Abstract
NORIEGA-SALAS, Ana Lorena; SANCHEZ-LOPEZ-LOPEZ, Miguel Ángel; ESPERON LORENZANA, Guadalupe Iris and TREJO SUAREZ, José. Application of 2% lidocaine on subcutaneous cell tissue of clean-contaminated and contaminated surgical wounds to diminish the incidence of infection. Cir. gen [online]. 2011, vol.33, n.3, pp.180-184. ISSN 1405-0099.
Objective: To demonstrate that the application of 2% lidocaine on the subcutaneous tissue of surgical clean-contaminated and contaminated wounds diminishes the infection risk. Setting: Hospital General ''Xoco'', second level health care hospital. Design: Non-controlled, simple, randomized clinical assay. Statistical analysis: Fisher's exact test, and Student's t test. Patients and methods: A simple randomized assignation was used for two groups of patients. One group of 11 patients was applied 10 ml of 2% lidocaine on the subcutaneous tissue of the wound, and the other group of 11 patients received 0.9% saline solution; all 22 patients had clean-contaminated and contaminated surgical wounds. Surgical wounds were checked 7 days after surgery, and the studied variables were age, gender, presence or not of infection on the superficial surgical site. Results: No infection was observed in the 11 patients in whom 2% lidocain had been applied, whereas 3 patients from the 0.9% saline solution group presented infection of the surgical wound, with a statistically significant difference of P < 0.05 between both groups. Conclusion: A statistically significant diminution was observed in the frequency of infection at the surgical clean-contaminated and contaminated wounds when applying 2% lidocaine, as compared to not applying it.
