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.

Guide-wire insertion time
Time frame: interval between skin penetration and removal of the needle or catheter after guide wire insertion, an expected average of 80 seconds
Time to first puncture of central vein
Time frame: interval between skin penetration of the needle or catheter and flashback of blood, an expected average of 25 seconds
Total time of central venous catheter insertion
Time frame: interval between skin penetration of the needle or catheter and installation of the indwelling catheter, an expected average of 3 minutes
Number of central vein puncture trial
Time frame: up to 5 times, an expected average observation time of 25 seconds
Number of guide-wire insertion trial
Time frame: up to 5 times, an expected average observation time of 80 seconds
