Conclusions: Our study suggested that the major risk factors for postoperative bleeding after nasal endoscopic surgery (NES) included hypertension, long-term non-steroidal anti-inflammatory drugs (NSAIDs), and previous nasal surgery. The use of preoperative corticosteroids is a valuable measure for reducing postoperative bleeding after NES.
Objectives: To explore risk factors for postoperative bleeding after NES and find effective measures to reduce or prevent the condition.
Methods: A total of 641 patients who underwent NES were analyzed retrospectively. Univariate analysis and logistic regression were performed to find potential risk factors.
Results: The incidence of postoperative bleeding after NES was 8.4%. Multivariate logistic regression analysis revealed that the occurrence of postoperative bleeding after NES was positively associated with hypertension, long-term NSAIDs, previous NES, and modified submucosal septoplasty, but negatively associated with the use of preoperative corticosteroids.
