Does more fluid mean less pain? new study tests C-Section injection volumes
NCT ID NCT07616180
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two different volumes of the same painkiller (bupivacaine) given as a TAP block after cesarean section. The goal is to see if a larger volume provides better pain relief without increasing side effects. Fifty full-term mothers having planned C-sections will take part. The main measure is how much additional morphine they need after surgery.
