Combined Fascial Plane Blocks Fail to Superiorize Paravertebral Block in Mastectomy: Results from a 1,507-Patient Cluster-Randomized Trial

Combined Fascial Plane Blocks Fail to Superiorize Paravertebral Block in Mastectomy: Results from a 1,507-Patient Cluster-Randomized Trial

A large-scale cluster-randomized trial involving 1,507 patients demonstrated that adding PECS I blocks to paravertebral or serratus anterior plane blocks does not reduce postoperative opioid use or improve recovery compared to paravertebral block alone in mastectomy with reconstruction.
