Comparison of the Combined Serratus Anterior Plane Block Versus Superficial Serratus Anterior Plane Block

Starting soon

Conditions studied: Pain

In brief

Breast cancer is the most common malignancy in women; surgery is a cornerstone of breast cancer treatment, and modified radical mastectomy is one of the standard treatments. Postoperative pain can significantly reduce the quality of life in patients, and acute pain can even trigger chronic pain syndrome. Thoracic paravertebral, thoracic epidural, intercostal nerve, and interscalene brachial plexus blocks have been used for anesthesia and abiration during modified radical mastectomy, but their application is limited due to the complex nature of the procedures and serious complications. In recent years, there has been increasing interest in the newer, less invasive superficial serratus block and combined serratus block. Serratus anterior plane block (SAPB) can be applied in two ways. Deep SPB (DSPB) is applied under the serratus anterior muscle, while superficial SPB (YSPB) is applied above the serratus anterior muscle. In recent years, deep + superficial SPB, or combined SPB (KSPB), has begun to be applied in order to increase the area of effect of local anesthetics and to prevent block failure. This study aims to compare superficial and combined serratus anterior plane blocks.
