Objective:This study aims to investigate the differences in hemostatic efficacy and patient comfort between an innovative domestically produced biodegradable nasal packing sponge and a traditional absorbent sponge following endoscopic nasal surgery. Methods:A prospective, randomized controlled trial design was utilized, including 30 patients who were divided into two groups according to random allocation, each receiving one of the two types of nasal packing. The study assessed the hemostatic efficacy, comfort, and safety of the materials by comparing the rates of no bleeding within 24 hours after packing, re-bleeding rates after 48 hours, pain ratings in the head and nasal areas, scores on a visual analog scale for nasal ocular symptoms, and safety indicators between the two groups. Results:The rates of no bleeding within 24 hours post-packing were 73.33% for both the experimental and control groups, with a no-bleeding rate of 100% after 48 hours in both groups. The pain rating in the head and nasal areas at various times post-packing was Grade Ⅰ（100%） in both groups, with no statistically significant difference（P=1.000）. The experimental groups sneezing score on the day of packing was（0.73±1.03）, lower than the control groups（2.27±1.67）, （P=0.007）; after 48 hours, the experimental groups sneezing score was（0.67±0.98）, also lower than the control groups（1.67±1.18）, （P=0.019）. There was no significant difference between the two groups in the Lund-Kennedy scoring during endoscopic examinations at the screening period, 7 days, 1 month, and 3 months post-packing（P>0.05）. Laboratory tests for other examination indicators were normal in both groups. Conclusion:The innovative domestically produced biodegradable nasal packing sponge not only provides hemostatic efficacy comparable to imported materials but also significantly improves patient comfort after surgery. It represents an economical and effective choice for nasal packing materials.
目的：本研究旨在探讨创新型国产可降解鼻腔填充海绵与纳吸绵在鼻内镜手术后止血效果及患者舒适度方面的差异。 方法：采用前瞻性随机对照试验设计，研究共纳入患者30例，按随机分组原则分为2组，分别使用2种海绵进行鼻腔填塞。通过比较2组患者填塞后24 h内无出血率、填塞后48 h无出血率、头鼻部位疼痛评级、鼻眼症状视觉模拟量表评分及安全性指标，评估2种材料的止血效果、舒适度及安全性。 结果：试验组与对照组受试者填塞后24 h无出血率均为73.33%，填塞后48 h无出血率均为0（100%），试验组与对照组受试者填塞后不同时间段头鼻部位疼痛评级均为Ⅰ级（100%），试验组与对照组差异无统计学意义（P=1.000）。填塞当天试验组“喷嚏”评分为（0.73±1.03）分，低于对照组的（2.27±1.67）分，（P=0.007）；填塞后48 h的试验组“喷嚏”评分为（0.67±0.98），低于对照组的（1.67±1.18）分，（P=0.019）。试验组与对照组受试者在筛选期、填塞后7 d、填塞后1个月、填塞后3个月进行鼻内镜检查量化评分（Lund-Kennedy评分），2组差异无统计学意义（P>0.05）。试验组和对照组受试者之间实验室其他检查指标均正常。 结论：创新型国产可降解鼻腔填充海绵在鼻内镜手术后的鼻腔填塞中，不仅提供了与进口材料相当的止血效果，还能显著提高患者的术后舒适度，是一种经济实惠且有效的鼻腔填塞材料选择。.
