Abstract:

Objective To design a maxillofacial dressing hemostatic bandage based on the airbag pressurization principle and evaluate its clinical efficacy in patients with maxillofacial injuries. Methods A randomized controlled trial was conducted involving 40 patients requiring maxillofacial bandaging and hemostasis who were admitted to the Department of Oral and Maxillofacial Surgery at a tertiary general hospital in Beijing from November 2024 to March 2025. Using a random number table method，patients were randomly allocated to an experimental group and a control group in a 1∶1 ratio. Each group consists of 20 cases. The experimental group received bandaging with the maxillofacial compression hemostatic bandage，while the control group was treated with elastic bandages. Bandaging time，frequency of unplanned rebandaging，and General Comfort Questionnaire（GCQ） scores were recorded for both groups. Results There were no dropouts in either of the 2 groups. Regarding bandaging time，the experimental group showed shorter duration compared to the control group，though the difference was not statistically significant（t=2.016，P=0.051）. For unplanned rebandaging frequency，the experimental group demonstrated significant-ly fewer instances than the control group，with a statistically significant difference（Z=-5.029，P<0.001）. In terms of GCQ scores，patients in the experimental group showed significantly higher comfort levels compared to the control group，with a statistically significant difference（Z=-2.456，P=0.014）. Conclusion The use of maxillofacial dressing hemostatic bandages based on airbag pressurization principle for bandaging and hemostasis in patients with maxillofacial injuries effectively reduces unplanned rebandaging frequency and improves patient comfort，demonstrating favorable clinical application outcomes.

摘要： 目的 基于气囊加压原理设计一种颌面包扎止血巾，并探讨其在颌面部损伤患者中的应用效果。方法 采用随机对照试验设计，2024年9月—2025年3月北京市某三级甲等综合医院口腔颌面外科收治的40例需进行颌面部围手术期出血的患者作为应用对象。通过随机数字表法，按照1∶1的比例将纳入研究的患者随机分为试验组与对照组，每组各20例。试验组采用颌面包扎止血巾对颌面部伤口进行包扎，对照组采用弹力绷带包扎。比较两组的包扎时间、非计划重复包扎次数以及舒适状况量表评分的差异。结果 两组无样本脱落。两组包扎时间比较，试验组包扎时间低于对照组，但差异无统计学意义（t=2.016，P=0.051）；两组非计划重复包扎次数比较，试验组低于对照组，差异有统计学意义（Z=-5.029，P<0.001）；两组舒适状况量表评分比较，试验组舒适度高于对照组，差异有统计学意义（Z=-2.456，P=0.014）。结论 使用基于气囊加压原理的颌面包扎止血巾对颌面部损伤患者进行包扎止血，有助于减少非计划重复包扎次数，提高患者舒适度，具有较好的临床应用效果。
