RESULTS
Following the assessment of subjective and objective parameters, the values obtained were subjected to statistical analysis.
Table 1 shows Comparison of mean LA Volume (in ml) & Duration of Anaesthesia & Surgery (in Mins) between Test & Control sites using Student Paired t Test. The duration of anesthesia was significantly greater (p<0.001) in the ropivacaine group when compared to the lignocaine group with a mean difference of 193.33.
Table 2 shows the quality of anesthesia obtained at test and control sites and was assessed using a rating scale. In all the surgical sites treated, areas anesthetized with ropivacaine patients reported a score of 3 or lesser while only 70% in the lignocaine group reported a score of 3 or lesser. The above observations infer that ropivacaine was superior to lignocaine as far as quality of anesthesia was concerned.
Table 3 shows the comparison of VAS scores at different time intervals/points between two groups.The scores in the ropivacaine group were consistently lower than the lignocaine group.The difference in scores were statistically significant in favour of the ropivacaine group.
