Bronchial suction does not facilitate lung collapse when using a double-lumen tube during video-assisted thoracoscopic surgery: a randomized controlled trial
Atelectasis refers to collapse of part of the lung. It may include a lung subsegment or the entire lung and is almost always a secondary phenomenon, with no sex or race proclivities; however, it may occur more frequently in younger children than in older children and adolescents.
RPE was first described by Pinault in 1853, after the removal of pleural fluid.2 Since then many cases have been reported in the literature, describing reexpansion of the collapsed lung following drainage of fluid or air. The incidence of RPE following pleural effusion or pneumothorax is between 0 and 1%.3 Risk factors for development of RPE include duration of lung collapse , 3 days, removal of over 2,000 mL of fluid, age in the fourth decade of life, and an onset within 24 hours from reexpansion of the collapsed lung.1. The etiology of RPE is not fully appreciated. Current evidence suggests RPE is the result of increased permeability of the pulmonary capillaries due to alterations in lymph flow, protein concentration, and colloid pressure following reexpansion. Koike et al, in their study with 14 unanaesthetized sheep, demonstrated increased caudal mediastinal lymph flow post reexpansion after 24 hours of lung collapse.4 Clinical studies by Buczko et al and Sprung et al measured protein ...
It is not going to be a nice experience when your lung collapse. Pneumothorax happens when your lung collapse and you will get severe chest pain and breathing difficulties. When that happens, a tube will have to be inserted into the affected lung to drain away the air leakage. That will require a few days of hospitalisation. Anyway if I were to do the lung biopsy, I need to be hospitalised for one night to let them monitor me after the biopsy...because there is a risk of pneumothorax. Its not safe to return home after the lung biopsy because you never know if you will get it. Not only that, the lung biopsy will be performed guided by a CT scan. This means I will be exposed to radiation again. CT scan radiation is 500 times the radiation of a normal x-ray. Ok, that is even worse ...

Endotracheal tube (ETT) cuff herniation is a rare, and often difficult to diagnose, cause of bronchial obstruction. We present a case of outside cuff herniation of an endotracheal tube that caused pulmonary right lung atelectasis. A 29-year-old man ,a case of car accident with multiple fractures, was admitted to the emergency ward and transferred to the operating room(OR) for open reduction and internal fixation (ORIF) of all fractures .The procedures were done under general anesthesia (G/A). The past medical history of the patient did not indicate any problem. Anesthesia was induced with thiopental, atracurium and then maintained by propofol and remifentanyl infusions and 100% O2 via orally inserted ETT. The patient was positioned in left lateral decubitus position for operation. Two hours after induction of anesthesia, the oxygen saturation level dropped to 85 % and the breath sounds in the right side of the chest were weakened. The chest x-ray images showed right lung atelectasis especially ...
If left untreated, atelectasis may be fatal in patients and progress to pneumonia, sepsis, and respiratory failure. Common complications of atelectasis include pneumonia, bronchiectasis, hypoxemia, respiratory failure, and sepsis. Depending on the extent of lung involvement at the time of diagnosis, the prognosis may vary. However, the prognosis is generally regarded as good. Involvement of a small portion of the lung is not associated with life threatening complications, as the remaining lung compensates for the hypoxemia. However, atelectasis is associated with poor prognosis if the surface area of lung involvement is very large, in the presence of pre-existing lung disease, in case of failure to remove obstruction and in case of atelectasis due to cancer. ...

A close study of postoperative massive collapse of the lung (pulmonary atelectasis) indicates its marked similarity to pneumonia. These two conditions have many characteristics in common and, from the study of atelectasis, we may draw certain deductions relative to pneumonia.. As observed by Norris and Landis,1 "practically every case of pneumonia spreads to some extent. In some cases it slowly extends spreading from lobe to lobe by contiguity; in others the process apparently develops afresh at different points in the same or the opposite lung", and, "in double pneumonia, both bases may be affected simultaneously or the apex of one ...
Atelectasis: Collapse or loss of lung volume May involve entire lung, a lobe, a segment, or be subsegmental There are 5 mechanisms of atelectasis: 1) (Post) obstructive 2-5) Non-obstructive - typically due to loss of contact between parietal and visceral pleura. This presentation will cover the 5 mechanisms of atelectasis, as well as radiographic findings of collapse in all 5 lung lobes.

