Of 1225 patients undergoing open heart surgery over an 18-month period, 13 had diaphragmatic dysfunction due to phrenic nerve injury; 11 of these had internal mammary artery grafting. Nine had diaphragmatic dysfunction on the same side as the internal mammary artery graft side (7 bilateral and 2 unilateral) as determined by fluoroscopy during phrenic nerve stimulation. Although topical cardiac hypothermia has been the prevailing mechanism for diaphragmatic dysfunction due to phrenic nerve injury after open-heart surgery, dissection of the internal mammary artery with electrocautery, traction, or vascular compromise to the phrenic nerve, or a combination, could be additional factors. Rocking bed ventilation was instituted to facilitate passive diaphragmatic movement and airway decannulation and was continued at home until the phrenic nerve or nerves recovered. These patients were followed up clinically and with serial measurements of vital capacity, respiratory muscle strength, phrenic nerve ...
The subject of ventilator-induced diaphragmatic dysfunction is important because hundreds of thousands of patients receive prolonged mechanical ventilation in intensive care units (ICUs). Many of these patients require difficult and prolonged weaning, accounting for 40% to 60% of the total time on mechanical ventilation. Difficulty weaning from ventilation increases ICU stay and health care costs. There is some evidence that ventilator-induced diaphragmatic dysfunction may develop after 6 hours or less of mechanical ventilation. If so, then patients undergoing long surgeries might be at risk. Perhaps subsets of patients undergoing cancer resection, trauma reconstruction, or complex cardiovascular operations bear a higher inflammatory burden from ventilator-induced diaphragmatic dysfunction.. Ventilator-induced diaphragmatic dysfunction is multifactorial. Diaphragm inactivity is obviously one major contributor. In this issue of Anesthesia & Analgesia, Breuer et al.1 present evidence that ...

Alterations to the supply of oxygen during early life presents a profound stressor to physiological systems with aberrant remodeling that is often long-lasting. Chronic intermittent hypoxia (CIH) is a feature of apnea of prematurity, chronic lung disease and sleep apnea. CIH affects respiratory control but there is a dearth of information concerning the effects of CIH on respiratory muscles, including the diaphragm - the major pump muscle of breathing. We investigated the effects of exposure to gestational CIH (gCIH) and postnatal CIH (pCIH) on diaphragm muscle function in male and female rats. CIH consisted of exposure in environmental chambers to 90s of hypoxia reaching 5% O2 at nadir, once every 5 min, 8 hrs a day. Exposure to gCIH started within 24 hours of identification of a copulation plug and continued until day 20 of gestation; animals were studied on postnatal day 22 or 42. For pCIH, pups were born in normoxia and within 24h of delivery were exposed with dams to CIH for 3 weeks; animals were
PURPOSE OF REVIEW: It has become clear from experimental data that prolonged mechanical ventilation can induce diaphragm dysfunction, also known as ventilator-induced diaphragm dysfunction. In this article we will discuss most recent understanding on
BACKGROUND: Lung volume reduction (LVR) has recently been used to treat severe emphysema. About 25% of the volume of each lung is removed with this method. Little is known about the mechanism of functional improvement so a study was undertaken to investigate the changes in ventilatory mechanics and diaphragmatic function in eight patients after LVR. METHODS: Measurements of work of breathing (WOB), intrinsic positive end expiratory pressure (PEEPi), dynamic compliance (Cdyn), and arterial carbon dioxide tension (PaCO2) were performed on the day before surgery and daily for seven days after surgery, as well as one, three, and six months after surgery. All measurements were performed on spontaneously breathing patients, simultaneously assessing oesophageal pressure via an oesophageal balloon catheter and air flow via a tightly adjusted mask. Diaphragmatic function was evaluated by measuring oesophageal and transdiaphragmatic pressure (Pdi) preoperatively and at one, three, and six months ...
The bilateral diaphragm is the most important respiratory muscle. Diaphragmatic dysfunction is an underappreciated cause of respiratory difficulties and may be due to a wide variety of issues, including surgery, trauma, tumor, and infection (1). Several previous studies have evaluated diaphragmatic motion using fluoroscopy 2; 3; 4 ; 5, ultrasound 6 ; 7, magnetic resonance (MR) fluoroscopy (dynamic MR imaging [MRI]) 8; 9; 10; 11 ; 12, and computed tomography (CT) 13; 14; 15 ; 16. However, the data of the previous studies using ultrasound, MR fluoroscopy, or CT were obtained in a supine position 6; 7; 8; 9; 10; 11; 12; 13; 14; 15 ; 16, not in a standing position. Also, while the data of the previous studies using fluoroscopy were obtained in a standing position, the data were assessed under forced breathing 2 ; 3, not under tidal or resting breathing. Thus, diaphragmatic motion in a standing position during tidal breathing remains unclear, even though it is ...

