Abstract:Background
Precordial Doppler ultrasound technology can be used to confirm correct peripheral intravenous access in children.

However, the location of the precordial Doppler probe has been inconsistent in previous studies. Our study aimed to determine whether the right or left parasternal border is the optimal location for precordial Doppler probe placement.
