ARTICLE HIGHLIGHTS
Research background

Tonsillectomy is the most common procedure for pediatric recurrent acute tonsillitis and tonsillar enlargement that contributes to obstructive sleep apnea hypopnea syndrome. Postoperative hemorrhage of tonsillectomy is a life-threatening compli-cation.

Research motivation

To improve the management of postoperative hemorrhage of tonsillectomy.

Research objectives

To identify the risk factors that may contribute to primary and secondary post-operative hemorrhage in pediatric tonsillectomy.

Research methods

A retrospective analytical study was performed, which included clinical data from 5015 consecutive patients who underwent tonsillectomy from January 2009 to December 2018. Characteristics of the patients from the primary bleeding group and the secondary bleeding group were compared with those of the nonbleeding group separately.

Research results

The method of tonsillectomy and experience of the surgeon were significantly associated with primary hemorrhage, while age and time of onset were significantly associated with secondary hemorrhage. There was a significant difference in the intervention measures between the primary bleeding group and the secondary bleeding group.

Research conclusions

Coblation tonsillectomy and junior surgeons contribute to the tendency for primary hemorrhage. Age and time of onset are responsible for secondary hemorrhage.

Research perspectives

The incidence rate of post-tonsillectomy hemorrhage is low, and lethal hemorrhage rarely occurs. The risks of postoperative hemorrhage should be given more attention.
