Summary

Modified radical mastectomy (MRM) is one of the most common surgeries performed, and one that may be associated with significant acute postoperative pain in breast surgery. Acute postoperative pain is an independent risk factor in the development of chronic post-mastectomy pain .

Various regional anesthetic procedures have been tried to provide better acute pain control and, consequently, less chronic pain. They can reduce perioperative opiates requirement and thereby decreasing their possible side effects. These regional procedures include local wound infiltration, lumbar intrathecal fentanyl injection, thoracic epidural, thoracic paravertebral block (PVB), and ultrasound (US)-guided interfascial plane blocks. Currently, Ultrasound (US)-guided interfascial plane blocks have been recommended as safe, easy, and reliable alternatives to the use of thoracic epidural and paravertebral blocks in providing analgesia for patients about to undergo breast surgery.

Serratus anterior plane block (SAPB) is one of the Ultrasound (US)-guided interfascial plane blocks, it blocks the intercostal nerves II-VI by injection above or below the serratus muscle in the mid-axillary line and spares the pectoral nerves.

We assumed that SAPB could safely provide a better analgesic profile with an opioid-sparing effect than Intrathecal fentanyl. We will perform this study to evaluate this assumption.

Conditions

  • Patients Undergoing Modified Radical Mastectomy

Interventions

PROCEDURE

Serratus Anterior Plane Block

SAPB will be done preoperative before induction of anesthesia under songraphic guidance and aseptic conditions with the patient in the lateral position, with the side of the surgical side up and the upper limb hanging over the patient's head. The ribs will be then counted, and when the 5th rib is identified, the high-frequency probe will be put over it, in the mid-axillary line in a sagittal plane. The ribs, pleura, overlying serratus muscle and latissimus dorsi muscle will be identified, and the needle will be advanced cephalic in-plane until the tip reaches the plane between the serratus anterior and latissimus dorsi. Afterward, 2 mL dextrose 5% will be injected; then, 30 mL of bupivacaine 0.25% will be injected in the plane between the serratus anterior and latissimus dorsi.

PROCEDURE

Lumbar Intrathecal Fentanyl Injection

Patients will receive 25 microgram intracthecal fentanyl immediately preoperative.
