Study Description

Adequate acute postoperative pain control is important for patients undergoing breast surgery because the pain may be severe and longlasting. Surgical incision at the breast and axillary areas is associated with significant pain, with high incidence of acute pain progressing to chronic pain in 25% to 60% of patients. Post-mastectomy pain managed with opioids often lead to side effects of nausea and vomiting.

Regional anesthetic techniques are used in the current management of pain associated with breast surgeries .They attenuate surgical stress response , intraoperative consumption of opioid, prevent central sensitization and diminish postoperative pain.

The efficacy of fascial plane blocks like pectoral nerve block (PECS), serratus anterior plane block (SAP), and erector spinae plane block (ESP) has been proven in previous studies. These blocks require deposition of local anesthetic in an inter-fascial plane through which peripheral nerves travel.

The Pectoral nerve block relies upon the deposition the local anesthetic at the inter-fascial planes among the pectoralis major, minor, and serratus anterior muscles: it blocks the pectoral, the intercostobrachial, the intercostals III and VI, and the long thoracic nerves.

Erector Spinae Plane block is another interfacial plane block. It involves deposition of local anesthetic between erector spinae muscle and transverse process of T5 vertebrae and targets both dorsal and ventral rami of thoracic spinal nerves.

Serratus anterior plane block involves the injection of local anesthetic in 1 of the 2 fascial planes, superficial and deep to serratus anterior muscle at the level of the fifth rib in midaxillary line. The SAP block targets the lateral cutaneous branches of the thoracic intercostal nerves. The deep SAP block was found to have similar analgesic efficacy and technically easier and safer to perform as compared to the superficial SAP block.
