Nerve block efficacy in breast augmentation: A systematic review and meta-analysis

Area of Science:

• Anesthesiology
• Plastic Surgery
• Evidence-Based Medicine

Background:

• Breast augmentation commonly utilizes general anesthesia with opioid-based pain management.
• Regional anesthesia, through various nerve block techniques, presents an alternative for managing postoperative pain and reducing analgesic needs.

Approach:

• A systematic review and meta-analysis were conducted following PRISMA guidelines.
• Included were randomized or quasi-randomized studies comparing regional anesthesia with nerve blocks to general anesthesia for breast augmentation.
• Primary outcomes assessed were postoperative pain scores and analgesic requirements.

Key Points:

• Nerve blocks demonstrated statistically significant reductions in postoperative pain scores at all measured time points (0, 1, 2, 4-6, and 24 hours).
• A significant decrease in postoperative opioid requirements was observed, with a reduction of -150 mcg fentanyl.
• Study heterogeneity was noted, but findings consistently support the efficacy of regional anesthesia.

Conclusions:

• Regional anesthesia with nerve blocks is an effective strategy for reducing postoperative pain in breast augmentation.
• This method also leads to a significant decrease in the need for postoperative opioids.
• Regional anesthesia offers a valuable alternative to general anesthesia for breast augmentation surgery.
