The Impact of Antibiotics on Co-morbidities Post Tonsillectomy: A Prospective, Double-Blind, Randomized Study

Background: Adenotonsillectomy is one of the most frequent operations performed in hospitals worldwide. The aim this study is to investigate further the impact of antibiotics on co-morbidities post tonsillectomy. Methods: This prospective double blinded randomized controlled study was conducted at the department of otolaryngology in a tertiary care hospital where 300 tonsillectomy operations are performed each year. All Patients aged 2 years and older who were admitted for elective tonsillectomy from January 2012 to December 2012 were included in this study. Results: From the 128 patients enrolled in the study, 70 belonged to Group A (Intervention) and 50 to Group 2 (Control). There was no statistically significant difference in the post-operative oral intake, fever in the first post operative day, degree of stress, secondary bleeding, otalgia, fever at home, and day of return to regular diet between the two groups. Conclusion: Although some studies showed that antibiotic use was beneficial in reducing morbidities post tonsillectomy, it is advisable for otolaryngologist to re- evaluate current practice taking into consideration bacterial resistance to antibiotics, adverse effects and cost benefit ratios. The use of antibiotics in post tonsillectomy patients will remain crucial in some selected cases.
