Comparative Sensory Mapping of Regional Anesthesia Techniques in Breast Cancer Surgery

Patients will receive a serratus anterior plane block preoperatively under ultrasound guidance. Thirty minutes after the block, the cutaneous sensory area will be assessed using a pinprick test and outlined on the skin using a UV marker. Subsequently, the incision line for the modified radical mastectomy (MRM) will be marked by the operating surgeon. The resulting drawings will be documented and transferred to a digital template for analysis.

Patients will receive a parasternal block preoperatively under ultrasound guidance. Thirty minutes after the block, the cutaneous sensory area will be assessed using a pinprick test and outlined on the skin using a UV marker. Subsequently, the incision line for the modified radical mastectomy (MRM) will be marked by the operating surgeon. The resulting drawings will be documented and transferred to a digital template for analysis.
