Abstract

Objective:
• Onset of Anesthesia.
• Duration of Analgesia and Anesthesia.
• Quality of Anesthesia.
Methods: This prospective study was conducted in the Department during one year period of June 2012 – 2013 by selecting
random 75 patients. The included criteria patients were randomly allotted into three groups of 25 each and were randomly
allocated to Group I, Group II and Group III to receive local anesthesia followed by intraoral administration of Ropivacaine
and the objective criteria was evaluated.
Results: The ANNOVA test was employed to assess the impact of each concentration, and subsequent post hoc testing was
conducted to make group comparisons. Significance was denoted by P values of < 0.05 and highly significant differences by
P values of < 0.001. The total mean onset duration for subjective symptoms was 0.75% (1.240.52± minutes), 0.50% (1.801±
minute), and 0.20% (2.680.90± minutes). Objective symptoms had onset times of 0.75% (2.660.65± minutes), 0.50% (3.91.32±
minutes), and 0.20% (6.841.26± minutes). The onset of these symptoms was notably faster with the 0.75% concentration
compared to the other two concentrations.
Conclusion: The mean anesthesia durations (in hours) were maximum in case of 0.75% (8.021.11± hrs) in comparison to
other groups. The mean analgesia durations were maximum in case of 0.75% too (4.493.29± hrs). Nine patients in the 0.75%
concentration and eight patients in the 0.50% concentration reported no pain after the procedure, while 25 patients in the 0.20%
concentration experienced pain. The duration was significantly different for anesthesia (p=0.001) but not for analgesia (p=0.09)
