Modified Pectoral Nerves Block Versus Serratus Plane Block in Major Breast Cancer Surgery

A Comparative Study for Evaluation of the Analgesic Profile of Ultrasound-Guided Modified Pectoral Nerves Block Versus Serratus Plane Block in Major Breast Cancer Surgery

The purpose of this study is to compare the analgesic profile of modified pectoral nerves block and serratus plane block in patients undergoing mastectomy.

This study includes three groups. The first group will receive ultrasound-guided modified pectoral nerves block prior to induction of general anesthesia. The second one will receive ultrasound-guided serratus plane block prior to induction of general anesthesia. The third one will not receive any block preoperatively.

Inclusion Criteria:

• American Society of Anesthesiologists( ASA) I or II and scheduled for major breast cancer surgery( modified radical mastectomy or conservative mastectomy with axillary evacuation).

Exclusion Criteria:

• Local infection at the site of the block, coagulations abnormalities, allergy to local anesthetics or morphine, body mass index> 35, patient refusal, severe respiratory or cardiac disorders, pre-existing neurological deficits, hepatic or renal insufficiency, chronic pain syndrome, chronic analgesic use and psychiatric disorders.
