Cooled RF ablations use more energy than traditional RF at >60 s run durations. The energy (in joules, J) used to generate a TRF or CRF ablation was calculated at 50 seconds (s), 80 s, 90 s, 120 s or 150 s. CRF ablation uses more energy at all time points >60 s (80 s, 90 s, 120 s or 150 s) to generate the thermal lesion at the nerve. Bars represent mean±SD. *P<0.05 for n=3–13 per group per timepoint. RF, radiofrequency.
