, Web of Science, PEDro, and the Cochrane Library from their inception until December 24th, 2023. The search targeted randomized controlled trials (RCTs) comparing NMES with physical therapy (PT) or usual ICU care (CG), for improving clinical outcomes in mechanically ventilated patients. We performed a network meta-analysis utilizing Stata version 14.0 and R 4.3.1.ResultsWe included 23 RCTs comprising 1312 mechanically ventilated adults. The treatments analyzed were NMES, PT, NMES combined with PT (NMES+PT), and CG. Network meta-analyses revealed that NMES or NMES+PT significantly improved extubation success rate compared to CG, with ORs of 1.85 (95% CI: 1.11, 3.08) and 5.89 (95% CI: 1.77, 19.65), respectively. Additionally, NMES exhibited a slight decrease in extubation success rate compared with NMES+PT, with OR of 0.31 (95% CI: 0.11, 0.93). Nevertheless, neither NMES nor NMES+PT showed any significant improvement in ICU length of stay (LOS), ventilation duration, or mortality when compared with PT or CG. NMES+PT emerged as the most effective strategy for all considered clinical outcomes according to the ranking probabilities. The evidence quality ranged from "low" to "very low" in this network meta-analysis.ConclusionsNMES appears to be a straightforward and safe modality for critically ill, mechanically ventilated patients. When combined with PT, it significantly improved the extubation success rate against standard ICU care and NMES alone, and showed a better ranking over PT or NMES alone for clinical outcomes. Therefore, NMES combined with PT may be a superior rehabilitation strategy for this patient group.

Project description:IntroductionNeuromuscular diseases (NMD) are characterised by progressive muscular impairment. The muscle weakness is directly related to respiratory muscles weakness, causing reduction in vital capacity, especially when associated with mechanical ventilation (MV). Conventional MV weaning in NMD is generally difficult. Weaning process can be conducted in protocols such as: 'T' piece or Pressure Support Ventilaton. Weaning failure is frequent because of muscle weakness. Protocol aim is to assess the effects of different weaning protocols in NMD patients receiving invasive MV in weaning success rate, duration of weaning, intensive care unit (ICU) stay, hospital stay and ICU mortality.Methods and analysisA search will be carried in the Cochrane Neuromuscular Specialised Register, MEDLINE, EMBASE, Web of Science, Scopus, United States National Institutes of Health Clinical Trials Registry, ClinicalTrials.gov and WHO International Clinical Trial Registry Protal, of randomised controlled trials (RCTs) and quasi-RCTs. Inclusion criteria of individuals are adults (above 16 years old) and children (from 5 to 16 years old), with clinical diagnosis of NMD (muscular dystrophy, amyotrophic lateral sclerosis, congenital myasthenia, myasthenia gravis, congenital myopathy, spinal muscular atrophy, Guillian Barré Syndrome, severe inherited neuropathies, metabolic myopathies, inflammatory myopathies, mitochondrial diseases) of any gender. All patients ventilated for at least 48 hours due to respiratory failure and clinically considered ready for weaning. Other respiratory or cardiovascular diagnosis associated will not be included. Intervention assessed will be weaning from MV using a protocol with 30 min to 2 hours of spontaneous breathing trial at the end point. All comparisons of different protocols will be considered.Ethics and disseminationFormal ethical approval is not required as primary data will not be collected, since it will be a systematic review. All studies included should have ethical committee approval. The results will be disseminated through a peer-reviewed publication and in conferences and congresses or symposia.Prospero registration numberCRD42019117393.

