Abstract
Introduction

The emergence of flexible nasofibrolaryngoscopy in recent decades has facilitated the development of Otolaryngology and the nasofibrolaryngoscope has become an essential diagnostic tool for the otolaryngologist. However, its use is not without discomfort for the patient, which is why various options for topical anaesthesia have been proposed during the development of the technique.

Materials and methods

This was a prospective, double blind, crossover study in patients with no history of nasal disease, through which we compared the use of topical anaesthetic (Lidocaine)+epinephrine, oxymetazoline and placebo. Using a visual analogue scale, the degree of discomfort was assessed during each scan.

Results

We evaluated 18 patients, 10 women (55.6%) and 8 men (44.4%), with a mean age of 28±4 years. The degree of disturbance generated by the scan with the application of lidocaine–epinephrine was 1.94; with oxymetazoline it was 3.78, and with placebo, 4.61. When the lidocaine–epinephrine solution was compared with oxymetazoline, there was a statistical significance in favour of lidocaine–epinephrine (P<.05). When we compared the use of lidocaine–epinephrine with the placebo, the result was also statistically significant in favour of lidocaine–epinephrine (P<.05).

Conclusions

In this study we demonstrated that using lidocaine associated with epinephrine as a topical anaesthetic prior to flexible nasofibrolaryngoscopy decreases pain and feeling of discomfort for the patient. Consequently, we can recommend the use of topical nasal anaesthesia when performing this exploration.

Resumen
Introducción

El desarrollo de la otorrinolaringología en las últimas décadas se ha visto favorecido por la aparición de la nasofibrolaringoscopia flexible, la cual se ha convertido en una herramienta diagnóstica esencial para el otorrinolaringólogo. Sin embargo su uso no está exento de molestias para el paciente, razón por la cual diversas opciones de anestesia tópica se han propuesto durante el desarrollo de la técnica.

Materiales y métodos

Estudio prospectivo, doble ciego, cruzado, realizado en pacientes sin antecedentes de patología nasal a través del cual comparamos el uso de anestésico tópico (lidocaína) + epinefrina, oximetazolina y placebo. Mediante escala visual analógica se valoró el grado de molestias durante cada exploración.

Resultados

Fueron evaluados 18 pacientes, 10 mujeres (55,6%) y 8 hombres (44,4%), con una edad promedio de 28 años±4. El grado de molestia generado por la exploración con la aplicación de lidocaína más epinefrina fue de 1,94; oximetazolina 3,78; y placebo 4,61. Al comparar la mezcla lidocaína-epinefrina con oximetazolina obtuvimos significación estadística a favor de la lidocaína-epinefrina (p<0,05); al comparar el uso de lidocaína-epinefrina con placebo el resultado también fue estadísticamente significativo en favor de la lidocaína-epinefrina (p<0,05).

Conclusiones

En este estudio demostramos que el uso de la asociación de lidocaína con epinefrina como anestésico tópico antes de realizar la nasofibrolaringoscopia flexible disminuye el dolor y la sensación de molestia al paciente, por lo que se puede recomendar el uso de la anestesia tópica nasal a la hora de realizar esta exploración.
