Background :Laparoscopic surgery can induce moderate postoperative pain due to small keyholes on the abdominal wall. The oblique subcostal transversus abdominis plane block(OSTAP)has been used for postoperative pain management after abdominal surgery but
found ineffective. Aim: Our aim is to compare the efficacy of erector spinae block with OSTAP block for postoperative pain management after laparoscopic surgery. Material &Methods: Ninety patients, posted for laparoscopic surgery were divided into three equal groups of 30 each. Erector spinae plane block was given in the ESP group. Oblique subcostal transversus abdominis plane block was given in the OSTAP group and IV analgesics were administered in control group for postoperative pain management. Postoperative rescue analgesic (paracetamol) consumption,time to 1st rescue analgesia request, numerical rating score (NRS), and any
complications in 1st 24 hrs between the three groups were recorded and analyzed. Statistical Package for the Social Sciences version 21.0 was applied for statistical analysis. Descriptive statistics were expressed as mean ± standard deviation.Result:Postoperative rescue analgesia (paracetamol) consumption was 2.2± 0.77gm in ESP group , 2.91 ±0.19gm in OSTAP group and 4.17± 0.66gm in control group which was statistically significant. Time to 1st rescue analgesia request was 374.16±30.56 mins in ESP group, 294.62±43.19 mins in OSTAP group and 152.6± 37.45mins in control group which was statistically significant.
Conclusion:Ultrasound guided ESP block is more effective in postoperative pain management after laparoscopic surgery when compared to OSTAP group and control group.