The study had purpose to evaluate the possible electrocardiographical alterations and the histopathological alterations in the lung of dogs submited by left pneumonectomy with comparative approach between two types of suture of bronchial stamp (manual and mechanical). We used twelve dogs, males and females, adults, mongrel dogs, weighting between 15 and 20 kilograms and evaluated the macroscopic alterations of right lung and the alterations of electrocardiogram. All animals showed clinical condition satisfactory in the post operated time. The electrocardiographical alterations were deviation of cardiac axis, sinoatrial block and miocardial isquemia. The histopathological alterations were pulmonary atelectasis, proliferations of bronchiole epithelium tended to obliterations and pulmonary emphysema. The study suggested that right lung was submited to pulmonary hipertension ...

Although the sine qua non of atelectasis is the loss of volume of lung tissue, whether the entire lung, lobar, segmental or subsegmental, a myriad of pathologic factors may induce the same result.1 Resorptive atelectasis is due to endobronchial obstruction, intralumenally as by a tumor or mucus plug or by extrinsic bronchial compression, as in lymphadenopathy.2 Passive atelectasis is caused by parenchymal compression extrinsic to the lung tissue, such as a pleural effusion, pneumothorax, or hypovenilation, while an intraparenchymal mass may, itself, result in compressive atelectasis of an adjacent region of lung. Finally, interstitial fibrosis of any source leads to a loss of lung volume known as cicatrizing atelectasis 3 Acute, obstructive atelectasis often leads to sudden respiratory distress, but insidious pulmonary volume loss may be asymptomatic.1 Therefore, radiology plays a key role in detecting the presence, location and possible source of atelectasis. Plain film radiography provides a ...

Treatment is directed at correcting the underlying cause. Post-surgical atelectasis is treated by physiotherapy, focusing on deep breathing and encouraging coughing. An incentive spirometer is often used as part of the breathing exercises. Walking is also highly encouraged to improve lung inflation. People with chest deformities or neurologic conditions that cause shallow breathing for long periods may benefit from mechanical devices that assist their breathing. One method is continuous positive airway pressure, which delivers pressurized air or oxygen through a nose or face mask to help ensure that the alveoli do not collapse, even at the end of a breath. This is helpful, as partially inflated alveoli can be expanded more easily than collapsed alveoli. Sometimes additional respiratory support is needed with a mechanical ventilator.. The primary treatment for acute massive atelectasis is correction of the underlying cause. A blockage that cannot be removed by coughing or by suctioning the ...
The term atelectasis, which is defined as diminished lung volume, is derived from the Greek words ateles and ektasis, which mean incomplete expansion (see the image below). Atelectasis may affect all or part of a lung, and it is one of the most common radiographic abnormalities.
Atelectasis is the collapse of one or more sections, or lobes, of the lungs. When you breathe in, the lungs normally expand to fill with air. With atelectasis, a blockage in or pressure in the area around the lung (pleura) keeps the lung from expanding.

We develop tidal-ventilation pulmonary gas-exchange equations that allow pulmonary shunt to have different values during expiration and inspiration, in accordance with lung collapse and recruitment during lung dysfunction (Am. J. Respir. Crit. Care Med. 158 (1998) 1636). Their solutions are tested against published animal data from intravascular oxygen tension and saturation sensors. These equations provide one explanation for (i) observed physiological phenomena, such as within-breath fluctuations in arterial oxygen saturation and blood-gas tension; and (ii) conventional (time averaged) blood-gas sample oxygen tensions. We suggest that tidal-ventilation models are needed to describe within-breath fluctuations in arterial oxygen saturation and blood-gas tension in acute respiratory distress syndrome (ARDS) subjects. Both the amplitude of these oxygen saturation and tension fluctuations, and the mean oxygen blood-gas values, are affected by physiological variables such as inspired oxygen concentration,
The global endotracheal tube is expected to exhibit a CAGR exceeding 12.5% and reach around USD 312 million by 2018. The endotracheal tubes (ETTs) are flexible plastic tubes that are inserted in the mouth and down the airway or trachea. This device is used to maintain an open airway and assist in the delivery of anesthetic gas, medicine, or oxygen to the patient.. The ETTs support the patients to breathing during heart failure, collapsed lung, pneumonia, and emphysema. It also protects the lungs for patients who are at a risk of breathing in fluids and are unable to protect their airway. For instance people suffering from overdose, strokes, or bleeding from the stomach or esophagus..

