Thoracic Diseases
Conditions
Brief summary
The purpose of the current study is to prospectively evaluate the usefulness of thoracic ultrasonography in demonstrating effective lung isolation during single-lung ventilation (SLV) in the pediatric patient. The primary hypothesis is that ultrasonography will accurately verify lung separation during SLV, as compared to fiberoptic bronchoscope (FOB).
Interventions
Portable ultrasonography done at the bedside.

Outcome results
The Accuracy of Using Ultrasound to Assess Lung Isolation by Visualizing Lung Movement or Lack Thereof of Both the Operative and Non-operative Lung Fields.
Ultrasound will be used to look for lung sliding in the ventilated lung field and lack of lung sliding and presence of lung pulse on the operative/isolated lung field. The effectiveness of this modality will also be compared to the lung auscultation for assessing lung isolation, which along with FOB is the current accepted standards of care.
