Clinical effect of compound lidocaine cream on oropharyngeal flora under general anesthesia

Abstract

To observe the effect of compound lidocaine cream on oropharyngeal flora under general anesthesia, the front-end tracheal tube or laryngeal mask was coated with 410 cases under general anesthesia were chosen as endotracheal intubation group (T) and Laryngeal mask group (L) from Jan, 2022 to June, 2022. Both were separately grouped into blank control (M), liquid paraffin oil (P) and Compound lidocaine cream (C). Based on the grouping, patients’ throat swab samples were collected for bacterial culture through tracheal catheter. Oral normal flora and pathogenic bacteria from M and P were compared and P >0.05 was considered statistically non-significant. By comparison of C, T and L group, their oral normal flora and pathogenic bacteria were obviously restrained. In conclusion, compound lidocaine cream was coated on tracheal tube or laryngeal mask for patients under general anesthesia. This method will be helpful to improve oral problems from pathogenic bacteria and also to inhibit oral normal flora.
