In 30 seconds
This randomized controlled trial evaluated the impact of peribulbar block (PB) volume on intraocular pressure (IOP) changes in 50 patients undergoing intraocular surgery. The study found no significant difference in IOP changes between 4 mL and 7 mL block volumes; however, the 7 mL group reported higher surgeon satisfaction scores, indicating its potential as a more effective anesthesia method.
Key findings
- No significant difference in IOP change after 4 mL vs 7 mL block volumes.
- Both groups showed significant IOP decrease after ocular massage.
- The 7 mL group achieved a significantly higher surgeon satisfaction score.
Why it matters
Understanding the optimal volume for peribulbar blocks can enhance surgical outcomes and patient safety in ophthalmic procedures. Improved surgeon satisfaction may correlate with better overall patient care.
