Objectives: To review literature on the use of hydrogen peroxide gargles in treating primary and secondary post-tonsillectomy bleeding (PTB), and investigate its rationale.
Method: A literature search was performed on PubMed and Medline databases. Articles in English focusing on hydrogen peroxide use in PTB were identified.
Results: 7 articles were found and 3 were selected. Two articles showed no correlation between hydrogen peroxide use and outcomes following PTB. One highlighted significant communal disparity in the use of hydrogen peroxide and the rationale for its use amongst ENT consultants.
Conclusion: Hydrogen peroxide use in PTB is prevalent, but without clear evidence if it works and through what mechanism. Further research must be undertaken to consolidate knowledge and make PTB treatment more efficient.
