NCT05494281

Brief Summary

Chronic postoperative pain (CPP) remains a disturbing and obscure clinical problem. The hypothesis of this trial is that a peripheral block of the serratus anterior plane block type preoperatively after a modified radical mastectomy makes it possible to reduce the intensity and incidence of chronic post-surgical pain in breast cancer.

Outcome Measures

Primary Outcomes (2)

  • Chronic postoperative pain at 3 months

    A question will be asked to patients : "Throughout our lives, most have had pain (like headaches, sprains and toothaches). Have you had pain other than these types of pain on a daily basis since your surgery? " The answer "yes" or "no" will determine the outcome

    3 months after surgery

  • chronic postoperative pain intensity

    Pain intensity of patients was evaluated by Numerical Rating Scale, rating from 0 (no pain) to 10 (extreme pain) in order to evaluate the effect of Serratus Anterior Plane Block in preventing chronic pain

    3 months after surgery

Secondary Outcomes (3)

  • Chronic Pain intensity and quality

    3 months after surgery

  • Neuropathic pain screening

    3 months after surgery

  • Morphine consumption

    0-24 hours after operation

Study Arms (2)

Placebo

EXPERIMENTAL
Procedure: Serratus Anterior Plane Block with saline solution

Serratus anterior plane block

EXPERIMENTAL
Procedure: Serratus Anterior Plane Block with local anesthetic

Interventions

A deep analgesic block of the Serratus anterior plane block (SAPB) type by echo-guided lateral approach will be performed by An 8-13 Mhz high frequency linear ultrasound probe witch will be located cranio-caudally, transversely to the 3rd and 4th intercostal space on the mid-axillary line while patients are supine with the ipsilateral upper limb raised to 90°. Once the landmark anatomical structures have been identified (upper rib, lower rib, pleural line, Serratus muscle, superficial structures), the puncture will begin Under aseptic conditions, an 80 mm 22 gauge needle will be inserted into the "in-plane" view of the ultrasound probe. When the needle has reached the plane under Serratus between the Serratus muscle and the intercostal muscle opposite the lower edge of the upper rib, 30 ml of 1% Lidocaine will be administered.
