    BackgroundPain is a common experience during nasoenteral catheterization. Although the procedure causes discomfort and distress to patients, procedural pain remains neglected and undertreated.ObjectiveTo evaluate the analgesic efficacy of the use of 10% lidocaine spray during nasoenteral catheterization.MethodA randomized, triple-blind trial of 50 patients was performed. The patients were randomly assigned to two groups: an intervention group (IG), in which 10% lidocaine spray combined with 2% lidocaine gel was used, and a control group (CG), in which a saline solution spray combined with 2% lidocaine gel was used. Pain and discomfort were assessed during and after nasoenteral catheterization using numerical rating scale (NRS) and the visual analogue scale (VAS), respectively.ResultsIntervention group participants reported lower pain scores during (0.20 ± 0.71 vs. 5.00 ± 2.84, p < .001; |d| = -0.677) and after (0.00 ± 0.00 vs. 2.80 ± 2.83, p < .001; |d| = -0.718) nasoenteral catheterization compared to the CG.ConclusionSpraying 10% lidocaine spray before nasoenteral catheterization was most effective for relieving discomfort and pain, with lower pain and discomfort recorded in NRS and VAS. Topical administration of 10% lidocaine spray is therefore a suggested measure for procedural pain relief related to nasoenteral catheterization.SignificanceThe use of 10% lidocaine spray was more effective in relieving procedural pain and discomfort during nasoenteral catheterization. Patients who received 10% lidocaine spray registered lower discomfort and pain scores than those from 2% lidocaine gel group; there were less complications among patients in the IG.© 2019 European Pain Federation - EFIC®.