AU - Dempsey, J. A.. PY - 1995. Y1 - 1995. N2 - We examined the effects of hypoxia on exercise-induced diaphragmatic fatigue. Eleven subjects with a mean maximal O2 uptake of 52.4 ± 0.7 ml. kg-1 · min-1 completed one normoxic (arterial O2 saturation 96-94%) and one hypoxic (inspiratory O2 fraction = 0.15; arterial O2 saturation 83- 77%) exercise test at 85% maximal O2 uptake to exhaustion on separate days. Supramaximal bilateral phrenic nerve stimulation (BPNS) was used to determine the pressure generation of the diaphragm pre- and postexercise at 1, 10, and 20 Hz. There was increased flow limitation during hypoxic vs. normoxic exercise. There was a decrease in hypoxic exercise time (normoxic 24.9 ± 0.7 min vs. hypoxic 15.8 ± 0.8 min; P , 0.05). After exercise the BPNS transdiaphragmatic ...
Traumatic diaphragmatic ruptures affect mainly the left side. In an experimental study in human corpses we examined the stretch behaviour of the left and right diaphragmatic halves. In a total of 8 male and 8 female corpses each diaphragmatic half was divided into 4 different segments. Each segments stretch behaviour was investigated. In steps of 2 N the stretch was increased up to 24 N. In the female the left diaphragm showed a stronger elasticity compared to the right. Additionally the left diaphragm in females showed a higher elasticity in comparison to the left in males. Traumatic diaphragmatic ruptures affect mostly the central tendineous part or the junction between tendineous and muscular part of the diaphragmatic muscle. Accordingly we found a lower elasticity in these parts compared with the other diaphragmatic segments. In summary it can be said that albeit some restrictions we were able to determine the elasticity of different diaphragmatic segments quantitatively and reproduceably with our

Mitochondria are fascinating organelles regulating many critical cellular processes for skeletal muscle physiology. Indeed, they play central roles in muscle cell metabolism, energy supply, the regulation of energy-sensitive signaling pathways, reactive oxygen species (ROS) production/signaling, calcium homeostasis and the regulation of apoptosis [1]. Given these multifaceted roles of mitochondria in fundamental aspects of skeletal muscle cell physiology, it is not surprising that mitochondrial dysfunction has been implicated in a large number of adverse conditions affecting skeletal muscle health. This includes for instance the aging-related loss of muscle mass and function [2-9], disuse-induced muscle atrophy [10], ventilator-induced diaphragmatic dysfunction [11], Duchenne and collagen muscular dystrophies [12, 13], long-term muscle dysfunction induced by chemotherapy treatment [14, 15], and the development of insulin resistance [16]. While the importance of normal mitochondrial function is well
Our study demonstrated that the average excursions of the bilateral tsh receptor during tidal breathing (right: 11.0 mm, 95% CI 10.4 to 11.6 mm; left: 14.9 mm, 95% CI 14.2 to 15.5 mm) were numerically less than those during forced breathing in previous studies using other modalities 2; 7 ; 8. Using fluoroscopy, Alexander reported that the average right excursion was 27.5 mm and the average left excursion was 31.5 mm during forced breathing in the standing position in 127 patients (2). Using ultrasound, Harris et al. reported that the average right diaphragm excursion was 48 mm during forced breathing in the supine position in 53 healthy adults (7). Using MR fluoroscopy, Gierada et al. reported that the average right excursion was 44 mm and the average left excursion was 42 mm during forced breathing in the supine position in 10 healthy volunteers (8). The difference in diaphragmatic excursion during tidal breathing versus forced breathing is unsurprising ...

