Summary
Ultrasound-guided subclavian vein (SCV) cannulation is a safe and effective technique for central venous catheterization in children, especially those who are less than 10 kg. The authors describe a novel ultrasound-guided technique for SCV cannulation in infants and children.
The technique involves placing the ultrasound probe at the supraclavicular level to obtain a longitudinal view of the SCV and then gaining access to the vein via the usual infraclavicular route to cannulate it under ultrasonic control. The authors report a success rate of 84% at the first attempt and 100% after two attempts.
They also describe a case in which they were able to detect an asymptomatic thrombus in the SCV using this technique. The authors conclude that this new technique is a valuable tool for central venous catheterization in children. They believe that it is particularly promising for children who are less than 10 kg, but that it may also be useful for older children.
