Arterial Catheterization, Child, Ultrasound
Conditions
Brief summary
Investigators designed a prospective randomized controlled study to compare the long-axis/in-plane and short-axis/out-of-plane methods during the ultrasound-guided arterial catheterization in pediatric patients younger than 5 years old.
Interventions
Cannulate the radial artery or posterior tibial artery of an infant of a preschool child putting the 24 gauge needle parallel to the ultrasound transducer.
Cannulate the radial artery or posterior tibial artery of an infant or a preschool child putting the 24 gauge needle perpendicular to the ultrasound transducer.

Inclusion criteria
* Surgery under general anesthesia * Requires invasive arterial blood pressure monitoring
Exclusion criteria
* Infection/hematoma/skin disease/arteriovenous fistula/recent catheterization scar in radial artery or posterior tibial artery * Peripheral vascular disease * Congenital aortic disease
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Arterial catheterization time | Interval between contact of the ultrasound transducer with the skin and confirmation of an arterial waveform on the monitor, an expected average of 200 seconds |
Secondary
| Measure | Time frame |
|---|---|
| Ultrasound imaging time | Interval between contact of the ultrasound transducer with the skin and penetration of the needle through the skin, an expected average of 30 seconds |
| Time to first puncture of the artery | Interval between skin penetration of the needle and flashback of blood, an expected average of 100 seconds |
| Number of puncture attempts | Up to 5 times, an expected average observation time of 600 seconds |
