A comparison of xylometazoline (Otrivine) and phenylephrine/lignocaine mixture (Cophenylcaine) for the purposes of rigid nasendoscopy: a prospective, double-blind, randomised trial.
OBJECTIVE
To evaluate if phenylephrine-lignocaine mixture (Cophenylcaine) nasal spray performs better than xylometazoline (Otrivine) spray for the purposes of out-patient rigid nasendoscopy preparation.


METHODS
Prospective, double-blind, randomised trial comparing visual analogue scores for out-patients receiving either phenylephrine-lignocaine mixture or xylometazoline, prior to undergoing rigid nasendoscopy as part of their assessment.


METHODS
Seventy-three patients requiring rigid nasendoscopy as part of their assessment were recruited to the study from Raigmore Hospital's out-patient clinic. These patients were randomised to receive a nasal spray comprising either phenylephrine-lignocaine mixture or xylometazoline, 10 minutes prior to rigid nasendoscopy. Double-blinding was adopted. After the procedure, the patient and the doctor independently completed separate visual analogue score-based questionnaires regarding the pain of the procedure and the ease of the examination, respectively.


RESULTS
Analysis of the data using standardised statistical methods demonstrated that the phenylephrine-lignocaine mixture did not perform better than xylometazoline, to any statistically significant extent.


CONCLUSIONS
Phenylephrine-lignocaine mixture is considerably more expensive and has potentially more side effects than xylometazoline. These study findings suggest that it is difficult to justify the use of phenylephrine-lignocaine mixture over xylometazoline, for nasal preparation prior to rigid nasendoscopy.
