Analgesic Efficacy of Ultrasound Guided Serratus Anterior Plane Block and Pectoral Nerve Block II

Not Applicable

Recruiting

• Conditions: Anesthesia; Radical Mastectomy

• Registration Number: NCT06188156
• Lead Sponsor: Azhar University

Brief Summary

Modified Radical Mastectomy accounts for 31% of all breast surgeries and considered the fundamental surgical management for breast cancer. Nearly 40-60% of patients experience severe acute postoperative pain. This pain might persist for 6-12 months and result in post-mastectomy pain syndrome and complex regional pain syndrome (causalgia)

Detailed Description

There are some local or regional nerve blocks in breast surgeries performed as core components of multimodal analgesia and enhanced recovery after surgery (ERAS), including thoracic epidural (TEB), interscalene brachial plexus, paravertebral, ultrasound-guided pectoral nerve block ( PECS II ), ultrasound-guided serratus anterior plane block (SAPB) and erector spinae plane block .

Thoracic epidural (TEB) is the gold standard technique following breast surgery, but there is still a problem with the adequacy of thoracic and axillary blockage during lymph node dissection .

Modified PECS's block" or PECS block type II aimed to block the axilla that is vital for axillary clearances and the intercostal nerves, necessary for wide excisions which can provide analgesia after breast surgery.

In the ultrasound-guided serratus anterior plane block (SAPB), the local anesthetic (LA) is injected in the compartment between the serratus anterior and latissimus dorsi muscles. SAPB anesthetizes the intercostobrachial nerve, lateral cutaneous branches of the intercostal nerves (T3-T9), long thoracic nerve, and thoracodorsal nerve thus providing analgesia for breast and lateral thoracic wall surgeries
