Khoang màng phổi, một mục tiêu cơ bản trong các bệnh nhân bị bệnh nặng, có thể truy cập vào siêu âm. Có thể chính xác chẩn đoán tràn dịch màng phổi, để xác định bản chất của nó, và phân tích nó một cách an toàn thông qua trực tiếp đâm thủng, thậm chí ở một bệnh nhân thông gió. | References 95 25.

Ann Intern Med 98 891-899 CHAPTER 15 Pleural Effusion and Introduction to the Lung Ultrasound Technique The pleural cavity a basic target in the critically ill patient is highly accessible to ultrasound. It is possible to accurately diagnose pleural effusion to specify its nature and to safely analyze it through direct puncture even in a ventilated patient. Traditionally thoracic ultrasound is limited to the exploration of pleural effusion with variable penetration. We will see in the following chapters that this vision can be broadened. If the indication of pleural effusion alone is considered and even though it was described long ago 1 this application is not exploited to its fullest in all institutions. A lack of solid data may explain this paradoxical situation. We will use this chapter to introduce the basic notions of lung ultrasound. Basic Technique of Pleuropulmonary Ultrasonography Lung ultrasound is a dynamic approach. It requires precise definition of the patient s situation with respect to the earth-sky axis. Fluids want to descend gases to rise. We can thus separate lung disorders into dependent disorders which include pleural fluid effusion and a majority of alveolar consolidations and nondependent disorders which include pneumothorax and generally interstitial syndrome. The critically ill patient can be examined supine or sometimes laterally rarely in an armchair almost never in the prone position. .
