Midpoint Transverse Process to Pleura Block for Analgesia in Breast Surgeries: A Case Series

Among the various techniques described for analgesia in breast surgeries, thoracic epidural and thoracic paravertebral block is the gold standard but have potential complications of hypotension and pneumothorax. Midpoint transverse process to pleura (MTP) block is one of the newest techniques developed to reduce these complications by injection of local anesthetic between the midpoint of the posterior transverse process and pleura. Originally performed at multiple levels, the literature is scant regarding the placement of a catheter. We report MTP block with catheter placement providing continuous infusion in five patients posted for modified radical mastectomy and found it a safe and effective alternative.
