Abstract

The aim of this study was to determine whether cough sensitivity is changed after adenoidectomy in atopic children with chronic cough. 21 Children having symptoms of chronic cough and adenoid hypertrophy verified by nasal fiberoptic endoscopy were submitted to cough sensitivity measurement before and after adenoidectomy. Their pulmonary function was within normal range. Concentrations of capsaicin causing two (C2) and five coughs (C5) were reported. Children' (14 boys and 7 girls, mean age 6,52 yrs) cough sensitivity (geometric mean, with 95% CI) for C2 was preoperatively (before adenoidectomy) 19.95 (9.95-39.98) micromol/l vs. children' C2 postoperatively 14.04 (7.16-27.55) (P = .083 for Wilcoxon paired two sample test). Children' C5 was preoperatively 86.26 (39.25-189.57) micromol/l vs. C5 postoperatively 95.23 (46.33-195.75) micromol/l (P = .794 for Wilcoxon paired two sample test). We conclude that cough sensitivity for C2 and C5 was not significantly changed after adenoidectomy in atopic children with chronic cough.
