Randomized Controlled Trial Comparative Study Clinical Trial
A randomized, double-blind trial of pre-emptive local anesthesia in day-case knee arthroscopy.
The study goal was to assess the efficacy of pre-emptive analgesia in a clinical setting. ⋯ Prophylactic local anesthesia confers no statistically significant reduction in pain scores or perioperative general anesthetic requirements as compared with postoperative administration. The pre-emptive effect in clinical practice may be less dramatic than that observed in more controlled animal models. Further studies are required to investigate the magnitude of the pre-emptive effect in clinical practice.
