Summary

The aim of researchers is to compare the effects of three different local anesthetic concentrations and volumes on opioid consumption, postoperative analgesic efficacy, and pain scores during ultrasound-guided SPSIP blocks in patients undergoing modified radical mastectomy. Additionally, we aim to map and identify the dermatomal areas where different concentrations and volumes of SPSIP blocks provide analgesia.

Conditions

  • Modified Radical Mastectomy
  • Post Operative Pain, Acute
  • Facial Plane Blocks

Interventions

PROCEDURE

Serratus Posterior Superior Intercostal Plane (SPSIP) block 40 ml of 0.1875% bupivacaine

A Serratus Posterior Superior Intercostal Plane (SPSIP) block will be performed using 40 ml of 0.1875% bupivacaine (15 ml of the drug + 25 ml of isotonic solution).

PROCEDURE

Serratus Posterior Superior Intercostal Plane (SPSIP) 50 ml of 0.15% bupivacaine

A Serratus Posterior Superior Intercostal Plane (SPSIP) block will be performed using 50 ml of 0.15% bupivacaine (15 ml of the drug + 35 ml of isotonic solution).

PROCEDURE

Serratus Posterior Superior Intercostal Plane (SPSIP) 30 ml of 0.25% bupivacaine

A Serratus Posterior Superior Intercostal Plane (SPSIP) block will be performed using 30 ml of 0.25% bupivacaine (15 ml of the drug + 15 ml of isotonic solution).
