Comparison of Local Anaesthetic Efficacy of Tramadol Versus Lignocaine for Extraction of Tooth Under Supraperiosteal Infiltration.

BACKGROUND

Tramadol has been shown to have a local anaesthetic effect when used as infiltration anaesthesia.

METHODS

The local anaesthetic efficacy of tramadol was compared with that of lignocaine for the extraction of teeth in terms of their onset of action, duration of action, intraoperative pain, post-operative analgesic effect and adverse reactions. Apart from this, incidence of allergic reaction was also recorded for both the drugs. A total of 100 patients were divided into two groups randomly. Each patient was assigned to receive either a maximum of 2 ml of 5% tramadol (Supridol 50 mg, Neon laboratories), Group T ( = 50), as a local anaesthetic solution for extraction of maxillary premolar for orthodontic reason under supraperiosteal infiltration following strict aseptic precaution or a maximum of 2 ml of 2% lignocaine (Lox 2%, Neon laboratories), Group L ( = 50), in a double-blinded fashion.

RESULTS

In group T, the mean subjective onset of action was 33.66 s, while in group L it was 33.06 s ( = 0.881). In group T, the mean objective onset of action was 3.04 min, while in group L it was 3.18 min ( > 0.05). The mean duration of action in group T was 55.60 min, while in group L it was 57.50 min ( = 0.432). Only 2 patients in group T and 1 patient in group L had nausea ( = 0.245).

CONCLUSION

We conclude that 5% tramadol has a local anaesthetic efficacy similar to 2% lignocaine but is comparatively a weaker agent.