BACKGROUND Chest physiotherapy (CPT) has been used in many neonatal nurseries around the world to improve airway clearance and treat lung collapse; however, the evidence to support its use has been conflicting. Despite the large number of studies there is very little evidence of sufficiently good quality on which to base current practice. OBJECTIVES To assess the effects of active CPT techniques, such as percussion and vibration followed by suction compared with suction alone, on the respiratory system in infants receiving mechanical ventilation. Additionally, differences between types of active CPT techniques were assessed. SEARCH STRATEGY Our search included The Cochrane Library (Issue 2, 2007), MEDLINE (1966 to 2007), EMBASE (1988 to 2007), CINAHL, Science Citation Index, previous reviews including cross-references, abstracts, conference proceedings and grey literature. SELECTION CRITERIA Trials in which ventilated newborn infants up to four weeks of age were randomly or quasi-randomly assigned
TUESDAY, Dec. 17, 2019 (HealthDay News) -- Nikki Moreno had spent nearly a year struggling for breath, and nothing seemed to help.. Not the inhalers, not the antibiotics and other drugs. Nothing seemed to help her breathe, and nothing got rid of her constant cough.. It finally got so bad that she landed in the emergency room at UCLA Medical Center in Santa Monica.. Moreno was not prepared for the series of shocks that followed.. First, doctors told her that her left lung had completely collapsed. Then Moreno underwent a bronchoscopy that revealed the reason for her lung collapse -- a 2-centimeter tumor had blocked the airway.. Doctors diagnosed her with stage 4 lung cancer, and told her the cancer had spread to her brain, spine, kidney and pancreas.. Moreno had never smoked. Shed never lived with anyone who smoked. The most exposure to secondhand smoke shed ever experienced was at outdoor concerts.. "I was completely shocked," said Moreno, 43, a bookkeeper living in Los Angeles. "That was not ...
Together, these studies provide evidence that exposure to diabetes in utero may have adverse effects on an infants lung development, including delayed lung maturation and an increased risk for a condition known as respiratory distress syndrome (RDS). RDS is a breathing disorder in which the air sacs (alveoli) in a newborns lungs collapse because the production of a substance that coats the alveoli (surfactant) is absent or insufficient.. According to lead author Dr. Meghan Azad, a Research Scientist at the Childrens Hospital Research Institute of Manitoba, a potential mechanism for the association between diabetes in pregnancy and infant RDS is related to high circulating levels of glucose in the diabetic mother.. "From the studies we reviewed, it appears that newborns who were exposed to hyperglycemia in utero may have impaired production of surfactant proteins that are important for proper lung function," said Dr. Azad, who is also an assistant professor in Pediatrics & Child Health at the ...
Summary Sir, this patient has a pleural effusion. On examination of the chest, there is reduced chest expansion on the right side. The percussion note is stony dull, and there is reduced air entry and vocal resonance for one half of the posterior hemithorax. The patient is not in respiratory distress, and the trachea is central. With regards to underlying aetiology, there is no palpable lymphadenopathy, clubbing or tar staining of the fingers to suggest a mitotic process. I would like to measure the patients temperature to look for evidence of infection, although there are no crepitations to suggest this. There is no arthropathy or rash which would suggest underlying autoimmune disease. Possible differential diagnoses for dullness with reduced air entry include pleural thickening, asbestos-related pleural disease, primary mitotic processes of the pleura, lung collapse - although I would expect tracheal deviation towards the affected side, consolidation and previous lobectomy / pneumonectomy - ...
These findings are being published in the July 6, 2010, edition of the journal CHEST.. LAM is a rare but serious lung disease that affects women, causing shortness of breath and lung collapse, called a pneumothorax. The disease occurs when an unusual type of cell invades the lungs and causes tissue destruction by creating holes or cysts in the lung. It can be fatal.. Lisa Young, MD, lead author on the study and researcher at UC and Cincinnati Childrens, says that these findings will help with diagnosing LAM and may also be helpful in screening for LAM in women with Tuberous Sclerosis Complex (TSC), a genetic disorder that causes tumors to form in many different organs. TSC is a risk factor for the development of LAM.. In this study, the test was used to analyze the amount of a specific protein-vascular endothelial growth factor-D, or VEGF-D-in patients blood. VEGF-D promotes the growth of lymphatic vessels and blood vessels and can be involved in the spread of cancer.. Researchers performed ...
Our results suggest that in ventilated pediatric patients with ALI: both SI and SRS effectively raise PaO2 and FRC; SI may be associated with temporary desaturation in children; SRS is associated with an increase in PaCO2 during the maneuver; and both SI and SRS are hemodynamically well tolerated.. Several studies have noted that both SI and SRS are effective in raising PaO2 in adults and children with ARDS.7,11,13,23 When an SRS was applied following an SI, in non-randomized fashion, Borges et al11 noted that PaO2 rose further following SRS. When assessed using computed tomography, Borges et al also noted regions of lung collapse that had not opened following SI became aerated following SRS. This is consistent with the increase in FRC we demonstrated following SRS, compared to following SI. However, in both the Borges et al study and our study, the non-randomized, sequential application of SRS after an SI precludes any conclusions regarding the efficacy of one maneuver over the other; it is ...
The definition of a pneumothorax is an accumulation of air outside the lungs, but inside the chest wall. The air outside the lung prevents the lungs from inflating normally, and can lead to lung collapse. There are several variations of pneumothorax. ...
Adaptation to respiration at birth depends upon the synthesis of pulmonary surfactant, a lipid-protein complex that reduces surface tension at the air-liquid interface in the alveoli and prevents lung collapse during the ventilatory cycle. Herein, we demonstrated that the gene encoding a subunit of the endoplasmic reticulum membrane complex, EMC3, also known as TMEM111 (Emc3/Tmem111), was required for murine pulmonary surfactant synthesis and lung function at birth. Conditional deletion of Emc3 in murine embryonic lung epithelial cells disrupted the synthesis and packaging of surfactant lipids and proteins, impaired the formation of lamellar bodies, and induced the unfolded protein response in alveolar type 2 (AT2) cells. EMC3 was essential for the processing and routing of surfactant proteins, SP-B and SP-C, and the biogenesis of the phospholipid transport protein ABCA3. Transcriptomic, lipidomic, and proteomic analyses demonstrated that EMC3 coordinates the assembly of lipids and proteins in ...

