Lung volume recruitment and airway clearance for children at home in France.

BACKGROUND: Airway clearance (ACT) and lung volume recruitment (LVR) techniques are used to manage bronchial secretions, increase cough efficiency and lung/chest wall recruitment, to prevent and treat respiratory tract infections. The aim of the study was to review the prescription of ACT/LVR techniques for home use in children in France. METHODS: All the centers of the national pediatric noninvasive ventilation (NIV) network were invited to fill in an anonymous questionnaire for every child aged ≤20 years who started a treatment with an ACT/LVR device between 2022 and 2023. The devices comprised mechanical in-exsufflation (MI-E), intermittent positive pressure breathing (IPPB), intrapulmonary percussive ventilation (IPV), and/or invasive mechanical ventilation (IMV)/NIV for ACT/LVR. RESULTS: One hundred and thirty-nine patients were included by 13 centers. IPPB was started in 83 (60 %) patients, MI-E in 43 (31 %) and IPV in 30 (22 %). No patient used IMV/NIV for ACT/LVR. The devices were prescribed mainly by pediatric pulmonologists (103, 74 %). Mean age at initiation was 8.9 ± 5.6 (0.4-18.5) years old. The ACT/LVR devices were prescribed mainly in patients with neuromuscular disorders (n = 66, 47 %) and neurodisability (n = 37, 27 %). The main initiation criteria were cough assistance (81 %) and airway clearance (60 %) for MI-E, thoracic mobilization (63 %) and vital capacity (47 %) for IPPB, and airway clearance (73 %) and repeated respiratory exacerbations (57 %) for IPV. The parents were the main carers performing the treatment at home. CONCLUSIONS: IPPB was the most prescribed technique. Diseases and initiation criteria are heterogeneous, underlining the need for studies validating the indications and settings of these techniques.

Body Mass Index and Thoracic Expansion in Post-COVID Dyspnea: A Secondary Analysis.

Dyspnea secondary to lung impairment can persist following the acute phase of COVID-19. Thoracic expansion measurements have been used as a diagnostic tool to evaluate chest wall mobility, respiratory function, and the effects of respiratory muscle strength training. Changes in chest wall mobility may occur because of altered chest biomechanics in individuals with respiratory diseases and an elevated body mass index (BMI). The purpose of this secondary analysis was to evaluate whether BMI influences thoracic expansion or forced expiratory volume over 1 second (FEV1) in individuals with persistent dyspnea following COVID-19. This study assessed the relationship between BMI and thoracic expansion, pulmonary symptoms, and exercise capacity following a home-based pulmonary rehabilitation intervention. A secondary data analysis was conducted with a sample of 19 adults with persistent dyspnea following COVID-19 infection who participated in a 12-week, home-based pulmonary rehabilitation study. Participants received expiratory muscle strength training devices and were instructed to perform pulmonary rehabilitation exercises three times per week over the study period. Pulmonary function, pulmonary symptoms, exercise capacity, and BMI measurements were collected. For analysis, study participants were divided into obese (BMI > 30 kg/m2) or nonobese (BMI < 30 kg/m2) categories. Correlations using the change scores from baseline to 12 weeks between thoracic expansion, FEV1, pulmonary symptoms, and exercise capacity were assessed. In addition, the minimal detectable change (MDC) in thoracic expansion was explored. Thoracic expansion was significantly improved after 12 weeks of training (p = .012) in the nonobese group. There was a significant correlation between the change in walking distance and pulmonary symptoms (r = -.738, p < .001) and in thoracic expansion (r = .544, p = .020), and walking distance, when controlling for BMI, but no change in FEV1. Average MDC was 1.28 for inspiration and 0.91 for expiration. Measurements of thoracic expansion were significantly lower in post-COVID individuals with an increased BMI. Individuals with persistent dyspnea and a higher BMI may require additional measures to increase chest mobility or to detect pulmonary changes following COVID-19.

Strategy nursing in children with compromised ventilation: Umbrella review.

