Lung ultrasound in the intensive care unit

摘要: Although air is a natural obstacle to ultrasound, observation has shown that the majority of acute lung disorders can be investigated using ultrasound. Lung probably under-employed technique, relies on simple but basic principles. A small, affordable device necessary and sufficient The pattern pneumothorax absent sliding with horizontal lines arising from pleural line, sensitivity 100%. Pneumothorax confidently ruled out if peak observed (negative predictive value 100%), or long, well-defined comet-tail artifacts line are visible 100%). Can diagnosed specificity 100% probe record fleeting inspiratory appearance signs. Interstitial syndrome also proved accessible Comet-tail artifacts, multiple diffuse surface, correlated interstitial 93%. distance between two comet-tails allows one distinguish thickened interlobular septa ground-glass areas. Alveolar consolidation gives tissular instead normal aerated image, inconstant hyperechoic punctiform areas without respiratory variation size. Ultrasound 91%, Diagnosis effusion familiar field, whose semiology nonetheless requires accurate definition. dependent collection limited by visceral parietal pleura, interpleural thickness moving depth superficy during cycle, yields 94%. Sensitivity ultrasound 86% for all effusions, 97% effusions larger than 10 mm posterior in supine patients. Ultrasound-aided thoracentesis safe procedure, even case radio-occult ventilated patients, zero complication rate success 97%. Atelectasis, abscess, diaphragmatic dyskinesia other too benefit In these disorders, proves as, not more, efficient bedside radiography. major advantage quick diagnosis. Other advantages simplification diagnostic process, reduced need radiography CT, i.e. lowering irradiation cost reduction, investigation dyspneic among others. All should lead more widespread use provided problem, training, solved.
