Paravertebral blocks are becoming increasingly popular, especially as an anesthetic adjunct for breast procedures. New reports suggest additional reasons for adding this block to the anesthetic armamentarium.
Recent studies demonstrate a benefit from preoperative placement of a paravertebral block, not only in reducing acute postoperative pain, but also 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 compared with the general anesthesia-only group of patients.
Paravertebral blocks are a well established option to provide anesthesia and postoperative analgesia during breast surgery. Recent studies suggest additional benefits to this procedure. Not only is acute pain better controlled, but the development of chronic mastectomy pain syndrome and recurrence of cancer may be reduced by preoperative placement of paravertebral block. These studies provide additional reasons why this block should be considered as part of the anesthetic for breast surgery.
椎旁阻滞越来越受欢迎，尤其是作为乳房手术的麻醉辅助手段。新的报告提出了将这种阻滞添加到麻醉药库中的其他理由。
最近的研究表明，术前进行椎旁阻滞有益处，不仅能减轻术后急性疼痛，而且在统计学上能显著降低术后1年发生慢性术后疼痛的患者百分比。另一项研究发现，与仅接受全身麻醉的患者组相比，椎旁阻滞组患者术后36个月时乳腺癌复发率更低。
椎旁阻滞是乳房手术期间提供麻醉和术后镇痛的一种成熟选择。最近的研究表明该手术还有其他益处。不仅能更好地控制急性疼痛，而且术前进行椎旁阻滞可能会减少慢性乳房切除术后疼痛综合征的发生以及癌症复发。这些研究提供了更多理由说明应将这种阻滞视为乳房手术麻醉的一部分。
