Lung Deflation in Pediatric Subclavian Vein Catheterization (SCVLD)
|Pediatric Subclavian Vein Catheterization||Procedure: lung deflation Procedure: lung inflation|
|Study Design:||Intervention Model: Single Group Assignment
Masking: Single (Investigator)
Primary Purpose: Supportive Care
|Official Title:||The Effect of Lung Deflation on the Position of the Pleura in Mechanically Ventilated Infants During Subclavian Vein Cannulation: an Ultrasound Study|
- The distance between the pleura and the line of the imaginary needle pathway (DPI) [ Time Frame: Within 5 minutes ]
The ultra-sonography probe was adjusted to obtain an image containing the long-axis cross section of SCV, the pleura, the clavicle, and the first rib. Images were recorded by the same physician during whole respiratory cycle with the probe held in the identical position.
Imaginary lines for supraclavicular and infraclavicular approach were drawn, and distances from the pleura were measured.
If the pleura touched the INP, the distance was recorded as positive value. If the pleura did not touch the INP, the distance was recorded as negative value.
- The incidence of pleural movement over the imaginary needle pathway [ Time Frame: Within 5 minutes ]If the pleura touched the imaginary needle pathway, the incidence was checked.