At age 13 my asthma which Id suffered from since age 18mths seemed to become uncontrollable. I spent most of my early teens on the childrens ward at a local hospital, where doctors prescribed every asthma medication they could think of with no success, during that time I suffered chest infections every 6wks and experienced my first lung collapse. Eventually after a year of trials with different asthma medications a CT Scan of my lungs was carried out. My doctor at first blamed the CT Scanner for distorting the images and asked for a repeat scan. This confirmed their worst fears, there was a reason asthma medication wasnt working that was because I had a lung disease called interstitial lung disease (ILD) which is progressive, irreversible and eventually fatal. No sooner were the reports in I was transferred to a specialist childrens hospital, they found I had a massive pneumonia and already had large amounts of permanent lung damage. It took 3mths in critical care for me to recover enough ...
The bacterial form of pneumonia occurs when the responsible organism enters the lower respiratory tract, primarily through inhalation or choking, but an organism can also enter the body through the bloodstream. The body responds severely with bronchitis, swelling, lack of blood supply, tissue death, abscess formation, and even lung collapse. If the animal has a poor immune system, then even bacteria that are normally present in the mouth, throat and lungs can become infectious. Due to all of this, there may be very low levels of oxygen available in the blood.. Fungal infections usually occur when the spores are inhaled, entering the lung (and sometimes the bloodstream). This triggers the rabbits immune system to send white blood cells to fight the invading organism. These cells are then intercepted and engulfed by the organisms, releasing a chemical (cytokine) which impairs oxygen distribution in the lungs.. Viral infections occur in much the same way, except it is the virus which enters the ...
Lung cancer is by far the most common disease for long-term somkers. Other common cancers include mouth, larynx, tongue and skin. Later research has shown that kidney, bladder, cervix and breast cancers are also common with long-term smokers. COPD stands for Chronic Obstructive Pulmonary Disease, which ranges from a very mild case of bronchitis, to more severe cases. Emphysema is were the air sacs in your lungs collapse and theres nowhere for the oxygen to come and go. This ends with a person basically smothering to death. More less serious effects include permanent nasal congestion, coughing, vision problems, gum disease. ...
BPT) - Working mom Betsy had a fulfilling career and a loving family. The only thing standing in the way of her ability to fully enjoy her life was a persistent cough that just wouldnt stop. Eventually, instead of doing the things she enjoyed, like spending time with her twin boys or going to dinner with friends, her life became something else entirely. That nagging cough - over and over again - coupled with difficulty breathing and fatigue made her feel weaker and weaker.. Betsy had a history of spontaneous lung collapses and a cough that would come and go, but her symptoms gradually became worse and began to impact her life. After a visit to her doctor, Betsy was diagnosed with bronchitis and given remedies to soothe her coughing. When weeks passed and she saw no improvement to her health, she knew she had to find answers.. I tried to read my boys books at night and it was a real struggle just to get through the book without coughing… Not knowing what was happening to me, nobody being able ...

