Abstract

The study was conducted to assess the effect of lignocaine and tramadol on healing of Staphylococcus aureus infected incision wound in rats. Incision wounds were created in three groups consisting of six rats in each group. The rats were infected with Staphylococcus aureus inoculum and the incision was closed. The rats were treated according to their group– Group I(Normal saline), Group II (2% Lignocaine) and Group III (5% Tramadol). All the drugs were applied topically, once a day for 10 days. The parameters measured to evaluate the wound healing was breaking strength, Colony Forming Units/ mL (CFU/ mL) of the tissue and histopathological examination. Data analysis was by one-way (Analysis of Variance) ANOVA followed by post hoc Tukey’s test.A significant difference (p<0.05 vs control) in the breaking strength and CFU/mL of tissue was observed between the control GroupI and the test groups,Group II(2%lignocaine) and Group III(5% tramadol) when the drugs were used topically.Histopathological study did not show much difference in the morphology between the control and other groups. This study suggests that lignocaine and tramadol donotimpede healing of infected incision wound
