The objective of the present review and meta‑analysis was to evaluate the efficacy of bupivacaine during tonsillectomy in terms of reducing the mean operative procedure duration, post‑operative pain and the onset of post‑operative morbidities. The Preferred Reporting Items for Systematic reviews and Meta‑Analyses guidelines were followed to perform a systematic literature search using the MEDLINE, Scopus, EMBASE and CENTRAL databases. The present meta‑analysis sought to evaluate the efficacy of bupivacaine administered during tonsillectomy as compared to the administration of normal saline. The efficacy of the intervention was evaluated based on pain scores using the visual analogue scale, the duration of the operation and the occurrence of post‑operative morbidities. Out of 1,427 records, 15 articles with 729 participants (mean age, 10.2±6.7 years) were included in the study. The present systematic review supported the use of bupivacaine during tonsillectomy at a level of evidence of 1b and confirmed beneficial effects of bupivacaine intervention by demonstrating small to large effect reductions in the visual analog scale score (Hedge's g, ‑1.48), the mean duration of the operative procedure (Hedge's g, ‑1.35) and the incidence of post‑operative morbidity (Hedge's g, ‑0.23) in comparison to the placebo groups treated with normal saline. Based on these results, the administration of bupivacaine is recommended during tonsillectomies to reduce the perceived level of pain, the duration of the operation and the post‑operative morbidity.
