Brief Summary

Nowadays, the incidence of breast cancer is the first number of malignant tumors, and the primary treatment method is surgery.With the development of medical technology and concept, radical mastectomy combined breast reconstruction are becoming more and more popular.But the reconstruction caused greater trauma and more severe postoperative pain.ESPB is a new nerve block method which thought to reduce pain after thoracic and breast surgery.However, there are few studies on radical mastectomy combined breast reconstruction. So, this randomized controlled study is conducted to explore its impact on postoperative pain and thus provide more data guidance for clinical.

Outcome Measures

Primary Outcomes (1)

  • Post-operative acute pain score at 6 hours

    11-point numerical rating scale(0=no pain, 10=worst pain) at 6th hour following the surgery

    6 hours After surgery

Secondary Outcomes (4)

  • Postoperative quality of recovery score

    24 to 72 hours after the surgery

  • Post-operative acute pain score

    1h, 12h,24, 48h, 72h after the surgery, separately.

  • Cumulative opioid consumption after surgery

    48 hours after the surgery

  • AUC of postoperative pain score

    72 hours after the surgery

Other Outcomes (3)

  • Number of patients with nausea and vomiting

    24 to 72 hours after the surgery

  • Intraoperative hemodynamic data

    During the whole surgery process.

  • The number of patients receiving rescue analgesia.

    24 to 72 hours after the surgery

Study Arms (2)

Erector spinae plane block group

EXPERIMENTAL

Before surgery, an ultrasound-guided ESPB was performed. 30 mL of 0.375% ropivacaine and 0.5μ g/kg dexmedetomidine mixture was injected in the interfascial plane between rhomboideus major and erector spinae muscle. Ropivacaine is produced by AstraZeneca AB under the trade name of Naropin, and the specifications are 75 mg / 10 ml. Dexmedetomidine is produced by HengRui medical China and the specifications are 100μg / 1 ml。

Procedure: Erector spinae plane block

Control group

NO INTERVENTION

Control groups do not receive additional analgesia.

Interventions

In the ESPB group, the patients were placed in the lateral decubitus position. The ultrasound probe was located in longitudinal orientation at the level of the T4 spinous process and then placed 3 cm laterally from the midline to the side involved in the surgery. The ultrasound landmarks, T4 transverse process, and the overlying trapezius, rhomboideus, and erector spinae muscles, were identified. Under aseptic conditions, an 80-mm 21-gauge block needle was inserted in-plane at an angle of 30-40° in the cranial-to-caudal direction until the tip contacted the T4 transverse process.After the hydrodissection with 2-3 mL of isotonic saline solution confirmed the correct needle tip position, the intermixture was injected in the interfascial plane between rhomboideus major and erector spinae muscle. Local anesthetic spread in a fascial longitudinal pattern deep to the erector spinae muscle was visualized using ultrasound guidance.
