U/S Guided vs. Traditional Palpation for Radial Artery Cannulation
U/S Guided vs. Traditional Palpation for Radial Artery Cannulation
The purpose of this study is to compare the efficacy of ultrasound- guided with the
 traditional palpation radial artery cannulation in critically ill children.
Arterial catheterization is often performed in critically ill patients for continuous
 hemodynamic monitoring and blood sampling. However, insertion of radial artery catheter with
 traditional palpation may be technically challenging, particularly in pediatric patients.
 There are few published studies on the use of ultrasound guidance for radial-artery catheter
 placement and mostly they were elective surgery children which received inhalation or deep
 sedative medication. Recently no setting published in pediatric intensive care unit.
Inclusion Criteria:

 -  Pediatric patients who required radial artery cannulation for hemodynamic monitoring
 or frequent blood samples in intensive care unit

 Exclusion Criteria:

 -  Wound at area of cannulation

 -  Can not palpate or weak radial artery pulse
