Randomized Controlled Trial
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.
During flexible fibreoptic bronchoscopy through the nasal route, anaesthesia of the nasal passage is achieved by lignocaine gel application by a slip-tip syringe or with the help of a cotton tip swab. No studies in existing literature have compared the two techniques in terms of efficacy. ⋯ 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.
