Ultrasound (USG) guided Rhomboid Intercostal Subserratus(RISS) block and Rhomboid Intercostal Block (RIB) are two novel inter‐fascial plane blocks providing satisfactory analgesia postoperatively. Our aim was to investigate the effectiveness of these blocks following thoracic and upper abdominal surgeries. 90 patients who had ASA (American Society of Anesthesiologists) Grade‐I and II between age 20‐80 years undergoing thoracic and upper abdominal surgeries were allocated randomly in three groups and analyzed: RIB group (20ml 0.25% bupivacaine+8mg dexamethasone, RISS group (40ml 0.25% bupivacaine+8mg dexamethasone), whereas in group C no block was administered. The primary outcomes included assessment of time to first rescue analgesia, VAS scores and fentanyl consumption for 24 h following surgery. Assessment of hemodynamic parameters, patient and surgeon satisfaction scores, sedation scores and post operative nausea and vomiting (PONV) incidence were included in the secondary outcomes. The first rescue analgesic request, VAS Scores and fentanyl consumption were lower significantly in RIB and RISS groups at 0.5, 1, 1.5, 2, 4, 6, 8, 10, 12, 18 and 24 hours postoperatively in comparison to group C (P‐value‐ RISS/C‐ 0.00, RIB/C‐0.01) whereas it is greater in RIB group in comparison to RISS group with P value 0.01. Both blocks effectively reduced post operative pain, but we observed that RISS more efficacious than RIB as it produced better analgesia in terms of lower VAS Scores, increased time to first rescue analgesia and reduced postoperative fentanyl consumption.