Project description:BackgroundSeveral measurements have been used to predict the success of weaning from mechanical ventilation; however, their efficacy varies in different studies. In recent years, diaphragmatic ultrasound has been used for this purpose. We conducted a systematic review and meta-analysis to evaluate the effectiveness of diaphragmatic ultrasound in predicting the success of weaning from mechanical ventilation.MethodsTwo investigators independently searched PUBMED, TRIP, EMBASE, COCHRANE, SCIENCE DIRECT, and LILACS for articles published between January 2016 and July 2022. The methodological quality of the studies was assessed using the Quality Assessment of Diagnostic Accuracy Studies-2 tool; additionally, the certainty of the evidence is evaluated using the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) methodology. Sensitivity and specificity analysis was performed for diaphragmatic excursion and diaphragmatic thickening fraction; positive and negative likelihood ratios and diagnostic odds ratios (DOR) with their confidence intervals (95% CI) were calculated by random effects analysis, summary receiver operating characteristic curve was estimated. Sources of heterogeneity were explored by subgroup analysis and bivariate meta-regression.ResultsTwenty-six studies were included, of which 19 were included in the meta-analysis (1204 patients). For diaphragmatic excursion, sensitivity was 0.80 (95% CI 0.77-0.83), specificity 0.80 (95% CI 0.75-0.84), area under the summary receiver operating characteristic curve 0.87 and DOR 17.1 (95% CI 10.2-28.6). For the thickening fraction, sensitivity was 0.85 (95% CI 0.82-0.87), specificity 0.75 (95% CI 0.69-0.80), area under the summary receiver operating characteristic curve 0.87 and DOR 17.2 (95% CI 9.16-32.3). There was heterogeneity among the included studies. When performing a subgroup analysis and excluding studies with atypical cutoff values, sensitivity and specificity increased for diaphragmatic thickening fraction; sensitivity increased and specificity decreased for diaphragmatic excursion; when comparing studies using pressure support (PS) versus T-tube, there was no significant difference in sensitivity and specificity; bivariate meta-regression analysis shows that patient position at the time of testing was a factor of heterogeneity in the included studies.ConclusionsMeasurement of diaphragmatic excursion and diaphragmatic thickening fraction predict the probability of successful weaning from mechanical ventilation with satisfactory diagnostic accuracy; however, significant heterogeneity was evident in the different included studies. Studies of high methodological quality in specific subgroups of patients in intensive care units are needed to evaluate the role of diaphragmatic ultrasound as a predictor of weaning from mechanical ventilation.

Project description:ObjectiveTo evaluate current practices of tracheostomy in children regarding the ideal timing of tracheostomy placement, complications, indications, mortality, and success in decannulation.Source of dataThe authors searched PubMed, Embase, Cochrane Library, Google Scholar, and complemented by manual search. The guidelines of PRISMA and MOOSE were applied. The quality of the included studies was evaluated with the Newcastle-Ottawa Scale. Information extracted included patients' characteristics, outcomes, time to tracheostomy, and associated complications. Odds ratios (ORs) with 95% CIs were computed using the Mantel-Haenszel method.Synthesis of dataSixty-six articles were included in the qualitative analysis, and 8 were included in the meta-analysis about timing for tracheostomy placement. The risk ratio for "death in hospital outcome" did not show any benefit from performing a tracheostomy before or after 14 days of mechanical ventilation (p = 0.49). The early tracheostomy before 14 days had a great impact on the days of mechanical ventilation (-26 days in mean difference, p < 0.00001). The authors also found a great reduction in hospital length of stay (-31.4 days, p < 0.008). For the days in PICU, the mean reduction was of 14.7 days (p < 0.007).ConclusionsThe meta-analysis suggests that tracheostomy performed in the first 14 days of ventilation can reduce the time spent on the ventilator, and the length of stay in the hospital, with no effect on mortality. The decision to perform a tracheostomy early or late may be more dependent on the baseline disease than on the time spent on ventilation .

Project description:BackgroundThe goal of this study was to evaluate the effects of resistance training on subjects with COPD.MethodsWe performed a systematic search in MEDLINE, PubMed, Embase, CINAHL, Elsevier ScienceDirect, EBM Reviews, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov and also of leading respiratory journals for randomized controlled trials on COPD treatment for ≥ 4 weeks with resistance training compared with non-exercise control or with combined resistance and endurance training compared with endurance training alone. Data from these studies were pooled to calculate odds ratio and weighted mean differences (WMDs) with 95% CI.ResultsEighteen trials with 750 subjects with advanced COPD met the inclusion criteria. There were 2 primary and 5 secondary outcomes. Compared with non-exercise control, resistance training led to significant improvements in the dyspnea domain of the Chronic Respiratory Disease Questionnaire (WMD of 0.59, 95% CI 0.26-0.93, I2 = 0%, P < .001), skeletal muscle strength, and percent-of-predicted FEV1 (WMD of 6.88%, 95% CI 0.41-13.35%, I2 = 0%, P = .04). The combination of resistance and endurance training significantly improved the St George Respiratory Questionnaire total score (WMD of -7.44, 95% CI -12.62 to -2.25, I2 = 0%, P = .005), each domain score, and skeletal muscle strength. There were no significant differences in 6-min walk distance, 6-min pegboard and ring test, maximum exercise work load, and maximum oxygen consumption between the 2 groups. There were no reports of adverse events related to resistance-training intervention.ConclusionsResistance training can be successfully performed alone or in conjunction with endurance training without increased adverse events during pulmonary rehabilitation in COPD.

