Changes in Cough Reflex Sensitivity in Children After Removal of Hypertrophied Adenoid Tissue

Figures & data

Table 1 Cough reflex sensitivity  (CRS) - C2 and C5 values, Hull Cough Questionnaire and AH subjective symptoms questionnaire before and after AT

C2 (µmol/L) before AT	31.86 (12.98–78.18)	P=0.064
C2 (µmol/L) after AT	11.97 (6.16–23.26)
C5 (µmol/L) before AT	234.91 (97.19–567.77)	P=0.022
C5 (µmol/L) after AT	69.13 (29.08–164.35)
Hull Cough Questionnaire before AT	6 (8–17)	P=0.0005
Hull Cough Questionnaire after AT	0 (3–5)
AH subjective symptoms questionnaire before AT	15 (26–28)	P=0.0005
AH subjective symptoms questionnaire after AT	2 (4–12)

Notes: Data are shown as median (lower quartile – upper quartile).

Abbreviations: AH, adenoid hypertrophy; C2, concentration of capsaicin causing two coughs; C5, concentration of capsaicin causing five coughs; AT, adenoidectomy.

Figure 1 Cough reflex sensitivity (CRS) – C2 values before and after endoscopic adenoidectomy in children with chronic cough. C2, concentration of capsaicin causing at least two coughs (P=0.064).

Figure 2 Cough reflex sensitivity (CRS) – C5 values before and after endoscopic adenoidectomy in children with chronic cough. C5, concentration of capsaicin causing at least five coughs (P=0.022).
