The purpose of this study is to compare the differences in central venous catheter insertion time, success rate, and complication between thin-wall needle technique and catheter-over-the-needle technique for central venous catheterization in children.
Catheterization was performed using ultrasound with an "out-of-plane" approach by inserting the introducer needle (thin-wall needle technique) or Angiocath Plus™ catheter (catheter-over-the-needle technique) in 45 - 60° to the patient's skin while viewing the vein in a cross section.
