Influence of dietary and physical activity restriction on pediatric adenotonsillectomy postoperative care in Brazil: a randomized clinical trial.

Introduction: Although culturally food and physical activity restriction are part of the routine postoperative care of many Brazilian surgeons, current evidences from other countries support no such recommendations.

Objective: To determine whether dietary and physical restriction effectively lead to a decrease on postoperative complications of adenotonsillectomy in children when compared to no restriction.

Methods: We have designed a randomized clinical trial comparing two intervention: no specific counseling on diet or activity (Group A), and restriction recommendations on diet and physical activities (Group B). Caregivers completed a questionnaire on observed pain, diet and activity patterns, and medications administered. Parameters were compared at the 3rd and at the 7th postoperative day between intervention groups.

Results: We have enrolled a total of 95 patients, 50 in Group A and 45 in Group B. Fourteen patients were lost to follow up. Eventually, 41 patients in group A and 40 in Group B were available for final analysis. Mean age in months (A=79.5; SD=33.9/B=81.1; SD=32.6) and sex (A=58% male; B=64.4% male) were equivalent between groups. Pain, evaluated through visual analog scale in the 3rd (A=2.0; IQR 1-6/B=4.5; IQR 2-6; p=0.18) and in the 7th (A=1.0; IQR 1.0-4.5/B=2.0; IQR 1.0-4.7; p=0.29) postoperative days, was not different between groups, as was the amount of analgesics administered. Dietary and physical activity patterns also showed no statistically significant differences between groups.

Conclusion: Dietary and activity restriction after adenotonsillectomy does not seem to affect patients' recovery. Such information may impact considerably on the social aspects that involve a tonsillectomy, reducing the working days lost by parents and accelerating the return of children to school.
