Primary outcome of our study is to compare the effectiveness of two regional anesthesia techniques, ESP block and TPV block, in the post-operative pain-control after radical mastectomy.~We will also evaluate both intra and post-operative opioid consumption, the incidence of PONV, the length of hospital stay, patient satisfaction with the anesthesiology technique and the incidence of chronic pain 6 months after surgery.
The aim of the study is to compare the effectiveness of the Erector spinae plane (ESP) block versus thoracic paravertebral (TPV) block in the post-operative pain control after radical mastectomy.
