Injection pressures measuring for a safe peripheral nerve block.

Injection pressures measuring for a safe peripheral nerve block. Minerva Anestesiol. 2019 May 21;: Authors: Carassiti M, De Filippis A, Palermo P, Valenti C, Costa F, Massaroni C, Schena E Abstract The performance of a precise and safe peripheral nerve blockade (PNB) can currently rely on the aid of the ultrasounds and nerve stimulators. The injection pressure monitoring may be beneficial to perform a safer procedure. This review focuses on the pressures measured during PNB among studies conducted on animal, and human models. From a deep research among the PubMed/MEDLINE database for all reports published in English between January 2004 and November 2018, we selected 15 original papers. We excluded those that were reviews, case-reports, recommendations and correspondences, that didn't match with object of our study. We highlighted the available systems for monitoring injection pressures and classified the reports on the basis of the model used for the respective study (animals, humans, in vitro). Intraneural injections were associated with lower pressures than perineural ones. High injection pressures registered at the needle tip were associated with an increased risk of nerve damage. Actually, a precise cut-off pressure values has not emerged from the literature for a safe PNBs yet, but it is possible to affirm, based on the literature currently available, the threshold of 15 psi seems to be an acceptable value under which it is pos...
