Point of Care Cardiopulmonary Ultrasound Assessment for Acute Lung Injury Patients after Blood Transfusion

Abstract

Point of care ultrasound has a very good application prospect in perioperative period because of its dynamic, real-time and repeatable advantages. At the same time, it has high accuracy and can quickly find the common causes of hypoxemia, such as pulmonary edema, atelectasis and pleural effusion. It is a good visualization tool. Perioperative combined use of cardiopulmonary ultrasound, on the basis of excluding cardiac dysfunction, rapid diagnosis of pulmonary edema. The author conducted a study on two cases of acute lung injury induced by a relatively large amount of blood transfusion. The patients had no prior cardiopulmonary disease, no abnormal findings were found on cardiac ultrasound, hypoxemia, and signs of lung injury were found on bedside pulmonary ultrasound.
