Evaluation of the Efficacy of Paracetamol in the Control of Pain After Adenotonsillectomy in the Pediatric Population.

Introduction Adenotonsillectomy is a common surgical procedure in otolaryngology. Over the years, several techniques have been developed and modified in order to reduce mortality and morbidity. Postoperative pain control remains controversial. The aim of this study was to evaluate the efficacy of paracetamol alone in the control of postoperative pain. Methods A prospective study was conducted between May 2018 and February 2019, including 76 pediatric patients (age < 18 years), who underwent adenotonsillectomy. The surgeries were performed by the lead author with the same surgical technique. Patients were evaluated one week and one month after surgery through the application of the visual analog pain scale and the number of days of pain was assessed by the need for medication. Results Seventy-six total adenotonsillectomy were performed, with a total of 152 tonsils removed. The majority of patients were male (n=39, 51.3%), with an average age of 6.9 years (min 5, max 15 years). The most frequent surgical indication was sleep breathing disorders, present in 86.9% of the cases. The average duration of postoperative pain was 3 days, with no significant difference between groups (p>0.05). The average intensity of postoperative pain was 3.36 and was higher in patients with infectious criteria as surgical indications (p<0.05). Postoperative bleeding occurred in 3.9% (n=3) of the children, self-limited, without the need for readmission or surgical revision. Conclusion Pain after adenotonsillectomy was more intense in patients undergoing surgery for infectious criteria. Paracetamol used in monotherapy has shown safety and efficacy in controlling postoperative pain.