TY - THES. T1 - The function of the human diaphragm as a volume pump and measurement of its efficiency. AU - Singh, Bhajan. PY - 2003. Y1 - 2003. N2 - [Truncated abstract] The function of the diaphragm as a volume pump has not been adequately evaluated because there are no accurate methods to measure the volume displaced by diaphragm motion (ΔVdi). As a consequence, the work done, power output and efficiency of the diaphragm have not been measured. Efficiency of the diaphragm could be measured by relating the power output of the diaphragm to its neural activation. The aims of this thesis were to (a) develop a new biplanar radiographic method to measure ΔVdi and use this to evaluate the effect of costophrenic fibrosis and emphysema on ΔVdi, (b) develop a new fluoroscopic method to enable breath-by-breath measurements of ΔVdi, (c) evaluate a method for quantifying neural activation of the diaphragm, and (d) combine measurements of transdiaphragmatic pressure, ΔVdi, inspiratory duration and ...
Concentrations of spermidine, spermine and putrescine have been measured in rat diaphragm muscle after unilateral nerve section. The concentration of putrescine increased approx. 10-fold 2 days after nerve section, that of spermidine about 3-fold by day 3, whereas an increase in the concentration of spermine was only observed after 7-10 days. It was not possible to show enhanced uptake of either exogenous putrescine or spermidine by the isolated tissue during the hypertrophy. Consistent with the accumulation of putrescine, activity of ornithine decarboxylase increased within 1 day of nerve section, was maximally elevated by the second day and then declined. Synthesis of spermidine from [14C]putrescine and either methionine or S-adenosylmethionine bt diaphragm cytosol rose within 1 day of nerve section, but by day 3 had returned to normal or below normal values. Activity of adenosylmethionine decarboxylase similarly increased within 1 day of nerve section, but by day 3 had declined to below ...
Zone of apposition (ZOA). The zone of apposition makes up a substantial but varying area of the ribcage. In standing at rest the human ZOA represents about 30% of the total surface area of the inner ribcage (11). The crural part of the diaphragm peels away from the ribcage at the zone of apposition (10) (9) (12) during diaphragm contraction to allow the diaphragm to descend during inspiration. The zone of apposition decreases by about 15mm during quiet inspiration while the dome of the diaphragm almost remains constant in shape and size. At maximum inspiratory capacity of the lungs the ZOA is almost zero. The shortening of the apposed muscle fibres are mainly responsible for the diaphragms axial displacement during inspiration (2) (6). A smaller zone of apposition will result in reduced inspiratory action of the diaphragm on the ribcage (9).. 4. ...
Studies performed in the past 10 years indicate that many mechanically ventilated MICU patients have severe diaphragm weakness [1-5]. Moreover, diaphragm weakness is thought to be associated with poor outcomes in this patient population, with the weakest patients requiring more prolonged mechanical ventilation and having a significantly higher mortality than patients with better diaphragm strength [1, 4]. Because of this evidence, it is speculated that mechanically ventilated patients may benefit from treatment with anabolic agents which increase skeletal muscle strength. In theory, such agents could improve patient outcomes, reducing duration of mechanical ventilation and patient mortality. Several pharmacological agents have been shown to improve skeletal muscle strength in other patient populations (e.g., the elderly, patients with cancer, patients with chronic obstructive pulmonary disease, COPD) and it is reasonable to believe that one or more of these agents may also be capable of ...

N2 - Interactive effects of emphysema (EMP) and prolonged nutritional deprivation (ND) on contractile, morphometric, and metabolic properties of hamster diaphragm muscle (DIA) were examined. Six months after induction of EMP (intratracheal elastase), saline-treated controls (CTL) and EMP hamsters of similar body weights were subjected to ND over 6 wk. Isometric contractile and fatigue properties of costal DIA were determined in vitro. DIA fibers were histochemically classified as type I or II, and fiber succinate dehydrogenase activity and cross-sectional area were determined using quantitative microscopic procedures. From histochemical sections, the number of capillaries per fiber (C/F) and per fiber cross-sectional area (C/A) were determined. ND resulted in progressive loss of body weight (ND-CTL, ...

The use of ultrasonography has become increasingly popular in the everyday management of critically ill patients. It has been demonstrated to be a safe and handy bedside tool that allows rapid hemodynamic assessment and visualization of the thoracic, abdominal and major vessels structures. More recently, M-mode ultrasonography has been used in the assessment of diaphragm kinetics. Ultrasounds provide a simple, non-invasive method of quantifying diaphragmatic movement in a variety of normal and pathological conditions. Ultrasonography can assess the characteristics of diaphragmatic movement such as amplitude, force and velocity of contraction, special patterns of motion and changes in diaphragmatic thickness during inspiration. These sonographic diaphragmatic parameters can provide valuable information in the assessment and follow up of patients with diaphragmatic weakness or paralysis, in terms of patient-ventilator interactions during controlled or assisted modalities of mechanical ventilation, ...
In the current study, we used an experimental model of compensated cardiac hypertrophy induced by pressure overload over a 12-week period. The degree of hypertrophy induced in our study (136 ± 21%) was consistent with previous studies using the same model and reported a mean cardiac hypertrophy of 127%11 and 136%. 32 These authors reported noncardiac abnormalities associated with cardiac hypertrophy, including skeletal and diaphragmatic muscle abnormalities, without any physical signs of congestive heart failure, but they did not perform accurate evaluation of myocardial performance. 11 Our results showed a preserved state of contractility as indicated by the absence of significant difference in indexed Emaxbetween SHAM and LVH groups but an alteration of the diastolic compliance in the LVH group (fig. 1). These results explain significant differences in the inotropic and lusitropic baseline values between SHAM and LVH1groups. In the latter group, by altered diastolic compliance, the value of ...

