Summary

ًًًُُُُThe investigators are testing the efficacy of a new novel technique; serratus anterior plane block, for preventing postoperative pain after breast surgery for cancer. This block will be compared with the well-established paravertebral block.

PROCEDURE

Serratus Anterior Muscle Plane block (SAM block)

The US probe is placed in the mid-axillary line at level of the 6th intercostal space. From caudal to cranial, an in-plane approach, the block needle is inserted until the tip is placed between SAM and intercostal muscles and the LA injection will be visualized in real-time. The injection usually consists of 0.4ml/kg of bupivacaine 0.25% plus adrenaline (5ug/ml). Intraoperatively, all subjects will receive a general anesthetic using inhaled anesthetic and oxygen. Intravenous fentanyl will be administered for cardiovascular stability to noxious stimuli.For postoperative analgesia, all subjects will receive oral acetaminophen. Patients will receive a ketorolac IV injection then morphine as a rescue analgesic for breakthrough pain.

PROCEDURE

Paravertebral Block

After skin preparation and sterile draping applied. Target paravertebral space will be located using US guidance. The paravertebral space between the third and fourth thoracic vertebrae will be identified in a parasagittal view approximately 3 cm lateral to midline on the side of surgery. A local anesthetic skin wheal will be raised caudal to the ultrasound transducer. A 17-gauge, Tuohy-tip needle will be inserted through the skin wheal in-plane beneath the ultrasound transducer and directed to the paravertebral space. Normal saline (5 mL) will be injected via the needle to help identify the paravertebral space and observe the pleura being displaced anteriorly. 0.4 ml\\kg of 0.25% Bupivacaine with epinephrine, 5 μg/mL, will be slowly injected with gentle aspiration every 3 mL.
