Which pain block is best after breast surgery? new study compares two options
NCT ID NCT06936852
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compared two types of nerve blocks for pain control after breast surgery: the serratus posterior superior intercostal plane block and the PECS II block. One hundred adults aged 21 to 70 were enrolled. Researchers measured how much morphine patients needed in the first 24 hours and how well they could breathe after surgery. The goal is to find which block provides better pain relief with fewer side effects.
