Lung Ultrasound and Alveolar Recruitment in Mechanically Ventilated Infants

Preventive Effect of Lung Ultrasound and Alveolar Recruitment on Atelectasis in Mechanically Ventilated Infants

Investigators hypothesized that lung ultrasound-assisted recruitment maneuver would be beneficial in mechanically ventilated infants compared to those who did not receive lung ultrasound and alveolar recruitment maneuver.

Inclusion Criteria:

• Minor surgery less than 2 hours under general anesthesia
• Mechanically ventilated after endotracheal intubation

Exclusion Criteria:

• History of surgery on the lungs
• Laparoscopic surgery
• Abnormal preoperative chest radiograph findings including atelectasis, pneumothorax, pleural effusion, and pneumonia
• Considered inappropriate by the investigator