Though most amino acids are oxidized during the liver, BCAAs are mainly oxidized within the skeletal muscle mass together with other peripheral tissues.[four] The effects of BCAA administration on muscle mass expansion in rat diaphragm эта модель proteinkievua was examined, and concluded that not simply does a mixture of BCAAs by yourself possess the similar effect on advancement as a complete combination of amino acids, but an amino acid mixture with all but BCAAs has no impact on rat diaphragm muscle advancement.[17] Administration of both isoleucine or valine alone had no effect on muscle mass development, Even though administration of leucine on your own seems for being just about as efficient as the entire combination of BCAAs. Leucine indirectly activates p70 S6 kinase and also stimulates assembly with the eIF4F elaborate, that are essential for mRNA binding in translational initiation ...

Diaphragm. A dome-shaped muscle that separates the abdominal cavity from the thoracic cavity. The origin of the muscles of the diaphragm is along the internal circumference of the ribcage, sternum, and lumbar vertebrae. This portion of muscle consists of the esophageal hiatus, at the T10 vertebral level, and the aortic hiatus, at the T12 vertebral level. The muscle fibers are directed to the center of the diaphragm, to the central tendon. The central tendon consists of collagen tissue and the venal caval hiatus, which is at the T8 vertebral level. When the muscle is stimulated to contract (phrenic nerve, C1-C4), the muscle fibers shorten, causing the central tendon to move inferiorly and flatten. This action results in inspiration. The structural components of the diaphragm are as follows ...

Moderate correlations established between diaphragm thickness and strength (r=0.52; r2=0.27; p<0.001); and thickness and BMI (r=0.57; r2=0.33; p<0.001). Weak correlation established between strength and BMI (r=0.37; r2=0.14; p=0.01). Endurance was not correlated to thickness (r=-0.15; r2=0.02; p=0.29), or strength (r=-0.19; r2=0.04; p=0.16). Conclusion: The results indicate that in a volunteer university student population diaphragm thickness is moderately correlated to strength but not to endurance. BMI is a potential confounder when investigating the relationship between strength and thickness. Further studies are needed to confirm these results in a wider population. ...

The diaphragm (dia: across, phragm: fence) is the musculotendinous, dome-shaped structure separating the negative-pressure thoracic cavity and the positive-pressure peritoneal cavity. Embryologically, the diaphragm is derived from the fusion of four distinct structures: the septum transversum, the pleuroperitoneal membranes, the dorsal mesentery of the esophagus, and the body wall musculature. After development is complete, the diaphragm is composed of two distinct muscle groups, costal and crural. The costal muscle group is composed of peripherally located skeletal muscle fibers, whose contraction results in flattening of the diaphragm and lowering of the ribs. The crural muscle group, by contrast, does not contribute significantly to diaphragmatic excursion. The left crus arises from the upper two lumbar vertebrae and the right crus arises from the lateral aspect of the upper three lumbar vertebrae. The interdigitation of the medial tendinous crural fibers anterior to the aortic hiatus forms ...

The Fink article stimulated subsequent studies in humans7,8 and animals8 using indwelling Pao2electrodes, which did detect a modest "diffusion effect." The various authors emphasized its contribution to hypoxemia developing in the emergence period of anesthesia.7,8 As measurement of arterial blood gases and other modalities of lung function such as imaging, diaphragmatic function, and lung volume became clinically available, the original concept of diffusion anoxia has faded into that of a historical footnote. Alveolar collapse or atelectasis due to a variety of causes during emergence from anesthesia9 has been recognized as the major contributor to the hypoxemia or "cyanosis" observed by early practitioners of our specialty. Ray Fink did note that lung volume and ventilatory status contributed to diffusion anoxia, but he did not recognize their major contribution to emergence hypoxemia. The original "evidence" for the need for a higher inspired concentration in the patient emerging from ...
1. Deep abdominal breathing practice. Enhancing diaphragm function is a major skill to improve. Two big things with diaphragm strengthening: 1) You will take in oxygen more efficiently and 2) It will increase thoracic spine (12 mid-spine vertebrae) function. It can open up many pathways to better movement and coordination. Simply lie on your back, bend your knees, and place one had on your belly button and one hand on your chest. When exhaling, push strong air through your stomach first (your bottom hand will rise), trying to expand out and to the sides of your "ab wall"; and then allow air to flow to the chest. You do not want your shoulders shrugging when breathing. Perform 5-15 deep breaths a few times during the day. ...
Rebekah is only assisted with 2 litres of 02 which isnt much at all but gives her the boost she needs. She may have to come home with this assistance for some time. Also, her diaphragm function is a big part of this current battle that is keeping us here now. Recent reports had indicated that this was improving, but those indications at best are very slight. Because the diaphragm (the largest and most blood-nourished muscle that never sleeps) is huge in assisting breathing deeply, allowing the lower part of the lungs to draw in sufficient air to sustain the body and blow off blood gasses and lower acidic levels in the body, is barely working and not assisting as it should, we have seen Rebekahs CO2 rising once again throughout the day and even more rapidly as she sleeps.
