Testing of Pre-Operative Peripheral Nerve Blocks in Randomised Controlled Trials: A Scoping Review.

ABSTRACT:

Background

Peripheral nerve blocks are widely used for anaesthesia in upper and lower limb surgery, but the methods used to assess their success vary substantially. This scoping review examined contemporary research practises and the extent to which trials report on peripheral nerve block evaluation.

Methods

A search was conducted on PubMed for randomised controlled trials published between 2014 and 2025 in anaesthesia journals, involving pre-operative peripheral nerve blocks in adults undergoing limb surgery. Two independent authors screened and extracted data for each trial. Outcomes included the proportion of trials that reported block testing, described test methods, defined successful blocks, and reported success rates.

Results

Of 284 trials included, 215 (76%, 9
