NCT06758765

Brief Summary

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:

  • Whether these two different block procedures will create a difference in postoperative pain scores.
  • Comparison of total opioid consumption during the 24-hour postoperative period. Our study included patients who were female, who were going to undergo elective breast-conserving surgery between March 2022 and August 2022.

Outcome Measures

Primary Outcomes (1)

  • 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

Secondary Outcomes (3)

  • Additional opioid analgesic requirement in the postanesthesia care unit

    First hour after surgery

  • Total opioid consumption after discharging from postanesthesia care unit

    Between 1-24 hours after surgery

  • Visual Analog Scale (VAS) during 24 hours follow-up after surgery

    1th, 4th, 6th, 12th, and 24th hours postoperatively

Study Arms (2)

ESP group

EXPERIMENTAL

The group that received erector spinae plane block

Procedure: Erector Spinae Plane Block

PECS group

EXPERIMENTAL

The group that received PECSI-II blocks

Procedure: Pectoral Nerve Block

Interventions

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.

ESP group

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.
