Intraosseous catheter confirmation with central venous color flow and doppler waveform, a randomized single-blinded trial
Authors' conclusion
Awareness of procedural POCUS specific to the use of color flow and doppler waveform to confirm IO placement may provide additional assurance that an IO catheter has been successfully placed, remains in position, and is functioning safely.
Study context
- Population
- Fresh, never frozen, unembalmed, consented cadavers
- Comparison
- Standard vs Comparison
- Primary endpoint
- Proximal central venous color flow and doppler waveform on POCUS during IO infusion
Methodological detailssingle-blinded, cadaver model
- Single-blinded
- Cadaver model
Primary result
As reported in the abstract
Proximal central venous color flow and doppler waveform identified by blinded POCUS operator
Comparison
7%
- Unblinded operators identified proximal venous color flow and doppler waveform in all intentionally placed intraosseous (IOs)
- 100%
Further findings
Volume required to produce color and doppler flow, by site
- Correctly placed tibial IOs required more volume on average than humeral IOs
