Utility of nasal application of lignocaine gel using cotton tip swab versus squirting with slip-tip syringe for transnasal fibreoptic bronchoscopy: a pilot randomised controlled trial.

Application of 2% lignocaine gel by slip-tip syringe and cotton tip swab are equivalent in terms of observed and narrated pain experienced by patients, frequency of epistaxis and nasal blocks. Vision was better preserved in the cotton tip swab group.
