OBJECTIVES: Reductions in diaphragm activity are associated with the postoperative development of atelectasis. Neostigmine reversal is also associated with increased atelectasis. We assessed the effects of neostigmine, sugammadex, and spontaneous reversal on regional lung ventilation and airway flow. METHODS: Six Sprague-Dawley rats were paralysed with rocuronium and mechanically ventilated until recovery of the train-of-four ratio to 0.5. We administered neostigmine (0...

The diaphragm is the muscle most implicated in breathing. Its morphological exploration usually depends on pulmonary radiography, fluoroscopy, CT-scanning and MRI. Its function is evaluated by the classical respiratory functional tests, the measurement of maximum inspiratory and expiratory pressures, the transdiaphragmatic pressure and even an electromyogram. Ultrasound is a technique still insufficiently used in respiratory medicine. It offers, however, many advantages: it is easy to implement, there is no irradiation, it is usable at the bedside, particularly when the patient is immobile or in intensive care...

An eighty-four-year-old man presented with progressive exertional dyspnea, productive cough and weight loss for two months. His physical exam was notable for diminished breath sounds at the right base, with dullness to percussion. Chest-x-ray showed moderate right-sided pleural effusion and bilateral calcified pleural plaques as well as diaphragmatic plaques consistent with asbestos-related pleural disease (ARPD). Pleural fluid was exudative with predominantly mononuclear cells, negative acid fast bacilli stain, negative cultures, and negative cytology for malignant cells...

Kun-Ze Lee, Shih-Hui Hsu
Unilateral high cervical spinal hemisection (i.e., C2Hx) interrupts the respiratory bulbospinal pathway and results in paralysis of the hemidiaphragm. The ipsilateral diaphragmatic activity can partially recover over weeks to months; however, its contribution to the tidal volume generation is less than 20 %. Accordingly, we hypothesized that the contralateral diaphragm exert a compensatory function to maintain the essential ventilation following cervical spinal cord hemisection. The cardiorespiratory pattern and bilateral diaphragm electromyogram (EMG) were measured in urethane-anesthetized and spontaneously breathing adult rats at 1 day, 2 or 8 weeks post-C2Hx or C2 laminectomy...

PURPOSE: Develop a framework for efficient free-breathing simultaneous whole-heart coronary magnetic resonance angiography (CMRA) and cardiac positron emission tomography (PET) on a 3 Tesla PET-MR system. METHODS: An acquisition that enables nonrigid motion correction of both CMRA and PET has been developed. The proposed method estimates translational motion from low-resolution 2D MR image navigators acquired at each heartbeat and 3D nonrigid respiratory motion between different respiratory bins from the CMRA data itself...

Diaphragm flutter is a rare disorder defined by dyspnea and often thoracoabdominal pain associated with rapid rhythmic involuntary contractions of the diaphragm with no effective treatment. A 35-year-old woman's flutter was triggered by increasing the depth of breathing and by (electrical) stimulation of the diaphragm. Medical therapy, phrenic nerve crush, and diaphragm pacer stimulation were ineffective. Since increasing diaphragm activity was a trigger, resting the diaphragm was tried. A manual resuscitator and, subsequently, mouthpiece and nasal noninvasive ventilatory support (NVS) instantaneously halted the flutter for 3 months and almost instantaneously for another 6 months...

Diaphragmatic plication has been a well employed method for the treatment of diaphragmatic eventration and/or paralysis. Uniportal thoracoscopic procedures seem to offer substantial benefit in terms of postoperative pain and cosmesis with similar outcomes as other surgical techniques. A 60-year-old female patient was referred to our clinic for the surgical treatment of diaphragmatic eventration of an unknown cause. The patient was referred to our institution from another hospital, where she had undergone a femoro-popliteal and crural bypass which was unsuccessful, requiring amputation of her leg...

Gastric volvulus is a rare and life-threatening condition that involves the abnormal rotation of the stomach around its axis by more than 180°. The association between acute gastric volvulus and atrial fibrillation with rapid ventricular response is rare with only few cases that have been reported. Our patient was an 86-year-old female who presented with upper abdominal pain, distension, nausea, and shortness of breath. Clinical and laboratory workup revealed acute gastric volvulus with diaphragmatic hernia...

Loutfi S Aboussouan, Eduardo Mireles-Cabodevila
Normal sleep related rapid eye movement sleep atonia, reduced lung volumes, reduced chemosensitivity, and impaired airway dilator activity, become significant vulnerabilities in the setting of neuromuscular disease. In that context, the compounding effects of respiratory muscle weakness and disease-specific features that promote upper airway collapse or cause dilated cardiomyopathy, contribute to various sleep-disordered breathing events. The reduction in lung volumes with neuromuscular disease is further compromised by sleep and the supine position, exaggerating the tendency for upper airway collapse and desaturation with sleep-disordered breathing events...

Ultrasound of the diaphragm in critically ill patients has become a diagnostic technique of emerging interest among clinicians and scientists. The advantages include that it is widely available, non-invasive and examination can be performed after relatively short training and at low costs. It is used to estimate muscle mass by measurement of muscle thickness and diagnose weakness by the assessment of diaphragm movement during unassisted breathing. Thickening of the muscle during inspiration has been used to quantify force generation...

OBJECTIVES: We aimed to develop a more representative model for neonatal congenital diaphragmatic hernia repair in a large animal model, by creating a large defect in a fast-growing pup, using functional pulmonary and diaphragmatic read outs. BACKGROUND: Grafts are increasingly used to repair congenital diaphragmatic hernia with the risk of local complications. Growing animal models have been used to test novel materials. METHODS: 6-week-old rabbits underwent fiberoptic intubation, left subcostal laparotomy and hemi-diaphragmatic excision (either nearly complete (n = 13) or 3*3cm (n = 9)) and primary closure (Gore-Tex patch)...

[Purpose] This study was conducted to investigate the effect of exercise training using transcranial direct current stimulation (tDCS) on breathing in patients with chronic stroke patients. [Subjects and Methods] Thirty chronic stroke patients who do not show abnormal response to electric stimulation were enrolled in this study and each 15 subjects were randomized either into the study group and the sham-controlled group. The subjects performed diaphragmatic breathing exercise for 20 minutes while tDCS device was attached to them (for study group, the device was on while for the sham-controlled group, the device was turned off 30 seconds later) [Results] The results of FVC, FEF1 and FEV1/FVC in the study group and those of FVC and FEV1 in the sham-controlled group were significantly increased after the breathing exercise...

BACKGROUND: To quantify the relationship between regional lung ventilation and coarse aerosol deposition in the supine healthy human lung, we used oxygen-enhanced magnetic resonance imaging and planar gamma scintigraphy in seven subjects. METHODS: Regional ventilation was measured in the supine posture in a 15 mm sagittal slice of the right lung. Deposition was measured by using planar gamma scintigraphy (coronal scans, 40 cm FOV) immediately postdeposition, 1 hour 30 minutes and 22 hours after deposition of (99m)Tc-labeled particles (4...

Forces involved in breathing-which effectively pull in air-are the diaphragmatic, intercostal, spine, and neck muscles. Equally important is the bulbar musculature maintaining the architecture of a patent airway conduit and abdominal wall and internal intercostal muscles providing cough. Acute injury along a neural trajectory from brainstem to muscle will impair the coordinated interaction between these muscle groups. Acutely failing respiratory mechanics can be caused by central and peripheral lesions. In central lesions, the key lesion is in the nucleus ambiguus innervating the dilator muscles of the soft palate, pharynx, and larynx, but abnormal respiratory mechanics rarely coincide with abnormalities of the respiratory pattern generator...
