From: A feasibility study of a handmade ultrasound-guided phantom for paracentesis
Variables*† | Trainees (n = 50) | Emergency residents (n = 12) | p-Value |
|---|---|---|---|
The sonographic image mimics human tissues | 4 (3–4) | 4 (3–4) | 0.388 |
The puncture texture mimics human skin and the subcutaneous area | 4 (3–4) | 3 (3–4) | 0.353 |
The needle can be visualized during the puncture | 4 (4–5) | 4 (3–5) | 0.601 |
Draining fluid is realistic | 4 (3–5) | 3 (3–4) | 0.072 |
The phantom is durable | 4 (3–5) | 4 (3–5) | 0.523 |
