Implication

Randomized trial compares analgesic effectiveness of ESP and RISS blocks in patients undergoing modified radical mastectomy, suggesting RISS as an alternative.

Key Points

To compare the analgesic efficacy of erector spinae plane block with rhomboid intercostal subserratus block following modified radical mastectomy.
Randomized control trial with 40 ASA physical status I-II patients aged 18-65 years undergoing modified radical mastectomy.
Patients received either ESP block with 20 ml bupivacaine or RISS block with 40 ml bupivacaine.
Primary outcome was total postoperative fentanyl consumption over 24 hours; secondary outcomes included first rescue analgesic time and NRS scores.
Fentanyl requirement in the ESP group was 79.50 ± 35.46 μg; for the RISS group, it was 80.50 ± 39.79 μg (P = 0.88), indicating no significant difference.
Intraoperative fentanyl requirement was similar for both groups (P = 0.11).
No significant differences in first rescue analgesia time or NRS scores at various intervals (all P > 0.05).