Discussion. Table of Contents Answer: Eosinophilic pneumonia, bland pulmonary infarcts, rounded atelectasis, cryptogenic organizing pneumonia, and usual interstitial pneumonia all classically are most prominent at the lung periphery [1,2]. Pulmonary alveolar edema and Kaposis sarcoma may affect the entire lung, but are often more central (perihilar) in location [1,3]. Kaposis sarcoma also has a basilar predominance. Cryptogenic organizing pneumonia appears radiographically as large foci of non-segmental, patchy consolidation [4]. The distribution is diffuse but with a basilar predominance and a peripheral location (often best seen on CT). The consolidations may wax and wane, but rarely cavitate. The most common HRCT findings are patchy consolidation and ground-glass opacity seen in a peribronchial and peripheral location [5]. In regions of abnormal lung, the bronchial walls are usually thickened, and lumens may be dilated. Less commonly, ill-defined peribronchovascular nodules or small ...
Secondly, the degree to which the Ppl rises - in response to mechanical insufflation of the thorax - mediates RV preload. As such, a stiffened chest wall will increase Ppl for any given volume on the y-axis, dropping RV preload more impressively - see figure 3.. Implications for Practice. Thus, the clinician must recognize and balance the pre- and afterload effects exerted upon the RV by the respiratory pump [9]. Aim to minimize the area between the respiratory system compliance curve and the chest wall compliance curve; this should reduce Ptp and, ostensibly, RV afterload. Selective improvement in pulmonary compliance can achieve this goal. This can be done by minimizing alveolar edema, recruitment of atelectatic lung with PEEP [e.g. using the stress-index or driving pressure] or instituting the prone position. Importantly, application of PEEP and the prone position can diminish preload by raising Ppl and stiffening the chest wall, respectively [10].. Secondly, finding hemodynamic data within ...
... was originally described in 1946, by Von Euler and Liljestrand - they were studying the effects of hypoxic gas mixtures, and found that PA pressures increased with 10.5% inspired O2 [Von Euler and Liljestrand. Acta Physiol Scand 12: 301, 1946]. Since then, HPV has been well-described in multiple mammalian models, including humans. It is thought to result from a pathway involving NO and/or COOX inhibition [Moudgil R et al. J Appl Physiol 98: 390, 2005]. HPV takes effect over 30 minutes, although peak effect takes up to two hours. Interestingly, HPV sensitization occurs, in which a second incidence of hypoxemia produces a more significant response than the first [Dorrington KL et al. Am J Physiol Heart Circ Physiol 273, H1126, 1997] In addition to PAO2, HPV is dependent on both PaO2 and PvO2, although in the atelectatic lung only PvO2 matters and overall PAO2 is by far most important. Of note, HPV functions best when 30-70% of the lung is hypoxic - if , 30% of ...
