Respiratory Muscle Weakness

Background: Increased frequency of chest infections in acute stroke patients may be the result of respiratory muscle weakness contributing to a weak cough and poor airway clearance. We undertook a systematic review of studies comparing respiratory muscle strength in acute stroke patients with age-matched controls. Method: A systematic review of literature was performed using the electronic databases Medline, EMBASE, ISI web of knowledge and the Scopus. The key words searched were stroke or cerebrovascular accident in combination with cough, inspiratory, expiratory or respiratory and strength or weakness. Studies were included if they compared stroke patients with age matched controls and measured maximum inspiratory or expiratory mouth pressure (PImax and PEmax) for inspiratory and expiratory muscle strength respectively. Results: The initial search identified 136 articles, 14 of which remained after screening for pre-defined inclusion criteria and removal of duplicates. Eleven were excluded after reviewing abstracts (5 did not assess muscle strength, 5 did not include healthy control group, 1 absolute values could not be obtained). A further study was identified from the reference lists of screened articles. The 4 studies that met inclusion criteria included 121 subjects. Mean PImax ranged from 75-99 cmH 2 O in controls and 37-74 cmH 2 O in stroke patients. (mean difference 41 cmH 2 O, 95% CI 54 to 29 cm H 2 O; P<0.0001). Mean PEmax ranged from 52-89 cm H 2 O in stroke patients and was also reduced compared with age matched controls (mean difference 55 cmH 2 O, 95% CI 61 to 48 cmH 2 O; P<0.0001). ( Fig 1 ). Conclusion: Individual studies and pooled data suggest that respiratory muscle strength is impaired in acute stroke patients. However, these studies are limited by small samples and design heterogeneity. Larger studies are needed to assess the relationship of respiratory muscle weakness with chest infections and clinical outcomes in the acute phase.

Respiratory Muscle Weakness

Introduction: The respiratory muscle strength regulates the effectiveness of coughing, which clears the airways and protects people from pneumonia. Sarcopenia is an aging-related loss of muscle mass and function, the worsening of which is associated with malnutrition. The loss of respiratory and swallowing muscle strength occurs with aging, but its effect on pneumonia is unclear. This study aimed to determine the risks of respiratory muscle weakness on the onset and relapse of pneumonia in older people in conjunction with other muscle-related factors such as malnutrition. Methods: We conducted a longitudinal study with 47 pneumonia inpatients and 35 non-pneumonia controls aged 70 years and older. We evaluated the strength of respiratory and swallowing muscles, muscle mass, and malnutrition (assessed by serum albumin levels and somatic fat) during admission and confirmed pneumonia relapse within 6 months. The maximal inspiratory and expiratory pressures determined the respiratory muscle strength. Swallowing muscle strength was evaluated by tongue pressure. Bioelectrical impedance analysis was used to evaluate the muscle and fat mass. Results: The respiratory muscle strength, body trunk muscle mass, serum albumin level, somatic fat mass, and tongue pressure were significantly lower in pneumonia patients than in controls. Risk factors for the onset of pneumonia were low inspiratory respiratory muscle strength (odds ratio [OR], 6.85; 95% confidence interval [CI], 1.56–30.11), low body trunk muscle mass divided by height2 (OR, 6.86; 95% CI, 1.49–31.65), and low serum albumin level (OR, 5.46; 95% CI, 1.51–19.79). For the relapse of pneumonia, low somatic fat mass divided by height2 was a risk factor (OR, 20.10; 95% CI, 2.10–192.42). Discussion/Conclusions: Respiratory muscle weakness, lower body trunk muscle mass, and malnutrition were risk factors for the onset of pneumonia in older people. For the relapse of pneumonia, malnutrition was a risk factor.

Introduction 238 Assessment 239 Treatment 240 A variety of neuromuscular disorders may affect the ventilatory pump at different sites (Table 37.1). Most of these disorders result in respiratory muscle weakness, which results in alveolar hypoventilation and impaired cough. Patients with known neuromuscular disease may present acutely with a presentation related to their underlying neuromuscular disease (such as infection) or occasionally in end-stage ventilatory failure....
