Subgroup Analysis From A Multicenter, Randomized, Double-Blind, Controlled Trial Of Liposomal Bupivacaine Transversus Abdominis Plane Block For Cesarean Births

The use of transversus abdominis plane (TAP) block with long-acting liposomal bupivacaine (LB) after cesarean was shown to decrease opioid consumption in the primary analysis of a randomized, double-blind study (NCT03176459). Here, we present an analysis across subgroups to assess whether opioid-reducing benefits would differ in patients on the basis of baseline characteristics.
