Local Anesthetic Infiltration for Pain Control in Aesthetic Breast Reduction Surgery: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

[BACKGROUND] Aesthetic breast surgeries, including breast reduction, are commonly performed surgical procedures associated with postoperative pain. Pain control is essential to patient comfort, satisfaction, and early recovery. This systematic review is the first to conduct both qualitative and quantitative analysis to evaluate the efficacy and safety of local anesthetic infiltration in reducing pain after breast reduction surgeries.

[METHODS] This systematic review is registered in PROSPERO, assessed for bias using the RoB2 tool, and follows the PRISMA guidelines. A full electronic search was performed in different databases for all clinical papers on adult female patients undergoing cosmetic breast reduction surgery who were given local anesthetic infiltration for postoperative pain relief.

[RESULTS] A systematic review of five randomized clinical trials with a total of 191 patients found that local anesthetic infiltration significantly reduces postoperative pain in breast reduction surgery, reduces opioid consumption, and improves patient outcomes. A meta-analysis of two trials reported the mean VAS score for postoperative pain in the local anesthetic and placebo groups.

[CONCLUSION] A systematic review and a meta-analysis show a significant reduction in postoperative pain following local anesthetic infiltration, but further research is needed to understand its effectiveness and potential adverse effects.