Project description:ObjectiveTo describe the potential effects of ventilatory strategies on the outcome of acute brain-injured patients undergoing invasive mechanical ventilation.DesignSystematic review with an individual data meta-analysis.SettingObservational and interventional (before/after) studies published up to August 22nd, 2022, were considered for inclusion. We investigated the effects of low tidal volume Vt < 8 ml/Kg of IBW versus Vt > = 8 ml/Kg of IBW, positive end-expiratory pressure (PEEP) < or > = 5 cmH2O and protective ventilation (association of both) on relevant clinical outcomes.PopulationPatients with acute brain injury (trauma or haemorrhagic stroke) with invasive mechanical ventilation for ≥ 24 h.Main outcome measuresThe primary outcome was mortality at 28 days or in-hospital mortality. Secondary outcomes were the incidence of acute respiratory distress syndrome (ARDS), the duration of mechanical ventilation and the partial pressure of oxygen (PaO2)/fraction of inspired oxygen (FiO2) ratio.ResultsThe meta-analysis included eight studies with a total of 5639 patients. There was no difference in mortality between low and high tidal volume [Odds Ratio, OR 0.88 (95%Confidence Interval, CI 0.74 to 1.05), p = 0.16, I2 = 20%], low and moderate to high PEEP [OR 0.8 (95% CI 0.59 to 1.07), p = 0.13, I2 = 80%] or protective and non-protective ventilation [OR 1.03 (95% CI 0.93 to 1.15), p = 0.6, I2 = 11]. Low tidal volume [OR 0.74 (95% CI 0.45 to 1.21, p = 0.23, I2 = 88%], moderate PEEP [OR 0.98 (95% CI 0.76 to 1.26), p = 0.9, I2 = 21%] or protective ventilation [OR 1.22 (95% CI 0.94 to 1.58), p = 0.13, I2 = 22%] did not affect the incidence of acute respiratory distress syndrome. Protective ventilation improved the PaO2/FiO2 ratio in the first five days of mechanical ventilation (p < 0.01).ConclusionsLow tidal volume, moderate to high PEEP, or protective ventilation were not associated with mortality and lower incidence of ARDS in patients with acute brain injury undergoing invasive mechanical ventilation. However, protective ventilation improved oxygenation and could be safely considered in this setting. The exact role of ventilatory management on the outcome of patients with a severe brain injury needs to be more accurately delineated.

