Official title
Effect of Local Warming for Arterial Catheterization in Pediatric Cardiac Surgery: A Prospective Randomized Controlled Study
Overview
The increase in internal diameter (ID) and cross-sectional area (CSA) may facilitate better arterial catheterization. Since an increase in body temperature can cause peripheral vasodilation, we aimed to determine if local warming of the radial artery (RA) catheterization site could improve the success rate of catheterization in pediatric patients.
Detailed description
This randomized, controlled study enrolls 126 pediatric patients aged ≤ 2 years who were scheduled for heart surgery. They are randomized into non-warming (C) and warming (W) groups. After induction, the baseline artery ultrasonography images are collected. In the warming group (W), local warming is applied on the catheterization site. Before catheterization, the artery ultrasonography images are collected. The primary outcome is the first-attempt success rate. The secondary outcomes included the ID and CSA of the artery and overall complications.
Interventions
- Procedure local warming
local warming on the site for arterial catheterization using forced air warmer
Primary outcome measures
- first-attempt success rate of arterial catheterization [Time frame: baseline, imediate after arterial catheterization]
Secondary outcome measures (1)
- internal diameter (ID) and cross-sectional area (CSA) [Time frame: baseline, imediate after arterial catheterization in the non-warming group, or warming group]
Eligibility criteria
