Box andrnwhisker plot were used to show a median pain score differences between groups and statisticalrnsignificance were sated at p value < 0.05 with a power of 80%.rnResults: The comparison of data showed that during recovery room (PACU) time the medianrnpostoperative pain score(NRS) were 3 in exposed group and 5 in non-exposed group (p=0.002).rnThe comparison also shows lower median pain score 2 compared to 4 at 3rd post-operative timern(p
