comparison of erector spinae plane block and quadratus lumborum block for postoperative analgesia in total abdominal hysterectomy.

44 patients posted for elective abdominal hysterectomy will be selected for the study. they will be divided by computer generated ramdom number method in two equal groups of 22 each. Group A will receive usg guided  Quadratus lumborum block.bilateraly   in lateral position before operation with 20 cc of 0.25% of bupivacaine  on each side. Time of block placement will be noted. Similarly Group B will receive Usg Guided Erector Spinae Plane Block bilateraly  in lateral position before operation with 20  cc 0.25% bupivacaine on each side and time of block placement will be noted. Abdominal hysterectomy will be carried out as per routine procedure under general anaesthesia  and surgical duration will be noted . In postoperative period patients will be observed for 24 hrs . Time of first analgesic requirement will be noted in both groups and will be compared for statistical difference . Also total analgesic required to keep VAS <4  in 24 hrs will be noted in both the groups and calculatedted to see statistical difference in both the groups.

Also any adverse effect of block will be noted.
