Summary

Ultrasound-guided Serratus anterior plane (SAP) block is an interventional technique that recently gained popularity in the context of postoperative analgesia after breast surgery. Some limitations may be encountered during the use of ultrasound, such as obesity, tumor invasion of the surrounding muscles, which may lead to poor ultrasound image quality. The investigators hypothesized that an open approach to serratus anterior block by infiltration of local anesthetic between serratus anterior muscle and ribs after tumor excision during surgery would be non-inferior to ultrasound-guided approach where the primary endpoint of this prospective randomized blind controlled study will be the total dose of morphine consumed in the 1st postoperative 24 h. The patients will be randomly allocated to an open approach group and ultrasound approach group to serratus anterior block using computer-generated random numbers and sealed opaque envelops. For any statistical tests used results will be considered as statistically significant if P-value ≤0.05.

Conditions

  • Analgesia

Interventions

PROCEDURE

ultrasound approach of serratus anterior block

After induction of general anesthesia, the ultrasound probe will be placed longitudinally oblique just below the mid-clavicle. After identifying the second rib, the probe will be moved caudally and laterally (obliquely), towards the mid-axillary line to identify the 3rd, 4th and 5th ribs.. The fascial plane between the serratus anterior muscle and latissimus dorsi muscle will be identified over the 4th rib in the mid-axillary region. The block will be performed with a needle (22-G, 50-mm) introduced in-plane to enter deep to the serratus anterior muscle, and 30 ml 0.25 bupivacaine will be injected.

PROCEDURE

open approach of serratus anterior block

After resection of the breast and identification of the serratus anterior muscle, the surgeon will be asked to palpate the ribs below the clavicle and localize the fourth rib. A 22-G, 50-mm needle will be introduced deep to the serratus anterior muscle contacting the rib, and 30 ml 0.25 bupivacaine will be injected.
