Immediate effects of a rhino-pharyngeal clearance protocol in nasal obstruction and middle ear condition of children under 3 years of age with upper respiratory infections: A randomized controlled trial

INTRODUCTION AND OBJECTIVES

Children up to 2 years old are at high risk of respiratory infections and nasal irrigation is often prescribed. Yet, to date there is no sufficient knowledge about its immediate effects on the nasopharynx and middle ear. Therefore, this study aimed to analyze the effect of a rhino-pharyngeal clearance intervention protocol on nasal obstruction and middle ear condition in children under 3 years of age with URTI.

MATERIALS AND METHODS

Randomized controlled trial in a day-care centre of Porto, including 44 children randomized to Intervention Group (IG) and Control Group (CG). Nasal auscultation and tympanometry were performed at baseline (M0) as well as after the intervention (M1), which consisted of nasal irrigation (NaCl .9%) followed by a forced nasal inspiration in the IG, and after 30min of normal activities, in the CG.

RESULTS

In M1 there was a lower frequency of children classified as having an obstructed nasal sound in the IG when compared to the CG (IG=33.3%; CG=68.4%; p=0.042). We also observed an improvement of mean peak pressure (PP) in the IG (Left ear: M0=-124daPa; M1=-92daPa; p=0.022. Right ear: M0=-102daPa; M1=-77daPa; p=0.021), which was not observed in the CG (Left ear: M0=-105daPa; M1=-115daPa; p=0.485. Right ear: M0=-105daPa; M1=-131daPa; p=0.105). There were no significant results concerning the compliance of the tympanic membrane.

CONCLUSIONS

The rhino-pharyngeal clearance improved the nasal obstruction and PP of the middle ear of children under 3 years of age with URTI.

Caregivers' education vs rhinopharyngeal clearance in children with upper respiratory infections: impact on children's health outcomes

Upper Respiratory Tract Infections (URTI) are very common in children having no effective pharmacological treatment. This study aimed to compare the effect of caregivers' health education regarding children's respiratory infections and the effect of a rhinopharyngeal clearance protocol in children with URTI. A factorial trial was conducted in 138 children up to 3 years, attending day-care centres. Children were distributed into four groups: control group (CG) (n = 38); education group (EG) (n = 34); intervention group (IG) (n = 35); and education and intervention group (E + IG) (n = 31). A Diary of Records was kept by caregivers during 1 month. There were significant differences between groups concerning: Lower Respiratory Tract Infections (CG = 29.4%; EG = 10.7%; IG = 3.8%; E + IG = 0.0%; p = 0.014); acute otitis media (CG = 32.4%; EG = 7.1%; IG = 11.5%; E + IG = 7.7%; p = 0.014); medical consultations (CG = 70.6%; EG = 42.9%; IG = 38.5%; E + IG = 30.8%; p = 0.021); antibiotics (CG = 44.1%; EG = 7.1%; IG = 23.1%; E + IG = 15.4%; p = 0.006); days missed from day-care (CG = 55 days; EG = 22 days; IG = 14 days; E + IG = 6 days; p = 0.020); days missed from employment (CG = 31 days; EG = 20 days; IG = 5 days; E + IG = 1 day; p = 0.021); and nasal clearance techniques (CG = 41.4%; EG = 78.6%; IG = 57.7%; E + IG = 84.6%; p = 0.011).

CONCLUSION

This study showed that the most positive impact on children's health outcomes occurred when combining health education of caregivers, regarding children's respiratory infections, with a rhinopharyngeal clearance protocol in children with URTI. What is Known: • Upper Respiratory Tract Infections are very common in children but still do not have an effective pharmacological treatment. • This generates a great burden of disease for the child and families, increasing the use of antibiotics. What is New: • This study is the first one that aims to analyze the effects of caregivers' health education in comparison to non-pharmacological intervention in acute respiratory infections in children. • It shows a positive impact on children's health outcomes, empowering caregivers regarding their child's health and reducing the burden of disease, medical consultations and the use of antibiotics.
