* Surgeon agrees with the block plan by APS.

Exclusion Criteria:

* Patient declines a peripheral nerve block.
* Patient declines to be a study participant.
* APS team believes a peripheral nerve block is not clinically indicated.
* Surgeon does not want a peripheral nerve block.

About the study

Perform a comparison of effective pain relief duration between liposomal bupivacaine and dexmedetomidine when added to bupivacaine in a block for mastectomy for cancer surgery. The erector spinae plane block is a well-established block that is utilized for post operative pain control for procedures performed on the soft tissue of the chest and chest wall as well as intrathoracic procedures. The goal is comparison of the effective duration of both study groups to determine if there is a significant difference in time and amount of post operative opioids required which admitted to hospital.