PROBLEM: Changes in the ventilation demand nursing interventions duly adapted to the management of said impairment and to the adaptability of the child/parents. This revision aimed to investigate the evidence behind the interventions performed on children with impaired ventilation.' ELIGIBILITY CRITERIA: Systematic reviews of literature in English, Spanish, French, and Portuguese from studies on nursing interventions related to children with impaired ventilation in all contexts of the clinical practice. The Joanna Briggs Institute recommendations were followed. SAMPLE: We conducted a comprehensive search as of January 2022 and updated as of June 2023. The following electronic databases were searched: SCOPUS, Web of Science, Joanna Briggs Institute Database of Systematic Reviews and Implementation Reports, MEDLINE (via PubMed), CINAHL (via EBSCO), MedicLatina (via EBSCO), The Cochrane Database of Systematic Reviews (via EBSCO), and Database of Abstracts of Reviews of Effects (DARE). Nineteen articles published between 2012 and 2022 were included in this review. RESULTS: Nineteen studies investigated the efficacy of respiratory exercises (Breathing Control - relaxed breathing, pursed lip breathing, Diaphragmatic breathing exercises, respiratory expansion exercise - deep breathing exercise, thoracic expansion exercises (with device), exercises for respiratory muscle strengthening and position to optimize ventilation. In the majority of the studies, it was not possible to evaluate the interventions separately. Thirteen studies evidenced the efficacy of respiratory exercises, BIPAP, and oxygen therapy. Seven articles demonstrated the effectiveness of respiratory muscle-strengthening exercises, and only three mentioned the efficacy of positioning regarding impaired ventilation. Interventions based on respiratory exercises and respiratory muscle training were the most common ones. CONCLUSIONS: The results suggest that nursing interventions to optimize ventilation are efficient. Nevertheless, the same present a low to moderate evidence degree, justified by the population characteristics (small and heterogeneous). IMPLICATIONS: There is proof of evidence for the studied interventions. However, the lack of methodological robustness points to future research to duly describe interventions, data, and comparable results, using reliable samples in which the focus of the study is clear.

Rehabilitation in a Pediatric Patient Who Underwent Correction Surgery for Tetralogy of Fallot: A Case Report.

Tetralogy of Fallot (TOF) is a congenital heart defect characterized by four distinct heart abnormalities, which include an overriding aorta (where the aorta crosses both ventricles), a ventricular septal defect (VSD), right ventricular hypertrophy (the right ventricle muscle is thickened), and pulmonary stenosis (the pulmonary valve and artery are narrowed). Individuals suffering from TOF may exhibit pinkness, cyanosis at baseline, or episodes of hypercyanosis. The pathoanatomy of the TOF allows blood from the pulmonary and systemic circulations to mix. Cyanosis is caused by the addition of deoxygenated blood from a shunt that runs from right to left to the systemic circulation. In this case report, we present a five-year-old female patient with a known case of TOF. The results were recorded using the Pediatric Quality of Life (PedsQL) Questionnaire, New York Heart Association (NYHA) Dyspnoea Scale, Wong-Baker Faces Pain Rating Scale, and arterial blood gas analysis. Therapy goals were to improve overall functional ability, to remove secretions from airway, and the return of acceptable cardiovascular function. This case report focuses on the success of the cardiorespiratory rehabilitation program based on the patient's current state of health. The outcome parameters confirm that patients can experience improved functional recovery.

Novel median thoracic expansion for asphyxiating thoracic dystrophy.

There are several surgical techniques for asphyxiating Thoracic Dystrophy (ATD), and various techniques have various indications, but no one has studied this problem in the past. We designed a new procedure for the type of ATD with narrow and cylindrical thorax, and clinical results show that this method is reasonable for this type of patient.

Effect of thoracic expansion restriction on scapulothoracic and glenohumeral joint motion during shoulder external rotation.

BACKGROUND: Shoulder external rotation in the throwing motion involves movement of the scapulothoracic and glenohumeral joints, thoracic spine, and the thorax. Restriction of thoracic expansion may decrease scapulothoracic joint motion and compensate by excessive glenohumeral joint motion. However, it is unclear how restricting the expansion of the thorax alters shoulder motion. OBJECTIVE: To elucidate changes in scapulothoracic and glenohumeral joint movements caused by restricted thoracic expansion. METHODS: Kinematic data were obtained using an electromagnetic tracking device (Liberty; Polhemus), from 18 male participants, during shoulder external rotation in the sitting position with and without restriction of thoracic expansion. The displacements from the start position to the maximum external rotation position were compared, and Pearson's correlation coefficient was calculated. RESULTS: A significant difference was observed in the scapulothoracic posterior tilt angle (P< 0.01) and glenohumeral external rotation angle (P< 0.01). A significant positive correlation existed between scapulothoracic posterior tilt and glenohumeral external rotation (P< 0.05) with and without restriction. CONCLUSIONS: Restriction of thoracic expansion decreased scapulothoracic motion and increased glenohumeral motion. Thus, a decrease in thoracic expansion may change scapulothoracic and glenohumeral movements, which may be a risk factor for throwing injuries.

A new technique for neonatal Jeune syndrome: External thoracic expansion.

Jeune syndrome is a rare form of skeletal dysplasia characterized by a narrow, bell-shaped chest (thoracic cage), and typical phalangeal and pelvic bone deformities. Chest expansion is impaired by the short, horizontally positioned ribs, resulting in alveolar hypoventilation and eventually neonatal-infantile death in most cases. External distraction with sternoplasty is a new technique for the treatment of Jeune syndrome, which was firstly used by our team on a newborn by placing a sliding finger fixator which was designed for ulnar lengthening. We believe that this approach can be life-saving in neonates with improved and widespread usage.

