(2008) performed another study that also confirmed concurrent and construct validity of the FLACC
pain assessment tool, not only in the post-operative setting, but also during the procedural setting.
* Each newborn to be circumcised was assessed for pain using the FLACC
pain scale before, during, and after the procedure.
scale was developed to reduce these potential barriers by providing a simple framework for assessment, while facilitating a reliable and objective means of quantifying pain behaviors in children.
Comparison of the FLACC
Scale with the UWCH Scale would also be useful.
to test the validity of the FLACC
tool by measuring changes in FLACC
scores in response to administration of analgesics, and to compare the FLACC
to other pain assessment tools.
The sample size was estimated as a minimum of 19 subjects for each study group to find a 30% difference in FLACC
scores between the groups based on a previous study (9), at a significance level of 5% and a power of 95%.
For all participants, pain levels were assessed using both a behavioral scale (FLACC
scale) and a self-report scale (NRS).
Patient's postoperative FLACC
pain scores at 1, 6, 12, and 24 h; postoperative analgesic doses; and complications such as nausea, vomiting, hypotension, infection at the site of the block, and hematoma were evaluated from patients' records.
Post-operative pain was assessed and evaluated by the FLACC
The variation of heart rate and skin conductivity between the moments prior to and during anesthesia was measured, which also evaluated patient behavior and the degree of pain experienced at the point of administering anesthesia using the FLACC
conformity or pain scale.

By the end of the operation, FLACC
(Face, Leg, Activity, Cry, Consolability) pain score was assessed as the primary outcome of the study.
