Comparison of the postoperative analgesic efficacy of Levobupivacaine alone and with Dexamethasone in ultrasound guided Quadratus Lumbor

This is a prospective randomised double blind study. Institutional ethical committee clearance obtained and informed consent would be taken from the patient. The total of 90 patients between the age 18 to 60 years of ASA grade 1 and 2 undergoing unilateral inguinal hernioplasty would be randomly divided into 2 groups of 45 each. After surgery under spinal anaesthesia, Group L will receive 0.25 % Levobupivane  20 ml + 1 ml 0.9 % normal saline and Group D will receive 0.25% 20 ml Levobupivacaine + 1 ml Dexamethasone (4 mg/ml) with a total of 21 ml in each group in ultrasound guided type 1 (lateral) Quadratus Lumborum block. Postoperatively, we will record and compare the duration of analgesia, total rescue analgesic (Tramadol) requirements and NRS pain scores in first 24 hours.