Distraction osteogenesis of the sternum for thoracic expansion in a severe case of jeune syndrome: a preliminary report.

Severe asphyxiating thoracic dystrophy (Jeune syndrome) is usually fatal. The authors used distraction osteogenesis in a severe case and achieved 45 mm distraction of the sternum and improvement in tidal volume, lung compliance, and mean airway pressure.

Influência das técnicas de terapia manual osteopática na função respiratória / Influence of osteopathic manual therapy techniques in the respiratory function

As técnicas de terapia manual são consideradas como um método sistemático de avaliação e tratamento das disfunções do sistema neuromusculoesquelético, e estas têm como finalidade principal recuperar o movimento fisiológico em áreas onde existe restrição ou disfunção melhorando a função dos sistemas adjacentes. Contudo, na literatura são escassos os estudos sobre a utilização e eficácia destas técnicas, seja manipulativa ou de mobilização, na função respiratória, principalmente como uma forma preventiva de tratamento. O objetivo deste estudo foi avaliar as alterações nas funções pulmonares e na expansibilidade torácica em indivíduos normais submetidos às técnicas osteopáticas. Este estudo foi caracterizado como quase experimental. Fizeram parte da amostra 30 voluntárias, com idade de 18 à 28 anos, sem patologias pulmonares conhecidas associadas. A avaliação da função pulmonar e expansibilidade torácica foram por meio da espirometria e cirtometria respectivamente. A amostra recebeu procedimento de intervenção sendo avaliada em dois momentos, antes e após a aplicação de uma manobra osteopática de manipulação (thrust) em coluna torácica e técnica de músculo energia para peitorais. Os resultados indicam que o protocolo foi capaz de aumentar a mobilidade torácica em todos os parâmetros avaliados, e na função pulmonar houve melhora estatisticamente significativa no pico de fluxo expiratório.

Manual therapy techniques are considered to be a systematic method of assessment and treatment of disorders of the neuromusculoskeletal system, and are intended to recover the main physiological movement in areas where there is restriction or dysfunction, by improving the function of adjacent systems. However, in literature, there are few studies on the use and effectiveness of such techniques, whether by manipulative or mobilization techniques, in respiratory function, especially as preventive treatment. The aim of this study was to evaluate changes in lung function and chest expansion in normal individuals subjected to osteopathic techniques. This study was characterized as quasi-experimental. The sample consisted of 30 volunteers, aged 18 to 28 years, without known lung diseases associated. The evaluation of lung function and chest expansion were calculated using spirometry and circumference measurements, respectively. The sample received intervention procedure and was evaluated in two phases, before and after applying a move osteopathic manipulation (thrust) in the thoracic spine and the muscle energy technique for pectoral muscles. The results indicate that the protocol was able to increase thoracic mobility in all parameters, and lung function was statistically significantly improvement in peak expiratory flow.

Reconstruction of thoracic burn sequelae by scar release and flap resurfacing.

INTRODUCTION: In the USA, 450,000 thermal burns receive medical treatment annually. Burn scars are commonly excised and covered with skin grafts. Long-term, these treatments commonly leave patients with discomfort, reduced total lung capacity and forced vital capacity, and restriction of thoracic expansion and shoulder joint mobility. In this article, we present our experience with using scar release and immediate flap reconstruction to treat thoracic restriction due to burn sequelae. METHODS: From 1998 to 2014, we enrolled 16 patients with anterior thoracic burn sequelae that had previously been treated conservatively or with skin grafts that eventually recidivated. Preoperatively, we measured thoracic circumference in expiration and inspiration, %FVC, %FEV1, and shoulder mobility. All patients underwent anterior thoracic scar release and immediate flap resurfacing. RESULTS: At 2 weeks to 3 months postoperatively (mean, 2.6 months), mean thoracic circumference upon inspiration increased from 83.6 cm±5.7 to 86.5 cm±5.8 (p<0.0000000001). Mean %FVC improved from 76.0%±2.64% to 88.2%±4.69% (p<0.0000001). Mean %FEV1 improved from 79.2%±3.85 to 87.8%±2.98 (p<0.000001). All 14 patients who had restricted shoulder mobility preoperatively no longer had restricted shoulder mobility postoperatively. The mean patient-reported satisfaction was 4.6/5 (range, 3-5). At a mean follow up of 2.5 years, none of the contractures recidivated. Complications included 2 cases of tissue necrosis of the distal end of the flap. In one case, the flap was restored; in the other case, the patient eventually had to receive a new flap. Additional complications included two local infections that were successfully treated with oral and local antibiotics and two hematomas that were drained and eventually healed without tissue loss. CONCLUSIONS: Scar releases and flaps provide a safe and effective method for the correction of restricted thoracic expansion, respiratory restriction, decreased range of shoulder motion, and discomfort from thoracic burn sequelae.
