Filter by:This study was conducted to investigate Effect of manual diaphragmatic activation on diaphragm function in patients with gastroesophageal reflux disease
The aim of this study is to test the effect of 1week of extracorporeal diaphragm pacing (EDP) combined either with or without tilt table verticalization (TTV) on diaphragm function in patients with mechanical ventilation compared to conventional physiotherapy (CPT).
The aims of the current study are as follows: i) Investigate the relationships between indices derived from ultrafast ultrasound imaging and Pditw, ii) Investigate the relationships between indices derived from ultrafast ultrasound imaging and diaphragm EMG, iii) Investigate the performance of ultrafast ultrasound for the diagnosis of diaphragm dysfunction, iv) Investigate the ability of ultrafast ultrasound imaging to decipher the cause of diaphragm dysfunction i.e. contractility alteration and/or phrenic nerves conduction defect.
In children undergoing pulmonary resection, the diaphragm function is evaluated using ultrasound before and after surgery to evaluate the incidence of diaphragm dysfunction after pulmonary resection. In addition, we examine if there is a relationship between diaphragmatic dysfunction and pulmonary complications, including postoperative lung atelectasis.
Although non-invasive mechanical ventilation (NIV) is the gold standard treatment for patients with acute exacerbation of COPD (AECOPD) who develop respiratory acidosis, failure rate are still high ranging from 5% to 40%. Recent studies have shown that the onset of severe diaphragmatic dysfunction (DD) during AECOPD increases risk of NIV failure and mortality in this subset of patients. Although the imbalance between the load and the contractile capacity of inspiratory muscles seems the main cause of AECOPD-induced hypercapnic respiratory failure, data regarding the influence of mechanical derangement on diaphragmatic performance in this acute phase are lacking. With this study we aim at investigating the impact of respiratory mechanics on diaphragm function in AECOPD patients who experienced NIV failure. AECOPD with respiratory acidosis admitted to the ICU of the University Hospital of Modena from 2017-2018 undergoing mechanical ventilation (MV) due to NIV failure were enrolled. The study protocol consisted of two consecutive phases; in the first step measurements of static respiratory mechanics and end expiratory lung volume (EELV) were performed after 30 minutes of MV in volume control mode. In the second step transdiaphragmatic pressure (Pdi) was calculated by means of a sniff maneuver (Maximal Pdi) after 30 minutes of spontaneous breathing trial. Linear regression analysis and Pearson's correlation coefficient was used to asses the association between Maximal Pdi values and static and dynamic mechanical features and the association between Maximal Pdi and Pdi/Maximal Pdi.
This non-interventional study focuses on mechanical ventilation used in intensive care unit to supplement ventilatory function in patients. Mechanical ventilation can "paradoxically" be at the origin of complications that can be life-threatening in patients. This muscular pathology is called ventilation-induced diaphragmatic dysfunction (DDIV). Diaphragmatic muscle collected during a digestive surgery for a benign or malignant tumor of the liver requiring surgical excision in contact with the diaphragm from the care will be conserved. The diaphragm biopsy from the care will be retained for biobanking to obtain myoblast in culture which will differentiate in Diaphragm fiber. Then these fibers will be submitted under mechanical stress condition similar to those imposed in vivo by mechanical ventilation to validate in human a model in vitro of diaphragm dysfunction induced by mechanical ventilation. Then the second part of the study will be to evaluate with this model, the efficiency of an antioxidant therapy.
