The goal of this study is to compare the analgesic effects of ESPB and PECS II blocks in patients undergoing BCS. The main question it aims to answer is:
Our study included patients who were female, who were going to undergo elective breast-conserving surgery between March 2022 and August 2022.
The patients to be included in our study were divided into two groups as ESPB group or PECS II group by an anesthesia assistant independent of the study using a computer-based randomization program one day before the operation. All patients were informed about the block in the preoperative period, the use of the patient-controlled analgesia device to be used after the operation, and Visual Analog Scale (VAS) assessment. (Patients were asked to indicate their pain on a scale where 0 represented "no pain" and 10 represented "unbearable pain.)
On the day of the operation, group envelopes were placed in the patient files to indicate the groups in sealed envelopes. The appropriate anesthesia method was applied to the patient according to the group written on the patient's envelope by the relevant anesthesiologist on duty in the study. Our study was conducted as a randomized controlled and prospective study.
VAS scores at 0, 15, 30, 60 minutes postoperatively recorded for the primer output of the study. For the secondary outputs the total amount of analgesic used was recorded from the records of the PCA device. All patients' demographic data, intraoperative hemodynamic data, anesthesia duration, surgical duration and hospital stay, VAS at 4, 6, 12, 24 hours in the service follow-up, rescue analgesic requirements and numbers, nausea-vomiting and developing complications were evaluated and recorded. The evaluations were made by the anesthesiologist who was blind to the groups.

| Erector Spinae Plane Block | Procedure | ESPB was applied to the patients in a sitting position. A high-frequency linear probe was used. Under sterile conditions, the USG probe was placed longitudinally approximately 2 cm lateral to the T4 spinous process. Skin, subcutaneous fat tissue, m. trapezius, rhomboid muscles, erector group muscles, transverse process, intercostal muscles, pleura and lung movements were visualized from superficial to deep structures. 1 ml of 2% lidocaine was injected into the estimated needle entry area. Then, with the block needle the m. trapezius, mm. rhomboidei and erector spinae muscles were passed in order with the in-plane method and the needle was brought into contact with the transverse process. Fascial separation was confirmed with 1-2 ml of saline solution and the block was performed by injecting 20 ml of 0.375% bupivacaine. The distribution of the drug was confirmed by observing it with USG. |
| Measure | Description | Time Frame |
|---|---|---|
| Early postoperative Visual Analog Scale (VAS) scores | The postoperative pain level that evaluated with evaluated with VAS at 0, 15, 30 and 60 minutes. Patients were asked to indicate their pain on a scale where 0 represented "no pain" and 10 represented "unbearable pain". | First hour after surgery |
| Measure | Description | Time Frame |
|---|---|---|
| Additional opioid analgesic requirement in the postanesthesia care unit | Patients who scored 4 and above in the pain score were administered 10 mg meperidine. | First hour after surgery |
| Total opioid consumption after discharging from postanesthesia care unit |

| Pectoral Nerve Block | Procedure | The PECSI and PECSII blocks were applied concurrently. In patients who will undergo PECS II, sterile conditions were prepared with the arm on the side to be operated on in the supine position and 90 degrees of abduction. The lateral and pectoral branches of the thoracoacromial artery were visualized between the PM and Pm muscles at the level of the 4th rib under USG guidance. The blocking needle was directed between the PM and Pm muscles for PECS I, 1-2 ml of saline was injected to verify fascial spread, and 10 ml of 0.375% bupivacaine was applied. Afterwards, fascial spread was confirmed by injecting 1-2 ml of saline between the pectoralis minor muscle and the serratur anterior muscle, and PECS II was performed by injecting 10 ml of 0.375% concentration bupivacaine. The distribution of the drug was confirmed by observing it with USG. |

The PCA device, which was applied to the patients at the 60th minute postoperatively, was left for patient use until the 24th hour postoperatively. |
