Conditions

Breast Cancer

Brief summary

The purpose of this study is to learn if paravertebral block (PVB) will reduce chronic pain after surgery. Our hypothesis is that chronic pain from breast surgery as a consequence of central sensitization can be prevented by blocking sensory input to the CNS during surgery and the immediate post-operative period.

Interventions

PROCEDUREParavertebral block

3ml 1% Ropivacaine at each level T1 - T5

Sham injections with Normal Saline
