目的探讨正颌术中口内正畸物品遗失的主要原因,并探究应用节点管理对降低正畸物品遗失率的效果。方法成立研究团队,分析术中正畸物品的遗失原因,探讨可能发生正畸物品遗失的术中环节,并制定控制措施。选取2018年6月至2019年1月的正颌手术患者763例,口内均佩戴有正畸物品。以2018年6月至9月的372例为对照组,采用传统清点流程;2018年10月至2019年1月的391例为实验组,采用节点管理;比较两组的正畸物品遗失率。结果应用节点管理后,实验组正畸物品遗失率明显降低,无效麻醉及手术时间缩短,差异均有统计学意义(P<0.05)。结论应用节点管理可有效降低正颌术中口内正畸物品的遗失率,保证正颌手术的顺利进行,对保障患者安全具有积极意义。

Objective To in vestigate the main causes for the loss of orthodontic items in orthognathic surgery, and to explore the effect of node management in reducing the loss rate of orthodontic articles. Methods A research team was set up to analyze the causes of the loss of orthodontic items during operation, and to explore the possible surgical procedures so as to develop control measures. From June 2018 to January 2019, 763 patients undergoing orthognathic surgery were selected,all of whom were wearing orthodontic items in their mouths. Among them, 372 cases undergoing orthognathic surgery from June to September 2018 were set as the control group, which adopted the traditional counting process. Three hundred and ninety-one patients undergoing orthognathic surgery from October to January 2019 were set as experimental group and node management was adopted. The loss rate of orthodontic items and work efficiency before and after intervention were compared.Results After the application of node management, the loss rate of orthodontic items in the orthognathic surgery were significantly reduced, and the ineffective anesthesia and operation time were shortened. The differences were all statistically significant(P<0.05). Conclusion The application of node management can effectively reduce the loss rate of orthodontic items in orthognathic surgery, promote the smooth operation of orthognathic surgery, and ensure the safety of patients.
