Abstract

Breast cancer is the most common type of cancer worldwide. Fortunately, continual advances in diagnosis and treatment are resulting in increased survival rates. Earlier detection and treatment, to include surgical resection, can greatly improve patients outcomes. However, due to the complex innervation of the breast, management of postoperative pain has proven difficult in the past. Approximately, half of all women who undergo breast cancer surgery report postoperative pain syndrome. The paravertebral block has long been the anesthesiologist’s choice for mitigating pain during and after the procedure. Newer techniques such as the pectoral nerve block and erector spinae plane block may prove to have some additional benefits. This literature review compares the risks, benefits and specific uses of these three regional nerve blocks in women undergoing breast cancer surgery. It aims to better inform anesthesiologists when they are choosing which technique is best for their patients.

Plain language summary

Breast cancer is the most common type of cancer worldwide with 2 million new cases each year. Approximately 12% of women are diagnosed with breast cancer at some point in their lives. Part of breast cancer treatment often involves surgery to remove a mass. This can cause pain in both the short and long term. There are multiple different kinds of procedures a person can have done that may decrease the pain, they have from that surgery. These procedures are called nerve blocks. This article examines how well different nerve blocks decrease pain from breast cancer surgery. The nerve blocks we review in this article are called paravertebral blocks, pectoral nerve blocks and erector spinae plane blocks. They all block pain from breast surgery in slightly different ways. The decision of which block is best rests on the person performing the block.
