Brief Summary
The high incidence of breast cancer is increasing the need for oncologic breast surgery. The optimal acute postoperative pain management after breast surgery is not yet clear. The erector spinae plane block (ESPB) is a newer and may be potentially safer alternative other regional analgesia techniques. We will investigate the effectiveness of ESP for managing acute pain after breast cancer surgery. Patients will randomise to receive either ESP block (Group1)or no ESP block (Group II). The primary outcome is postoperative pain scores used Visual Analog Scale (VAS), and the secondary outcomes include intraoperative opioid consumption postoperative total opioid consumption and patient satisfaction.

Outcome Measures
Primary Outcomes (1)
Remifentanil Consumption
The primary aim of our study was to compare perioperative remifentanil consumption between Group I patients who received a preoperative ESP block and Group II patients who underwent surgery without the block.
From beginning of anesthesia to finished the surgery
Secondary Outcomes (3)
postoperative morphine consumption
from the end of the surgery to 24 hours of postoperative
The VAS scores
from the end of the surgery to 24 hours of postoperative
patient satisfaction
at the 24th postoperative hour
Study Arms (2)
Group I
ACTIVE COMPARATORThe group with ESP block was defined as Group 1. The ESP block was performed unilaterally in the direction of the surgery.
Group II
NO INTERVENTIONThe group without ESP block was defined as Group II.
Interventions
The ESP block was performed unilaterally in the direction of the surgery by the same anesthetist. Blocks were performed using an Esaote ultrasound device (Esaote My Lab 6 US machine, Florence, Italy), a multifrequency convex probe (1-8 MHz), and a 22-gauge, 50 mm facet needle (B. Braun Sonoplex, Melsungen, Germany). The block needle was placed at the level of the T4 spinal process using the in-plane approach, approximately 3 cm lateral to the T4 spinous process in the parasagittal plane. After visualizing the transverse process with the in-plane approach, the 50 mm facet needle (B. Braun Sonoplex, Melsungen, Germany) was inserted through the skin, and a test dose of 1 ml of 0.9% NaCl was injected between the fascia of the trapezius, rhomboid, and erector spinae muscles and the transverse vertebral process to confirm the location. A total of 20 ml of 0.5% bupivacaine was used as a local anesthetic.
