Diagnostic Values of Lung Ultrasound for Perioperative Atelectasis

April 17, 2015 updated by: The Third Xiangya Hospital of Central South University

Diagnostic Performance of Lung Ultrasound for Perioperative Atelectasis in Adult Patients Undergoing General Anesthesia

Lung ultrasound offers a novel, reliable and radiation-free tool for diagnosing perioperative atelectasis and evaluating its severity in adult patients undergoing general anesthesia in the operating room.

Detailed Description

Atelectases occur in up to 90% of patients undergoing general anesthesia and intubation. The aim of the present observational study was designed to further to evaluate the diagnostic performance of lung ultrasound (LUS) in detection of postoperative atelectasis in adult patients undergoing general anesthesia. Results of LUS as the experimental method will be compared to the results of computed tomography (CT) as the reference technique for the detection of atelectasis. The investigators want to confirm former findings of the appearance of perioperative atelectases and to prove that ultrasound is a valid tool for detection of atelectases.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Correlation between manifestations of atelectasis in lung ultrasound and in thoracic computed tomography.
Time Frame: From 5 minutes before induction of anesthesia to 1 hour after the surgery
Measurements of lung ultrasound are performed before induction of anesthesia and immediately after finishing the surgery. Lung CTs are performed the day before surgery and within 1 hour after surgery. Outcome measure: comparison of atelectases by lung ultrasound (experimental method) versus by computed tomography (standard method)
From 5 minutes before induction of anesthesia to 1 hour after the surgery
