Objective Real‐Time Peripheral Regional Anesthesia Pressure Measurement in Children Using the CompuFlo Device, a Mono‐Center Observational Study
Authors' conclusion
Pressure does not appear to be the main factor prompting the operator to continue or stop the injection.
Study context
- Population
- Children scheduled for peripheral nerve block175 injections analysed
- Participants
- 47 children
- Outcome
- Maximal injection pressure for each injection during PNB (CompuFlo device)
Methodological detailsblinded, single-centre
- Blinded
- Single-centre
Main finding
As reported in the abstract
Maximum injection pressure
Mean maximum injection pressure, mmHg
515
95% CI 478–551
Injections exceeding 750 mmHg threshold
16%
Observational data: associations, not effects.
Further findings
Factors influencing injection pressure
- Operator experience, needle diameter, peripheral nerve block (PNBs) in restricted diffusion space or lack of injection precision, and incorrect ultrasound injection positions
