- Objective Real‐Time Peripheral Regional Anesthesia Pressure Measurement in Children Using the CompuFlo Device, a Mono‐Center Observational Study Laurent Hertz Chrystelle Sola Julien Pico Christopher Scott Olivier Choquet Philippe Pirat Anne‐Charlotte Saour Sophie Bringuier Christophe Dadure Pediatric Anesthesia ABSTRACT Background Injection pressure control is one of the several monitoring options when performing a peripheral nerve block (PNB). To date, no data is available in children regarding injection pressure during a PNB. The aim of this blinded prospective observational study was to measure the maximal pressure for each injection during PNBs in a pediatric population. Methods Children scheduled for PNB were eligible for inclusion. During the performance of the block, injection pressures were measured using the CompuFlo device. Factors likely to influence these pressures and the rate of injections exceeding the threshold of 750 mmHg were also recorded. Results In total, 175 pressure injection measurements, recorded in 47 patients, were analyzed. The mean maximum injection pressure was 515 [95% CI: 478–551] mmHg. The pressure exceeded the threshold of 750 mmHg in 16% of injections. Factors influencing injection pressure were operator experience, needle diameter, PNBs in restricted diffusion space or lack of injection precision, and incorrect ultrasound injection positions. Conclusion Pressure does not appear to be the main factor prompting the operator to continue or stop the injection. Other parameters likely to influence injection pressures still seem to be useful and integrated when learning to perform PNBs. 10.1002/pan.70113 http://onlinelibrary.wiley.com/termsAndConditions#vor
