¿Pueden las diferentes técnicas anestésicas empleadas en cirugía oncológica de mama disminuir el riesgo de recidiva tumoral?

Abstract

Paravertebral blocks are becoming increasingly popular, especially as an anesthetic adjunct for breast procedures. Major breast cancer surgery is associated with a high incidence of postoperative nausea, vomiting and pain. Recent studies have demonstrated a benefit from preoperative placement of a paravertebral block, not only in reducing acute postoperative pain, but also in producing statistically significant reductions in the percentage of patients that develop chronic postsurgical pain 1 year after surgery. Another study found that the breast cancer recurrence rate at 36 months after surgery was lower in the paravertebral group than in a group receiving general anesthesia alone. These studies provide additional reasons for including this block in the anesthetic technique for breast surgery.
