Ketorolac plus Lidocaine vs Lidocaine for pain relief following core needle soft tissue biopsy: A CONSORT-compliant double-blind randomized controlled study.

Patients receiving Lidocaine - Ketorolac combination dosage had significantly lower VAS scores, and these results confirm that local injection of Lidocaine - Ketorolac combination had a superior pain-controlling effect during the first 24 hours after the biopsy procedure in comparison to Lidocaine injection alone, as measured by VAS score scale.
