NCT02355405 | Completed DMC

• 1 other identifier: XY3-LUS-8711
• Study Type: observational
• Target: 46
• Locations: 1 country
• Sites: 2

Brief Summary

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.

Conditions

Postoperative Pulmonary Atelectasis

Keywords

lung ultrasound; atelectasis; thoracic computed Tomography

Outcome Measures

Primary Outcomes (1)

• Correlation between manifestations of atelectasis in lung ultrasound and in thoracic computed tomography.

  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

Interventions

lung ultrasound DEVICE

lung ultrasound investigations were performed right before and after the surgical procedure.

thoracic computed tomography RADIATION

thoracic CT were performed within one hour after the LUS investigation
