EVALUATION OF ANALGESIC EFFICACY OF BUPIVACAINE AND ROPIVACAINE GIVEN THROUGH LANDMARK GUIDED ERECTOR SPINAE PLANE BLOCK FOR POST-OPERATIVE PAIN RELIEF IN PATIENTS UNDERGOING LAPAROSCOPIC CHOLECYSTECTOMY

Introduction: Postoperative pain after Laparoscopic cholecystectomy can leads to increased consumption of opioids with subsequent nausea, delayed bowel function and prolonged postoperative recovery. Landmark guided erector spinae plane block is safe, easy to perform and less time consuming. Method: 60 patients between aged 18-60 years, ASA physical status I, II and III undergoing Laparoscopic Cholecystectomy were divided into two groups: Group B (Bupivacaine) and Group R (Ropivacaine). Before induction of general anesthesia, bilateral erector spinae block was performed at the level of thoracic 9th vertebrae. General anesthesia was given with standard induction and maintenance technique. Total duration of post-operative analgesia i.e. time until request of rescue analgesia, frequency of additional analgesics in first 24 hr. were noted. Result: VAS score was found lower in group R (Ropivacaine) as compared to group B (Bupivacaine). Total duration of analgesia with time until request of analgesia was longer in group R as compared to group B. In terms of post-operative VAS score and post-operative analgesia and additional analgesic requirement, group R was better as compared to group B. Conclusion: As a promising novel post-operative pain relief related procedure, Landmark guided Erector spinae plane block is simple, safe,easy to perform and most effective analgesic technique as part of multimodal analgesia for laparoscopic Cholecystectomy patients.
