Filter by:Using an extensive set of both volitional and non-volitional tests of respiratory muscle function and strength it is the aim of this study to - identify disease-specific patterns of respiratory muscle impairment in different NMD and COPD - establish which set of tests is predictive of sleep-disordered breathing or daytime hypercapnia in patients with NMD or COPD, respectively. - to investigate the decline of respiratory muscle function in patients with progressive NMD and COPD along with sleep studies and capnography
The diaphragmatic pacemaker (DP) has proven its utility in replacing mechanical ventilation (MV) in patients with chronic spinal cord injury (SCI) and Amyotrophic Lateral Sclerosis (ALS), by improving the patients quality of life and reducing morbi-mortality and the associated health care costs. The anesthetic management of these patients and the particularities of the surgical procedure represent an anesthetic challenge. The objective of our study is to analyze the management and the intraoperative complications in the patients with DP in our institution.
1. INTRODUCTION AND MAIN OBJECTIVES The incidence of diaphragmatic paralysis after an inter-block scalénique varies between 30 and 100% in the literature. Its clinical impact is mostly absent and paralysis regresses after the block lifted. When it is suspected, it can be diagnosed by a chest radio, showing an elevation of the dome. The objective of this study is to evaluate the incidence of diaphragmatic paralysis by measuring the thickness diaphragmatic as quantitative assessment of diaphragmatic contraction noninvasive ultrasound scan and feasibility of this measure in SSPI unit (post-interventional monitoring unit) with scan (ultrasound) in the usual way used for the block under ultrasound scan. 2. STUDY TYPE Prospective, single-center clinical study routine care involving 50 consecutive patients scheduled to undergo surgical procedures in the area of the shoulder or arm for which locoregional analgesia inter-block type scalénique or supraclavicular ultrasound scan is indicated below. 3. START OF THE STUDY February 2014 with an expected duration of six months.
This study evaluates three different neuromuscular monitoring devices (acceleromyography, one- or three-dimensional, and electromyography) with regard to their precision to detect residual paralysis after injection of neuromuscular blocking agents and recurrence of paralysis after administration of reversal agents in a clinical setting.
Critical illness neuromyopathy is a common disease acquired during ICU stay leading to a deep weakness involving the respiratory muscle work which result in a delayed weaning of mechanical ventilation. The main objective is to quantify the loss of diaphragm function by measuring the diaphragm force (using the non invasive method by phrenic nerve stimulation allowing to measure the twitch airway pressure during airway occlusion) in a selected population of patients with critical illness neuromyopathy (defined as a MRC score < 48). The second end points are to evaluate its incidence, the consequences on the patients outcome (extubation success or failure; ICU stay) and to evaluate the relations between diaphragm function (twitch airway pressure during airway occlusion, maximal inspiratory pressure and diaphragm thickness evaluated by ultrasound) and peripheral limbs force (evaluated by the Medical Research Council - MRC score).
The aim of this study is to better discriminate respiratory muscle dysfunction by comparing the measurements of thoracoabdominal motion obtained by an optoelectronic recording and the conventional tests of respiratory muscle strength. The final objective is to better select in the future the patients who need more specific assessment of diaphragmatic function like "maximal transdiaphragmatic pressure" measurement and "phrenic nerve stimulation".
Diaphragmatic contraction is controlled by phrenic nerve which consists of anterior rami of 3rd- 5th cervical nerve roots. Usually, It can't be evaluated from history taking and physical examination. Thus the diaphragmatic elevation on chest radiograph is assumed to identify the phrenic nerve dysfunction. Normally, the right diaphragm is higher than the left side about 1.5 ± 0.9 centimeters or 0.5 ± 0.3 time of vertebral height. Although there are several methods to determine the diaphragmatic elevation from previous studies, the accuracy, reliability, intra and inter-observer variation are problem. Neurotization is the effective procedure to restore upper extremity function in root avulsion type. Phrenic nerve is one of the common donor nerves which used for this procedure. But sometimes, concomitant injury of this nerve can occur. Therefore, the investigators established "Diaphragmatic height index (DHI)" from chest radiograph to use as the diagnostic test for phrenic nerve dysfunction.
Peripheral nerve blocks are used to provide post-operative pain relief. Nerve blocks in the neck, in the interscalene area, provide pain relief after shoulder surgery but can cause temporary weakness or paralysis of the diaphragm. The investigators hypothesized that a lower concentration of bupivacaine would cause less weakness of the diaphragm but still provide good pain relief. Lung function and pain control was studied after interscalene peripheral nerve block with 20 milliliters of 0.25% bupivacaine or 0.125% bupivacaine.
Permanent dependency of breathing apparatus due to spinal cord injury is traditionally treated with different types of mechanical ventilation. However, the electric ventilation became a possibility through their most current versions, such as diaphragmatic pacemakers. Diaphragmatic pacemakers rhythmically stimulates the diaphragm to replace the functions of the respiratory center that doesn't works well or is inaccessible. However, this modality has the prerequisite that the phrenic nerve and diaphragm muscle are normal. The reason for the development of diaphragmatic pacemaker freeing the patient from the ventilator. By using the mechanical energy of the diaphragm of the patient, the patient may come not need the ventilator tubing, tracheostomy, and with the help of their caregivers, the inconvenient mechanical ventilators.
This clinical trial is being conducted to study lung function and movement of the major muscle involved in breathing (the diaphragm) after a brachial plexus nerve block (nerve "freezing"). The purpose of this study is to find out what effects (good and bad) ultrasound guided nerve freezing has on the movement of the patient's diaphragm and their lung function. The potential advantage of ultrasound guidance will be a lesser chance of freezing the nerves that innervate the diaphragm and thus having less of an effect on lung function.
