What is it about?
Peripheral intravenous (PIV) access infiltration can cause serious complications. Thus, early detection is desired. However, there is no effective and objective method to detect PIV infiltration. Precordial Doppler ultrasound has been historically used during general anesthesia to detect air embolism during neurosurgery. We found a change in the Doppler sound and measured blood flow velocity immediately after injecting normal saline can be used to confirm correct PIV access in children.

Why is it important?
Currently, reliable, objective methods to confirm correct PIV access are not established in children. Moreover, direct observation is limited for anesthesiologists during surgery because of draping the patient. Precordial Doppler ultrasound technology can be a reliable method to confirm PIV access even under limited access to the patient during surgery. This method can be applied outside operating rooms.
