Brief Summary:
Postoperative hypoxemia was persistent and common after surgery.Rapid diagnosis and subsequent therapeutic measures must be adopted by anesthesiologists.Lung ultrasound has been confirmed to be more sensitive and accurate for diagnosis of pulmonary ailment than chest radiography.The primary objective of the present study was to evaluate lung complications by bedside lung ultrasonography on patients suffered from hypoxemia after general anesthesia in the postoperative period.

Primary Outcome Measures :
  1. Pulmonary Complications of Lung Ultrasound [ Time Frame: 20 minutes after tracheal extubation ]
    Pulmonary disease including atelectasis, pneumonia, pneumothorax and pleural effusion would be discovered by lung ultrasound

Secondary Outcome Measures :
  1. Comparison of Lung Ultrasound and Computed Tomography(CT) [ Time Frame: Within 1 hour after examnation of Lung Ultrasound ]
    Lung ultrasound offers high sensitivity and specificity when compared with CT

Other Outcome Measures:
  1. Correlative Factors of Lung Ultrasound Score [ Time Frame: Through study completion, up to 8 months ]
    Higher score value represent more ventilation loss
