Use of both MV and tracheostomy increases risk for lower respiratory tract infection, secretion retention, atelectasis, and respiratory failure.
Respiratory complications remain the leading cause of mortality and morbidity following acute spinal cord injury (SCI).[2,11,73,54] Mortality rates from pulmonary complications during the first year following SCI range from 40-80%.[1,37,11,16] Atelectasis, pneumonia and respiratory failure develop following SCI due to physiologic changes in the thoracic and abdominal musculature and diaphragm which ensue due to disrupted innervation.
The news is bad for SCI survivors who smoke, much worse than for the general population: a greater likelihood of atelectasis (collapsed lung), an increased incidence of skin sores, and a decreased ability to heal following skin surgeries.
These included operations of the cardiac, internal, and nervous systems; pneumonia; atelectasis; respiratory infections; kidney problems; fainting; and headaches.
atelectasis, a symptom in respiratory disorders is not defined anyplace in the book.
The reduced lung expansion is a consequence of atelectasis, which occurs due to a lack of surfactant.
Various radiologic findings may be present in patients with EBMs such as mediastinal lymphadenopathy, hilar masses, atelectasis, multiple pulmonary nodules, as well as normal chest radiography.
The patients were monitored post-operatively for pulmonary (respiratory failure requiring ventilatory support, atelectasis, pneumonia, pulmonary embolism, pleural effusion/hemothorax, etc.), cardiac (arrhythmias, myocardial infarction, and congestive cardiac failure), and surgical complications (wound infections, anastomotic leak, and fistula formation).
Twelve children (10.2%) developed atelectasis and five (3.2%) developed pneumothorax during the course of ventilation.
Here we describe a case of primary ALCL of the lung in a patient who made a complete recovery after presenting with complete left upper lobe atelectasis.
Postoperative pulmonary complications (PPC) such as hypercapnia, atelectasis, and pneumonia which increase mortality are particularly attributable to adverse prognosis in patients with thorax surgery specially with lobectomy [1].
The patient's relatively long, untreated clinical course, atelectasis, and hydrostatic pulmonary edema might have developed before his admission.
