About this trial
This study aims to compare the costotransverse foramen block with erector spinae plane block in modified radical mastectomy.

Treatments tested in this trial
Costotransverse foramen block
Other interventionPatients will receive an ipsilateral ultrasound-guided costotransverse foramen block with injection of 20 ml bupivacaine 0.25%.
Erector spinae plane block
Other interventionPatients will receive an ipsilateral ultrasound-guided erector spinae plane block with injection of 20 ml bupivacaine 0.25%.
Treatment groups
Trial outcomes
Primary outcomes
Total morphine consumption
If the numeric rating scale (NRS) is ≥ 4, an IV morphine dose (3 mg) will be provided Paracetamol 1 gm and ketorolac 30 mg will be administered every 8 hours postoperatively.
Secondary outcomes
Degree of pain
Each patient will be instructed about postoperative pain assessment with the numeric rating scale (NRS) score. NRS (0 represents "no pain" while 10 represents "the worst pain imaginable"). NRS score will be recorded in post-anesthesia care unit (PACU) then at 1, 6, 12, 18, 24, and 48 hours postoperatively.
Time to first request of rescue analgesia
Time to first request of rescue analgesia will be recorded from the end of surgery till first dose of morphine administrated.
Intraoperative fentanyl consumption
Intraoperative fentanyl consumption will be recorded.
Mean arterial pressure
Mean arterial pressure will be recorded immediately before induction of anesthesia, 15 min after performing the block incision and at 20-minute intervals intraoperatively, and then hourly till 4 hours postoperatively.
