The Effect of Thoracal Paravertebral Block on Seroma Reduction in Breast Surgery

The Effect of Thoracal Paravertebral Block on Seroma Reduction in Breast Surgery, a Randomised Controlled Trial

Thoracal paravertebral block (TPVB) is a commonly prefferred regional anesthesia technique to provide postoperative analgesia. In addition, the successful use of TPVB is reported for some seroma related pain cases. Postoperative analgesia in breast surgery is a difficult and overworked issue due to etensive surgery and complex innervation of the breast and in addition to this complex mechanisms, seroma accumulation has a negative effect for patients postoperatively. With this study, the investigators aimed to study the effect of TPVB on seroma reduction for breast cancer surgery.
