Abstract

Objects: Our study examined the efficacy of a preemptive single-injection rectus sheath block in providing better early postoperative pain scores compared to general anesthesia alone. Methods: RCT with comparison study on 60 patients scheduled for open abdominal surgery with midline incision were divided two groups. Group A: consisted of patients who received an RSB using 0,6 ml/kg (both side) ropivacaine 0,375% under ultrasound guidance  and group B: no received RSB and. Both group were compared for VAS score, opioid consumption, analgesic requirements in surgical wards were recorded in postoperative days 0,1,2. Results: There were statistically significant differences in VAS score between the group A and B at all postoperative time points – 1hr, 2hr, 4hr, 6hr, 8hr (p < 0,01); 12 – 48 hr (p > 0,05). The cumulative 48 hrs morphine consumption after the operation was significantly lower in the group A than group B (28,14 ± 1,51 mg/ 42,26 ± 2,95 mg, p < 0,01). Conclusion: The ultrasound guided rectus sheath block used for abdominal surgery with midline incision could reduce postoperative pain scores and the amount of morphine consumption in 48 hours postoperative period.
