About this study

After being informed about the study and potential risks, written consent was obtained from all patients.Patients who meet eligibility requirements will be randomized in a 1:1 ratio to erector spinae plane block and rhomboid intercostal block.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Patients who will undergo unilateral breast-conserving surgery (BCS) or modified radical mastectomy (MRM) with or without axillary lymph node dissection
  • Patients undergoing elective surgery
  • ASA (American Society of Anesthesiologists) physical status classification I-III

Exclusion criteria

  • Use of anticoagulants
  • Allergy to the medications to be used
  • Patients who use analgesic drugs due to a history of chronic pain
  • ASA (American Society of Anesthesiologists) physical status classification IV-V
  • Patients with psychiatric disorders

  • Presence of deformity in the patient's spinal, paraspinal and area where the block will be applied
  • The patient does not accept the block application or cannot cooperate with the patient

Treatment and study plan

Erector spinae plane block

Other

Ultrasound(US)-guided erector spinae plan block(ESP) with 20 ml 0,25% bupivacaine at T4 vertebra level will performe preoperatively to all patients in the ESP group.

Rhomboid intercostal block

Other

Ultrasound(US)-guided rhomboid intercostal block(RIB) with 20 ml 0,25% bupivacaine at T5-T6 vertebra level will performe preoperatively to all patients in the RIB group.

Primary outcomes

  1. Morphin Consumption

    Time frame: during postoperative 24 hours

    Patients in both groups will provide with intravenous patient-controlled analgesia device containing morphine for postoperative analgesia

Secondary outcomes

  1. Numerical Rating Scale(NRS)

    Time frame: during postoperative 24 hours

    A numerical rating scale(NRS) requires the patient to rate their pain on defined scale.For example , 0-10 where 0 is no pain and 10 is the worst pain imaginable.
