Filter by:Transcutaneous electrical phrenic nerve stimulation (TEPNS) and transcutaneous electrical diaphragm stimulation (TEDS) are modalities that use surface electrodes placed on the patients' skin to generate action potentials and contractions of the muscle fibers of the diaphragm. The primary objective will be to evaluate the efficacy of TEPNS and TEDS in healthy adult individuals. Secondary objectives will be to assess the feasibility, safety, and level of discomfort reported by the individual resulting from the application of TEPNS and TEDS.
Currently, measurement of transdiaphragmatic pressure (Pdi) using oesophageal and gastric balloons is the gold standard for the assessment of diaphragmatic effort. This technique is relatively invasive and its interpretation may be complex. The diaphragmatic longitudinal strain (LSdi) and strain rate (LSRdi) might provide additional information in the assessment of diaphragmatic effort and movement during SBT, allowing early detection of diaphragmatic dysfunction. Patients will be monitored during a 30-120 minutes SBT consisting of no assistance on the ventilator using CPAP with a pressure level of 0 cmH2O. Parameters to evaluate diaphragm function will include diaphragmatic strain (LSdi and LSRdi), diaphragmatic thickening fraction (TFdi), and airway occlusion pressure (ΔP0.1 and ΔPocc). These parameters will be measured immediately before ('baseline') the SBT, as well as 2 minutes ('early' assessment), 15 ('intermediate' assessment) and 30 minutes ('late' assessment) after the beginning of the SBT.
Background of the study: Increased work of breathing, potentially leading to respiratory insufficiency, resulting in the need of (non-) invasive respiratory support is the most common observed problem in the neonatal - and pediatric intensive care unit (NICU/PICU). The diaphragm is the main respiratory muscle. Currently there is not an established technique accessible to observe the (clinical) function of the diaphragm and its role in respiratory insufficiency. New non-invasive modalities are promising, such as transcutaneous diaphragm electromyography (dEMG) and diaphragm ultrasound (dUS). Objective of the study: Our objective is to assess the association between transcutaneous diaphragm electromyography (dEMG) and diaphragm ultrasound (dUS) in the PICU population. Study design: Single center pilot study Study population: The study population consists of children between 0-12 months, admitted to the PICU of the Leiden University Medical Center, with invasive respiratory support. Primary study parameters/outcome of the study: Primary endpoint is to evaluate the association between dEMG and dUS measurements in the PICU population.
With increasing usage of electronic devices and sedentary lifestyle, chronic neck pain has become a more prevalent musculoskeletal disorder around the world. Many impairments have been identified in people with chronic neck pain including pain, muscle weakness, proprioceptive deficits and altered breathing pattern. Diaphragm is the key muscle for inspiration and also plays an important role in spinal stability. Previous studies have found that diaphragm functions are related to the stability of the lumbar spine through the fascial, neural and visceral systems. Diaphragmatic resistance training thus could have some positive effects on reducing pain and disability in people with low back pain. However, to date how diaphragmatic resistance training would affect chronic neck pain is still unknown. Therefore, the purpose of this study is to investigate the effects of diaphragmatic resistance training on pain, disability and movement quality in people with chronic neck pain.
This prospective study aims at evaluating diaphragmatic function before and after endobronchial valves positioning in a COPD patients with lung hyperinflation.
Brief Summary: Low back pain is very common problem in all the developed countries and affects children to elderly. Based on the etiology the low back pain is divided into two type: nonspecific and specific low back pain. If the pathological reason is known it is defined as specific and if the reason for the pain is unknown it is defined as nonspecific low back pain. The postulated reason for nonspecific low back pain is the segmental instability of the lumbar spine. Diaphragm muscle has a role in maintaining the segmental stability. The aim of this study to reduce the severity of the low back pain with improving the stability of the lumbar spine by using diaphragm training.
Fifteen healthy subjects under non-invasive ventilation will be have a recording of surface electromyogram, measurements of airway flows and pressures as well as a continuous ultrasound. The provocation of leaks on the Ventilation circuit and expiratory trigger modulation will generate a number of asynchronies between the subject and the respirator. These records will help to assess the agreement between the detection of asynchronies using electromyography of the respiratory muscles (technique of reference) and the diaphragmatic echography. We will also compare the respective performance of two techniques of diaphragmatic exploration (excursion and thickening of the diaphragm). A sensitivity of Ultrasound technique of at least 90% will be interpreted as a satisfactory index of concordance.
Worldwide, esophageal cancer is the 6th most common cause of cancer-related death. Currently curative resection remains the cornerstone of the therapy. Despite advances in anesthesia, operative techniques and postoperative management, postoperative pulmonary complications (PPCs) occur frequently accounting for about 30% of all postoperative complications. Most importantly, PPCs have much been associated with postoperative mortality. The diaphragm is the most important respiratory muscle and its respiratory function would be inevitably damaged when esophagectomy is performed through the left posterolateral thoracotomy (Sweet procedure) because the diaphragm must be dissected for the purpose of stomach moralization. Meanwhile, Ivor-Lewis approach may effectively avoid diaphragm injury because the stomach can be managed through a laparotomy whereas an additional abdomen incision is needed. Both procedures are routinely used in practice when surgically managing esophageal cancer. The investigators hypothesize that Ivor-Lewis procedure might be superior to the left-thoracotomy route during esophagectomy in preventing PPCs.