Project description:PurposeA systematic review and meta-analysis was conducted to answer the question 'In adults with respiratory failure requiring invasive ventilation for more than 24 h, does a weaning strategy with early extubation to non-invasive ventilation (NIV) compared to invasive ventilation weaning reduce all-cause hospital mortality?'MethodsWe included randomised and quasi-randomised controlled trials that evaluated the use of non-invasive ventilation, compared to invasive ventilation, as a weaning strategy in adults mechanically ventilated for at least 24 h. The EMBASE, MEDLINE and Cochrane Central Register of Controlled Trials (CENTRAL) bibliographic databases were searched from inception to February 2018. Bayesian hierarchical models were used to perform the meta-analysis. The primary outcome was mortality at hospital discharge. Secondary outcomes included mortality (30, 60, 90 and 180 days), quality of life, duration of invasive ventilation, weaning failure, length of stay [intensive care unit (ICU) and hospital] and adverse events.ResultsTwenty-five relevant studies involving 1609 patients were included in the quantitative analysis. Studies had moderate to high risk of bias due to risk of performance and detection bias. Mortality at hospital discharge was lower in the NIV weaning group compared to the invasive weaning group [pooled odds ratio (OR) 0.58, 95% highest density interval (HDI) 0.29-0.89]. Subgroup analyses showed lower pooled mortality at hospital discharge rates in NIV weaning than those in the control group in chronic obstructive pulmonary disease (COPD) patients (pooled OR 0.43, 95% HDI 0.13-0.81) and the effect is less certain in the mixed ICU population (pooled OR 0.88, 95% HDI 0.25-1.48). NIV weaning reduced the duration of invasive ventilation in patients [standardised mean difference (SMD) - 1.34, 95% HDI - 1.92 to - 0.77] and ICU length of stay (SMD - 0.70, 95% HDI - 0.94 to - 0.46). Reported rates of ventilator associated pneumonia (VAP) were lower in the NIV group. NIV weaning did not reduce overall hospital length of stay or long-term mortality. There were insufficient data to compare other adverse events and health-related quality of life.ConclusionsThe use of NIV in weaning from mechanical ventilation decreases hospital mortality, the incidence of VAP and ICU length of stay. NIV as a weaning strategy appears to be most beneficial in patients with COPD.

Project description:BackgroundUncertainty remains around the benefit of home non-invasive ventilation (NIV) for stable chronic obstructive pulmonary disease (COPD) patients and those with a recent exacerbation (post-hospital). The aim of this systematic review was to: (1) update the evidence base with studies published in any language, including Chinese language studies not indexed in standard medical databases, and (2) explore the impact of additional studies on the evidence base.MethodsStandard systematic review methodology was used for identifying and appraising studies. Randomized controlled trials (RCTs) and non-randomized studies reporting mortality, hospitalizations, exacerbations, quality of life, adverse events, or adherence were included. Random effects meta-analysis was undertaken for mortality and hospitalizations, with studies sub-grouped by population and study design. Sensitivity analysis was performed to explore the effect of including studies from Western and non-Western countries.ResultsA total of 103 studies were included, substantially more than in previous reviews. There was no significant effect on mortality for the stable population. There was a benefit from NIV for the post-hospital population based on non-randomized studies, or RCTs from non-Western countries. There was a small but significant reduction in hospital admissions (1-2/year) with NIV across all sub-groups, and a variable reduction in duration of stay with greater reductions in studies from China.ConclusionsThe evidence base on home NIV is considerably larger than previously presented. While NIV may reduce hospital admissions and improve quality of life, there is still little evidence of a reduction in mortality, regardless of country. Individual participant data analysis may clarify which patients would benefit most from NIV.

Project description:BackgroundThis systematic review aimed to assess inhaled drug delivery in mechanically ventilated patients or in animal models. Whole lung and regional deposition and the impact of the ventilator circuit, the artificial airways and the administration technique for aerosol delivery were analyzed.MethodsIn vivo studies assessing lung deposition during invasive mechanical ventilation were selected based on a systematic search among four databases. Two investigators independently assessed the eligibility and the risk of bias.ResultsTwenty-six clinical and ten experimental studies were included. Between 30% and 43% of nominal drug dose was lost to the circuit in ventilated patients. Whole lung deposition of up to 16% and 38% of nominal dose (proportion of drug charged in the device) were reported with nebulizers and metered-dose inhalers, respectively. A penetration index inferior to 1 observed in scintigraphic studies indicated major proximal deposition. However, substantial concentrations of antibiotics were measured in the epithelial lining fluid (887 (406-12,819) μg/mL of amikacin) of infected patients and in sub-pleural specimens (e.g., 197 μg/g of amikacin) dissected from infected piglets, suggesting a significant distal deposition. The administration technique varied among studies and may explain a degree of the variability of deposition that was observed.ConclusionsLung deposition was lower than 20% of nominal dose delivered with nebulizers and mostly occurred in proximal airways. Further studies are needed to link substantial concentrations of antibiotics in infected pulmonary fluids to pulmonary deposition. The administration technique with nebulizers should be improved in ventilated patients in order to ensure an efficient but safe, feasible and reproducible technique.
