Abstract

Aim:There is little information on the effect of topical anaesthetics on patient comfort during sigmoidoscopy, We evaluated this treatment in a randomized study.Method:One hundred and forty-six patients undergoing sigmoidoscopy were randomly allocated to three groups including vaseline (group I, n = 49), lidocaine gel (2%) (group II, n = 51) and a cream of lidocaine (2.5%) plusprilocaine (2.5%) (group III, n = 46)applied to patients immediately before sigmoidoscopy. Haemodynamic monitoring was carried out during theprocedure. Pain was assessed using a visual analogue scale (VAS) and anxiety levels by the State-Trait Anxiety Inventory (STAI-I and STA-II).Results:Medianpre-procedural STAI-I scores were 45, 46, 40.5 and median post-procedural STAI-I scores were 35, 34, 33.5 in groups I, II and III. There was no statistical difference between the groups in terms of STAI-I and II scores. However, post-procedural STAI-I scores were significantly lower thanpre-procedural values in each group (P < 0.001). There was no significant difference in the VAS scores between the groups. The evaluation within the groups revealed statistically higher VAS scores during theprocedure when compared topre and post-procedural scores (P < 0.001).Conclusion:Anal application of topical anaesthetic does not have an impact on patient comfort during sigmoidoscopy.
