Postoperative Bleeding in Children With Tonsillectomy: A Retrospective Cohort

Background: It is necessary to evaluate the risk factors of secondary bleeding after tonsillectomy in children, to provide reference for clinical children management and care. Methods: Children who underwent tonsillectomy from January 1, 2018, to December 31, 2022, in our hospital were retrospectively included. The characteristics of children with and without secondary bleeding were analyzed. Results: A total of 1068 children undergoing tonsillectomy were included, and the incidence of secondary bleeding children undergoing tonsillectomy was 4.87%. Age ≥ 9 years old (odds ratio [OR] = 2.609, 95% confidence interval [CI] = 2.112-3.437), type of surgery (OR = 1.764, 95% CI = 1.148-2.291), and degree of tonsil embedding (OR = 2.116, 95% CI = 1.805-2.644) were the risk factors of secondary bleeding after tonsillectomy in children (all P < .05). Conclusion: Medical staff should proactively monitor and address the identified risk factors by implementing timely warning systems and preventive strategies to reduce the postoperative bleeding following tonsillectomy.
