| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Infant | Experimental | Radial artery or posterior tibial artery of patients younger than 1 year old are either cannulated with short-axis/out-of-plane or long-axis/in-plane US-guided arterial catheterization technique. |
|
| Preschool child | Experimental | Radial artery or posterior tibial artery of patients older than 1 year old and younger than 5 years old are either cannulated with long-axis/in-plane or short-axis/out-of-plane US-guided arterial catheterization technique. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Long-axis/in-plane US-guided arterial catheterization | Other | 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. |
| Measure | Description | 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 |
| Measure | Description | 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 |
