Atelectasis is a complete or partial collapse of a lung or lobe of a lung develops when the tiny air sacs (alveoli) within the lung become deflated. It's a breathing complication after surgery. The amount of lung tissue involved in atelectasis is variable, depending on the cause. Atelectasis can make breathing difficult and lower oxygen particularly if lung disease is already present. Treatment depends on the cause and severity of the collapse.
Atelectasis is likely to occur when you're already in a hospital. However, seek medical attention right away if you have trouble breathing. Other conditions besides atelectasis can cause breathing difficulties and require an accurate diagnosis and prompt treatment. If your breathing becomes increasingly difficult, seek emergency care. Obstructive atelectasis may be caused by Mucus plug, Foreign body, Narrowing of major airways from disease, Tumor in a major airway, Blood clot. Possible causes of nonobstructive atelectasis include Injury, Pleural effusion, Pneumonia, Pneumothorax, Tumor.
There may be no obvious signs or symptoms of atelectasis. None of the 16 patients who had thoracoscopy developed atelectasis, but this also was not a significant finding. We conclude that severe postoperative atelectasis occurs as lobar atelectasis in approximately 5 per cent of patients who undergo pulmonary resection and significantly adds to the intensive care unit and hospital length of stay. The etiology of lobar atelectasis appears to be multifactorial and warrants further study to define mechanisms of occurrence and their prevention.
